Here is what I would do...
Turn the PC off and unplug it. Then press the power button to drain any residual power from the motherboard.
1. Remove and reseat the memory module(s). Restart the PC.
2. If removing and reseating the memory module(s) doesn't work, if you have more than one memory module installed, remove all but one, and start the PC.
Test each memory module one at a time, until you find the one that is bad.
If none of that works, check for bulging and leaking capacitors on the motherboard. These may be particularly noticeable around the processor area.

Paul_Tikkanen provided some steps on testing the memory of the computer. Have you tried those steps?
