Thanks a lot guys, just the sort of info I was looking for, gonna have the electrics checked out soon and as of payday (this friday) im hoping to buy myself a nice UPS.

Just to clear something up, im not sure if the last spike was caused by my mums hoover, allthough it happened at the exact same time she unplugged the hoover she has used the hoover many times without the computer going off, infact this is the first time something has actually happened at the same time the comp has gone off, normally its random. So I dont think it is related though I thought I would mention it due to them happening at the same time.

Now another question...
I hadnt thought of the monitor, would it be possible to run 2 ups? one for the monitor and one for the PC? just a thought as this would no doubt increase the uptime for both in the event of a power cut. or Would it be better to have Just one bigger unit?

EDIT: according to that site I was reccomended the APC BACK-UPS 650VA 230V
