I recently had a problem with what I thought was a new graphics card. I installed it and used it for a while and all was ok until I suddenly had my PC booting up, geting to the WinXP loading screen but then instantly reboots?
I removed the card and drivers and reinstalled and tested again but still no joy.
In the end I recovered WinmXP from my recovery CD and all was ok again.
Because this was an old version of XP it required a lot of updates so I left it running. I installed them and the minute I rebooted it started the same problem again.
This means that one of the numerous updates I installed is responsible, and I am going to reinstall WinXP again and install each update 1 by 1 until I find the guilty culprit...
Before I go down this LONG road, has anyone else had this, or know a resolve??
