Memory going bad???

My K7T266 Pro2-RU system has been running stably since I built it last November. However, yesterday I started getting frequent system lock-ups, and I couldn't find anything I had done that would have caused it. I found that I could reproduce the problem when booting a Win98 floppy and running the MEMTEST program, which pretty well ruled out anything in WinXP. Then I discovered that changing the FSB from 133 down to 100 "cures" (groan) the problem (I'm running an XP1500+ and one stick of PC2100 DDR RAM). It's very repeatable - MEMTEST locks up at 133, works fine at 100. My question is this - could this be the memory module going bad, or is some other degradation more likely??? [All components are high quality, no recent H/W changes.]

Speed Fan shows +3.3V=3.26-3.31, +5=4.95-5.0, +12=12.16-12.22, -12=-12.12 to -12.03, -5=-5.35 to -5.45
Looks like the problem is NOT with the memory - I picked up another stick (Micron vs. Crucial) and see the same situation. Also tried BIOS 3.4 and 3.6. System seems to work fine at 100 FSB (now with 512MB!), but it's irritating!!

    I found a post with this solution that worked for me - .Do a backup, then download ibackupbot. It lets you look into the contents of that backup. Look in system files>mediadomain>library>sms>attachments. I found a ton of huge files related to long deleted texts. ibackupbot let me delete all that old crap. I then restored the phone with that now modifec backup and Bingo! freed up 9 GB. No problems.
    But note, if you are not technically inclined you probaly don't want to be digging around and deleting back up files. You delete the wrong thing and you could jack up your phone badly. Be careful.

  • Hi having problems with my screen output right this momemt it varies from clear to sgva quality with occasional streaks of purple flashing through it while i am typing this is my screen going bad just updated nothing has been spilled in or on it.

    currently clear and ok.  Could my screen be going bad after only four years?  output resolution this after was poor no better than a PC jr of the 80's went in and recheck my perferences and they seem all in order.  Only thing I can come up with is a video card going bad or screen malfunction.  Going to take in to genius bar.  I Don't think I have any malware on it.  Anybody with any ideas.  Need this machine to complete my college courses in photoshop and illustrator.  Only have 2 gigs of memory but that has worked fine up till today.  Occasionally screen is darken on the edges till I jump into a program or the internet.  Thanks for any suggestions  Douglaswilliams1@mac .com

  • My memory goes down for no reason?

    When my memory gets to under 4 GB something acts on my computer where it wants to eat up all my memory then within seconds I see it go down little by little then eventually goes to 0 kB and sometimes it stops randomly, but if I happen to restart my computer, the memory goes back up.
    why does it decide to do this and how can I fix it?

    You most likely have an application that has a memory leak and starts consuming more and more RAM. Open Activity Monitor, select All Processes from the Processes drop down menu, click on the Real Memory column twice to display in descending order. Watch for the topmost entry to see if the amount of RAM it uses is increasing as you are using your computer. This may help identify the culprit.
    Another possible cause could be a bad cache file. You might give the following a try:
    Boot into single-user mode. After startup is completed you will be in command line mode and should see a prompt with a cursor positioned after it. At the prompt enter the following then press RETURN after each commandline:
    /sbin/fsck -fy
    If you receive a message that says "*** FILE SYSTEM WAS MODIFIED ***" then re-run the command until you receive a message that says "** The volume (nameofvolume) appears to be OK." If you re-run the command more than seven times and do not get the OK message, then the drive cannot be repaired this way.
    If you were successful then enter:
    /sbin/mount -uw /
    rm -rf /System/Library/Caches/*
    rm -rf /System/Library/Extensions.kextcache
    rm -rf /System/Library/Extensions.mkext
    rm -rf /Library/Caches/*
    reboot
    I suggest you print out the above to be sure you do not make any errors when entering the commands. When in single-uwer mode you have 'root' access, so it's important that you not make any mistakes.

    To transfer your current hard drive I like the applications Carbon Copy Cloner or SuperDuper. They make a bootable copy of everything on your hard drive. http://www.bombich.com/index.html or http://www.shirt-pocket.com/SuperDuper/SuperDuperDescription.html 
    You'll need a cheap SATA external hard drive case. Put the new drive in the case then format and partition the new drive and clone your old drive to the new one. Check that it's set up right by booting up from the external drive. Then replace your old hard drive with the new one and put your old one in the external case.

  • I think the DVD player reader on my Mac is going bad. Is there a way to copy the files off of an Apple Install DVD onto an external drive and then do theinstall from the external drive?

    I think the DVD player reader on my Mac is going bad. Until I get it fixed Is there a way to copy the files off of an Apple Install DVD onto an external drive and then do theinstall from the external drive? It's ILife 11 if that makes a difference. Finder won't let me see the files to copy. I know - dumb question.
    Thanks.

    Adding an SSD is not a simple endeavour like adding additional memory or adding another hard drive to a Mac Pro. That's probably why the option is only offered as an option at the time of purchase. Even if your Apple store was willing to install the necessary parts you will probably be paying for 1-2 hours of labor plus the cost of purchasing the necessary service parts (SSD, bracket, cables, etc) which I suspect will make the upgrade cost much higher than what it costs to add the SSD option when purchasing a new system.
    I use my system for business and need it to work reliably.  Even though I'm fairly handy with tools I would not be willing to risk damaging my system and voiding my warranty by opening my system and removing the logic board and several other parts in order to squeeze in an SSD option and attach the appropriate cables and brackets. I'm also not prepared to deal with the hassles of explaining why my system has unauthorized parts installed in the event I experience issues and need to make use of my Apple warranty. My time is valuable, so I would probably investigate external storage options, or if I needed the speed of an SSD, I would consider selling my existing system and then purchase a new system configured with an SSD.
    If you haven't already done so I suggest doing a search on 'iMac SSD installation' to see what's involved. It might help you understand why the SSD option is not offered post purchase.

  • Screen goes black, shut the lid for a few minutes, open the lid the turn on chime comes on and the screen comes back to life. The computer itself has continued to update just no screen. After a few minutes goes black again. Is logic board going bad?

    Screen goes black, shut the lid for a few minutes, open the lid the turn on chime comes on and the screen comes back to life. The computer itself has continued to update just no screen. After a few minutes goes black again. Is logic board going bad or graphic card issue? Trying to decide if computer is worth repairing as it was made in 2007.

    It does sound like you might have a faulty video connection. See if you can make a Genius Bar appointment at your local Apple Store.

  • Event handler eats up memory. Bad programing and/or bug.

    Hello
    I've been programming a GUI for a project. The basics of the program is a sample routine that updates a array once a second. Once the array is updated I use a event handler to plot the new array in a graph.
    When I wrote this gui I think I've stumbled upon a bug in Labviews memory allocation.
    If you have two loops. One that builds a array and then signals a loop with a eventhandler that reads the array and the event handler is stoped for a few seconds (by opening a sub vi or something inside the event handler), the memory goes berserk. When the event handler is free after the stop the memory is still allocated and does not return.
    I could not find any information on this problem in the forum so I thought I would share this information with everyone. I managed to reproduce this phenomena in a small example (attached), if anyone is interested in it. The problem is simple to fix once you recognize the problem. However it was not the simplest problem to find (imho that is ).

    Where are you seeing the memory being allocated? What tool are you using, task manager or LabVIEW profiling? I'm not seeing what you describe (LV 7.1.1 on a 3.4 GHz Pentium 4 w/ 1 Gb memory)

  • G4 MDD power button going bad?

    Hi all -
    I'm using a g4 MDD dual 1gig machine. Has been working great for the past few months, till just now. When I power down, the computer won't restart, unless I unplug it. (what?) That's right, the computer works fine, I turn it off and the power button will not turn the computer on unless I physically unplug the machine for a split second. After that it powers right up (at least for now). Prior to unplugging, the power switch does nothing, no lights, no chimes, nothing. It's like there is no power going to the compuer at all.
    Does this sound like the power button is going bad or maybe something else? A few months ago I had PRAM/ PMU issues - could they be coming back?
    Any advice is much appreciated. Thanks in advance!

    I took care of my power-up issue tonight by working on my power supply. Here is the posting I made in another thread:
    Here is what I did to troubleshoot my power issue. Your power supply can be serviced and this post offers a couple thoughts and some troubleshooting suggestions. Please read it through to the end. This isn't a cure-all for all G4 Macs, but the steps I followed seem to cover a number of bases and might prove helpful to those who are really frustrated.
    I've owned a Mac every year all the way back to 1987 and have never had an issue until now and I am convinced my problem may have been triggered by a power surge or brown-out, which we seem to have experienced a lot of around here lately. This post refers to the Samsung power supply with Apple Part Number 614-0224.
    I have a G4 Dual 1.25 MDD I purchased in 2003. I have had a brief issue with powering up my CPU. It wouldn't power up last weekend. I unplugged the power cord, then reconnected it to the machine and it powered up. I reasoned the power cord had become loose, but then last night I couldn't get it to come up at all. Not even a click. No lights.
    So I tried all the easiest possible solutions: resetting the PRAM (pulling the battery from the logic board) and resetting the PMU (Power Management Unit). The switch, by the way, is located near where the ATA drives plug in to the logic board. Neither of those two things solved my problem. The CPU would still not power up.
    I checked the lithium battery voltage with a voltmeter. It was at 3.6v, so it was still good.
    I then decided my issue was probably with the power supply. With the power cord disconnected from the back of the CPU, I pulled the black power connection from the logic board and performed a power supply voltage test following the pin schematic found in this thread:
    http://docs.info.apple.com/article.html?artnum=58561
    The +5v trickle voltage found at Pin 9 was not present. I had no other voltage readings on any of the other pins. My issue HAD to be with the power supply.
    Tonight I removed the power supply by disconnecting all of the optical drives (I have two DVD burners in this unit), all of the hard drives (three) and all of the logic board connections.
    I removed all of the screws from the outer casing of the power supply, including the fat screws attaching the two black fans to the unit and the one long screw in the middle and near the edge of where the two fans are. The casing came right off.
    There have been a lot of questions as to whether there are fuses in these power supplies. There has to be some protection for them and I have yet to see any power supply that did not have a fuse or resettable circuit breaker. This power supply was no different...it has a 250W, 8A fuse that is easily accessible and is located on the same side as the male power socket, near the edge of the circuit board. It is hiding under a yellow shield and is right next to a plastic connector.
    Bingo! My fuse was blown. Many glass fuses will show some sort of blackness and mine did, as well as being able to see the actual glob of metal where the fuse burst.
    What caused a fuse to blow will be different for each machine. I believe in my case it suffered from a power surge. There were no visible signs of burns from arcing, popped capacitors, shorts or bad chips. The board was completely clean, which tells me the issue was near the power source. The fuse may also have been on the verge of popping when I unplugged and reconnected the power cord.
    Everything's speculation, but replacing the fuse did the trick in my case and I saved myself time and about $150 (on average for a used PS on eBay). I picked up a second fuse to tape to the inside of the CPU, near the power supply, so I will have a backup fuse if I need it in the future. I may also have a drive that is going bad, or I may have too many drives operating off one supply. My Mac's been configured like this for about five years now. I will replace at least two drives with new, larger capacity drives. I keep my video and digital image files on separate drives, but have a third drive I can blow out. That surely will help prolong the life of my power supply.
    While I had the computer apart I gave it a good vacuum and a little air can action. Dust can aid overheating and defeat the purpose of good airflow from fans.
    Hope this helps.

  • Is my Video Card/Display going bad??

    My display has 30-50 vertical columns, from top to bottom, across the screen. Within each column, are numerous vertical lines, like bar codes, that are pink in color. This situation happens at start up before any applications are opened. The computer(apps) works like normal, mail, safari, etc, except these lines are always in my view, on the desktop or window/page. If I "grab" a page to move it , then the whole page turns pink. If I click off of the page and then return, the page looks normal again, except for the columns of pink, vertical bars.
    Is this my display going bad or video card?? I have the ATI Radeon X850 XT video card. If it's the video card , do I replace with a new old stock (ATI Radeon X850 XT) or can I replace with a newer, better card??
    Any help GREATLY APPRECIATED!!!!! I'm Very Novice at this!!

    Hi-
    Sounds very much like a baked graphics processor.
    Have you tried cleaning the dust from the card?
    Is the fan on the card clean and rotating freely?
    If you are at all mechanically inclined, removing the fan and reapplying thermal compound is worth a try before laying out serious cash.
    As for replacement, the X850XT was the top card ever offered by Apple.
    It is also THE most rare.
    Because of this, they command high prices:

    eBay also has a number of them for similar prices.

    can I replace with a newer, better card??
    Only one option for better.
    A flashed (converted PC version) Geforce 7800GS:

    At less than half the price of the X850XT, it is worth considering:

  • Sound goes off, goes bad then effects the PC

    I'm a tumblr user and I spend most of my time there on my computer. Recently videos sounds started to go off after a few loops. Then it completely goes off or goes bad like the audio damaged terribly. Even the system slows down. When I checked other sites their sounds are bad too and even chrome or something I listen from winamp gets effected. I checked my sound settings and try to test the sound then I got an error messege saying "Failed to play test tone". It gets normal after restart.
    So I thought it's hopeless and I was even thinking of formatting my pc. But when I used chrome all day I didn't encounter this problem at all.

  • When I empty my trash, my memory goes down?

    So,
    I've just noticed this today,
    and I probably should have noticed this earlier but anyways...
    Whenever I empty my trash,
    my memory goes down?
    Is that normal?
    Because it doesn't seem right to me,
    shouldn't it increase being that I've emptied something from my computer?
    How do I go about fixing this?
    Or is it something I shouldn't be worrying about?
    Sorry for all the questions...I'm just confused...
    iBook G4   Mac OS X (10.3.9)  

    CrownJules:
    Whenever I empty my trash, my memory goes down?
    You mean your Hard Disk Drive capacity, right? Or do you mean memory as in RAM?
    Do you have FileVault turned on?
    What is the capacity of your HDD, and how much free space do you have?
    Download and runWhat Size. It will scan your HDD and list the contents by size. Look through the list for anything that looks suspicious, especially that larger files that are eating up your space.
    Take a look at this article: Where Did My Disk Space Go?.
    Do post back with further questions, comments or an update.

  • Drive going bad - Best way to save files?

    Hi,
    I've got a drive with a bad directory. I can't boot from it, but it does mount. I get a warning that it's in a special mode and that I should get all my data off of it. I have several partial backups around, but I'd like to make one good backup of everything before I start trying to change anything on the drive.
    Dragging and dropping everything via the finder into a folder on another drive didn't work. I got an error message saying some files could not be read and wouldn't be copied and I don't know which files those are.
    Suggestions, please?

    Thanks, but I'm having trouble making that work.
    It's a long story, but the only drive I have that's bigger than the drive that's going bad is the one in my Time Capsule (please don't ask why I don't have a good, recent backup on my Time Capsule. Believe me, I wish I did). I have tried using ditto to copy files to a new folder on the Time Capsule, but it is veeeeerrrrrrrrrryyyy slow.
    As a test, I tried dittoing some files to a different external drive and the job was done quickly.
    Is there some difference between the Time Capsule and another external hard drive?
    The Time Capsule is connected via Ethernet and the other external drive is connected via USB.
    I'm really confused as to why this didn't work and would appreciate any insight anyone has.
    Thanks,
    Thad

  • Allocated heap memory goes up even when there is enough free memory

    Hi,
    Our Java application's memory usage keep growing. Further analysis of the heap memory using JProbe shows that the allocated heap memory goes up even when there is enough free memory available in the heap.
    When the process started, allocated heap memory was around 50MB and the memory used was around 8MB. After few hours, the inuse memory remains at 8MB (slight increase in KBs), but the allocated memory went upto 70MB.
    We are using JVM 1.5_10. What could be the reason for heap allocation going up even when there is enough free memory available in heap?
    -Rajesh.

  • My IMac 21.5 mid 2010's HD is going bad on it, after upgrading to mavericks it slowed way down and after it shut off and now won't come back on, would Seagate Barracuda ST2000DM001 2TB Serial ATA Hard Drive - 7200RPM, 64MB, SATA 6Gb/s worked?

    My IMac 21.5 mid 2010's HD is going bad on it, after upgrading to mavericks it slowed way down and after it shut off and now won't come back on, I call apple support and they told me to bring it in but the nearest store is about two hours away. They said I need it to erase my hard drive but I have too many family pics on it.
    would Seagate Barracuda ST2000DM001 2TB Serial ATA Hard Drive - 7200RPM, 64MB, SATA 6Gb/s worked on it? I could replace the internal and get an enclosure for the original until I get the pics out of it?
    Please advise, it's like five years of family pics I don't wanna loose them and I am worried.
    Thanks

    A Brody,
    I really apprecate your very quick respond, Its too late to back up as of now, my hard drive wont load at all so I cannot follow your instruction to back it up. Learn a hard lesson but I will from now on following your link.
    Also my hard drive it is not available to do the free exchange program.
    I read the OWC instruction on how to replace the drive I was just wondering if the 2TB would work on it instead of the 1 TB they offer, I specifically asked for the Seage Barracuda because I had great experiences with it on PCs.
    Again, Thank you
