USB Related problem[Need help ASAP]

[Akash Beura]

Hello guys, i recently formatted my PC and installed VLC media player and Mozilla Firefox. (Downloaded fresh copy).
Now I have 2 users in windows.
1st one is "Sonu" and 2nd one is "Home"

Case 1: Logged on with user "Sonu"
When i open Mozilla firefox in Sonu then the USB continuously connects and disconnects with every movement i make with my mouse, also my USB Keyboard gets affected, like if I'm typing something(eg., home) then it tends to show problem like "hooooooooooooooo".
Also, When i open VLC media player and play something it runs well, but when i right click to view options then same problem arises(i.e., that connect disconnect problem).

Case 2: Logged on with user "Home" (currently using)
Here everything is same but in Mozilla I can open a few pages, also when I tried to login in tomshardware with facebook login that problem came up once again


What should I do? Is it a driver problem? or OS problem?

Previous copy of my windows didn't had that problem But I formatted more than 3 times to get that error free copy of windows. Is it my Windows 7 Disk problem?(Pirated one).
Or something else?

Hi,

Do you have any devices connected in to your USB ports other than the mouse and keyboard?

 

[Akash Beura]

No, I just have my USB Mouse and Keyboard connected, nothing else!

 

[trekzone]

Have you tried a different set of mouse and keyboard?

 

[Akash Beura]

Yeah! Same problem arises. Just checked with new Mouse. Plugged in all the USB ports(back and front) Same problem.
