My ATi X300 SE (PCIe) packed up yesterday someone screwed it up by accident and I need help installing this other graphic cards that I have. I've got an nVidia GeFore 6600 GT manufactered by MSI or whatever they're called. So I put it in my computer and turned it on. Everything was kind of laggy at first but I was able to use the computer with basic drivers. I downloaded the latest forceware drivers from nVidia and while I was installing that screen flickered, went black and came back but the mouse was stack and there were a few lines across the screen. I waited about 5 minutes, and nothing happened, so I decided to reboot the computer. I rebooted and about 20 seconds past the login screen it got stuck again. I rebooted again and I get the same result except it's at the Windows loading bar. The same happens with both Vista and XP. (And when I installed I was using XP, so don't blame Vista).
My computer specs are
2,5 GB RAM
AMD Athlon 64 3200+
80GB Maxtor HD running XP MCE 05
200GB Baracuda HD running Vista Ultimate
And graphics card obviously the nVidia GeForce 6600 GT
Please help me fix this.. I really want to use my computer again.
Thanks in advance,
