The charity I work for had another PC donated approx 4 weeks ago. It is AMD Athlon XP 2000+ 1.67 GHz, 512MB RAM, 40GB Hard Drive, 64MB Graphics, CD/DVD x52. Untill Yesterday, it worked A1 OK. However, it was on the floor awaiting a desk. When moving it onto desk it stopped working. Absolutely dead - no sign of life atall - even the fan does not try to move. Fuse is OK - power lead works on other machines. Checked all connections and none loose. What can of happened? (The moniter is connected to same power supply and power is delivered to that)

If the power supply and case fans don't work when you click the power button, either it's unplugged or the main power switch (back of case) is OFF.
But you say the monitor gets power, so I would change the power supply.

well, it *could* be the power supply. but i would try reseating all the cards. including ram. look at processor, reseat that if you can. wiggle all the cards, any loose? any smartalec kids around? check the voltage setting (red slide switch near power cord connector on pc) make sure it is set for 110 (120) not 220 (240). dead is usually easy. check pwr supply voltage setting, reseat processor, ram. watch boot attempt with case off. any lights? any action at all? you could start pulling cards and drives to see if one is dragging pwr supply down below 'ok to run' voltage but i have never seen this be the reason myself for dead box and depending on how hard is to yank power supply, next easiest test would be exchange ps with known good power supply (steal from another pc temporarily). you can also test power supply outside of pc if you have voltmeter. you will need to hook up a hard drive to it so it has load otherwise can't get good reading on switching power supplys. find black ground pins and examine other pins voltages relative to it. should get 5V DC a few places. but ps easier to test usually by replacing ps. fuse could look good but be blown but that is unlikely also.

it was PS - but how can it be working 1 minute and not the next. AllI did was lift PC off floor!

My guess is the video card back partially out of the slot. AGP Cards are real bad about that. Most newer boards have a locking mechanism on the back of the card. I would reseat the Video Card, possibly the RAM and try again. Other than that, the power supply. Also make sure you turned on the switch on the back of the PC. I've seen some people not know it is there.
