Gah...my laptop is still broken and its not even put in the shop yet..Its either just that I was bringing into uni without a proper laptop back and it got damaged, or more likely, the fact that it got tea spilt over it in uni...
Its got some kind of hardware problem, I think the RAM like last time, but not sure..
1st May: Yay! I got my laptop back a few days ago and it was indeed a problem with the RAM again. It cost me £85 to get a new stick put in now, and its working fine. I was a bit worried at first because it actually smelled of burning plastic, but that was probably just some initial crap inside, as it doesnt do that so much now.
Hopefully I'll be posting some more now! I've got my final exam for first year on the 4th of May..,that doesn't seem so far away now :'(
