Weird Memory problem on old Dell.

[TheSpy007]

So i upgraded my moms computer to the maximum memory, 768mb. It froze once in xp so i ran memtest. 20 minutes into the test i got tons of errors. So i thought to myself ok 1 of the sticks is bad. So i tested each stick and got no errors. The chipset is i440BX so i cant find much into on it about ram. All 3 slots are used on this dell. You guys have any ideas?

Dust in the unused (until recently) memory slot...?

Try to clean it, and re-insert the module.
