BleepingComputer.com: Computer crashing (Possible video card failure?)

Howdy,
This problem has occurring off and on for the past several months. Anytime any game or video (sometimes audio only) is played the screen starts artifacting (sp?), turning pink and then crashes. It will sometimes take up to 7 or 8 tries to get it rebooted. Someone had mentioned it could be a heating problem, so I ran Speedfan and saw that my temps were extremely high. I popped open the case on my computer, saw the fan that was attached to my motherboard was not working, replaced it (the fan) and cleaned the whole computer out. It ran great for a 4 or 5 days and then the problem started again.

I have tried to contact Microsoft support but they are awful when it comes to helping with anything. I tried to launch a startup repair, but this was the message I received:




Startup Repair diagnosis and repair log.
Last successful boot time: 8/2/2010 7:04:42 pm
Number of repair attempts: 2

Session details:
System disk = \Device\Harddisk0
Windows directory = C:\Windows
AutoChk Run = 0
Number of root causes = 1

Root cause found:
Unspecified changes to system configuration might have caused the problem.
Repair action: System files integrity check and repair
Result: failed. Error code = 0x490
Time taken = 786588 ms




The thing is, I cannot think of any changes I may have done that would have messed with the system configuration. I have owned a PC for a little over a year so am still fairly new to this, but if anyone at all could point me in the right direction it would be greatly appreciated. Oops, almost forgot, this is my system I am running:

HP Pavilion Media Center m8430f PC
Intel Core 2 Quad Processor Q6600
4096MB
750 GB
Wireless LAN 802.11b/g
NVIDIA GeForce 8500 GT
Windows Vista Home Premium 64-bit edition

I hope I provided enough info here, once again thanks to anyone that can help me out.

Welcome aboard

Possibly, some damage was done to your CPU while it was overheating.
IMHO, the quickest way to find out would be a clean Vista installation.

I was worried it might be something like that. I'll definetely have to tackle that tomorrow. Thank you

Keep us posted
