Windows 7: nVidia nic driver will not stay working

I'm having an issue with keeping my nic driver working. It is an onboard device and I went to nVidia to get the new driver for Windows 7. It will work sometimes and other times it will not. On the "NOT" times I have to go in and actually uninstall the device and delete the driver from the System32 folder. Then, I reboot to get it to reinstall and 98% of the time it works them.

Any suggestions? i'm no newbe to computers, but this one has me stumped

Hi wizard welcome to sevenforums

First thing we could use all your systems spec's. waiting on info

Sorry, thought you could pick that up through the profile.

Anyway, I am running a homebuilt GeForce 6100-M9 MB, AMD 3300+ Processor w/2 gig ram. ATI Radeon X300/X550/X1050 Video w/a Hauppauge TV tuner Card. The onboard sound suddenly quit working, so instead of looking into the problem, I just put an Envy24 sound card into the system. My nic is onboard, as I stated, and I would just put another nic into the system, but I have no more PCI slots.

Thanks for your patience, everyone

i have Almost the same setup and i have the exact same issue..

Biostar Geforce 6100-m9 MB, Nvidia 8800gt, 2.5gigs of ram

the difference is if its not giving me the BSOD with Ndis error for "IRQL_NOT_LESS_OR_EQUAL" its just plain locking up on me..... the whole system just freezes up and i have to hard shut down and reboot.... 20minutes to 2hours... no consistency whatsoever...

i'm beginning to think this board is just not compatible....

one small thing i have noticed.... i originally tried to troubleshoot the freezing by installing the XP drivers for the motherboard, this i think caused the BSOD...after uninstalling and letting windows autoinstall the Nic drivers as it wants to i havent had a BSOD however still freezes.

Really wish Microsoft could make an OS worth a damn from the start....I've had nothing but trouble with Vista and 7 so far....
