No fans turn on and when i hit the power button nothing happens. Any tips? i've taken it apart checked everything and it's all in correctly the cord to the power button are hooked up correctly.

Could be a lot of things
by wpgwpg / April 26, 2013 7:05 AM PDT

It could be the power supply, motherboard, RAM, hard drive, bad power switch, or possibly even the CPU. If it beeps, you might be able to look up the codes, but otherwise I'd either take it to the shop for repair or throw it away. Taking it to the shop is likely to cost you at least $150, so depending on how old it is, it might or might not be worth it. When we paid $2000 to $3000 for PCs, it was worth having them repaired, but nowadays it's more like TVs; when they crap out I often just replace them.
Good luck.

Some checks

All too often the PSU(power supply) fails. You mention of the GPU(video) message could be a clue because its very power hungry and video takes down a PSU. If you have another video card, try it. If not BUT maybe some on-board video port, use that, remove video card and check results. If still no go, then replace PSU with similar or better wattage unit. You can also reduce the power demands, disconnect whatever to reduce power, like all drives, etc., minimize the system so it can still work, what are the results? Take it from there or do the above, replace items.

Your reply doesn't offer if there is another video source. No banter, please provide all you can. Did the cpu fan "twitch" when power applied? Unplug main AC power for 5min. then reconnect and apply power to PC, what is the reaction? if nothing seems to work and you tried the "short PSU pins Robert mentioned" google for that tip. If it still doesn't work, then get another PSU, if you have a spare around use it. Does it beep when power applied?
