Thanks for the response. I've made no changes at all, hardware wise and no new programs for at least a month. Tonight, when I switched on I couldn't open any mail in LiveMail. I transferred a new CD onto my comp and was then updating my database when it the machine creashed.
I was updating my Music Collector Database, when it suddenly crashed. Never happened before in the 3 months that I have had the machine. It happened last night after I'd been on it around 1.5 hours.
The m/c is an acer all-in-one. after the BSOD I rebooted and the options menu (start in safe mode, with network, normal) came up, but I couldn't move the bar from the "normal" start. After the seconds counted don it restarted and since then I have had no further problems. It conected to the internet to check for updates on the fault but nothing came up.
As mentioned everything seems to be okay and yes, I can access google. I haven't tried safe mode.
