[SOLVED] My pc won't turn on but it turned on for 2 secs

[GioSs]

I've had my pc for 2 years and i've been having some problems now it's pretty old i have a dell optiplex 3010 with a cheap AMD card i don't remember . I started having these shutdowns two months ago and when i was playing a game any game it shut down randomly i put my maximum power down and it has not worked till now. Yesterday it shut down and i tried to put down some settings with AMD and that seemed to work until today. This morning iit started turning on and off i thought it was no problem then i left it alone. I had to restore my pc from a update and when i was getting my stuff together it shut down randomly i was doing nothing. I tried and tried i pulled the cables out it started once and now it won't turn on now. Any help or ideas of how to fix this problem im really annoyed. Everything seemed fine inside some dust im trying to clean out

If it were mine, I would remove the AMD graphics card and try with the on-board graphics (the video connector on the motherboard), reseat the power connectors on the motherboard (the cpu +12v and 20+4 connectors) and reseat the ram. After a good cleaning of course, which I tend to do in the garage with a compressor and a pencil or toothpick to prevent the fans from spinning out of control (bad for bearings, and compressors are really high power). It's a good first step.

If nothing, try the paper clip power supply test and see if the power supply can work on it's own accord. I would remove both motherboard power connectors and leave the CDrom and fans connected just to see them spin and eject the tray. Probably the only time the CD tray gets any use at all these days lol.
