I've been using this computer for several years with no recent changes to its hardware or software. Last night while entering data, the monitor, fans, drives all suddenly stopped. The power LED was still lit. Keyboard and mouse wouldn't get it to do anything so I pressed the power switch and it was off.
When I press the power switch now, the CPU fan runs for a second and stops. Nothing else happens. No beeps.
I swapped in a power supply from a good pc and it behaves exactly the same. (I'm now writing this message on the pc with the good PS back in it.)
Any ideas? Failed motherboard? Failed CPU?

If it is a real BSOD you can turn off the power. Try a LiveDVD Linux distribution to make sure your hardware works. You may need to fix hardware (what changed last or recently?) or uninstall new software or reinstall Windows. You may need an expert to help you out. Do you know anyone in their last year of Junior High School (or above)?
it may be virus issue. i suggest you to try with last known good configuration so that it will take your computer to last good working state. for that tab F9(Function key) continously immediately once you turn on your computer until you get the advanced option on your screen. highlight last known good configuration and hit enter and it will boot in that mode once you get the main sceen CLICK start - > all programs- > Accessories - > system tools -> system restore and wizard will open and select Restore my computer to an earlier time click next next finish to set your computer to last good working condition.
