Hello, further to my previous message, I now realise that my machine only boot hangs first thing in the morning, from a cold boot. First time you switch the PC on, it goes through POST, to the XP loading screen, does about 8 runs on the blue progress bar, then goes to a black screen and halts. After resetting, it works fine at all times thereafter. Any ideas?
