Bloody Computers!!

Flippin things! after my comp crashes a couple of weeks ago - its gone and done it again! im borrowing hubbys at the moment whilst he does a total hard drive sweep - seems i have picked up another bug which decided to start eating my system files!!! i wouldnt mind but i had so many anti virus things and firewall etc.. that it must be a nasty little bugger to get through all of that! so will mean a total pain of having to load up everything i had AGAIN!!!! not in the best of moods now as it's meant i've not been able to do anything on it all day!!!!!!
