Hi, last week i started having a problem with what i assume is my graphics card, i would play a game and a few minutes in the screen would go black and i would still get sound but the driver would not recover forcing me to do a hard reset on my machine, so i assumed the graphics card (a 6970) has had its day, i purchased a 280X to replace it, upon installing the card the system would not turn on, so i refitted the 8/6 pin cables and tried to turn it on again, the card went pop and some smoke came out of it, that led me to believe that maybe my PSU (Coolermaster 1000W) was faulty, so i bought a new PSU (corsair 750W) and put the 6970 back in (I had RMA'd the 280X incase there was already a fault with the card as it was ex display), anyway the computer started fine i ran furmark to make sure the card would not crash the PC which it did again in under 60 seconds, these crashes also occur out of games now but if i uninstall the drivers for it and run the PC under the standard VGA driver it never crashes, other things i have tested are RAM, CPU, HDD's, checking for any loose molex conections, reformatting and reinstalling window, I'm at a total loss, everything seems fine, all temps are good, I'm stuck now as to what else to try, any ideas folks?

What I would recommend you do? Is uninstall the drivers from your old card. This is what you do, plug 6070 back in your motherboard and boot normally. Download the display driver uninstaller on this website: http://www.guru3d.com/files_details/display_driver_uninstaller_download.html

Then after you download, reboot on safe mode. Use the program to uninstall the drivers. Shut the computer down and plug 280X and boot normally. Just update the graphics card and you should be fine!

Already tried all that, not being rude but please read the original post. any one else got any suggestions, I'm thinking that its the 6970 that's faulty but i can't try another card as the 280X got sent back on an RMA.
