I'm having some real problems with my laptop at the moment and I would really appreciate some help.
I'm going to try and keep it to the point, but these are the problems I've noticed.
I first spotted any issue whilst using traktor dj software last Friday. After an hour of use the computer wouldn't load the next track and hung for about a minute even though the program was running and sound was playing.
I then noticed I would suddenly get random slow downs in any program trying to do anything. All i would get is a blue spinny wheel and a minutes wait for it to do anything. This could be web browing, using musicbee etc. I also noticed that getting into control panel would take about 4 minutes etc etc. Once it had cleared the computer goes back to being as fast as it ever was. I also got a java .dll error, but reinstalling java was taking about 40 minutes (is that normal?) so I gave up. I also noticed at one point that I couldn't copy text in chrome without it crashing the page.
I cant hear the hard drive over working, and the cpu and ram were running normally, and no processes were taking up all system resources.
I decided to try and use a restore, but I had only one restore point from before Friday, and when I tried to use it the computer had a critical failure. Unfortunately I didn't get a screen shot in time before I BSOD'd.
On startup from here I got repeated BSOD after about 3 minutes of windows being logged in.
I have managed to restore to another restore point, and at present the system is stable, apart from the random hangs.
So far I have:
Tried restore - failed
Run checkdisk - no issues
Run Malwarebytes - clean
Run AVG - clean
Cleared all temp files and recycle bin etc.
Run sfc -scannow which tells me some files cannot be repaired....
I don't remember when I ran CCleaner, but I have since read that the ccleaner registry cleaner is not needed with win 7 and can cause issues. Can this be what I've done?
Any advice on how to troubleshoot this would be massively appreciated.*

Thank you in advance for any help.
