Now this morning it's freezing up again, this time there is no buzzing though. I turn it on, and about 15-20 seconds after being on the desktop it freezes. When it freezes the lazer light on the mouse goes out like it's not plugged in. Also a few times when it has frozen this morning there has been weird coloured pixels appearing across the top of the screen (this does not happen every time though). I've tried leaving it and turning it back on etc but it seems like it's not going to help this time.
I did have an issue with over heating 2 months ago but we cleaned off the dust from the inside and have opened the side of the case to help the air go through it and have not had any issues with it since doing this.
If anyone could help with what this might be that would be great.
*EDIT*
I can start the computer in safe mode and it doesn't freeze up. I'm not sure if this helps to work out what is causing the issue or not but thought it might be worth noting.
Also it just now did the buzzing sounds as soon as I hit the power button
