i have had alot of problems with my home build i got it in September. psu died November. got a new one plugged it in day later gpu died thats due to arrive back next week however for the last 3 days i have had 3 crashes computer just turns off and wont power up for hours then when turned on works fine till the next crash. has happend 3 times so far from hours of working to just after start up. i thought maybe the cpu was overheating used a program to check it 29-36 degrees so unlikely to be that. i dont have a second computer to check this on which kind of limits my diagnostic build is as follows! HELP!!!!
