New PC starting to slow down
I bought a new PC a few months back, all great for a while but now in the last couple of weeks it has started to slow down, web pages taking longer to load etc.
I have very fast broadband according to the checker, my ISP provider ran some checks and all appeared OK. I run AVG for anti virus (the paid for version) and also AVG Tune Up which tells me I am running at over 90% performance. I have tried running CCleaner but is just freezes, so no results.
My hard disk is only around 25% capacity and WinDirStat doesn't show anything unusual.
Any suggestions to speed the thing up? I only bought a new one because my previous 10 year old PC was slowing down.
Is there any software which can help?
