OK, I've been slowly upgrading my old PC so I could get back into AH. Here's what I HAD:
Mini-Tower mATX Chassis w/350W PS P4M266 Motherboard    
    Intel Pentium 4 Processor 2.8 GHz 533FSB w/ 512K Cache    
   1024MB DDR333 PC2700 Non-ECC Memory (512MB x 2)    
   40GB Ultra ATA (5400rpm) Hard Drive    
   GeForce FX5600-8X 128MB Video Card with TV Out  (AGP)
   300W Power supply
  Now, here's what I HAVE:
    
    Mini-Tower mATX Chassis P4M266 Motherboard (Biostar U8668-D)
    Intel Pentium 4 Processor 3.2 GHz HT w/ 512K Cache   800 MHz FSB 
   2Gb PC3200 Non-ECC Memory (1GB x 2)    
   40GB Ultra ATA (5400rpm) Hard Drive    
   HIS Radeon HD 3650 512MB 128-bit GDDR2 AGP 4X/8X HDCP Ready Video Card 
   580W Power supply w/12V @ 25a
  I'm having real problems with my vid card. When I install it, I normally lose the keyboard (PS-2) and mouse (USB), but can reboot a few times and eventually get to my desktop, then the  computer locks up. I'm currently using onboard video and have disabled it and enabled it, but that doesn't help. The only way I can boot the computer is with the 3650 card completely out of the case....as in unplugged. 
  I also have bought a new 250 Gb hard drive to be installed soon.
  thanks for the help,
