Video Card/PSU Problems?

[Cildaten]

Ive had this problem for almost 2 weeks now. Ive posted everywhere, called everyone I know, virtually tried everything. I cant find a solution anywhere.

The Problem is...
My computer, on bootup, wont display anything on the screen.
At first I thought it wasnt posting, as It gave me 2 beeps. Which for my computer, was the code of not detecting a video card. So I tested everything Im my computer.

Unplugged everything. Tested everything. No luck
Luckily my computer has a on-board video card. Plugged my monitor into that an everything booted up fine. Visual on the screen and everything. So next I thought it had to be my video card. So I bought a new one. And before I bought a new one, my old one appeared to not run at all, fan wasnt running or anything. So once I got my new card put in the computer, I turned it on and still the same problem. At this point I was completely stumped. So for the hell of it I put in my old one back in to try it. It finally posted and appeared to be running with the fan spinning and everything. But I still did not get a visual on the screen. 2 weeks later after asking everyone I know and posting everywhere I can find, I'm here.


I just put it back in my comp and booted up and let it sit there for a few minutes... Blindly, I moved my mouse around to try to click my a login name and eventually I did and I heard the windows startup music come on.
People have told me that the PSU was dying and not giving enough "juice" to the video card. I'm about to buy a new one but I wanna make sure first.

So guys...and gals... anyone have any idea on what the problem may be?


-Thanks

Since you suspect that the PSU is not up to the task,
You can use the following for reference.

• eXtreme Power Supply Calculator v2.0

Already tried that, I hit 285
Plus Ive had this card running for a year now, no problems till now.

That can happen, runs fine for a year, then problems crop up.

Non-gamers like me can scrape by with generic branded psu's, but if you have a serious video card in the system and push the system by gaming, it will eventually take its toll. You need a psu from a reputable manufacturer:Enermax, Fortron (FSP), Seasonic, Silverstone, etc. SPCR (link below) has very good psu tests.

I'm a gamer, but I dont push anything to its limits, overclocking and whatnot. But anyways, I think I might have solved my problem. My old video card is junk now and the one I ordered works but I need a better PSU. Its going to be 680w with +12v, 22a. That will support my computer needs.
