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.
