My 5 year old DELL is running slow and a few applications (e.g. games like Company of Heroes) hang for no apparent reason. I've run system scans (Norton 360), used CCleaner, Disk Defragmenter, and deleted a lot of unused games and applications from the hard drive but still no joy. I bought 4GB of RAM thinking that lack of memory (it was 1 GB) might be the issue but still no joy. My graphics card is a Radeon X800 which handles most things well.
So I think I've ruled out a virus/malware, registry issues, memory capacity and I've cleaned up the hard drive so whats left to do?
BTW as I sit here typing this with only IE running, the pc appears to be working away at what I don't know. The hard drive is also showing that I have only 53% of usable space left even after deleting a load of stuff. Is the pc just showing its age or is there something else I should have done? I was toying with the idea of upgrading this pc (new mobo, graphics card etc)but would it be cheaper to build a new one from scratch?
