Midge, you're back! Err... hello!

Anyway weird but good news everyone... we're back to how it was before, it is the PSU that's broken. The same guy came round earlier with another computer and a different power supply to try and test whether it was the CPU or mobo which was broken. However he tried running my motherboard off this different PSU and this time it worked... the other one he tried must've been coincidentally broken or not compatible with my computer.

So I'll get a new PSU tomorrow or whenever, don't really want to spend loads on some £60 modular one, trying to save for Uni, probs just get one similar to my current one.
