HP2000 Notebook - video scrambles and freezes,

I have a HP 2000 notebook PC, product number E0P76UA#ABA
BIOS is F.34 -05/22/2013 with 8GB total memory.
The OS is windows 7 Professional -- Version 6.1.7601 Service Pack 1 Build 7601 at the current patch and hotfix levels.
The problem that I am having that unexpectedly during use, the video scrambles to wher you can not read the screen (looks amost like the wrong frequency). this if followed by three long beeps followed by two short beeps. this audio error code is played three times and then the system locks. The ONLY WAY TO RECOVER is to push and hold the Power off button until system shutd off and then re power on. the notebook then functons normaly until it decides to repeat the problem.
Antivirus scans etc. come up with nothing.

Hi @fa4313
Welcome to the HP Support Forums.
I understand that the video on your computer seems to be scrambling and then freezing after a period of time. I am happy to assist. From what you describe there may be a hardware fault, but we can try a few things first. Since it sounds like your computer will run for a period of time, it may partly be a heat issue.
As and FYI you can take a look at this which gives a short synopsis of the normal causes of beep codes.

Assuming that it is a heat problem, then you can try this process:

If dealing with heat does not help, then the problem is most likely a board related issue, and then I would recommend calling our technical support at 800-474-6836.

Screen scrambles and freezes ipod after update

hey guys, im having some crazy problems with this ipod since the update...the screen kind of scrambles then freezes everything...is anyone else experienceing this and if so how did you fix it if you did at all...sorry if this is a repeat post but im really ****** about the whole thing...any suggestions would be most appreciated...thank you
Josh

I am having the same problem since August 2006. I tried everything everybody suggested, but to no avail. I then sent my 5G video iPod to Apple for repair. They sent it back stating "no trouble found". What a joke! If you go back to the previous version, you can't play music videos anymore, but scramble and freeze problem go away.
No point in talking to Apple tech support. They'll not understand or recognize the problem; they'll just waste your time. I hope some smart guy in this forum will eventually figure out a solution.

Quicktime video skips and freezes after exporting from FCP

I have tried exporting from Final Cut a few different ways, but my QT file had short skips and freezes in the video (the audio is perfect).
I have done this same thing several time with no problems at all. What am I doing wrong?

DETAILS
What are you exporting?
How are you exporting... QT Movie, Conversion, what settings?
What drive are you exporting to?
What version of FCP and QT?

17" MBP Occasional video flickering and freezes

Having an occasional problem with video on my 17" MBP. Processor 2.4 GHz Intel Core 2 Duo Memory 4 GB 667 MHz DDR2 SDRAM. It is a MacBookPro 3,1 according to it's hardware report and has the NVIDIA GeForce 8600M GT 256 MB video processor. When the problem happens, rectangular blocks of video begin to appear on the screen, then the keyboard freezes (won't allow input). Anybody else experienced this?

set old HD. If problem will gone - you have weakened power supply or internal power converters. Yours new HD draw more power during spinup or something - so voltage on internal bus lowers and memory or videocard freaks.
5.30 PM looks like a time when there begins a lot of load on city energy grid - so voltage in wall socket goes a bit unstable, it may also add to problem.
if problem is gone when you are on battery power - its power supply. If it persists or get worse when on battery - its internal power convertors.

24' 2.16ghz video issues and freezing w 10.5

I was running 10.5.x - I honestly forget where it was at version wise but it was fully updated as of Thursday the 25th of Feb. and I was getting many random horizontal "rainbow" lines in Safari (also updated to that day) and also the machine would totally lock up and need to be powered off via the power button and restarted. Also, I have an AOC 22" monitor on extended desktop and it would randomly dim like it was going to sleep and then wake up on it's own while I was working on it. I had a 1tb WD drive for almost 8 months and a fresh install as of Monday the 22nd of Feb so I doubt it was that but on a guess I swapped in my OEM 250gb drive with 10.4.11 on it and have had no issues since. I installed the widget for monitoring temps and my GPU temp with 10.5 was almost 62* C and running the same apps in 10.4 it is 50-51* C so maybe that is my issue? I was told to take it for repairs to an authorized Apple repair center BUT I can see this taking weeks to sort out and I have to run my whole life from this computer as I sell on Ebay and dread going back to Windows even for a short time. Anyone else experience this with this particular machine in 10.5? I was running 10.5 since I put in the 1tb drive with no issues up until then other than occasional horizontal lines in Safari, also I when it started locking up I was getting the same lines only thicker when playing a DVD as well. I do not push this machine as normally ALL I have running is Mail, Safari, Firefox and sometimes GarageSale and Iphoto but very rarely more than 3 of the above at one time. No gaming etc either.

I had this happen a few more times under 10.5 but it seems OK under 10.4 so I am wondering now if it is a hardware or software issue. I tried 10.5 fresh installs on 2 different drives and a fresh install of 10.4 on the original drive now in the machine so I do not think it is my install procedure and I did full updates on each as soon as install was done. I took a few pics and will post one to see if this looks like graphics/logic board issues or not. These were taken under 10.5, when this happened machine totally froze except cursor for the mouse was moving and visible. The only other action was spinning beach ball, had to hold the power button to shut it down and restart it. I had 3 apps open, Safari, Firefox and Mail so I was not exactly stressing the machine. This happens on BOTH the internal display as well as the external, the first pic is the external display, the rest the internal display.

Video feeds skip frames and freeze

On MLB and HBO video feeds, the video skips and freezes--this was not happening a few weeks ago--just started

1) If your camera footage was in iPhoto, and iMovie found it, it is a supported camera. It sounds like the thumbnail creation process got interrupted.
2) If these clips are not in iPhoto, but iMovie let you import them into an Event through File/Import, then they are compatible, but again, the thumbnail creation process may have been interrupted.
Assuming that 1) is true, I would recommend the following...
Go to your EVENT file under the iPhoto section of the Event list. Right click on a clip in the event, and select REVEAL IN FINDER. This will take you to your iPhoto library folder where the clip is. Copy the clip to your desktop, and change the name of the clip to something else, but leave the file extension the same. Import this changed file into iPhoto.
Close iMovie. Then reopen iMovie and let it build thumbnails for iPhoto.
Assuming that 2) is true, I would open the iMovie/iMovie Events/<event name> folder in the finder. Then I would delete the iMovie Cache and iMovie Thumbnails folders from the event, leaving the imported clips untouched. Then restart iMovie and let it build the thumbnails.

MacBook Pro display scrambles and restarts when lifted up

I have a two year old MacBook Pro (13in Mid-2012 model) running on OS X Yosemite. The device had a faulty HDD connector and it was replaced a few months back. Now if I lift the device when it is on, the display gets scrambled and freezes for a second and restarts. Also the MBP gets very hot during usage.
The MBP was purchased and used in India, but since last month after I moved to Singapore the magsafe adapter is getting very hot during usage.

Your GPU is damaged. The failing NVIDEA is very common with your model. So much so, Apple had a free replacement program until Dec 2012. Unfortunately you will need a new logic board. This will cost $750-900. I suggest purchasing a new machine.

While gaming graphics get scrambled and Satellite A200-1j0 freezes

Hi,
I have a major graphics problem with my notebook. Its a Satellite A200-1j0 with HD 2600 running vista 32bit.
When I run a game the graphics get scrambled and the nb freezes.
I have been using the nb for casual gaming since i bought it (1 year ago) with no problems.
But some days ago, a couple of games (hl2, far cry 2) started freezing my system rarely and at random times.
Today, I updated the drivers from the Toshiba site and it got worse.
It now happens in almost every game, and as soon as graphics appear after the loading screens.
Windows run without problems though.
Here are some photos of the notebook when the graphics get scrambled

http://i487.photobucket.com/albums/rr237/doomlover_gr/DSC00104.jpg

My first thought would be a faulty VGA Card, especially considering you are using the proper Toshiba Display Drivers.
I would update the BIOS and see how that goes.
Then reinstall Windows using the Recovery Disc to ensure its not a software problem (maybe DirectX is corrupted?).
Otherwise, send it to an ASP for repairs.

New 27 iMAC keeps crashing iMovie and freezing videos on YouTube & Quicktime

We just got a new Sept 2013 iMac three days ago, purchased refurbished from the Apple Store online. The whole point of the purchase was to be able to use iMovie to thoroughly edit videos for our YouTube channel, use garage band, lots of internet surfing and video watching etc. We spent the extra dollars to get what we thought was the most improved version of the iMac with all the souped up specs in order to avoid any hassle and headaches from a lack of performance. Here's what we have:
3.4GHz quad-core Intel Core i7
27-inch (diagonal) LED-backlit display with IPS technology; 2560-by-1440 resolution
8GB (two 4GB) of 1600MHz DDR3 SDRAM
1TB hard drive (We have only used 80 GBs of it so far, so plenty of space left)
NVIDIA GeForce GTX 775M graphics processor with 2GB of GDDR5 memory
720p Camera & Mic
OS X 10.9
We're feeling a bit duped now as this seems to have turned out to just be a big expensive piece of junk. Here are our problems:
- Firstly, thank goodness that we had our own Logitech HD camera/mic left over from our PC because the "HD camera" built in to the iMac is worse in quality than my old blackberry curve. Grainy, lack luster, mic has sharp and distant sound, really really bad and false advertisement.
- In the middle of using iMovie (iMac came preinstalled with the newest one, i think its 10?), it will stop responding properly or will crash and close, we wont even have any other programs running.
- When opening Quicktime to record a new video, in the middle of a recording or while the recording window is idle, it will start glitching - flashing between live footage and a freeze frame repeatedly. The only way to stop it is to quit out Quicktime and open again and try to record quickly, or in some cases we have to completely restart the iMac, which then still randomly in the middle of a recording or idle window it will continue to flash and glitch. (You can view an example here in the last minute of one of our videos, we tried to make it work and kept the take since we were doing our outro music dance, but it totally ***** when this happens randomly during our content portion and we have to redo recording. http://youtu.be/MAJzaEShJGw?t=4m34s )
- When watching YouTube videos, the computer takes a while to respond to a command, like if we click on a certain part of the video, it will not load it until we press the pause/play button a few times and wait. Also at the beginning of a video it will start glitching and freezing again, similar to how we explained above in the quicktime, but faster.
If you are familiar with what could be the problem or have any advice, PLEASE HELP, we are concerned that after dropping so much money within just 3 days of use, this iMac is not performing flawlessly in the areas that we most needed and want to know if these issues are common and fixable or if its a defect that would require we send this thing back immediately. We did not get apple care and would hate to have wasted money that we really dont have on a glitchy crashing huge piece of junk.
Want to mention a few other pros and cons unrelated to our issues, for those who may be considering buying one too:
PROS:
- The Magic mouse is really great, particularly because of the scrolling and zooming gestures. (Though sometimes i accidentaly swipe in a browser and go back to a previous page losing any information that was input on the page i was originally on, for example, i had to retype this whole apple imac inquiry because i swiped backwards by mistake and the whole form cleared! annoying, wish the horizontal swipe navigated between tabs instead of going through the page view history.)
- When the imovie is not crashing, after watching some tutorials and making a few vids, its a really greatly improved program from the '09 version we used to use. I import and edit videos much faster now, and footage does not freeze or take time to load while im dragging and dropping, it is immediately responsive.
- Love using the Talk to text function (like Siri) by pressing "fn" twice. Use this to write long emails and papers with ease. Would like to see a "Speak" read back option that allows for text to be selected and read back (like Siri on iPad)
CONS:
- The text is SO small everywhere and there is no option to exactly set text size across the whole system, only option given is to set a different resolution which lessens the quality of the screen with pixelation, and some programs give you the option to set custom sized text in their individual preferences.
- Sometimes in both iMovie & Garageband, simple automated functionality will stop working, for example in iMove, when certain screens or images are dragged and dropped to the work area by the activity bar (i dont know what else to call it, the line that rolls across during playback or stays put when pressing spacebar) usually, that screen or image will click into place to align with the activity bar and will highlight the bar yellow to further communicate that alignment before you drop it, but after extended use in a session, that snapping into alignment when adding items stops working. Or sometimes you can drag and drop the ends of a title screen to adjust/trim the clip, but after extended time that too stops responding and does not let the cursor turn into that arrow that allows you to trim or extend, until after many frustrated clicks or a quit and restart.
- When sharing/exporting a video from iMovie, i would recommend unchecking the add to theatre option because it significantly extends the amount of time needed to complete the action and i found out the theatre is just like a video stream of your movies to be shared on icloud for easy access from your other devices (similar to the icloud photostream connected to iPhoto). It takes the time to make the video readily availabe in various sizes on the Mac server for easy access, which means it takes forever for your video to be exported to where you actually want it. This is not something we need and is not worth the wait time. (For example, last ime we left the theatre box checked, the progress status of the video was estimated to be completed in 351 minutes, and then 20 minutes later that somehow inclreased to 385 minutes, then duddenly it was done, so i think this add to theatre option also cause the progress status updates to go berzerk.)

Given the maximum RAM that model can use is 32GB, and the earlier release of that 27" mid-2013 iMac is nearly the same in most regards, you may note the listing of this slightly older iMac 27" is here in an Apple support document...
•iMac: How to remove or install memory:
http://support.apple.com/kb/HT1423
http://support.apple.com/kb/HT1423#1
The images of where the RAM chips are located, behind a metal plate, should be similar in your iMac and the mid-2013 iMac 27" shown in images on that page. Note there are several models discussed.
You could take the computer to a certified Apple service facility (retail store, or specialist reseller) and pay them to do this, and buy the RAM from them, and you will pay for this at a retail level. If they do it, you'd want to be assured the computer did all the things you sought to cure by upgrading RAM, correctly without fault. Like run tests and stuff.... Or there's no reason to not go ahead (after confirming from Apple) that you could buy quality RAM and do this job yourself, citing the Apple page link I'd posted above.
Contact Apple Support:
http://www.apple.com/support/contact/
You'd have to obtain the correct RAM (as indicated in my earlier post, citing MacTracker) of suitable quality for use in a Macintosh computer, and the recommendation for a DIY is to get the kit from 'Other World Computing' OWC online at their site. You can talk to knowledgable sales staff at OWC about what you have and what you need, and to help they may ask for the product serial number.
This is OWC and they have the spec RAM required for your iMac 27" model; double-check info:
http://eshop.macsales.com/shop/memory/iMac/2012_27/DDR3L
Since yours is an Apple Refurbished model it will have a different number series. Unlike those in a retail store, because Apple does that to tell what ones they refurbished; refurbs I bought online were like that.
With questions during the first three months, you can get 'support' under the initial 90-day span of ownership of the new (and certified) Apple refurbs bought online; the other part of that is 'service' for 1 year. Call a nearest retail Apple Store, to set a genius appointment; or go online, and start the process of reporting your issue, while you still have some kind of warranty on the device. They can diagnose the issues you cite and tell you if you can upgrade the RAM (as you likely can) then you can buy and install the RAM yourself and probably pay less than 1/2 the retail rate, if you get some from OWC. A diagnosis is free if the Genius looks into it, but you'd need to set an appointment & lug the iMac to their store; protected from weather/shock.
If you want to extend the complementary service to three years (less the included 90-days) and add two years of AppleCare service, that is an affordable option of about $170. For a total of three years coverage.
{If you had a 21.5-inch iMac the RAM would require a service department visit where they use a different method to install the RAM upgrade. Those are built differently than the 27-inch iMac.}
There is a bit of detailed important information in the Apple link on how to upgrade the iMac RAM. There is a certain amount of RAM installed already and these chips would likely be removed if you get matching sets of new RAM to upgrade the capacity. And no matter what some say, there is a reason why they can be upgraded with more. Even with Mavericks OS X 10.9.x and its 'memory compression' etc, it would gladly accept all the RAM upgrade chips it could swallow. (Behind metal screen, mid-bottom iMac 27")
You may need to consider questions about applications that use system resources separate from those about whatever issues your iMac seems to exhibit. There may be some other cause of the video and iMovie symptoms, but more RAM won't hurt given the beast you bought can use 32GB and it has 8.
And if it seems too much to handle, you have 14 days from date of
purchase to take it back. Contact them ahead of then, if you do.
Hopefully this helps.
Good luck & happy computing!

Just done a fresh install of Snow Leopard with all updates,iMac 5.1 behaves strange, sometimes I start Google Chrome and look at youtube videos the computer freezes and shuts down immediately, I believe its related to overheating ?

Just done a replacement of the pata DVD drive (its new and is working ok), and a fresh clean install of Snow Leopard with all updates, iMac 5.1 behaves strange, sometimes I start Google Chrome and look at youtube videos the computer freezes and shuts down immediately,
I believe its related to overheating ?
iStat Pro shows GPU diode temp at 66 C, CPU at 48 C, Fan rpms is around 1000
Any ideas somebody ?
The hard disk has been previously checked with state of the art techniques that have confirmed that the hard disk drive is in perfect condition.

I have restored this

TimeMachine is only a backup and restore, it won't fix issues in software and according to your information, doesn't even optimize the restore for best performance on boot hard drives.
What you need to do to regain your speed is to understand how your machine works
Why is my computer slow?
Fix any and all issues in software following this list of fixes

Most commonly used backup methods
There shouldn't be need to reinstall OS X fresh unless your having file structure issues which if they are should appear when in the Steps, which then a zero erase and install will cure as well as any bad sector issues, the defrag step wouldn't be necessarry on a freshly installed system obviously as the files are written all together, not in portions all over the drive.
Hope this assists.

When i'm watching a show or movie on iTunes, the video will randomly freeze and the audio will continue, the video catches up after awhile, but it does it again. This happens to all my shows, and I downloaded them from iTunes. Why is this happening?

Whenever I try to watch movies on iTunes on my computer, the video will randomly freeze, but the audio will continue. This happens will all of my shows, however this never happens on my iPod or iPad. Whenever I want to watch a new movie I buy or any of my shows this problem keeps happening. I have tried uninstalling and reinstalling and it did not work. Why does this problem keep happening, and how can I fix it? Thank you.

John0618. Did you ever get a response or solution to problem? I have the same problem (starting about three months ago).

What is the best Apple notebook for video editing and pro music creation?

What is the best Apple notebook for video editing and pro music creation?
I know I could opt for the most expensive and probably get what I want that way, but I´m not made of money, so what are your suggestions for minimum criteria and which would you recommend?

MacBooks Pro are great Macs with a good hardware, so all of them will work for the use you want, but I think that you want the biggest display possible because of your uses. In this case, it has to be a 15-inch non-Retina MacBook Pro, with the settings you want. Note that, after buying the Mac, you can upgrade the HDD and memory without voiding the warranty, so you are free to install as much memory and the HDD size you want after buying it. It's my opinion, but you are free to do whatever you think it's better
