Hi all, I've got hold of an IBM A22e thinkpad which as xp pro on. I formatted the HD and reinstalled all up to date drivers and every thing seemed OK but every so often it freezes and when you reboot it says can't find HD so if you reboot it says can't find operating system but eventually after rebooting it all comes back. The last time it did it I shut it down and left it for 30 min then rebooted and it just came back up. As anyone come across this problem as it is driving me mad just when you think it's gone up it pops again. don't know if it's the mother board or some component. Would really like some help guys.
