Thanks for the response. I know just enough about computers to get myself in a jam.
onboard video? Not real sure. There isn't a vga hookup except on the AGP card.
Both of the video cards are AGP. The motherboard is an 4x/8x AGP, but only at 1.5v.
Yes, the RAM sticks are in the proper order.
The new PSU hooked up ok and I didn't take out the mobo, just cleaned it real good. But I've rechecked and reseated everything. The monitor is working, I checked it with my laptop.
What could cause the HD light to stay steady on? It comes on when the power light comes on and stays steady till you shut down the computer.
A real quick history of the CPU and video card. They are all that is left from a Dell computer I had. Not to bash dell, but, I had the one year warranty and the computer had to be fixed 7 times, (PSU, CPU or Mobo, or a combination of).
I started out with a P4 2.4mhz and by the time the warranty was expired, I had a 3.0, (and the 3.0 fried one PSU). So the CPU and video card has been through problems.
I've found a new 3.0 Prescott at newegg and they also have a couple socket 478 Mobo, so I think I'll try a new CPU and if that doesn't work I'll try a new Mobo. By then I'll have a new, old computer. If I can limp it through about 8 months, I'll build a new one.
