Toshiba laptop won't boot

Running Windows Vista 32 on a Toshiba laptop (not sure of the model number).  Customer’s laptop won’t boot.  The cursor just flickers up in the left hand corner.  This usually indicates a hardware problem.  But he says it began when Kaspersky popped up and said there was a problem with a website.  A message from Windows said to reboot his computer.  After that every reboot, safe, normal mode, last good… nothing but the cursor flickering.  

He found his Toshiba/Vista restore disk and tried to boot from that.  He got to the boot menu and chose to boot from CD, but then it immediately went  to the flickering cursor.  

Why doesn’t it boot off the cd?  He can get to the bios setup and the boot menu. But it doesn’t load windows.

This was all done remotely, trying to talk him through it over the phone, which made diagnostics difficult.

Any ideas?

I would check 2 components - memory and HDD.
if you can, test memory modules. So if there is more than one, just try to start laptop with one, and then with another
remove HDD, put it into another working machine (as internal or external, it does not matter) and run check disk on it (chkdsk d: /f). Please note your drive letter can be different than D: in my example. Then put back to Toshiba and try to boot

Remove hard disk and attempt to boot from the CD.

If it still goes to the cursor like that then there is a major hardware problem on the motherboard.  If it boots satisfactorily then the hard disk is at fault.
