Shutdown unable to power off

Specs: Windows Vista Home
So....Last October I bought my girlfriend a nice HP Dual-Core system with windows vista home premium installed from a pawn shop. Had all the info so that I could do a fresh install of Windows Vista on the drive and it was running great up until about 2 weeks ago. The only 2 things I have installed on the computer hardware wise are the Xi-Fi Extreme Gamer soundcard, and the nVidia GeForce 280i Graphics card. Now every once in awhile the computer will randomly power off and we are unable to even press - hold the power button to get it to actually power off, and I have to pull the plug. Not a virus issue as I've ran safe-mode scans and had the net unplugged. Thinking it may be a power source issue but there will be days where she can play it for hours and hours with no issue, and some days when she cant play for more than 3 hours before it does this issue. Any input would be awesome.

The power supply unit may be having a hard time to cope with the recent hardware changes and may be overheating as you have also guessed. Overheating depends on many other factors as well, such as ambient temperature, title of the game, how fast you play the game, etc.

You should calculate the power requirement of your girlfriend's PC and buy her a new PSU if the power need has increased dramatically.

You can find a good PSU calculator HERE and HERE

You may also consider re-installing the gfx card drivers, updating the other hardware drivers including the chipset drivers, etc. before making the decision to buy a new PSU.
