PC Boot-up Issue and Possible GPU problem.

Hello there! Hope this is posted in the right spot.

Just about a month ago I built my first pc with the help of a friend.

Windows Version: Microsoft Windows 7 Ultimate Edition Service Pack 1 (build 7601), 64-bit

Processor: Intel(R) Core(TM) i5-4670K CPU @ 3.40GHz

Graphics Card: Intel(R) HD Graphics 4600

Total RAM: 7.7 GB

And a 530w Power supply.

Every now and then when I turn my pc on something annoying happens.
I hit the power button and the fans start to spin and the led lights light up for about half a second and everything shuts off immediately. Then if I wait for about 4-5 seconds the pc turns on and stays on and I have no further problems with it. That's my first issue that I would like to resolve.

My second issue is installing a GPU. I was given a gtx480 by a friend and installed it into my pc. However when I start up my pc my monitor displays a blank screen. The pc does turn on but doesn't output any video. I looked at the gpu while I had the pc running and noticed its fan wasn't running. I tried the process once more and noticed the fan tried to spin for about 1 second and then stopped. I've been told their should be no problems with the 480 but I have yet to try it in another computer.

I don't know a whole lot about computers at all, but I feel like the two issues may be related to my power supply. I know the wattage is said to be too low to support the GTX480 but I want to know for sure, especially with the powering on issue I'm also having. Any help or advice would be greatly appreciated.

  1. 530w is plenty of wattage, but I'm sure it's a very low quality unit, which is worse for a system than too little power. Do you know the brand and model of your power supply?

    Regarding the 480, do you have the power connectors plugged in to it?

    I do have the power connectors plugged in when I connect the 480. I also have the gpu connected to my monitor if that question was about to come up. I'm having the person I received the 480 from test it in his pc this Friday. If it doesn't work then I'll know its just a busted card and not my pc's fault. However, graphics card problem aside I would still like to know why my pc has this power on/off/on problem?
