As title suggests, the damn thing will turn off whilst i'm on the internet.

Please help before I throw the computer out of the nearest window!!

cheers...

Could be many things Jon.

First, check your power settings. make sure the pc isnt set to turn itself off after any inactivity.

Secondly, check for viruses. a couple of the major viruses that were going around a few months back actually restarted your machine.

if its none of the above then you might want to check power supply is connected properly to your disks, you may have a loose connection.

Definitely agree with this - sounds like virus activity, though if you are infected with one of the later viruses surrounding the recent MS vulnerabilities, you wouldn't just be rebooting when the machine is online - I think the reboots are random and very very frequent!

Sounds like the sasser if its started recently.
Patch it up, i think its patch MS04-11, oh and make sure ur virus checker is up to date.

Along the virus theme...

Are you getting a system message before the machine shuts down?
A few of the recent virii give you 60second shutdown warning. They seem to be triggered by online activity or antivirus start-up.

If you can:

1) Update your virus definitions
2) Disable System Restore (unless using Win2K)
3) Reboot in safe mode
4) Run anti-virus software to remove infection

The other possibility, your not with Telewests blueyonder broadband and using a particular USB cable modem which they supplied but I cant remember the make of it. A few people I know have had the problem that the computer shuts down without warning after approx 5mins of being on the net. Its due to a new software patch they rolled out recently, all the details will be on the Blueyonder support pages along with its fix.
