Problems booting up

Hi all

Just recently when I try to boot up I end up with a black screen. If I manually power down and restart I get the "Windows did not start properly last time" screen. If I go to last known good configuration the PC will boot up OK from there.

Any ideas on what might be going on please?

XP Home SP 2 with all updates.
2.53 Pentium
512 RAM
60 gig HD
256mb RADEON 9600 Pro Graphics card.

The PC is 3 years old and so far been very reliable. Model is an ADVENT 3112 if this helps at all.

Cheers all

 

Try clearing the cmos, unplug power supply, pull mother board battery out for a few minutes, reinstall. Will have to reset time and date. ed
