Ok well here is my problem, I bought a computer on Jan. 31, 2009. And Yesterday I had two good graphics cards on my desk. So I decided I'll change mine. I put in my ATI Radeon HD 3650. I ran Crysis All Very High settings little lag. Then I tried the GeForce 9600GT It worked then I restarted my computer and it didn't work and I was like, "What the hell?" So then I took it put in my original GeForce G100 512MB ( At least that's what it says on the card ). Plugged in my DVI Cable and unplugged my Blue monitor cable(forgot what it's called). And the monitor went blank and said No Signal so I plugged the blue cable back in and it worked. Put the PCI-e slot is reading my card because the fan is on. And not 1 of 3 cards are working. Any solutions? I voided the warranty of my computer by opening the back.

System Specs:
4GB DDR2 RAM
640GB SATA HDD
Card says Nvidia GeForce G100 512MB, My monitor says Nvidia GeForce 7100/Nvidia nForce 630i ( I don't know why)
Intel Pentium Dual Core Processor 2.4 GHZ

Remember to UNINSTALL previous gfx drivers before installing another card (even if it's the same type of card). Also power off the monitor, and power it back on, it could be having issues switching between DVI, and VGA. The 7100 sounds like the onboard vid, it could have defaulted to it in the BIOS, change the initial display to PEG.

You did NOT max Crysis with a 3650.

I ran it on Maxed settings on 1024x768 Res. I could on run on mid/high with 1600x900. Anyone I found out the problem I brought i back from where I purchased it the whole computer was messed up from jump street. It never detected the Nvidia GeForce G100 only the Chipset. So they gave me a brand new one and It detects it.
