Sudden blackout

I bought a new motherboard and installed fx 4100 as my processor. Everything went smooth, installed all applications and drivers on the disc, even update the bios to f7.

I played for a few hours then shut it off. Next morning, when i tried to open it again, it won't boot, black out. And sent it to the retailer and found out the board was the problem.

They replaced it, and now I have the same problem, I also did everything I mentioned above, after some restarts, black out again.

Are you sure they actually replaced it? Wouldn't be the first time someone has sent back the same part.

What is your PSU? 900W is way way way more than you need and you left the brand/model off.

Well, they said they replaced it, I don't know, and it worked fine. At least for a day. My PSU is thermaltake TR2.

Try this command-line diagnostic utility for power problems.

Go to Start > Run, type cmd, then type powercfg -energy
This will generate an HTML file and so check the report for problems.

I tried the command but no html report. So I cannot confirm if the problem is the psu.
