After recently reciving a used Gateway GT5622 from my grandfather, opened it to see what ram and GPU it was running. About 3 weeks after this, i decided to boot it up and possibly use it for bitcoin mining. I attached the cables for the power supply, keyboard, mouse, monitor, and ethernet. When I attempted to power it on, the power light flashed randomly, one of the fans was in sync with the light, going of at the same time the light did. I then got 3 beeps, and about 2 minutes later, it completely stopped and shut itself down. I learned that the 3 beeps meant a memory issue, so i reseated the ram and gpu, got most of the dust out, and tried again. There were no beeps this time, but the light and fan were still on and off, and i still got no display on the monitor. I have removing the bios battery for a few minutes, and it didnt work, i attempted moving the jumper cap on the three pins (forgot the name, sorry) and it then would not start. i moved it back, and it went back to the condition that it was in. Could anyone help?
