Hello. I just bought this pc for about 2$ to restore it. This machine is very old (15+ years). I blew out the dust with compressed air and it came with no PSU cables, so i connected it with a different one (not sure if this matter, i think its worth noting). I started it up and it started beeping. I reseated the ram and i got the same error. I'm pretty sure the ram is fine, its just very old (512 mb ddr1). Power supply is 200-300 watts.
Here is a video i just took on demonstrating the problem :
