I built the PC yesterday, and while using it (after Vista installation) I started getting random crashes where the screen would go a solid color (like red, blue, pink, etc.) but all the fans/components were still spinning/running.
The PSU is feeding enough energy to the video card, and I've tried tons of drivers for it. It seems to be fine. I ran a utility to check its temperature before a crash happened and it read 51 degrees Celsius with the fan running at a low speed. It's set.
However, in the BIOS my CPU temperature read 76 degrees! Not good. I opened the mobo util on my desktop and it said the temp was 60-63. And that's idling.
So is the CPU causing the crash? I've got two case fans running, but I DID smudge the silver part before applying the heatsink while building, so it could be that...however I want to be sure the CPU is responsible for the crash.
you will have to buy new thermal paste because I'm guessing you used the preapplied stuff. Make sure you clean the paste completely off the heatsink and cpu. You will need a micro fiber cloth and isopropyl alcohol. Here is a guide on how to apply the thermal paste and reinstall heatsink
Bad ass video, I been saying forever that push pins are so easy when done right, and that video proves it. Now if the manufacturers would put some directions in the box explaining to do it outside the case, so many noobs would have such a better experience.
Okay, so I wiped off the thermal paste on both the heatsink and CPU, and applied Antec Silver 5 in the shape of a rice grain on the CPU, and attached the heatsink back up. Coretemp shows idling at 40-45 degrees. Not good is it?
And it crashed as well. The artifacting on the screen is a precursor to the crashes which leads me to believe it is a video card issue. Memtest passed with no errors.
It's been my experience that the "grain of rice in the center" is not enough. I divide the heat spreader into 4 quarters and put a grain of rice sized piece of thermal paste in the center of each quarter, then carefully wipe the squeeze out away when the HSF is mounted.
