400watts seems rather low for a power hungry beast like that. Perhaps a more powerful power supply will get your system working properly.

i have tried the whole systems with one hardrive without dvd-wr,graphics and two still kept on shutting down by itself...the shutdown only happens when i boot a operating systems...sometimes i boot successful using the option called last known good configuration(advanced). and installed a software to show the temperature of the cpu.the cpu temperature is about 32c to 36c and the systems is around 35c to 37c..when i turn on the computer and i go to bios..i can leave for a day on the computer doesnt go off as soon as i go to windows 7 it goes off.

Re: PC shutdown by itself. 80 80

I suggest getting into windows using `last known good con....` as you did before, then set chkdsk to check your hard drive on next reboot, also while your in windows 7, make yourself a`WIN 7 system REPAIR disc, simply type recdisc.exe in search and burn to cd. hope this helps..
