|@riider Yeah, I ran a Memtest which indicated hardware errors. I removed the bad stick and booted using only the other 2GB and saw no operational errors. The stick is most certainly bad.|
@Derek Good idea, hadn't thought of using an eraser. I'll do this anyway because it just seems like good sense to keep the contacts clean.
Here is the situation now.
I have 6GB running. (Dominator GT 2GB underclocked to 533mhz) with 4GB 533mhz. System runs without a hitch. Better than before really.
The problem occurs after shutdown.
When I try to restart the PC only the fans run. The keyboard doesn't initiate. Hard-drive light comes on stays on (no flickering) then goes off. Fans continue to run, no BIOS POST or beep. No video signal.
So, to get the system to boot. I have to remove the 4GB stick. Deactivate memory re-mapping. I put stick back in, boot works fine. Then I have to re-enable memory re-mapping. I have to do this while the system is running because (even with just the 2GB stick) when I enable or disable memory re-mapping the system shuts down.
