PC Shuts Off Randomly

If its still turning off randomly, try cleaning the dust from the power supply and the cpu fan, i have encountered this problem many times

 

Have you replaced the power supply yet? I still think that's the most likely cause.

 

Yeah, I had a thread about this, God knows where it went..

After replacing the RAM, Power Supply, all that sh*t, still nothing. Unplugging everything one by one by one it's all still quite fail. i can't even use my iTunes, or play GTA lol

any more suggestions are appreciated.

 

Are you sure all the connections are correct after having replaced the power supply? Did you remember the 4-pin CPU power connector?

 

Yeah, all my connectors are in. i wasn't saying nothing to like, nothing was happening. To no avail will my computer not stop restarting.

 

You're sure? That 4-pin block often gets forgotten. As for the reboots, keep working through your list of components. The CPU may have been damaged by the old power supply, for instance.

 

...it keeps restarting.
What else should I look for?
