Help with unknown pc trouble

Is there anything that happened between when it was working fine and when it started acting up?

Thunderstorms, did you upgrade anything, did you physically move the computer someplace, power outages, power spikes?

Your problem could be with the power supply, motherboard or CPU. Is it overclocked? Have you ever changed any of the BIOS settings? If so, turn them all back to default.

Answer these questions and maybe you can get some help.

Cheers

hi thanks for the fast reply much appreciated man.

first the last time i remembered it was working fine was like 3 days ago my friend was using it he said he was just on facebook playing a game then it suddenly went fatal error (blue screen of death lol) then i went to sleep that night and decided to tinker it the next day. then next day as described above was the scene. I haven't upgraded anything yet its still in its condition when the first time it was assembled 5-6 years ago. i also havent moved it. well i also haven't experienced any power shortages and or spikes. by the way before that pc worked i changed it with a 500w power supply because the last time it broke like 3 weeks ago the PSU wasnt giving any power to the board so decided to buy a new one instead and worked fine until the above problem happened. yes it is overclocked by 153 since its maximum is 163. well i have 2 more identical pc's like it and the others are working fine with the said oc's. i hope i answered some of your questions man thanks in advance for sharing some info tc.
