Well since I upgraded to XP and went 64AMD I've not had any of these.Last night I had 6 in a row and actually had to physically hold the stop button on my PC to get out of a start up,blue screen,start up loop.
I noted that the PC was a little warmer than usual and decided to leave it until this morning.It seemed ok and I did a thorough check through systems and hardware(after the error warning this morning from M$ help) and I can find nothing flagged.
Yesterday I did some maintainance with disk clean up,Win Optomiser Platinum 2,Adaware,Spybot.
I also had notification that ZAP needed upgrading which I also did.This then did a spyware scan of it's own.At this point Eset's NOD32 flagged a trojan which it deleted.
This morning I went to windows update(which funnily enough was the site I was trying to reach when this shutdown,blue screen loop began last night)and found that there was a driver for my Radeon 9700 pro card to download and install.
This morning I've had one program(Terragen which is a beta and a new upgrade so I'm not too alarmed) go to a black screen during a render.After that I've had one more blue screen.
I've been back to ZAP website because this has caused me problems before with a couple of bad upgrades but can find nothing flagged except for 64bit AMD processors but the problem wasn't one that had any bearing(summat about making sure DEP was working which it is).
I did install a Freecom 250 GB external hard drive about 2/3 weeks ago but I've had no problems with it.I also found about two weeks ago that the drivers for the Radeon Pro had become uninstalled/missing but downloaded them and everything was fine after that.The system had been roaring and straining which made me check the hardware and the drivers but it settled down after the reinstalled drivers).
So anyone got any ideas?It seems fine at the moment though I bet when I try to post this I'll get another blue screen.
