computer shutting down

[Stephen Lambert]

It could be many things and heres a couple:

A recent virus causes PC to shut down:

W32/Lovsan.worm.a is a Medium-On-Watch Internet Worm.
Also known as "Blaster" or "MSBlaster", Lovsan has
quickly infected computers throughout the Internet. The
worm takes advantage of a flaw in Windows NT, 2000 and XP
operating systems to drop a malicious program on your
computer. Taken from Macafee Antivirus website:
http://us.mcafee.com/virusInfo/default.asp?
id=helpCenter&hcName=lovsan

It could be that the heatsink has been dislodged in
transit and therefore not cooling you processor down.
This would hav the effect of shutting the PC down.

You may want to supply a bit more information as to when
this fault occurs so that we can narrow search for a
solution. Does it happen when in a certain program? Does
it happen after a set period of time? Do you get any
warning about the shutdown or any error messages?

Hope this helps

Thanks for your suggestions Stephen

I think that

could well be the problem
I did have a problem where the data ratios were changed
and that was fixed maybe not properly though?

may be a trip to the computer shop as the computer is
only a few weeks old

my antivirus is all up to date and i have downloaded the
fixes for blaster and sbigf alson and neither are on my
computer

thank you
