I have a Dell Dimension 4700, running Windows XP that constantly crashes. It just dies in the middle of doing ANYTHING. It causes the screen to go black and it sounds like it whirs down, then the power light turns yellow and blinks.
To restart it, I have to depress the power button for about 30 seconds until it actually shuts down. Then I have to wait a while (a few minutes) before I can press the power button to get it to restart. If I try ot turn on the power too soon, it just yellow blinks at me.
Then it's a crapshoot for how long it stays on.
I've added no new hardware or software and I get no error messages.
Any ideas as to what's going on and/or how to fix it?
