Simple: replace the RAM, file for an RMA, etc..  If there's no warranty
or the warranty has expired and you need brand recommendations for a new
purchase: Crucial is excellent, avoid Corsair at all costs.

There is no software-based RAM tester available for PC architecture that
can stress-test RAM 100% reliably.  Proper memory analysers are almost
always hardware and do a multitude of tests (hard and soft failures, ECC
analysis, voltage regulator stress tests, and thermal stress tests).

An old job of mine required me to use one of these on a daily basis,
testing for bad RAM from Sun IPC/IPX and UltraSparc boxes.
