I'm fighting with problems with my computer (lenovo G780 on windows 764bit) for some time, and till now nothing helped. So I was hoping you guys can help me.
So in general, About 2 weeks ago i decided to clean my Windows after few years of using. I reinstalled it, as well with other programs and games I'm using. But from this moment some weird things have started.
- First of all the computer is working slower than before reinstallation.
- Secondly my antivir Avast premier is turning it self off, I mean its working in background but saying that im not secured and fire wall is turned off, I can turn it on but after some time its same story.
- Thirdly, right now I see that after I turn on the computer, and before i start using any kind of program, the svchost process is using more than 1 500 000 Kb of memory.
- another thing is that windows update cannot install new updates. It download them, install and after reboot when it try to configure them it shows info, that it cannot be done and restart computer without upling the updates.
I was thinking it some problem with HDD so i tryed to run CHKDSK but it was unsuccesfull. So I removed the disk and went for another computer to do it from another windows instance. It was possible without any problems. Windows corrected all errors. I defragmented disk and serched for bad sectors, but everything was fine.
Till now I tried to scan computer with avast (it cannot find anything and the avast cleanup scan stops at 99% and cannot move further regardless how much I will wait for it). Tried as well microsoft security essentials but it didn't found nothing. Downloaded Malwarebytes and scanned computer without any result.
I used even Webroot SecureAnywhere Endpoint Protectiona at my work, this one actually founded some infected files and removed them with success. But it didn't helped, computer is still slow and not working correctly.
I'm not sure what should I do now as its kind annoying to work on it, and I have no idea what should i do next.
