POL Viewer issueFollow

Recently upgraded motherboard, cpu, and graphics card. Reinstalled POL, FFXI, RoZ, and CoP today. Ran POL, got the 71 file update to the most recent version (right after POL maint. was completed), then reset.
Viewer gets odd video artifact flickers, then if I don't shut it down soon enough, it freezes my computer altogether. The glitches didn't occur before I updated, so it doesn't appear to be a driver issue (got the most recent ones anyway, as I just bought the card today, mobo friday). ATI Radeon 9550 (256mb), MSI k8mm-v, athlon 64 3000...otherwise no hardware is different.
So...I can't quite figure out what the issue is. A friend of mine said her viewer, after the most recent update, has no issues. Mine, I can't even get to the point to log on to update ffxi after the reinstall (got a few k files before it froze the first time, now it lasts ~30s, if that).

Ideas? .___.;

Tried running the ffxi bench, 3dmark bench, and my computer locks up or the program crashes on both. Went and got directx9, most recent drivers ATI has for download, and still nothing. MSI doesn't appear to have anything I can readily find about the mobo or card

There's something I'm missing here, and it's starting to infuriate me.

While thinking, this occurred to me. I was getting odd graphics artifacts on both my old radeon and the new one as well (although the new one only did it on accelerated graphics related things). However, before I bought the new card to replace the glitchy older one, I was running on the mobo's onboard VGA with no ill effects.

Now the question is might it be something with the mobo's AGP slot.
I may try testing the new card in my old mobo tomorrow to try and isolate the problems further. Iunno though .__.;
