T41 Freezing-

Hello Folks,
I hope some of you having good technical knowledge on Thinkpads and can help me in resolving my T41 Freezing problem.
T41-2372 model started giving me some problem few days back.
It just don't boot up or don't shows anything on the screen when powered on.
I tried removing Battery, DVD Rom, HDD as well still no luck. It works fine some times if you try 4/5 time power ON / OFF that too if you are lucky and the Laptop should be lyint still, if you move it a bit its screen freezes and had to hard boot.
it's not HDD for sure I know as I said , even after removing HDD its not working.
Before freezing screen shakes like bar grafh of earth quake and its gone.
Any help will be greatly appreciated.
Thanks & Regards
Kevin

Kevin, welcome to the forum,
It sounds as though, regretably  , you are suffering from the T4* flexing / loose GPU syndrome. Have a look in TPF's T4x Series board, especially the sticky "t42 shuts down when I move it".

  • Freezing and flickering of the screen on a T41

    Hello
    I bought a used T41 about a year ago, and changed its hard drive from a standard 40 gb to a 120 gb one (dual boot WinXP/Ubuntu, did not use the recovery console to reinstall windows, rather used my own copy and downloaded the drivers from the Lenovo website). The computer worked fine up until a month ago, when, in the midlle of browsing, the display on the screen started to "shake" (kind of hard to describe, but was it was like a shearing and some fuzziness). I turned it off and turn on again and the computer would either not boot, or would boot normally and would show the same symptoms as above randomly (smtimes after 5 min, sometimes after 2 hrs). This was the case when the computer was plugged in (with or without the battery attached) or just on battery powe. I am startin to think that it might be a problem with the display adapter, which i think means i would have to replace the whole mobo. I am just posting here to see if anybody has any suggestions either via knowlegde or prior experience.
    Thankx in advance

    oh, and i forgot to mention the most imprtant part. When the display was "shearing", there was no response from the computer (mouse cursor not moving, could not type), which seems to suggest that is not just the screen ( i have had it connested to an external monitor as well and had no luck either

  • At the start of a song, iTunes freezes and it stutters

    With the new install of iTunes on Windows XP, it consumes more than 97% of CPU at the start of a song with the result that the song plays like as if some one is stuttering the song and I hate it. It was never an issue with the earlier version of iTunes. The newer version also consumes 17-20% of CPU to play a song and this was not the case either earlier.
    Is there a workaround to this? I have an IBM T41 laptop. Nothing has changed on my laptop except that I have a newer version of iTunes.
    Your help or thoughtful ideas are appreciated except the suggestion to buy a newer and faster laptop or switch to Mac OS.

    I had this problem with the freezing and stuttering. I solved this by unchecking 'crossfade playback' in edit/preferences/playback. It means you have a pause between songs during playback, but thats like most CD players anyway.
    Hope this helps you.

  • T41 won't hibernate

    Up til recently, my T41 hibernated with no problem. Hit the fn f12 combination, and away it would go.
    Suddenly, it shows the hibernation screen, then aborts completely. I've deleted and recreated the hibfil.sys file in c:, but that didn't help. I run XP.
    Any ideas?
    Solved!

    To anyone else still tearing out their hair trying to solve this (as was I), here is the solution.  The problem is most likely rootkit malware attack.  If combofix freezes up your computer, try the following instead.
    To check and remove rootkits, download and run Kaspersky's TDSSKiller:
    http://support.kaspersky.com/downloads/utils/tdssk​iller.zip
    I ran this.  It found one infection, quaranteened the file, rebooted my computer, and hibernation now works.
    After countless attempts to fix hibernation, this was the only solution that worked for me.

    Welcome to the forum.
    Sounds like a motherboard problem...try connecting the machine to an external monitor and see whether it displays anything when turned on.
    Good luck and keep us posted.

  • T61p freezes randomly when on Battery Power

    I recently got my new T61p and i'm absolutely loving it. However, randomly (and only when the laptop is not plugged in to AC power) the system will hang on certain tasks, usually web surfing since thats what I'm usually doing, and I'll have to do a hard reboot. Consequently, internet explorer and mozilla firefox tend to freeze sometimes when I'm on battery power. When I'm plugged into AC power everything runs perfectly.
    According to this website http://www.utheguru.com/lenovo-ibm-t41-random-crash, this guy had similar problems with his t41. I have all the latest versions of power management and updated all drivers and patched vista. Any ideas on what to do? I don't want to uninstall power management b/c its so useful
    edit: I use the 'Energy Star' profile for my power setting
    another edit: Apparently it is to do with the Intel turbo memory. i'll try the solutions in this post and give u my progress: http://forum.thinkpads.com/viewtopic.php?t=51908

    I got my T61p last Friday.  I'm having the same issues after applying all patches and driver updates.  I can run fine on AC power, but as soon as I unplug the machine, the screen goes blank and I have to do a hard reboot.  I have not been using Turbo Memory.  For a few days it worked just fine, but then the problem started up again yesterday.  I think it has something to do with the GPU.

  • Install of 8.6 or 9.0 freezes

    Tried searching for a bit, but I didn't see anything in this forum that helped. If I missed something, I apologize--please point me in the right direction!
    Got out the old beige G3 to play around with the other day. I decided I wanted to attempt to install OSX on it since I've got a zif 1Ghz upgrade sitting around and some extra hard drives.
    My tale begins with a fairly stock G3. The original (I'm guessing) 6GB hard drive is an Apple OEM drive, but it has passed on. It had OS 9 on it and was running fine. Since the drive died, I decided to start with a new hard drive and 8.6 since the tower (by the way, it's a Rev. A) came with 8, right? I figured, perhaps wrongly, that the best path to OSX would be by running all the proper updates through OS 9. Sounds like 10.2 is fairly stable for the G3 tower without lots of tweaking, so that's what I was shooting for.
    Well, here's what I did to prepare the drive and computer:
    Pull extra RAM
    Pull personality card (only card installed)
    Replace PRAM battery
    Set drive and CD-ROM to master
    Boot to open firmware (set-defaults, reset-all)
    Reset with p-r-opt-cmd dance
    Then I booted to the 8.6 install disk. I ran disk setup and initialized the 80GB ATA drive (WD Caviar) with two partitions (7GB and 73GB roughly) since I was planning on working my way up to OSX and have read about the 8GB partition limitation. Just in case I installed the drivers for the disk with drive setup after I initialized it.
    Restart, boot to 8.6 install disk. Run the installer, selecting the ~7GB partition. It freezes with four minutes left. That's not good!
    I had three RAM modules, so I started from scratch and ran the whole procedure from top to bottom with each module. Same thing.
    Tried the OS 9 install disk. At this point, I was a little frustrated. Maybe my install disk was messed up. Nope. OS 9 install freezes with seven minutes left every time.
    Is it possible that all three RAM modules are corrupt? This computer has been sitting for quite some time. The PRAM battery was toast, hence the replacement. Oh, and by the way, the only things hooked up are the CD-ROM and hard drive. No ZIP or floppy attached during the installation attempts.
    Am I missing something super obvious?
    Thanks for taking the time to read this poor tale. I look forward to being enlightened.
    b

    Jon - My goal now is to get this machine back to where it was in the not so distant past. I'd prefer not to start pouring money into it if I'm not sure that it will work. I'll keep that in mind if I do find a solution to my problem, or if I can fairly definitively narrow my problem down to the motherboard.
    BDAqua - Thanks. I knew the reset-nvram didn't work on this firmware, and I--probably mistakenly--assumed that doing the p-r-opt-cmd dance took care of that reset. I'll try that in about an hour.
    While I'm sitting around, I decided to test one more variable--the CD-ROM drive. Booted to the OS9 disk and initialized my 80GB disk. Then I used Disk Copy to copy the CD to a later partition. I'll install 8.6 until it freezes. Believe it or not, it'll show the flashing disk with question mark, and eventually boot 8.6. This is not so with OS9. If I let that install until it freezes, it won't boot at all. So I'll try to boot up 8.6 with another hard drive attached, and attempt to run the OS9 installer to install on the other hard drive. At this point I'm grasping at straws. I'm not even sure the installer will run if it's not on a CD.
    So I'll try the reset after this (probably fails).
    thanks!

  • MSI VN220GT MD1G|GeForce 220 GT - causing lock ups/screen freezes

    Hi, I've been searching everywhere for my problem, and the things I find usually are left unanswered :(
    I recently upgraded my old graphics card (GeForce 7300 GT) to the GeForce 220 GT, at that time I was using Windows XP SP3. Everything went fine then, I downloaded the newest driver from nVidia (195.62) and restarted, everything went smoothly.
    It was then my computer started to freeze, to the point where I can't do anything (mouse/keyboard unresponsive). I am forced to force reboot. This freezing usually happens randomly when there's nothing to provoke the problem.
    So I decided to upgrade to the new Windows 7. I did everything it told me to and everything went very well. But the problem still occurs, but more often, and around 30 minutes after logging in. I got the Windows 7 32 bit version of the new nVidia driver (195.62) and installed it. Did nothing. I have also tried to update windows which also did nothing.
    These forum threads ask the same question I am now asking:

    I did some more research on the net and it seems this PSU is labelled under many different names. I found a Portuguese site that did the test for this unit and then used the google translator tool.
    refer to http://www.clubedohardware.com.br/artigos/1818/1
    Some translated extracts:
    The Coletek is a national brand aimed at the OEM market, or its source is aimed at companies that assemble PCs They have a separate brand for products geared to the retail market, the C3Tech. Today we test the model LC-8460BTX S (which, despite its name, is an ATX and not a BTX) that is sold as a source of 450 W. Really?.....
    ....Speaking of curiosity, in Figure 7 you can see the marking of the type of fuse in the circuit board of the source. All sources bring this information. But the curious thing here is that the marking indicates that for a source from 150 to 200 W a 5 A fuse should be used and to a source from 230 to 300 W from a 6.3 A fuse should be used. As this power supply uses a fuse of 6.3 A, we have a source between 230 and 300 W, according to their own existing markup on the printed circuit board thereof. As the manufacturer can turn that into 450 W on the label of the source is a magic that Mr. M can not explain.....
    ....The Coletek LC-S 8460BTX burned when trying to draw about 225 W (which would be our test number seven). So the most you can pull it was about 190 W (which would be our test of 200 W). More information and video on the next page.
    So I recommend that you perhaps translate the whole article to get the full results. In your case, I believe the PSU should be the first place where you should try something a bit more realistic before you do anything else.
    Quote from: Henry on 15-January-10, 08:09:28
    For a system with a 220 installed PSU with +12V~30A minimum is recommended. My recommendation is to get nothing less than a quality PSU such as a Corsair VX450W +12V~33A. That junk PSU is typical of the worthless ones that are often provided by case manufacturers and examples of similar units that can be purchased for as little as $10 (USD) on eBay.
    Thank-you so much guys, you've most likely have just diagnosed and gave me a solution for my problem
    At first I never knew all PSU's were different, and that my new graphics card could handle whatever I had in my system at the moment.
    I don't think I will bother checking my PSU if my current PSU is a Okia or a Xion, I may as well upgrade the thing anyway
    Just some things I need cleared up though:
    Firstly, is it the Corsair VX450W that I would want to buy and install to run my card? Is it affordable?
    And secondly, are PSU's hard to install/upgrade? Where can I find a guide/tutorial for this kind of thing?

  • Lock-ups/freezes - Nvidia GeForce 8600M GT

    Hi all, I have been the owner of a MacBook Pro since August or so. My problem is that when working with my MacBook Pro, occasionally the display freezes up. Sometimes it recovers, sometimes the machine refuse to recover. If I listen to iTunes, I hear the music playing on in the background, which indicates that this is an issue with the graphics chip, and not the computer in general.
    I have searched the Internet, and it seems I am not the only one who has issues with the Nvidia GeForce 8600M GT. According to slashdot.org, Apple acknowledges that this may be an issue (http://apple.slashdot.org/apple/08/10/11/1518246.shtml).
    Have anyone else experienced these kinds of issues, and if you did, how did you solve them?

    Hello! I am feeling a little more secure now that there have been quite a few posts about the poor preformance of the nVidia cards in the SR Macbook Pros, its comforting to know this isn't an isolated issue. I've gone as far as contacting Apple to let them know of the poor preformance. They've were, as usual, very nice and as helpful as they are allowed to be. Currently, I have a replacment on the way apparently, my original was deemd DOA I believe. However, it seems at the time all we can do is report our issues to Apple. My main concern is the legnth of time these machines have been out, and the amount of units sold to unknowing customers who are being sold on what Apple is marketing as a strong feature of the machines: the graphics card. When in reality, the card is extraordinary, the preformance in OSX is extremely poor. It is up to us as consumers to let Apple know how aggrivated we are.
    Please, take the time and send your responses and feelings to Apple. You can do that here:

    I just recently started having problems with my computer, im not sure why this happend but ill try to explain everything as best as I can.
    The problem started a few days ago while I was playing SWG's. I was playing and all of a sudden my machine froze, the screen locked-up and then after about 2 min the entire system restarted. I then logged back into my windows and after a while a system froze and restarted yet again. I though it was a SWGs issue but then the computer would freeze while browsing the net and doing other tasks.
    I have formated my machine, re-installed my drivers, and re-installed the hardward. Nothing has worked.
    My computer specs are
    300watt PSU Enermax True Power

    If what you are saying, and I am reading correctly:
    The machine and game was working just peachy and all of a sudden the problem manifested itself?
    Did you do ANYTHING to change your system prior to this happening to possibly have an effect?
    the fast that you said you have re-loaded the OS and removed and re-installed the hardware with the same result tells me that there may be some sort of hardware failure and this could get difficult to troubleshoot.
    First things first, try a memory testing software like memtest86 to see if you get any errors.

  • Pavilion Elite e9180f freezes, crashes, BSOD

    I am one of the many unhappy customers who bought this piece of junk (Pavilion Elite e9180f) and waited too long to return it because in my naivete, I thought it was some kind of simple software issue.  Nope!  It's definitely something wrong with the hardware, because the freezes and crashes have been happening since day 1, right when I took the thing out of the box.
    Yeah, the system is fast and runs Windows Vista great, when it's actually WORKING, which is usually only guaranteed for about the first 5 minutes after you power the system on and boot windows.  After that, it's just buying time before it crashes again.  Forget trying to get anything done on this computer.  Forget about asking this PC to play a video or music file without the files "stuttering" during playback.  Even my 7 year old Sony Vaio which is running XP can handle playing an MP3 file without stuttering and crashing!
    Like everyone else, the freezes and crashes happen either one of two ways:
    1) The machine begins to "stutter", stutter more, then freeze/crash.  When I say stutter, I mean I move the mouse, the pointer graphic will hesitate on the screen and lag behind.  If you start to play a video or music file, this manifests in an audible "stutter".  The stuttering gets worse and worse as minutes pass until eventually it freezes for good, blasting that 1/50th second moment of audio into infinity.  You have to reboot immediately if you don't want to go deaf or be driven mad.
    2)  I will be doing nothing at the time (example, I close all programs out and leave Windows sitting on the main desktop screen), I'll walk out of the room for a minute, then come back and find I can't move the mouse. This system will often lock-up without any warning!
    Sometimes I'll get a BSOD or error screen, sometimes I won't (in which case your only option is to do a cold re-boot.)  When I do get the BSOD, the error is ALWAYS the "did not get a response from the secondary processor" yada yada.  I wish HP would just admit they shipped this model out with a bad processor/motherboard/whatever and do an official recall.  I have owned PCs for the last 13 years and this is the worst and most consistently disappointing experience I have ever had.
    What is the hardware issue?  Which part is the lemon part?  The motherboard?  The processor?  The BSODs seem to indicate a bad processor.  I do have the Pegatron Truckee version 1.03 motherboard.  Is that the problem?
    P.S.  I have contacted HP on many occasions about this, literally stayed on the phone for hours with "customer support" (according to one HP rep, 80% of their customer service reps are based outside of the United States...good luck getting any "technical" help from them) to no avail.  I did talk to one nice tech support guy in Canada who said "it sounds like your unit has a bad processor", so he had HP send me a box to ship my unit to their repair center so they can replace the processor.  However, I have also had HP reps tell me it could be anything from the memory to the hard drive.  Multiple HP reps claimed to me that they have "received no complaints" about this system.  One guy told me he "thought he got an email last week" regarding "something" about the system, but couldn't remember what it was and he put me on hold while he searched for the email.  He never found it.  What a joke.
    EDIT:  Just to clarify, the crashing issue has been happening since day one, but initially I thought it was an issue with Vista.  I had never owned or used Vista before, so I thought maybe Vista was just unstable.  Nope.  I know several people who own Vista and have never experienced these issues.  I have downloaded every update from Microsoft/Windows Update.  I have upgraded to Vista SP2 with all the latest drivers and software for all of my hardware.  No luck.  It is definitely a hardware issue.  Thank god HP's warranty is good for 1 year (I bought my Elite in July).

    Unfortunately I have to add my disastrous encounter with HP's E9180F a true lemon HP is selling. I must take some responsibility for not carefully researching this model before I purchased, but I trusted the HP name and got stung- big time.
    The scoundrel  :
    HP and its Pavilion Elite e9180f
    Windows 7 64bit
    motherboard - Pegatron  Truckee ver 1.03
    BIOS ver  5.22Intel Core i7 920 @ 2.67GHz
    Memory 9206 MB Ram   
    As so many others have reported my HP E9180f started locking up and going to BSOD right out of the box. My first freeze-up came when I was doing the Windows update process. At first I didn't think much about it but I started getting random freezes a couple time a day. At that point I went online to see if others had experienced the same problem and perhaps had a fix. What I found was very troubling;  I found extensive documentation describing my exact problems and what was really horrifying was the reports of how ridiculous HP's help services were treating people with the problem. At first I didn't totally believe what I was reading on HP's own customer forum; I do now.
    ·         I've went through the total recovery process three times now, HP techs have spent hours remotely running my computer, (yes it did lock up on them to)
    ·         I had to upgraded the BIOS. (HP tech tried, said he had, but he hadn't)
    ·         I was directed to clear the BIOS (luckily for me I had the tools
    ·         Updated all drivers again and again.
    ·         Next I was asked to remove the video card, memory, and motherboard power cable and reseat them. I declined because I didn't want to give HP any reason to void my HP 2 year House Call Care Pack which covers this unit. When I invited HP to send a service tech out to perform these tasks, they said that house call only covers part replacement, we weren't replacing a part. I couldn't believe what I was told. Are you feeling my frustration?  
    Keep in mind that each time HP requests that I make changes, they then ask me to test the system, which I did and each time with the same result, BSOD
    I'm heading into my fifth week of working with HP to fix this problem. and I still haven't even been able to get my case moved up to a senior case manager, what a joke HP's help process is.
     One conversation I loved was;
    HP tech: "I'll have a senior case manager call you within 24 hours."
    Skeptical me: "What should I do if I don't get a call?"
    Silence, no response.
    Me again: "What should I do if I don't get a call?"
    HP tech: "That's an impossibility."
    Guess what? The impossibility became reality (I bet you guessed) .
    HP's last stall tactic was to have me fax them my proof of purchase and invoice and call back in 24 hours. Where have I heard that before? Apparently nothing can go forward until they receive it. So I faxed them the stuff within 10 minutes, and when I called back 24 hours later, guess what, you're right it wasn't on their system yet. I asked couldn't I be escalated to a senior case manager  (it's apparent that only a senior case manager can do anything). "No," was the tech's reply, "call back again later".
    Please if anyone out there knows the secrete to getting a senior case manager, or an HP tech support number here in the U.S. so I can get this thing fixed I'd love to know it.
    Fast becoming HP never again.      

  • Mid 2009 13.3" Macbook Pro random freezing issue

    Hi all,
    I had a 2009 13.3" Unibody Macbook and last week purchased a 13.3" Macbook Pro. I had installed 4GB of RAM in the MB myself, and it had worked fine for the month I owned it.
    I backed up my MB with an external USB hard drive using Time machine, restored from this backup on my MBP and moved the 4GB RAM over.
    When using the MBP I get random freezes lasting between 1 and 3 seconds, occuring every 5 to 30 minutes.
    Could someone please advise a good way to diagnose this problem further? I am guessing it is not the RAM as it worked fine whilst in the MB.

    I have an update!
    I made an appointment with a local Apple Genius Bar and talked to a technian. He said it was neither the RAM nor the Hard Drive at fault.
    His only thoughts were that a software issue was the root cause. I have been doing some serious investigating this morning and figured it out. Viewing system.log in Console shows:
    SMS::infiniteIntTimerEventHandler ERROR: we have infinite interrupts, disabling
    At exactly 5 minute intervals. These correlate with the freezes (to the second).
    SMS refers to the Apple Sudden Motion Sensor. I disabled this by doing "sudo pmset -a sms 0" in Terminal, rebooted and everything is fine.
    I have no idea why the SMS thinks the Macbook is falling every 5 minutes, but when it occures the hard drive heads are locked down to prevent damage, which is a perfect reason as to why iTunes would crash but Spotify (streaming internet music) does not.
    Problem solved!
    Edit:
    In reply to some questions posted by other members (thank you by the way).
    I did install EFI 1.7 update. I did not use the Migration assistance. At some point I will do a fresh install then pick and choose parts from a backup rather than using a full Time Machine Restore. This could still have been the root cause of the issue, but it is hard to tell.
    Thanks guys!

  • Mid-2009 MBP Has Been Hard Freezing, I think it may be the SSD or software?

    Please read this fully so you don't end up suggesting something I've already tried.
    I have the Mid-2009 version of the 13" MBP that I received in December 2009. Almost two years ago, I upgraded it to8 GB of RAM and a 256 GB SSD. Everything has been running smoothly until about 2 or so weeks ago. My computer has been having hard freezes, meaning, it's not simply an application freezing up; force quit doesn't work, the clock stops ticking, the whole system freezes. It was very predictable too. Whether i was watching youtube videos with flash, reading online articles without it (I have ad block) or doing something completely non-flash or web related, my computer would hard freeze after about an hour or two or so of use, requiring a hard reset (holding the power button until it turned off and then restarting).
    I did some research on this and from what I initially found I thought it was problems with the motherboard. However, I found that to be odd because my motherboard was replaced by Apple in September 2012. I read somewhere to try a system hardware diagnostic test (press D upon start up). On the short hardware test, the one that only takes a few minutes, it passed without any problems. Then I tried the longer hardware test, the one that says takes more than an hour. I put that one on and left it alone. I came back every so often and checked on it and it was fine at first. The mouse responded and the test was showing some measurable progress. However I came back, and at 2 hours 11 minutes and 59 seconds into the hardware test, it froze without completing it.
    Then I tried doing something everyone says to do when anything happens: I repaired disk permissions. I did that, and according to Disk utility everything went rather swimmingly. However, that didn't fix anything,in fact, it made things slightly worse. Ever since I reset disk permissions, everytime I open Safari, it freezes immediately, and that has only happened since I repaired disk permissions. My home page is about:blank, if anyone was wondering. I've only discovered this happening with Safari as of now. I switched Chrome as my primary web browser for now.
    Being the resourceful person I am, I tried to isolate the problem. My sister, luckily, has an identical MBP. First, using target disk on my computer, I booted my SSD onto her computer - this is to see if the problem was HDD/SSD related or motherboard related. When I booted my SSD onto her computer the same problems occurred: Safari froze upon start up, and then computer would hard freeze after about two hours. However, when I booted her HDD onto my computer via target disk, there were no problems. Safari opened just fine and I used her computer for several hours without issue.
    At this point, I was pretty sure it was the SSD, but I thought it was possibly a bad Sata cable or something. But nope. Last night, I switched harddrives completely. No target Disk. I put my SSD in her computer and put her HDD in my computer. I got the same results as target disk. It can't be the motherboard or memory, because both computers worked fine with my sisters harddrive. Only the computer booted off of the SSD would have these problems.
    At this point I think it could be two possibilities
    A) Either the SSD itself is starting to become defective
    B) Some software component of my SSD is buggy
    I think it could be something software related because why would Safari and safari only freeze after launch, but no other apps? Also something of note, these problems were happening, I tried to see if doing anything with software update would help, updated everything that needed to be updated, and these problems still occurred.
    What do you guys think? anyone have an idea of what it could be? Any suggestions of how I handle this? Applecare is expired. I'm considering doing a clean install but I'm not fully backed up yet and I don't want to waste my time and have it not work. But I also don't want to buy a new hard drive or SSD and have it do the same things. And I'm not getting a new computer if the only problem with it is contained within the storage unit, whether that problem is within the software or hardware related.
    Responses and suggestions would be highly appreciated, thanks.
    EDIT: this information may be of interest: currently have 19.51 GB of available space (out of 256 GB). At one point, about a month and a half or so ago, my storage was as low as 9 or so GB free.
    I am running OSX 10.6.8

    I have tried making a new user account like you suggested. It fixed the Safari problem; Safari opened and played video just fine. However, the computer still hard freezed after about 2 hours. I am about to back up my computer via time machine after this (hopefully it'll finish before it hard freezes again, I haven't backd up in more than a year). If that doesn't work, I guess I'll have to move folders individually onto an external. I will proceed after backup with a clean install as that is my only other option for now.  
    However, after a clean install, should I restore directly from time machine? I would think wiping the hard drive and replacing it with what's on time machine wouldn't solve the problem because the inherent corruption is being restored. However, what about just restoring my User folder? What would the process be for getting everything back to normal as quickly as possible? Do you know of any good ways to get my apps and other preferences back to normal ASAP without corrupting anything? Will I have to re-register anything? For example, I have Adobe CS4 that I received from my highschool IT department. I have since graduated, so I don't have the disc or any of the password codes. Would it be risky to restore the application support folder (because that's where the bug may lie)? Or if I just drag just drag apps, would that still work or is the application support necessary too?

  • Mini-DVI to VGA - online video freezes when dragged from MacBook to LCD TV

    I connected my MacBook to my LCD TV this morning via Mini-DVI to VGA, and am trying to stream online video. The video works fine when the browser is on my MacBook screen, but when I drag it over to the LCD TV, the video freezes. I tried setting the screens to mirrored as well, and the video wouldn't play (on either). I'm not really sure what else to try. Any help would be appreciated!

    Try this...
    With the TV connected, go into Displays Preferences and click on the Arrangement tab. You should see two blue rectangles meant to represent the two screens. One of the rectangles will have a white bar across the top, meant to represent the menu bar. Drag the small white bar from one blue rectangle to the other. This will move the real menu bar to the TV, making it the primary display. Now see if your video will play on the TV.
