Computer White Screen Crashing
My computer has been exhibiting an odd issue that has recently become a problem in more than one game. My system will load and start playing games fine for while and at some point the screen will just got white. Sound will persist for a few seconds and either stop or stall on a small segment of a sound. Sometimes it crashes to a black screen, but maybe 1 in 10 times only. It usually take 30 seconds to a minute and then will write to the hard drive and then reboot.
At first it only happened in Driver: San Fransico some time late last year when I picked that game up. Then during the summer sale I was gifted a copy of Grid, and that game started, but would quickly crash. Got through one race, crashed and restarted and crashed while in the video settings menu.
Last week, the problem showed up in Firefall. Whenever I got into a high intensity situation, some after more than 15 minutes of other stuff, but sometimes after just a couple minutes, the system would crash. Always during the same event type and I'm almost certain it was when things started getting hectic on screen.
Throughout, I've been running ATI Tray Tools (to manage fan speed) and GPU temps via the OSD have remained below 90, and typically between 80 & 85.
CPU Temps are good, maybe getting into the high 40's or low 50's.
Some more history: Last year my computer was impacted by a storm. The damaged seemed to be limited to networking stuff. It took out the ethernet ports on the cable modem, router, and computers that were connected. The unconnected ethernet ports and wireless on the router still seemed to work. But my onboard ethernet was fried on this computer, so I replaced it with a dedicated card and disabled it in Windows and BIOS. I haven't seen too much else odd aside from the death of a 6 year old HDD in January of this year. Otherwise, the system has been stable.
The only thing I can find via google that worked is one person with an Nvidia card at one point had to roll back his drivers. I don't think I found much of a solution otherwise, just a LOT of speculation and no reports back of success.
I do not have extra components to test power, mobo or video card with. The only other desktop in the house uses an AGP vid card and was built in 2004.
Any help is appreciated. I guess I could try rolling back drivers to before they put the 4000 series on legacy support.
