|After switching PC on, I get usual brief DOS messages then the Windows flag with the pulsing bar underneath - but then, immediately before the next screen appears (the 'user log-in' screen), the PC switches off! I restart and this time I get the 'Windows did not start properly etc' screen where you can choose Safe Mode, or Start Normally or Last Known Good Configuration etc. If I choose Safe Mode, it does log in OK, and I can work happily for any length of time. But if I choose Stary Normally it once again shuts down just before we get the cursor and the log-in screen.|
Whilst in Safe mode I've run 'msconfig' and disabled Startup items - no change, then re-enabled them - no change.
Having read elsewhere that the ATX power supply may be faulty, I've just replaced it with a new one but, frustratingly, it still responds exactly as above. I've had a look at the BIOS settings but am not really sure what to change to see if I can solve this.
My next option will be to re-install Windows XP, although I'm hoping to find the solution before doing this!
Is there anything else I can try?
