Windows 7: Problem installing GPU

Hum Gary I haven't had the CD in since I installed the 7 so why that Vista like startup is happening is a mystery.

The Device Manager I found and it has the GPU listed with the yellow triangle I tried that driver option and it tells me that the correct driver is installed.

Do you think I might have a lemon GPU??

To answer Steve's query the on board graphics are perfect it just seems to be this card is stuck in a set mode of some sort and cannot be changed.

On the Sandy Bridge I have an ATi Radeon HD 5450 passive unit that has never been a problem so I am wondering if it is worth trying that in the new machine and see if it works in it?

hmm, can you try testing on a different PC?

Another issues that maybe the cause could include IRQ conflicts, but any motherboard just about has an automaticly assigned IRQ values, with IRQ conflicts being rare.

Steve had mentioned you try another GPU in the BBB if you have one. You can try the new GPU in the SB too.

Ok well I suppose if it works in the others then the Ivy Bridge board might be the problem eh?

Perish the thought though

Try the new one in your main rig. The downside will be it will install the nVIDIA drivers.

Bingo!! I just put in an old Asus AX850 I dug out of an old gamer and it worked straight away - didn't need drivers nothing - res is now at 1900x1080 and it is quiet!.

I have refurbished this unit some time ago as in cleaning , re lubing the fan bearings, re thermal etc. Most of the other "spare" GPU's are those old types that don't fit that form of slot - I think they were called AGP or something.

The colours are brilliant and so clear the text is as sharp as and I guess I must have beeen real lucky that this was the only card I had that would fit eh?

Just cannot believe it worked like magic so the GTX I guess must be faulty?

Best specs I could find at the moment and the pic is the exact one.

Well I think that means the new GPU has had the biscuit. Ask for a replacement.
It is running from the used GPU and not the on chip one?

Yes Gary I think it is because I had to change the resolution with it, it shows up in Device Manager with no yellow triangle - tells me the driver is up to date, and the monitor is plugged in to it.

So could it be running the board through this GPU though and if so how could I check that? Mind you I think the display is a better quality than when I was running the monitor off the board.

Look I just tried something and I know I shouldn't have but I swapped the lead t the board and no screen put it back into the GPU and screen perfect.

In one of the advanced menu options is primary graphics adaptor. Change it from auto to PCIe and see what happens.

Ok Steve I'll do that and get back.
