Hello, My old motherboard was limiting the performance of my computer and as such my partner and I decided to buy a new motherboard, which supported 8x AGP (for our 8x AGP Graphics card) and DDR Ram. Having installed everything properly, all seems to work fine: the Graphics card is detected, the processor type and speed are detected properly, the new DDR Ram is detected properly, as are all the drives. Windows should boot... but it doesn't. Instead there is a blue screen telling me that boot-up has been stopped to prevent damaging the computer, and to check for viruses/disconnect any newly installed drives before continuing. Is this a drivers problem? a conflict caused by the new motherboard? Or is thewre a BIOS setting i have missed (I have tried the fail-safe defaults and the optimised defaults both to no avail)? Everything comes back to this blue screen... would formatting and re-installing windows and all drivers help? Thanks in advance for any help, anything is appreciated, and we'll be very grateful for any response!

Ok, you violated the first rule of XP. it hates system changes. You'll have to re-register with Microsoft since it thinks you've installed it on a different computer and are in possible copyright violation. You 'll have to backup anything you want to keep, use FDisk to delete all partitions then create a non-dos partition for the OS. Then do a clean XP install and load whatever MB drivers than may have come with it. Then reinstall any applications you have.
