I have upgraded my computer in stages... I had a gateway from 2007. Then two weeks ago I upgraded to:
Graphics card: GeoForce GTX550 Ti
Power supply: 550W
OS: Windows 7 (upgrade from Vista)
After that, every time I booted the system I had to select Windows Vista or Windows 7. I always chose Windows 7 and never saw a problem.... except until I started to play Diablo 3 and other graphics intensive games where I was only getting about 10 fps and massive screen tearing. By processor was a 2.4Ghz Quad core with 3G of memory... so I assumed that it was just bottle necked with the new graphics card. Therefore I went and upgraded to:
ASUS 5A97 Mobo
AMD FX 4100 processor
8G DDR3 1600 MHz
Then when I booted up it would start windows then instantly go to a bluescreen for a split second and turned off. I dont know what to do. I have tried booting off the Windows 7 install disk and it has:
Disk 0 Partition 1 11.0 GB (total size) 10.9 (free space) Primary (type)
Disk 0 Partition 2 454.7 GB (total size) 311.1 GB (free) System (type)
and the next arrow is grayed out and when I click on one I get the error:
Windows cannot be installed to this disk. The selected disk has an MBR partition table. On EFI systems, Windows can only be installed to GPT disks.
I am not super tech savy and dont completely understand all the jargon but I can normally figure things out. But this... I am very scared because I dont want to delete the available Disks because I dont want to have to buy Windows 7 again (because I already installed it once). I am at a loss of words and ideas on how to fix this so I can use my "new" computer
Thanks, and sorry if I am being vague or unclear. Please ask if you need any additional information.
In advance... any help is much appreciated.
