I purchased a used computer and after bringing it home I am unable to turn it on. I've stripped it of everything except the PSU, MOBO, Processor, and Case. When I hit the power button, the Power LED will turn on for 2 seconds, then turn off. 3 seconds later, it will turn back on and the MOBO Speaker will give three long beeps on a loop. Nothing appears on screen.
Steps I've already taken to try to fix:
When I tested the computer at the original owner's house, I noticed that there was a delay after I hit the power button before it actually powered on, but I thought nothing of it. When i got home, I swapped the installed HDD with two from my old computer. I don't see how that could cause whatever's happening, however.
Please help me fix this!
Steps I've already taken to try to fix:
-Testing with and without RAM (two sets)
-Testing with and without a keyboard
-Swapping PSU
-Clear CMOS (At least I think I did)
