I had a problem with burning DVD's and it turned out to be the power 
supply.  The voltage was at the lower limit as measured with a volt 
meter but when burning DVD's would go below the required voltage.  It 
was a pretty new power supply.  A new drive didn't fix the problem.

The BIOS and sensor both said the supply was within spec but using a 
Fluke showed otherwise.

Something to check.
