Well, the weird thing is, it was giving a LOT more errors, spread across a LOT of different parts of the memory, when I tested it with the sticks in the positions I originally had them in. I pulled them all out, and put them all back in with the older pair now where the newer pair had been and vice versa, ran the test again, and got WAY less error addresses in it. In fact, in that last test, ONLY one memory address gave an error. I tried to post a picture of the last test from the previous instance, and the last picture from the newer test.... but the forum software said the file was too big, even when I tried sticking it in a zip file.
Anyway, the machine just crashed again, so posting a new minidump.
On a different note, for some reason, sometimes at startup, one of my chat programs, Pidgin, shows up with all the interface showing complete gibberish, as in the type-font looks like it got replaced with complete junk, and some other file-explore windows then show blank white instead of the file names. 0o Exiting out of Pidgin and relaunching it usually sorts it, but this is another apparent symptom of whatever malfunction is going on. On the other hand, this time, on relaunching Pidgin, everything showed up with [][][][][] in it. 0O
Edit: Annnd, BlueScreenView is showing me blank white space instead of readout. And Paint.net is missing parts of its interface, too. Bah!
