Pixelated Screens

Hello everyone, I'm having quite an annoying issue.

Whenever my computer starts up, it goes through a series of unreadable, pixelated screens. I have a nVidia 6800 Ultra with an Antec 500W PSU. One of the two fans on my PSU is not spinning, considering my video card requires a minimum of 480W, could that be my problem?

I know my monitor works perfectly and I'm confident in my motherboard and RAM.

Any help is greatly appreciated.
 
I'd say your video card is overheating, and the fact that one of your PSU's fans ain't spinning is because it only spins when the PSU's temperature get's too hot and needs more cooling.
 
Thanks for the reply...

I don't see how it can be overheating, considering I've kept the computer off for 12 hours before I restarted it.

Never does any good.
 
This is not a problem with the video card or the monitor; this is in fact normal. You most likely have a LCD monitor (flat panel), right? All LCD’s must run at a native resolution, for example a 17” has to run at 1280 x 1024. If not, then you’re going to get “a pixelated screen”. During startup, the computer uses a default resolution of 640 x 480 or 720 x 400, that’s why you don’t get this problem in Windows. Unfortunately that’s one of the drawbacks of owning a LCD monitor, CRTs don’t have this problem.
 
Thanks for the help...

According to BIOS, my system temperature is 37 degrees Celsius and my CPU temperature is 42 degrees Celsius.

I'm running on a CRT monitor, it's also had the same problem on a different CRT monitor.
 
That really does sounds like a video card problem. Is it a fact that your video card needs 480W, that seems excesive...

Have you updated your drivers? (Although you should still be able to read things without drivers)

To check your video card tempatures (for NVIDIA) you need to open the forceware program (or NVIDIA settings, probably on your taskbar) and click on tempature tab to find out the temps. (Don't freak out if the temps seem high, video cards are designed to operate at higher tempatures then CPUs, just tell us the tempature, we'll tell you if it's to high!) :)

That's the thing, I can't even get into BIOS when I start up my computer with the 6800 Ultra.

Is there anyway to keep my 6800 Ultra in the slot, but log into my computer with the motherboard video and download drivers for the 6800?

Click to expand...

ya if you have intergraded graphics... That's done through BIOS...

Is your card still in warrenty?
 
I customized my computer on a site and they built it for me.

I don't believe they gave me a specific nVidia warranty, just a one year warranty for the entire computer... which has expired. :(
 
Well, it's obvious my 6800 Ultra is ruined...

Due to this card annoying me and having great experiences with ATI in the past, I've decided to get a X800 XT.

Several different people have said that my PSU possibly fried my 6800 Ultra, would it be necessary to get a new PSU?

My PSU seems to be running this motherboard display and the X800 XT requires 350 watts unlike the 6800 Ultra which requires 480 watts.

Is my video card under warranty if my PSU fries it?

Any information or advice is appreciated...
