Computer Keeps Shutting Off
My computer is about 2 years old, it has 512mb DDR and has a amd 2800 xp with 240gb of space, I'm a web designer and I have left it on for the past year or so straight without turning it off.
It started doing this in july, it will shut off every 3-4 days, at first I thought it was because I had a lot of programs opened but then I tried to do a virus scan and it would shut off with nothing else opened. When it shuts off and I turn on the power button it won't come back on, I have to turn it off in the back with the switch and wait 5 minutes before I can turn it back on, is this a power supply problem? Hopefully it is so I only have to go out and buy a new power supply, but I do plan to buy another 512mb DDR as well.
Let me know what it could be.
