- What update was causing this problem the first time?
- Do you know what updates are the ones that XP "decided to update"? The same as the first one?
- What lights should be lighting up on the "wireless box"? When? Why?
Anyway, if you turn the PC on something should happen (the BIOS doing it's startup things) without involving anything related to Windows. So whatever Windows does with updates and drivers shouldn't influence that. So it's not a Windows issue, but a BIOS or hardware issue. Seems like a job for the repair shop.
I have an HP media centre PC with XP and Mcafee security, the other day after an update the display went all funny and got a message up for a second saying something like display not operating normaly, i thought it must have been the graphics card so i removed it and took it to local shop to replace, she told me it was probably caused by a driver error caused by the update, so i went back and refitted the card and tried again, at first the PC wouldnt turn on fully, the lights and fan came on but no action at the monitor, i turned it on and off several times and it eventually came on with a dodgy hardly readable screen, managed to reset to an earlier date and it ran fine the hole day, when i came to turn it off it decided to update, never thought anything about it, but the next morning im back to it not turning on at all now, no mater how many times i turn it off and on, i just get the lights and fan, and another thing i have noticed is that the wireless box isn't lighting up, any ideas orhelp would be much appreciated, thanks.
