Hi I recently bought an Aopen GeForce 6600GT 128mb graphics card to replace my old Geforce 5200. I installed the card no problem. But when i started Doom 3 it had loads of black squares over the graphics. It then bombed out. I restarted my computer and i found that the startup screen looked odd. There were blue lines down the start up screen - (My computer is made by Advent and when it starts there is a white screen with Advent in big letters on it). My windows in 'windows' looked odd. There were 'blue tinges' below any text in a white window, the desk top looked odd almost, like I was running in 16 colours even though i wasn't. I found out it could be the power supply which was only 300w.
So i bought a new one and installed a Hiper 525W power supply which is a very good power supply. I thought this would solve the problem but when i started up, the Advent startup screen again had blue lines down it and the desktop and other windows look odd. After a couple of restarts the computer won't boot up at all, it gets to the windows screen then the screen goes black, a mouse pointer appears then it freezes and my computer beeps and crashes.
I have reinstalled my old Geforce 5200 and that works fine. I have tried everything. I have looked at up[censored] the motherboard, a micro ATX (though not yet updated the bios, even though the bios is pretty new anyway). I have installed a new power supply. I have unistalled all the drivers and renstalled them from fresh. I have even reinstalled windows, but i still get corrupted (Advent) start up screen and computer freezing once the 6600Gt is put in. Does any body have any ideas? Could it be a bad graphics card? Could it be that my motherboard can't cope with a graphics card of this type?
just before the Advent Screen appears I get writing on a black screen saying something like 6600GT bios etc, so the card is being recognised, and when windows did start up the card seemed to of been recognised within windows.
Thanks for any help you can give (its driving me mad this thing! ;-)
