Recent Notable Laptop events
-Yesterday my laptop power just cut off unexpectedly so i thought nothing of it (it is an old laptop that overheats a lot),
-except today when i turned on my laptop i had found out that somehow a program had installed itself onto my laptop (i'm using Kaspersky internet security) The program turned out to be an extension for google chrome that added adverts to all websites. Luckily i had adblock turned on so when chrome was started my laptop didn't get any other uninvited visitors.
-Anyway after uninstalling and disinfecting my computer the laptop's graphics card just stopped working.(i am assuming it was the graphics card i have no proof but the windows pop up boxes i received was leaning towards the possibility that that had happened, It kept saying graphics something or other has stopped working)
-then when i rebooted my laptop there was some kind of proxy disconnecting me from the internet. Whenever i turned on any program witch required internet access it wouldn't connect although my router and internet was all fine and working.
-after trying to reset some of my settings i decided to roll back a couple of days to a point where this malware wasn't infected on my laptop.
USB issues started to arise
the virus is gone and all traces of it has been eradicated (or at least i think so) and my mouse and external hard drive etc was working fine until i moved my laptop. I didn't drop it or hit it i gently placed it on my desk then placed my keyboard (piano/keyboard) where my laptop was and moved my laptop to a bed side table. shortlly after i moved it i started plugging in my USB devices and after i placed in my mouse all my USB devices stopped receiving power.
Solutions i have tried
-i have tried to scan for hardware changes in the device manager and that hasn't worked
-I had also tried uninstalling my USB device controllers and restarting my laptop but that hasn't worked either

What happens if you unplug all of your USB devices and add them one by one again? You mentioned that they received power until you plug the mouse in, what if you plug the mouse in first?
I'm working with the idea that it's a power issue, and perhaps you are adding too many USB devices at one time which is causing the issues. It would also be an idea to try and find out why the power went out on the laptop in the first place. Go to the full post
