Check on the device manager to see if the display hardware is working property. Click on Windows Logo> Right click Computer> Properties> on the left column, find "Device Manager"> Then in those lists, find "Display Adapters" and What's your driver version? 12.xx-13.xx? Try scanning for hardware change by right clicking the Display Adapters. Let us know what's going on. Re-installing Windows would the the last thing to do.
Driver is 13.1, I downloaded early this morning.
No changes in hardware no problems.
Windows rates it 7.9 if that helps.
Nothing in windows update.
Put skyrim in windowed mode and lagged badly,
World of warcraft same effect. When I turn the camera left and right to look around it's really jerky and I get 1-5 fps.
Lets try doing graphic test like 3DMARK11, MSI KOMBUSTER, or UNIGINE. See if one of those you used lagged as well. If it is then something is seriously wrong with the system. Resetting BIOS, check cpu usage, use MSI afterburner graph to see if the graphic usages are at least above 60%. If it keeps dropping instead of going up then its probably the card. Before sending the card back, do a fresh install on OS, before you install the drivers for AMD. Let the windows completely finish the updates. Keep checking till there aren't anymore updates available at the time. Then you can start installing drivers for the card.
