Hello,

I'm having this weird problem and i think my video card or its driver maybe the cause, my card is an HD 5670 It works fine running games but since the last week it's been giving me some trouble.

My PC won't restart it hangs on the shutting down screen, I have to reset it manually, Sometimes I can't open some programs like EA Origin, the little circle that tells you to wait appears and the program won't open, when I try to install a program the installations won't progress and I can't use windows aero, etc.

This could sound like an OS problem but I have reformated my PC and just as soon as i install the drivers for my video card, the problems begin, I have also updated the bios, also when I switch to the integrated graphics chip of my motherboard the problems are not present.

I have also tried to use the latest beta driver and the problem persists.

My specs:

Gigbyte 880GM-D2H Motherboard.

AMD FX 6100 Black Edition 3.3 ghz

Windows 7 ultimate

8 Gb RAM

Radeon HD 5670

Thanks in advance, hope you could help me.

Sounds like a faulty card to me, though I cannot be sure of course. I suggest you try it in another computer.

Thanks for your help, but unfortunately your suggestion didn't work.

My mother's PC has one of my old Video Cards, (Radeon x1550) I switched them, installed their respective drivers and my current Video Card worked perfectly on my mother's PC, while the problems persisted in my PC with my mother's card.

The only actual improvement i saw was that I was able to restart my computer, but I'm afraid that won't last too much.

I'd like to know if there's something i could change in the BIOs, perhaps?

I didi as you said, cleaned all the drivers and installed .net 4, also I removed an sd card reader and replaced it for a newer one, The restart problem of programs that didin't open are now solved (I also gained lots of performance) but I still can't gt aero to work.

Anyway, Thanks for your help, I'm not sure if your sugestions or replacing teh sd card reader solved the problem restart problem, but I aprpreciate the help.

Ok, I have already solved all the problems here's the summary of all sulotions:

- The restart problem wasn't caused by the video cards's driver, it was caused by a defective SD Card reader, so i changed it and I was able to restart again, Along with that I gained a lot of performance on my PC.

- About the windows aero problem definitely the video card dirver had a lot to do, so here's the solution:

Download "Aero enabler" from here:

Intall the program and then run it, It will force aero, even if the system tells you that your video card doesn't support aero (Which wasn't my case, my card was able to handle it, But i needed to force in order to be able to use it) by editing the registry.

You can unistall Aero-Enabler if you wish, you will still have aero enabled even if you do so.

To all of you guys thanks for your help
