Is this a virus/malware problem?

I am getting strange problem on my pc today. The mouse stops working suddenly twice or thrice and each time i have to plug out and in .
My internet connection is also automatically disconecting and my pc running a bit slow.
Is it hardware problem or virus attack on my system.
I scanned my system with avast and mbam and they found nothing neither did hitman pro

 

Have you added any software recently?
Anything new in your startup entries?

 

nopes

 

I would try a system restore...

 

You can try MS fix It,Just find what best fits your problem and run it.Its a handy little tool and works pretty good if it finds a problem.

 

Sounds like hardware problem. Possible causes include:-

a. RAM module(s) showing signs of failure.
b. Motherboard/Graphics card -- capacitors : look at the top for breakage (You would have heard a very loud noise if this had occurred).
c. HDD -- chkdsk
d. Power supply unit.

Let us know when & what problem was when solved. All the best.

 

seems its correct by itself
now no problem
