Did a search here and on Google; Google so far has been no help. Sorry for the impending wall of text, I'll try to keep it simple.
Computer gets left alone, screen goes into screensaver mode.
Computer gets woke up after X amount of minutes.
I get a BSOD,it does a memory dump and shuts down within 10 seconds.
It restarts automatically to run a CHKDSK scan, goes through the process and reboots.
Computer is sluggish, but runs...
Today, I go thru the same cycle as aforementioned except that now on restart, I get an error.

Your copy of Windows is not genuine.
Download malwarebytes, run a scan for 2.5 hours. Turns up nothing.
Run Avast for roughly the same amount of time, again - nothing.
Did some reading on Google, so far it's saying the only thing to do is to re-install Windows but I don't have a disk; Win7 was preinstalled. Yes, I know, shoulda made the backup when prompted.
Can any of you tell me what the ho-ho-hell is going on?
ETA: laptop is roughly 2 years old....
ETA2: is it still safe to do online banking as it is? Avast is still running but other inquiring minds in the family want to know for sure...
