Yesterday, I was playing AOE 3 and the video started to get really scrambled. The game closed itself a few mins later and it was still scrambled at the desktop. The Windows 7 task bar really discolored too. I preformed a restart and it was still scrambled on the shutdown screen. When it restarted it started like normal. It said Windows is loading files. Then it restarted itself again. Again it started normal. Then it said something about the file seeming to be corrupt and the checksum wasn't the same as the computed checksum. I preformed a hard reboot then noting happens. The power light comes on but there is nothing on the display. No beeps ethiter. I did get it to boot once and it got to the start up repair screen. I selected start windows normally but after a few seconds it restarted itself. Then it did nothing again. What happened? Did the gpu burn out or did the motherboard die?

You can test this out as next, when you have an integrated gpu:

Take care that in the Bios menu, the gpu setting is on the integrated setting.
Close your computer and after this, remove your gpu card.
Than start you the computer with the integrated gpu.
When the computer works fine, than do you know that it is not the Motherboard, but your external gpu.

It could be the graphics card overheating if there is one.

I don't have a graphics card, I used the intergraded 9200 graphics. Toady after resting for over 12 hours it booted up fine. It worked fine for about 20 mins. Then video started to get scrambled (not nearly as bad as yesterday) and about 30 secs later it blue screened with this error: "A process or thread crucial to system operation has unexpectedly exited or been terminated" when it rebooted I chose start windows normally then after the welcome screen the screen went black and about 20 secs later I get another blue screen with this error: apc_index_mismatch. After it restarted it was back to doing nothing. Also, the computer automatically turns on when I turn on the power strip of that has anything to do with it. It never has before.

Are we dealing with a laptop (9200m) or a desktop (9200)?

Desktop- verify the heatsink on the northbridge is clean. If it has a fan, verify it works. GPU-Z should tell you the temp (not sure on that particular GPU) Download link at bottom of page- http://www.techpowerup.com/gpuz/ While you have the cover off, check all of your capacitors for bulges. Use a DVOM and check the 12V on a spare molex (4 pin connector, yellow to black) while the system misbehaves.

Lappy- 9200M might be lumped in with the defective NVidia GPUs (mostly 7XXX and 8XXX) I know some of the 9XXX series were defective, but not the specific chips. Also verify the chips temp as well. Hook the lappy up to an external monitor or TV to see if they also screw up. If the laptop screen is messed up, while the TV/monitor is OK, you have a bad internal connection somewhere.

Its a desktop. I saw no bulges. The GPU keeps getting progressively hotter for no reason. Its just idling at the desktop. It started at 60.0 C and it peaked at 76.0 C.

Anytime I start seeing anything on the screen scrambled, or oddball colors, my suspicion is the GPU (or sometimes the connector if it is VGA). 76C is high for idle, 85C is upper limit for normal use in games, 100C is the limit before damage occurs.

Did you check your voltages?

I don't know how much effort you want to put into salvaging this motherboard if it is faulty. Easiest solution is grabbing another videocard (assuming you have an open slot) and going that route. You might pull off the northbridge heatsink, clean off the thermal compound/pad and reapply some quality thermal compound and see if there is any difference. You usually have to pull the motherboartd out of the case to get the clips off the sink though.

The "Bumpgate" fiasco. http://semiaccurate.com/2010/07/11/why-nvidias-chips-are-defective/ Many enthusiasts bake/use a heat gun to reflow the solder bumps on the GPU which crack on some models of NVidia GPUs. I feel better about baking a videocard rather than a motherboard usually.

I think it is virus related. It seems to happen whenever I'm doing anything related to running virus software the screen scrambles and the computer throws a random blue screen. It happened shortly after I ran spybot and while I was updating malewarebytes and avg. It wont boot into safe mode, it just restarts itself after it loads files. Im probably gonna have to do a recovery again. However this doesn't explain why the gpu gets hotter and why it turns on as soon as the power strip is turned on. It don't own a DVOM nor do I know how to use one so I didn't check the voltages.
