I decided to upgrade from my Geforce GTS 8800 to a GeForce GT 640 2GB. It worked on startup. I went to install drivers through device manager, and my screen flashed black and blue lines then My monitor loses signal, same happens if I use my TV.
So naturally, I unplug the card, boot with integrated graphics, and uninstall the drivers. I then re insalled the card, which booted normally. This is when I tried a different approach. I get the drivers from Nvidias website, use express installation, and of course barley half way through installation, screen gets black and blue lines and I lose signal.
By now I've lost my patience. So, I did my research. Yes, my Bios is set to PCI-E as default and NOT integrated graphics. My PC uses BIOS and BIOS only. Not UEFI. I don't believe it is compatible. I can't find secure boot option anywhere, and the card works until the driver is installed, so that is not the issue. Yes, I have used driver sweep to ensure ALL previous drivers have been removed. I have tried installing in safe mode. Same problem, also I have tried with anti-virus off, and windows defender off, and disconnected from network.
I'm about to get a full refund and just buy a 650. Here are my computer specs.
Mainboard: MSI 760GM - P23
550w power supply.
8GB RAM
1 TB hard disk space.
AMD FX - 6100 Six core 3.3Ghz (Overclocked to 3.8)
I am running windows 8.1
I have tried registry edit trickery as well, still nothing. I am getting desperate.
