Hi everyone.

It uses a 6 pin power connector, as my other card radeon 6850.

Sandy Bridge 32nm Technology

8.00GB Dual-Channel DDR3 @ 665MHz

MSI P67A-C43 (MS-7673)

149GB Western Digital WDC WD1600AAJS-00B4A0 ATA Device (SATA)
931GB TOSHIBA DT01ACA100 ATA Device (SATA)

HL-DT-ST DVDRAM GH20NS10 ATA Device

Cooler Master 500W RS-500-PCAP-A3

Any help is appreciated. Thanks in advance.

Reseat the video card, check the connections, and reinstall the drivers. Use DDU for removal. Get it here, http://www.wagnardmobile.com/DDU/

Not a good name to have here, some may take offense to it.

Id also update the BIOS on that old(er) board to the latest version. Sometimes with newer cards, the boards don't play nice.

Is yours the B3 version?

If so, here is a link to the BIOS page (instructions on how to flash are in the manual) - http://us.msi.com/product/motherboard/support/P67AC43_B3.html#down-bios

My first instinct is the same as EarthDog, update the BIOS on the motherboard.

Done that after I tried removing the driver manually, and it worked great, thanks for the info.

PS Meant no offense with nickname, just the first one that came to mind.

Done that aswell, and it was the problem most likely. I removed the card drivers manually like i said in previous reply, and couldnt make the version numbers. But im pretty sure the first number was 1 since i've never updated it.
So thank you also, and happy new year to all of you guys that responded. Cheers!
