G4Ti4200-TD Flickering

After 10 minutes off gaming my screen begins flickering. The screen switches between game and black screen really fast. And it becomes totally unplayable. This happens in any 3D-Game.
I have tried almost everything:
new and older gfx-card drivers
new gfx-card bios
new mainboard bios
new directx
all updates on windows update
anti-virus
anti-spyware
a total re-install
one extra 80mm Case Fan
a new monitor
Mainboard and CPU temperatures is only about 40 degrees celsius while gaming.
decreasing gfx resolution and -detail is the only thing that does work, but it doesn't solve the problem fully.
only obvious "issue" is that +3.3Volt only is about 2.8V (measured with ASUS PC Probe). I don't have a clue, if this has any impact on gfx-performance.
IS THIS A HARDWARE ISSUE? OR?
MY SYSTEM SPECS:

i have tried changing my monitor, but i didn't help.
At first i thought it was a temperature issue. But i think that i maybe could be a power issue. If this is the case, what are the recommended psu specs for my system?
Could somebody confirm/reject this?

Apple Mini DisplayPort to VGA Adapter flickers

I have 2 Samsung SyncMaster 23 in, HD Displays connected to my Mac Mini. The Display connected via the Mini DP to VGA adapter flickers erratically. This started happening after installing the latest upgrade of OSX Mountain Lion. I called Apple support, they gave me a list of steps to try to fix the problem, which I followed to the letter, to no avail. The problem is annoying, to say the least. I tried to find out if there was a firmware update for the adapter, but I am running the latest firmware (1.03).
I would appreciate any help to solve this issue.

Thank you for your message.
1. Both monitors only have VGA input.
2. The other adapter, Mini-DVI to VGA has always worked properly.
3. The Mini DisplayPort to VGA adapter is an Apple original product I bought at an Apple store. I bought 2 adapters.
4. Actually I have 2 Mini DisplayPort to VGA adapters: The one I use with my Mac Mini, and another adapter I use to connect my Mac Book Pro to a Panasonic projector.
5. I have tried using both adapters, and the flickering problem is present using either adapter.
6. I believe the flickering problem is definitely something that needs to be addressed and solved by Apple. The adapter is its product, and should work as advertised, no matter what version of OSX I am running. Please remember that there was no flickering before I upgraded to the latest OSX Mountain Lion.
7. I do not believe buying an adapter from another manufacturer, as you suggest, would solve the problem.
Thank you for your help.

I have a brand new MacBook Air 11 inch, 4gb RAM and 256 gb SSD where the screen flickered abnormally and got dead all of a sudden while uploading a photograph in FB. Can anybody help?

I have a new MacBook Air 11 inch, 4gb RAM, 256 SSD and use Mavericks OS. It is still under waranty period.
Just few days ago while I was uploading a photograph in facebook, the screen started flickering abnoromally. I tried using the escape button but nothing was working so switched off by pressing the power button.
After few minutes I tried to switch it on but my system never waked up. Called up the Apple Support, did SMC and PRAM but nothing worked. Then I was advised to take it to Apple's authorised service centre.
At the service centre the engineers diagnoised and then said that the MLB/mother board needs to be replaced. Had waited for six-long days and today they had replaced the MLB/mother board. Now, the system came to life but nothing has booted. The screen goes white and a '?' question mark icon keeps on flickering.
After thoroughly diagnoising it the engineer said that now the problem is with the SSD and the worse thing is all my important documents and photographs etc are no more there. And I don't have a backup of the same!
While Apple Support contact centre is assuring they would replace any other parts if found faulty, but I feel differently. First, the MLB/mother board was changed now they say it is SSD problem - so if the SSD too is replaced there are possibilities of more faults coming up. All I can see and feel that this particular machine has turned out to be architectually deffective that calls for immediate replacement.
Right now I am using a friend's windows pc to write this mail.
Feeling completely miserable - all my expectatations gone after investing in such an expensive machine, loss of all my data, wastage of time and energy and to top it all affecting my daily work.
Can anybody please advise what shall I do?

Take the system to an Apple store to be fixed or replaced as the one you have has defective hardware.

Hard Drive Is Flickering:

I have been podcasting...downloading lots of the free ones... and some of them are a few megabytes but some are 1/2 of a gigabite. This takes up space, and also OS X And OS 9 on the same 10gb hard drive. There is 1.5 gb left.
My 80gb samsung hard drive connected to USB, keeps getting "Device Removal" again, and I opened Disk Utility and it said something like "It is a 1 and it should be 0." and it did not repair it. }=[ It still mounted it, and it has all the files and nothing appears to be damaged or missing, but it kept not-ejecting the hard drive. It began when I transfered a large podcast file onto the external hard drive and Finder hung on the transfer. Finder itself did not freeze up, it was simply not finishing the transfer file. I forced quit Finder and it would not come back up. I went into Terminal and typed
/System/Library/CoreServices/Finder.app/Contents/MacOS/./Finder
and it came up. and it froze and then I typed killall finder and closed out of Terminal and re-opened it. Finder launched by itself this time with no problems... but I ran disk utility and my disk is messed up. That's it. I am going to connect the large hard drives to OS 9 only, and to transfer files off of OS X, I will use SD Cards with a USB adapter.
And in a few weeks I will buy fire wire enclosures. I hope very much that the fire wire won't have the same issues that USB has. It is plugged into USB hub now. The hub is self powered...and plugged into its own power strip. I know I shouldn't use USB hubs, but it can be difficult to have the hard drives plugged in, sync-ing an ipod, etc. all at the same time, and it annoying to have to unmount and disconnect routinely. Also...all my mp3s are stored on the external drive...so that is one reason why I had the ipod connected to the imac, and a hub connected to the imac with everything else (keyboard, mouse, and one of the USB enclosures) so I could easily have mp3s on my ipod.
But the only thing I did when it hung was transferring one (very large) podcast from internal hard drive to external hard drive.
Anyways, I have more "Computer Trauma" and do not ever want to connect external hard drives while running OS X. even with fire wire.
Also I am not going to bother moving files off of damaged directory hard drives with USB. I hope Fire Wire will be MUCH faster.
===========
And This Is Where I Am Now:
I connected USB enclosure with the 80gb Samsung directly to an imac with OS 9 booted and I turned on the enclusurer. The volume mounted instantly. Files could be accessed instantly. I also transferred some files on it to see if it would let me or if it would display an error message. It let me put files on it.
But........
Why was it flickering for like 10 minutes???????????????
The light was flickering from green to red a lot.
Is this "Mount Check" ?????????????
I thought Mount Check turned the arrow into a watch and the clock froze until the volume could be mounted. But the volume mounted, nothing froze, but the mouse arrow was slow and choppy for a while. It has stopped flickering. The light on the enclosure is green. What was OS 9 doing?????? Mount Check????? Defragmenting????? Repairing a directory?????? =S
Also.........sometimes when I had it connected it to OS X, OS X was doing something to my hard drive. =S I don't know what, but I wanted to eject the drive and it wouldn't let me!!!!!!! }=S I did not have any applications open such as iTunes, which could have been Using the hard drive. =S
And..... since I have discarded my 120gb maxtor, and the 20gb Western Digital and a 20gb Maxtor got zapped by that Blue And White power mac g3. ... I am using a damaged 80gb seagate.
I connected it. Nothing was on it anymore. But I connected it to OS 9. I erased it, because it said "the disk could not be read". It formatted it as
40gb!!!!!!!!!
And. every time I mount it, It says "...disk could not be read...", and if I select, "Eject"...
It mounts!!!!!!!!! =S
I can store files on it. I am not going to attempt to connect it to OS X. But OS 9 mounts it, even when it is damaged.
I appreciate lots of advice.
What I have:
= 80gb samsung with a 1 that should be a 0.
= 80gb seagate with damage but os 9 formatted it as 40gb and if I select eject on the error message, it mounts it instead.
= 2 imacs. One with a os 9 startup volume, and one with a OS X startup volume. Both with OS 9 drivers. imac g3s.
= 2 USB enclosures. But I am going to get Fire Wire. and some large drives. (should I get SATA, or 2.5 inch... or do these cost more????????? )
= AC adapter USB hubs... 7 port, with LED, and connected to its own power strip. The enclosures also have their own power strips. No, the power strips are not plugged into each other.

I appreciate any advice that people have.
It is possible that one of my enclosures has faulty power...something could be loose. An error message occured once while transferring files with OS 9.
I am still going to use OS 9 to move files and organize files that are in external storage because in my experiences, OS 9 is less likely to cause directory damage in the event of some power failure.

What's wrong with my MacBook? It's flickering and beeps.

I bought my MacBook Pro 13" in October 2012. It worked fine and then on December 25 I was using it and a rainbow on vertical stripes started flickering and took over the screen so I had to hold down the power button and shut it down. I took it to the Genius Bar and she did nothing for me. About a month ago the screen started to flicker and was completely distorted. I took it in and they sent it to Austin where they reset the RAM. I got it back and yesterday I pressed the power button and the screen stayed black and it beeped three times then paused, beeped three times, paused, and continued in this pattern. And later last night I tried to turn it on again and it turned on but after about five minutes it flickered and the screen was completely distorted. So I forced shut down. The same thing happened again this morning with it working for about 5 minutes then distorting. This is annoying because I've taken it in twice and it continuously have the same problem. The only thing I have downloaded is Google Chrome. Before they sent it in and reset the RAM and to factory version I had Sims 3 on it but when I got it back Sims 3 wasn't on it because I was reset to factory settings, so Sims couldn't be causing it.

G4Ti4200-VTD64 voltage incompatibility with MSI K7N2 Delta-ILSR??

Hello,
I have the MSI G4Ti4200-VTD64 (4X) video card.. I want to upgrade my motherboard to K7N2 Delta-ILSR. Is there any voltage incompatibility?? I heard that new mother boards will support only AGP 1.5V. Is the AGP voltage of K7N2 Delta-ILSR 1.5volts?? Is my video card compatible with this voltage?? I really want to retain my current video card as I am quite satisfied with it and I'm not willing to invest on a new one at the moment. If there is an incompatibility could you suggest another Socket A MB with good performance and SATA RAID support.
Thanks in advance
Regards,
Joseph

Satellite U400 - Display flickers when idle

As mentioned, I've this problem of flickering whenever I don't run the screensaver! My machine is still under warranty and this problem has been persisting 3 months from now. Please tell me if any configuration or any measures to be taken...
Thanks in advance and regards,
Sanjeev Gopinath V

Hi
Can you please test an external monitor on your notebook? So you can determine if the problem persists only on the internal monitor or external monitor too.
But before you go to an ASP you should make sure that you are using the newest display driver from the Toshiba website. Check this:
http://eu.computers.toshiba-europe.com => Support & Downloads => Download Drivers
If you have the flickering on the internal monitor I think you will need professional help from an authorized service provider. The technicians can check your notebook and if your notebook is under warranty the repair should be for free.

Display Error - weird black/blue flickering boxes on display

I have recently started experiencing a very strange error with my iMac G5 display. I notice it most when using Expose. As the screens zoom in and out, several black or blue boxes can be seen flickering in the background. Each box is square and approximately 2 inches x 2 inches.
Also, if I scroll my mouse across the icons in my dock, suddenly a large, very zoomed in version of my dock is superimposed over the actual dock. Sometimes random black boxes appear behind an icon in the dock too.
If I activate expose, the boxes or zoomed in dock disappear. Also if I scroll up and down a page, the boxes vanish but can sometimes reappear later.
It started a few days ago, but then went completely by itself. It's just started up again tonight. I haven't changed anything on my computer or downloaded anything that might have caused this issue.
I'm not sure if it's a hardware thing or something wrong with my settings. Any help would be gratefully appreciated.

I have already checked those and neither are activated.
Also, if there is an animated gif, or something that moves, the entire display is filled with a horizontal line that's the same colour and height as the gif. If I refresh the screen or activate expose, it vanishes, but then comes back pretty soon after,
It's funny because I've had it on most of today (after being shut down all night) and it's been fine. It's just started again this evening. Makes me think something could be overheating perhaps.
Thanks for trying to help anyway.

Problems with ATI Radeon HD 2600, electrical interference or flickering pix

Problems with ATI Radeon HD 2600, electrical interference or flickering pixels
I have a Macro 8 core purchased just 4 months ago with the ATI Radeon HD 2600. Just started getting what looks like electrical interference or flickering pixels all over the screen. It gets worse and worse to the point where i see and cant work then clears up for an hour and then comes back.
If I change the resolution from 1680x1050 to 1600x1200 everything looks fine and the problem goes away.
Monitor works fine on two other computers, driver is up to date.
Would like to upgrade at some point just disappointed that I’m already having problems.
Any suggestions would be very helpful, in the mean time I’ll searching the forums.
Thanks,

Photoshop CC flickering on Macbook Pro?

Hey guys.
So I got a new Macbook Pro less than a month ago, mostly for drawing and such. I've encountered a problem, though, and that is that when I use Photoshop CC, the screen flickers! Not the entire screen, but the window in photoshop. This seems to only happen if I'm using my tablet, as well.
I spoke to Apple several times about this issue but they told me that there was nothing they could do and that I should speak to Adobe. They just linked me to some updates that didn't work and that was that.
I've seen many, many, MANY people having this issue on the Macbook Air, but they have a fix now. I haven't seen so many people with the Pros having this problem, but there are a few, such as here:
http://forums.adobe.com/message/5955871
Sometimes it doesn't flicker, but most of the time it does. I've updated everything that I could think of. This is causing a real problem though; it's nearly impossible to work on any project at all anymore!

This is happening on my end as well. Moving text, painting, etc. causes the display to flicker. I tried diffrent Graphics Processor Settings in the preferences, but did not notice any improvement.
Adobe, please fix this bug!

Yoga 2 Pro WONT TURN ON (backlight flickers)

First time poster here,
I recently purchased a yoga 2 pro approximately one week ago in Hong Kong from a technology reseller (Fortress). Was super excited, majority of reviews were glowing etc. However, after taking home and using it for less than an hour, the whole computer just suddenly turned off. All i had done was install AVG anti-virus, real player, and Hearthstone (blizzard game, didnt play it yet). When i tried to turn it on again the power button and backlight keyboard would flicker every 5 seconds, but no screen came on. I tried with/without being plugged in to no avail. I wrote this off as bad luck and swapped it the next day for a new one.
New one worked great for about 4 days, when the screen suddenly went haywire going all fuzzy with heaps of static (like one of those really old TVs when u get bad antenna reception). It was not responding to any keyboard or touchscreen commands, so I hard reset it (held power button for about 10 seconds). When i attempted to turn it back on again, same thing happend as the first laptop, flickering every 5 seconds, no screen. I will add that for these 4 days it worked I had mainly used it to watch youtube, play hearthstone, and watch movies. No other issues came up before the sudden breakdown. However I also noticed that when I played Hearthstone (a very low graphic intensity game btw) the laptop base got very very hot. I had also set my energy manager settings to high performance mode (part of the 'fix' for the off yellow colour).
I've now swapped it back for a THIRD yoga 2 pro. The salesman said this was the last time they would swap and if it happened again we'd have to go through Lenovo.
I've had it for a few hours and it seems to be running fine but i wanted to post up this experience up to see if others have had similar issues, or might know what might have caused two of these beautiful laptops to cease working. The salesman suggested one possibility as being the laptop overheating to the point that it damaged the hardware in some way, although I would have thought that most laptops would have sufficient protocols to prevent damage to the laptop in this way. Any other suggestions or tips would be appreciated.
Sorry for the TLR

I have the exact same problem. It first happend within one hour of opening the box. However, the problem went away...returned intermitently...and now my yoga 2 has a totally dark screen and flikcering keyboard. I was previously a big proponent of the machine. Now, i'm thoroughly disappointed. Customer service does not seem to have any answers.

13.3" macbook pro flickering screen when waking from sleep

I have a Mid 2012 13.3" MacBook Pro (non-Retina) laptop that has been working well, until the last few days. The laptop has had no physical damage and no liquid damage. I have put the laptop to sleep by closing the lid. When the laptop lid is raised and the laptop turns on this last week I have noticed that the screen flickers and then appears to be on, but the screen is a grey color. I have been able to press the power button to put the computer back to sleep. Usually when pressing the power button to wake it from sleep the screen issues have cleared up.
Is there a known issue that may cause the issue with the flickering/grey screen or could there be a short in the wiring that powers the screen?

Hey there Oregan Mac User,
It sounds like you are getting screen flickers when trying to wake your device from sleep. I recommend the troubleshooting form the article named:
Apple computers: Troubleshooting issues with video on internal or external displays
http://support.apple.com/kb/ht1573
Reset the system
You can reset the Mac's parameter RAM and SMC.
Reset the resolution
Start by resetting the Mac's parameter RAM. If the display does not come up, was previously set to an unsupported resolution, and still results in no video:
