Purchased a bare bones kit back in February with a XFX nForce 680i Motherboard and a XFX geforce 8600 GT XXX graphics card. After assembly, the computer worked fine for a few boots and then the Nvidia graphics card support software stopped working and the graphics card showed in the device manager as "this device will not start." We also had two sticks of Corsair RAM go bad. The bad memory has been removed, leaving 2 gigs of preinstalled memory. The graphics card drivers have all been reinstalled multiple times (using both the drivers disk and updated drivers from the XFX website. The graphics card will seem to work until you reboot, at which point it goes back to "this device will not start." The system software is Windows XP Pro.

As far as the detection of your card goes, you need to go to bios setup and check if your 'on board graphics' is enabled, it should be disabled. i can help further if you give your motherboard model number.
the problem with the vertical lines may be that there is dust in your cards PCI socket on your motherboard or the pins on your card might have got damaged when you were cleaning them.
Pull out the graphics card & RAM chips. Give their contact points a good cleaning and replace hem. Also check to see that all cables are snug tight. Finally remove the Monitor cord fro its slot at the back of the CPU and remove all dust and check if any pins are loose. See that the monitor plug is firmly placed..................sodeep
contact the shop / place you purchased it from and they should be able to give you info of where to send it and what to do - they should have a section on there website where you can go through the return process and you will most likely need to get an RMA number to authorise the return / replacement.
Do you have an onboard graphic slot too . you could remove the XFX card for now . Install all other drivers on Vista first and then try your card again. Just try and single out the problem. Does the driver cd come with vista drivers ???
The XFX NVIDIA GeForce 8600 GT 256MB DDR3 PCI Express card uses two DVI ports on the back of the card. Display is most likely coming from the second port. Try moving your monitor cable to the next DVI port. You can do this while your system is running. If you still do not receive display, post that here & we'll go over some other possibilities.
Good luck rohit1987!
