PC won't boot after installing chipset drivers
 

K, here is what happend:

PC stopped booting in Windows (was up to date with the drivers and Windows updates) so I did a format.

Without the NV 6.68 chipset drivers, it booted fine and I made a backupof the data partition. But as soon as I installed the latest chipset drivers, which worked fine before, it hangs even before the splash screen with a black screen.

The System is a 4400+ with XP SP2 on a Gigabyte K8N PRO SLI and I have no idea what is going wrong.

Can you get into windows with safe mode?

I tried holding F8 but it didn't work.

hmmm; that should be able to come up, it loads before the OS

Yes but what can it be, it puzzels me as I haven't done anything today and bam it doesn't work and even the reinstall doesn't work anymore.

problem doesn't seem to be software in this case; can be multiple things, hard drive badly partition/corrupt, ram corrupt, too high OC, soo many possibilities.

try stripping system down to bare minimum, run stock speeds, than try again;

I reinstalled again, installed the chipset drivers without the SW one and installed the windows updates.

After a reinstall I got into safe mode now, but it only shows me a DOS page with file directories?

I also had a weird DOS error pop up when I got into XP.

when you enter safe mode it'll ask if you are sure to continue, if you hit no it'll give you the recovery console = like dos window;)

nope, it almost looks like it gives an error message that it can't find those files

Would be using a the FIXMBR command in the recovery tool a good idea?

memtest shows no errors as well

that's only good if you can not even start windows (unable to locate the system/boot drive); don't think it will fix this though
