i recently bought a graphics card and read some directions from the manual and tried to install it. I removed my old graphics card and put then new one in without uninstalling old drivers and installing the new ones. win7 would not start up so i switched out the new graphics card for the old one. windows now will not start up, not even in safe mode or vga mode(low res). i tried startup repair as well and it doesnt work. when i try to boot it in safe mode it stops at \windows\system32\drivers\classpnp.sys
then restarts and gives me the options, start startup repair, and start windows normally.
i need to know why this is happening and how to fix it.

1. Try resetting your mobo BIOS by removing the CMOS battery for 10 seconds (with the PC off of course).

2. Have you got Integrated Graphics in your CPU? If so, try booting with the PCIe GPU out.

3. If you have access to start up repair, then you have access to system restore, right? Put the old GPU in, boot, system restore, uninstall old graphics drivers, turn off, plug in your new GPU and boot again.

4. If all else fails, do a clean install of Windows. That'll almost certainly solve your problem.
