Hello all,

I hope you can help.

I have a Compaq Presario F500 with Windows Vista Installed.
This evening I was working on the computer with a laptop fan plugged into one USB and a Jump Drive plugged into the other. I used the Remove Device to remove the jump drive and everything looked fine. I came back a bit later and the screen was black, but all of the power lights were on. I pushed the power button until the computer turned off and then pushed it again to restart it. (did I mention the battery is in and the computer is plugged in?) All that happens is all the power lights, network lights, DVD lights go on. The DVD drive makes the typical single or double click that it always makes when booting, the fan powers up for just a second, the lights stay on for a few seconds and then they flash off and try to start again. Nothing comes up on the screen.

Here's what I've tried, in about the order that I tried it...
1) Push power button and hold down F8 just after pushing
2) Push power button and tap the F8 key for some time
3) Unplugged the power cord and tried to start it (same result)
4) Took out the batter and plugged the cord back in
5) Opened up the RAM compartment and pulled out each of the RAM sticks one at a time and tried placing them in each others slots. (every combination)
6) Pulled out the hard drive and reseated it
7) Pulled out the DVD drive and tried to start
8) Tried various combinations of the above, but can't guarantee that each possibility was hit.
9) Pulled out the battery and unplugged the cord and pushed the power button for 90 seconds. Then plugged the cord back in and tried to start.
10) Pulled out the hard drive and the battery and tried to start

All of these attempts yielded the same results. Completely blank screen (doesn't even flash), flashing or stable power lights, few DVD clicks, brief fan usage, no real sound from anything else.

For the past two weeks, the computer has locked up and the screen has gone blank about a total of 3 times requiring a restart.

What next gurus?

Thanks for your help.
