I have built a computer that worked fine for the past two years however recently there has been an issue where it randomly locked up and had to be hard reset to come on back again. It would sometime freeze before or during POST. Sometimes before the OS finish loading properly and anytime during regular use after a successfull start.
I changed memory thinking that was the issue. The freezes went away for a day or two after this and then it returned.
Specs are :
ASUS P7h55m pro motherboard
Intel i3 CPU
Kingston Value Ram 2GB
Corsair CMPSU400cx power supply
Any Help appreciated.
From my experience freezes during POST happen when the motherboard is defective. I was unable to pinpoint my issue, i just swaped it with another model. You say it's 2 years old? I guess your warranty is up by now unless it was one of those boards with extended warranty or something.
But to be sure you could do a Memtest session to see if the RAM is causing the issue.
