Hi all, I recently bought a new MSI 9800gtx+ card to replace my old one. Stupidly (I now realise) I didn't uninstall the drivers from the old card before replacing it (I thought my BIOS would recognise the change and ignore it). When I tried booting I got a blank screen (monitor on standby- no display/bios/post). After re-seating to check it was in right and still no joy, I replaced my old card so I could uninstall the drivers before trying again. However, when I tried to boot Windows through GRUB (I have an XP/Ubuntu dual boot) it gave me an error message: Grub Error 13: "Invalid or unsupported executable format" I could still boot to Ubuntu, but after messing around with the Super Grub Disk (with little idea what i was doing) I stil can't get XP to boot. I'm going to use the Recovery console to try and repair the boot loader (?) for XP, but can't work out why this would happen in the first place- I thought a graphics card change was relatively simple, and wouldnt mess my computer up this much. Thinking back, a similar thing happened to my XP when I replaced the motherboard, does this suggest problems with my HDD or other hardware or am I just extraordinarily clumsy/unlucky? And any ideas why the new graphics card didn't work in the first place? Sorry for such a long post, it's more like 3 questions in 1! Thanks, Robin.
