Windows 7: Random Computer Freezes, No BSOD Error

Hello Everyone!

I've been getting some random freezes with no BSOD error since I put my computer together. I've already been told by several others to replace my power supply, which is exactly what I did. However, I have a feeling it's something else.

Here's exact build:

Windows 7 Ultimate

I've already checked all my connections, re-seated all of my components, and made sure to blow out any dust or debris with some compressed air.

I also ran sfc /scannow, and there are no errors reported.

What do I do now?

I found the solution.

My motherboard automatically set the memory timing to 9-9-9-24. The spec on the RAM I bought calls for a 7-7-7-24 timing, so I went into BIOS and changed it to that.

So far, no problems, especially after a 4-hour Prime95 stress test.

Case closed.

Awesome! Nice work!!

Thanks for posting back your solution to hopefully help others with similar problems.
