[SOLVED] Black Screen until Windows loads

Good thought. Do you know which psu you currently have and/or its maximum watt output rating?

Hey,
I have this one:
http://www.corsair.com/products/vx/default.aspx

Corsair VX550W Specifications: Model CMPSU-550VX

AC Input Rating 90 - 264VAC
DC Output +3.3V +5V +12V -12V +5VSB
Max Load 30A 28A 41A 0.8A 3A
Max Output 140W 492W 9.6W 15W TOTAL POWER: 550W


I found it by using the on-line corsair tool to help identify how big a psu you need, and I checked with Gainward and they said minimum 450W.

So if its faulty or just not enable to generate enough I don't know, and I'm not entirely sure its to blame =/

Corsair is a great name, if not the best, in psus.

The rating on it seems to be sufficient as well and can very likely be trusted (others at times can not.)

What you can do if you are up to it....

Connect the video card to its own seperate psu to test how it goes like that. All you'd need to do is put a paperclip to connect two wires in the part of the psu cable that attaches to the motherboard normally - one part of the paperclip in a green wire and the other end of the paperclip in a black one. This is so the psu can be turned on.

Then attach the psu to the video card itself. Turn on the standalone psu and then turn on the pc. See how it goes.

If this experiment goes well and the video card now works, then for sure, buy a new psu to install in the machine.

Hey,

It sounds like its worth a shot and who doesn't like the chance of getting electrocuted?! ;-)

I will try it out later and report back with the result (hopefully ;-) )

week a go 50a and 750w to run the card

Hey,

I tried out the tip with little luck although it was fun

The psu it tried it with was only a 450 W so it might not have been enough, but the problem with a black screen and a signal to the screen continues =/

So you are sure its due to too little power? How did you find that information?

Your old GPU requires a single extra power connection doesn't it? But the fermi takes two PCI-e connectors. It is best if those two connectors be on separate wirings directly from the PSU and that nothing else is on either wire chain. Is this how you have them? Does it work if you boot in safe mode?

Also, you are actually swapping out the graphics cards correct? You don't have both the new and old in at the same time?

Hi,

No my old one is really old and doesn't require any PCI-ex connector and yes the new one requires 2. They are on separate wiring directly from the psu and nothing else on either wire chain, exactly like you describe.

Yes I am swapping them out

You definitely don't have a psu issue if the experiment didn't cause things to work well. The two power supplys working together to run the system was far more than enough necessary, with respect to total output wattage.

It's good you did the experiment so you could now rule that possibility out.

Have you tried another monitor yet?
