Windows 7 very slow start up and sluggish general performance
Hi all,
My Lenovo G570 (i5, 4GB ram) running on Windows 7 Home Premium had been running great up until last night...
It's now booting up really slowly and once it eventually has booted up it runs very slowly too (everything seems to be in slow motion i.e. if I click "computer" it opens up very slowly, almost like it's stuttering). I also can't play audio / video files (the files open but playback is broken / chopped up).
I've also noticed that one of my USB ports is no longer working (external hard drive lights up for a second when I plug it in, but then goes off and the drive is not recognised).
Browsing the net (Chrome) seems to be fine though, streaming audio and video is ok.
I've tried disabling all start up options when booting up, booting in Safe Mode with Networking, CHKDSK, virus scan, malewarebytes scan and a system restore to a few days ago but haven't had any joy.
I'm hoping someone on here might have a few suggestions for me to try.
Thanks!
