Compaq Evo D51c (HP lists as D510 Minitower)
Windows 2000

I was doing some work with the machine over my network (it serves as my server of a sort). Windows hung in while RealVNC was in use (without my knowledge). I had to do a hard power down. After that, the PC will not boot. The power supply and processor fans turn on, but the nothing further happens. Black screen only and no self test POST beeps.

I believe this is a hardware issue and I can use any advice on where to start hunting down the problem.

I believe this is the correct model:

I have now cleaned the contacts of the RAM and also the socket to no avail. The first time after boot, it didn't give the error code, but after the memory check, colors just started flashing on the screen. After a rebooting, it went back to square one: black screen (monitor saying no valid input) and the computer hanging.

I am reseting the CMOS now and hopefully I can try a couple of other things... but this is where I am now.

The RAM is a 512 DDR PC-2100 with CL 2 I believe.

SOunds like a video card issue. Is the video on-board or a separate card?
