XP boots but not Vista

[codam]

I've just bought an 8800GT graphics card, and am rebuilding my computer, but it won't boot. This is my setup:

AMD 3800+ CPU
Inno3d 8800GT
2gb RAM
450w PSU
MSI K8N Neo4 motherboard

I've got dual-boot for Vista and XP. I can get to BIOS and everything fine, and select which OS I want to boot with, but Vista has a BSOD just as it starts the loading bar, and this was also the case for XP. However XP (but not Vista) booted into safe mode.

I identified the error on the XP BSOD - STOP: 0x0000007E - and, following some advice on Microsoft's website, selectively removed and replaced some drivers, eventually identifying that removing intelppm.sys meant that I could boot XP properly (although there are still some driver issues to be dealt with...).

However, Vista is still not working at all. I tried deleting the same driver, intelppm.sys, but this had no effect... so now I'm stuck. I can't identify the error from the Vista BSOD, because it reboots too quickly, and I can't set it to not reboot like that from the F8 menu because I can't reach that menu since it automatically goes to the safe mode menu (without the no reboot option).... When I boot Vista in safe mode it reboots on crcdisk.sys.

Any help would be greatly appreciated.

Can you boot off of Vista's cd to get to the repair console?
And did the problem arise just after you installed the 8800GT? Did you use the driver cleaner app to "prep" your box? If not, maybe try putting the old vid card back in and seeing if Vista boots then.

Yes I can boot off the Vista CD, and I ran Startup Repair, but it said that it couldn't do anything.. I might just reinstall vista.

If you still have the old card, re-install it, uninstall the drivers in Vista (use one of the driver cleaning utilities!) THEN install your new card. Granted you can usually get away with putting a new video card in without uninstalling the old one, but sometimes Windows pukes on you. So is life.

Well I reinstalled Vista and it's all fine. Thanks anyway!
