I am somewhat new to fixing my computer myself.
PROBLEM:
The mouse pointer sometimes stops for a moment and the screen freezes. During these freezing events 'ctrl+alt+del', 'Num Lock', 'Caps Lock' and 'Alt+Tab' don't work (LED's don't go on or off) and of course the mouse pointer doesn't work at all either. Also, when this freezing events happen and the computer unfreezes, there is a little red line hovering right besides the cursor at all times, till it freezes again. Oh yeah I forgot: Most of these problems happen while using Firefox, but even after I close Firefox the problem persists.
Aspects that I have checked already
I have checked all my drivers, which are up to date.
I have also scanned my computer with AVG and SuperAntiSpyware to make sure there isn't any viruses.
I accessed the BIOS to check core temperature and such, all good, running at around ~57degrees.
The computer is not overclocked and since it was recently formatted it has 380GB unused memory out of 465GB of memory...
