|Had a bit of a problem with our old computer. It booted up into the light blue Windows xp screen, with the logo but no text - it would just sit there and the mouse would work but nothing else would. I did a bit of reading and decided that some necessary system files might be corrupt.|
I put in the XP disc (the original one that came with the PC, set the BIOS to prioritise booting from the CD and booted from the CD. I was following this guide (http://pcsupport.about.com/od/operatingsystems/ss/instxprepair1_3.htm) and it all went fine until step 8. Once it had finished doing all that, it didn't progress to the screen in step 9, it just reboots then bootloops (trying to boot from the CD still, I think). I restarted, told the BIOS to boot from the HD but the same happened (bootlooping). Once, it gave me a blue screen error (0x0000007f (0x0000000d, 0x00000000, 0x00000000, 0x00000000), but it didn't happen again.
If I try to start in safe mode, it says "windows xp setup cannot run under safemode".
