All games freezing with new video card

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 on my MOBO. I flushed the Nvidia drivers with Driver Cleaner in safe mode, and then reinstalled. Same thing. Someone suggested disabling fast-writes in Bios...did it..and nothing changed.

I'm wondering if the card is just bad? The only other thing I thought was that 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.

 

sounds like a weak power supply. It's recommended that you have at least a 300-350W PSU to run a 7600GS. Do you know how many watts your PSU puts out? If not, you can take a look at the sticker on the side of the PSU

What brand/specific model is the card?

Welcome to majorgeeks

 

Thanks for the welcome. I am running a ENERMAX ATX 12V 350W.

Here is a link to the card:http://accessories.us.dell.com/sna/productdetail.aspx?sku=A0752807&cs=19&c=us&l=en

PNY Nvidia Verto GeForce 7600gs 512mb AGP 8X DDR2

thanks!

 

how many amps on the 12v rail? On newegg.com, the BFG 7600GS needs 350W with 20A on the 12v rail

 

How do I find that information out? I bought my PSU from newegg, but the specs are not accessible any longer.

This is my PSU: ENERMAX EG365P-VE(FM) ATX12V 350W Power Supply

I'm going to look inside and see what I can find.

 

Here is what I found on my PSU: +12V / 26A

Does that help?

 

yea it does. your PSU should be fine then.

i wanna see what other ideas people have, its late here=no brain power lol

 

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?
