A pc I am working on ran great till 20 minutes ago, when the following happened:
I insterted a usb flash drive with a file and tried to search something on the internet when I noticed the mouse cursor was moving with lag spikes. My first thought was that either the CPU was overworking or the ram was getting full. So I restarted the PC.
Instead of the PC opening, it played a rapid sound (faster than when there is no ram on) and I started checking all the things connected to it, only to find out that when the usb keyboard gets connected this sound starts. If I connect a keyboard with no usb gate but the original circle purple one it makes no sound.
BSOD also appeared with a BAD POOL HEADER error.
What do you think is the cause?
P.s. there were 4 or 5 current shortcuts today, but I don't know if these are connected to it.
Update: A friend of mine accidentaly fixed it when he inserted 2 keyboards. Now the issue happens only when you put the old keyboard or another one that propably does not work. Still don't know why.

Is the problem occurring when the flash drive is inserted? – Scorpion99 – 2016-03-03T12:20:30.647
I removed the flash drive when the PC was having the above lag spikes. Now I have deleted it contents and I have given the usb flash drive back. The error keeps happening, it seems hardware-ish. So what exactly is your thought? – Lev – 2016-03-03T12:25:44.103
It could be a problem with the powersupply. The USB stick needs additional power to run which is the symptom. I would advise to turn off the pc, unplug the powercord, press and hold the powerbutton for 5 seconds with the cord unplugged (to ensure that all power is out of the system) then plug the cord back in and see if the issue still remains. – LPChip – 2016-03-03T12:35:09.123
