I built a system late last year and after a few days I noticed it was locking up quite regularly, usually during the middle of a download. I returned the CPU and mother board to the company, which they tested and found a fault with the motherboard so they replaced it. I got them back on saturday, re-installed everything and it has started doing it again. I did everything I could think of beforehand (i.e. testing RAM, reinstalling Windows, etc) and honestly don't know what to do now.
The only thing I can think of is that one of my RAM sticks may not be compatible with the motherboard, as it was not listed. But I assumed this was because it was much newer than the motherboard itself.
Any help would be appreciated.
