Green distortions on screen

Yesterday when I was playing with my PC with no problems and a smooth gameplay, the game I was playing suddenly crashed and the screen halted and there appeared some green fuzz/pixels on certain craphics. I immediately force booted my computer and now it shows green blocks and stripes right from the start in bios and won't boot to windows normally. The windows logo and loading bar appears but when the desktop would show up it shuts down the keyboard and other active devices and halt's with a black screen with no CPU activity. Safe mode works, but there's still some horizontal wobbly green distortions on some textures or colours. Screen shot does not show these same distortions. What should I do? Thanks in advance!

ray:

I attached my bootlog if there's any help from it.

I have Windows 7 Pro, GeForce 8800GT display card, a8n5x mobo, AMD 3200+ CPU and NeoPower PSU.

NeoPower PSU's are low quality and low quality underpowered PSU's can easily damage other hardware. What is the Model Number of the PSU?

Sorry, my mistake. My PSU is actually Antec Neo HE 430. Too late to correct it in my original post, duh!

It's about 4 years old but the watt's don't peak even close to 430 W as I understand...

Go into bios and post your system temps and voltages

Funny, now when I booted to BIOS the green distortions were gone. After about 20 minutes idle in BIOS CPU temp is 48 Deg. Celsius and mobo temps are @ 39 Deg. Celsius. The craphics card temps do not show up there, but it was running fine at 66-87 Deg. Celsius what I recall when I observed it a while ago.

Oh, btw, I had overclocks on my system when it crashed bad time. Graphics were 600 Mhz and 900 Mhz stock and I pulled them up to 750 Mhz and 1050 Mhz and it ran just fine for a long time with temps not peaking over 90 C. The CPU was at 2.65 Ghz with 1.550 Volts and RAM, HyperTransport etc. adjusted accordingly. This was a stable setup for a long time. I immediately dropped everything to stock settings when the problem occurred.

So, now I tried to go to windows regurarly, AND it worked! No distortions anymore!

BUT I'm still too freaked out to run my system! What could've been the cause??

I even let it cool down totally for sure overnight and in the morning it did the same distortions!

My screen distorted differently a while ago but it was because of the loose DVI to VGA adapter. This time I triple-checked and pushed it while watching the screen and it was firm so it wasn't the cause.

for card temps run gpuz to get those
did you get voltages in bios? the 12v 5v and 3.3 v?

next time you re start

turn off the power on the back on the psu and back on and see if it boots normally without screen problem

Ok, the problem went away for a while and now it came back. I was watching some hq game presentation video with firefox and then the screen went black and turned on for a couple of times and windows 7 reported that my video card has encountered a problem/has stopped working/something like that and then the screen went black fr good. I restarted the computer few times and tried also to turn the psu off from the back but it won't help. Now when i turn the computer on theres flickering green blocks in the start at bios and some other green distortions also. And it wont again boot to windows. Please help me

see if you can borrow a quality 550w psu to try in it

I tried with my friend's 500 W working PSU and the problem persists.

what brand and model was the psu you borrowed

will your friend try your card in his computer to see if it artifacts

I don't know the brand and why does it even matter? The voltages in bios show up just normally, a couple millivolts lower from the exact values but that's normal isn't it?

I'm unable to borrow any video card for my system.

Now, I put my own PSU back, problem still existed, I went to bios and disabled "Quick boot" or something like where the system skips certain tests while booting and enabled restart on AC power loss. And restarted->the system went to windows normally again and no distortions. :sigh:

When I'm writing this, GPU temps show 77 C and core 45 C.

So is my videocard RAM failing? Or what else could be the cause? The videocard is just two years old and the mobo, processor and RAM are older, maybe 4 years. Is there any stresstest for my videocard that would isolate the problem to it if it's failing? It would be nice to run it now 'cause you can't do that in safemode.

After about an hour of uptime I had a BSOD while watching video from firefox:

The Furmark stability test has been running for 1 hour 39 Minutes. I took a screen of it:

It seems like the card is good? Temps peaked high and no bluescreens, crashes or any green lines. :4-dontkno

d/load the latest nvidia driver then

in the device manager uninstall the video card
reboot tapping f8 and choose low resolution mode
when windows finishes rebooting
disable a/virus
install your drivers
reboot the computer

So here's the zipped file. This was all made in safe mode as this computer won't boot to windows normally. The diagnostic tool gave an error saying 'system cannot find the file specified', so there's just the folder. Hope it gives some info. Thanks!
