Maybe it's time to restore it to the factory issue and if there is no hardware issue then it will be just as fast as it was back then.
Maybe you wanted more but the clues are not here. For example if you had written "I use Norton and TeaTimer" I would note the issue with that.
I've an acer aspire timelineX5830TG laptop.
It has been behaving very slow and sluggish for over a couple of weeks now. Opening a folder takes ages. Videos get stuck. I've never seen this machine that slow.
I'd installed ESET NOD32. Ran an deep system scan. didn't find anything. installed and ran a full scan with malwarebytes same result. I thought it could be some virus that antivirus won't detect. Got the OS reinstalled. Same issue again!
Some one help please!!
