Solved Screen white and system freezes

June 28, 2011 at 02:10:15
Specs: Windows 7 Professional 64-bit, AMD 3.2GHZ/8 gigs
The first time it happened was a few days ago. The computer was running but I wasn't using it when I looked over and saw that the screen had completely turned to a grey/white color. I rebooted and it was fine so I just thought it was a random hiccup. The next day it started happening over and over again. My first thought was malware so I ran Norton and a some anti malware program from Systweak. The found some spyware but nothing really out of the ordinary. I then loaded a restore point and the problem persisted so I pulled out my Windows 7 disc and ran a startup repair. I also booted in Safe Mode and the problem happened there too. At this point I thought it was a windows problem and I was all set to format when it happened when I was trying to enter Bios. This time it was a blue screen. The color of the screen seems to be related to what was displayed at the time of the crash (White, blue, grey, light brown). I was just running Memtest86 when it happened again. The system is a new build, less than six months old. Here are the specs:

AMD Phenom II X4 955 Black Edition Deneb 3.2GHz
EVGA Geforce 9600GT 512MB (Left over from last build)
G.SKILL Ripjaws Series 8GB PC3 10666
Corsair TX650W PSU
Seagate 1TB Hard Drive (also left over from old build but only a year old)

I guess I'm officially out of ideas. I'm pretty sure it's a hardware problem because it happens in and out of Windows. What's strange is how inconsistent it is. It can run for 5 hours or 5 minutes and there is no warning before the crash. No response from the keyboard and now pointer either. I would appreciate any help. I'm really hoping this is something that I can RMA for and have this fixed soon, I just need to narrow down the cause. I'm using an ancient netbook now, which is VERY undesirable for every day use. Thanks in advance

I'd try a different card or at least run diagnostics on it. If the fan is bad on the video card, it may be overheating, or has overheated to the point of damaging the display CPU (GPU).

I actually thought the same thing when I got up this morning. I pulled out the graphics card and used the on board video instead. It worked fine for a while but while I was looking online for a replacement card, the system rebooted on it's own. No screen this time, just a restart. Only this time when the splash screen appeared for Bios, it came in with wavy vertical lines. Hardboot and made it to windows loading where it did the same thing. So, now I'm onto Motherboard? Maybe the PSU?

Pop a power supply checker on when things start acting up, just to eliminate that as a problem.
I'm thinking mainboard now too. But still, it seems to be a over heat issue. Once it's warmed, it does it repeatedly. Right?
Have you watched the on board thermometer in the BIOS? Does anything appear to be overheating? It could also be the CPU; not getting enough air for heatsink or heat sink not conducting heat effeciently from CPU. RAM not cooling or timings set to high. Chipset getting hot.

You didn't crank that Deneb up to 9GHz, did ya? LOL

Though that was tempting, I opted not to overclock until I get a freezer case or move to the North Pole. I talked to Asus today and it looks like they agree about it being the motherboard. I'm RMA-ing it so hopefully it will get back to me soon and not the full thirty days they say it will take. Thanks for all your help.
