yeah... they are in the blue sockets; i read the manual before i built my computer (most of it lol)

And you have the same problem just using one stick in DIMM_B1?

And you've tried each stick alone in DIMM_B1?

Just trying to troubleshoot piece by piece.

alright ill try it

yeah that didnt help lol

im going to put both of them back in...

Did you reinstall XP (assuming XP) after changing the hardware?

In order to force error messages you might try these steps:

rt. click My Computer then click Properties then Advanced then Startup and Recovery Settings then unclick Automatically restart

Also: look in your Event viewer: rt. click My Computer then click Manage then Event Viewer.
Or: Administrative Tools/Event Viewer or Start/Run/ eventvwr
Open the system as well as the application tabs & look for X errors. Click error line for details.
Post back the source & event id & Description especially of errors that seem to coincide with this issue.
Also check the Information lines that might coincide with this issue.
