I should start by saying I'm pretty clueless when it comes to computers, just read half way through the re-boot thread until I realised what is was about.
Anyway, I got quite an old PC (5 years), which was quite good at the time, Pentium 4 and 256 something.
From time to time I run ccleaner and the disc defragmenter is running now. My C drive has 72% free space, someone mentioned to me before using too much memory would make it slower.
Is it time I burned all the porn and music onto CD and erase them from the disc? Or how can I find out what takes up all the space, couldn't be games or all those nifty programs from the net I might get around to using one day, could it?
