I recently had a Sapphire ATI 9800 Radeon Pro (256mb) go out on me, so I decided to upgrade the card. I bought a GeForce 7600gs 512mb DDR2 (AGP 8X).

Knowing the problems with switching from ATI to Nnvidia, I went ahead and formatted my computer. I installed the new card and drivers, and everything went fine. Except...every game I've tried to play (Madden 2k7, Oblivion) freezes in about 20 seconds. I usually don't even get past the menu screen. The music will sometimes still play, or it sounds like a CD skipping. It either then goes black and I have to hard boot, or it crashes to the desktop. I uninstalled the games, and then reinstalled. Same thing. I updated the drivers again. My only thought is that maybe the new card is just bad? Or, maybe my MOBO: http://www.msicomputer.com/product/detail_spec/product_detail.asp?model=K7N2_Delta-ILSR is not compatible with graphic cards that run DDR2? (I know little about this stuff )

Any suggestions would be greatly appreciated.

when you changed cards did you uninstall the rafeon card,before installing the nvidia card? for a 7600 the best drivers around are the 84.21 drivers.

edit:disregard the first part i see you reformated,but try the drivers i listed.

I'll try those drivers, thanks!

1st: tried those drivers, Pharoah...and no luck

Well, things just got more interesting, and I think this may be a much larger problem. A few days before my ATI Radeon 9800pro went out, I kept getting atiVdag bluescreen (something like that) errors..."stuck in infinite loop." Went through all the driver cleaner stuff then. Then, one morning, I had the lines across the screen like the card had fried. That's when I got the new card, formatted, and everything was fine until I tried to play any video games.

Well, about thirty minutes ago, I started to get bluescreen errors for the Nvidia rather than the ATI...called n4_disp ---stuck in infinite loop. It then made the system reboot. In other words, it seems like the problems are reoccuring now....with a formatted system and on a totally DIFFERENT card.

Any thoughts? Could it be a MOBO failure?

pharoah

mobo failure its possible,but still could be software.are your windows up to date?

edit: list your full system specs,and power supply brand/model etc.

Thanks for the help, Pharoah, but I think the problem is solved. For amusement I called the tech support of the card manufacturer (PNY), and once they stated all the obvious they told me it was a faulty card. I returned it to CompUSA, got a new one, and it works.

The only weird thing is that the card I put in today looks totally different from the old car (colors, fan style, etc). But most different was that it was a AGP 3.0 whereas the other was a 2.0.

if it works thats all that matters.glad ya got it working.
