Having problems with your Compaq Evo D500 PC Desktop ?

Pc wont boot up, instead a red light flickers.

\015 About a month ago i formatted my pc to try and speed it up, everything went well, but it still stayed pretty slow. and last week it froze and i had to pull the powercord to reboot. and now it doesnt start up, instead when the power button is pushed, the green light next to the power button apears once, then a red light next to it begins to flicker. i suspect my power supply is fried, and i might try replacing that, does anyone have any advice\015\012\015\012thanks\015\012\015\012thomas\015

Answers :

Flickering LED means power supply is overloaded with something. It might be inside of the supply, but sometimes it is something else. Try that:
1. Disconnect everything from the motherboard except power supply and power button;
2. Disconnect all power connectors from all drives;
2. Remove any cards from the motherboard so all you have is power supply and motherboard with CPU and RAM, nothing else. You can keep connected the monitor and keyboard;
3. Press Power button. Will motherboard turn on normally?

If no - check electrolytic capacitors especially around the CPU, if some of them are "popped" replace them.
If yes - connect drives and cards one per time to localize the problem.
