My search for my system slowdown goes on...I've reformatted and still get this lag that has started me looking in the direction of possible defective RAM. Ran memtest86 which said I had 2 ECC correctable errors. What does this mean? Sorry, didn't know how to describe my mobo when starting on this forum, but if I had to guess, I'd say Bus clock 133mhz, BIOS: Phoenix 6.00 PG 4/21/05 (I get the specs for my machine from my Belarc Advisor where they call it Main Circuit Board). Thanks.
