Does the computer have power going to the graphics card? Some prebuilts don't come with a dedicated 6pin power cable for bigger cards. If unsure, the safe bet would be to find a replacement that doesn't require dedicated power.

Looks like you want at least a invidia 330 or Radeon 4670. What's the power supply wattage inside and is it a full size case or one of the smaller skinnier ones?

That's an AGP graphics card and it's a 12 year old computer. It's not worth trying to fix, especially since you don't know if the graphics card is really the problem.

I'd remove the 5 screws holding the cover and clean out the fan and heatsink fins with a glue brush. If any of the fins are enclosed (many for heat pipes are), use a pipe cleaner or small brush for bottles. Work on an anti-static surface, like a metal cookie pan or aluminum foil. If you blow or vacuum the fan, hold its blades still so they won't spin and ruin the bearing. If this cleaning doesn't help, try removing the heatsink and existing thermal grease and applying new stuff. Avoid using anything containing pure metal, like silver.

overheat is less likely if can't see it post normally.

if no freeze or hang, can get into windows normally.
try flash other firmware, or just edit the firmware to super low volt, then flash. turn on voice narrator with command blindly, enable windows build-in remote or use USB to auto run a remote program.

try replace capacitors.

Not worth trying to fix an old computer. You should use it as your practice machine.
