Okay, I have an old Sony Vaio, model PCV-RX951.

It has a P4 2.66GHz
Mobo _ Asus P4S533-VL with a BIOS still from 2002, but I can't find a new one???

1GB ram total

I recently updgrade the Video Card To:
nVidia GeForce7300GT - AGP 2/4 - wiht 512MB
I'm nearly positive that I have the most current Bios for it. Version 5.73.22.57.01

I have a Samsung 32" Monitor im using 1360x768


the vid card that came with the PC was very slow running this res on the new monitor, so i upgraded.

Well since then, I startup WoW and I get all this crazy artifacts, like lighitning bolts flashing across screen.

I have tried doing a complete repair of WoW, but it was working fine before.

I am using factory default vid settings, other than resolution.

The only thing i can think is maybe I need more Power. If I remember right, the stock one that came with the PC is only 300 watts. I had bought one, but it didn't work for this old PC.

The only think i'm havng problems on is WoW.

OH And this is wierd, So i was using a 32" Sony Display before, same problems. I switched to this Samsung today and now, when i start up WoW i get a massive lock-up and failure- causing the entire system to reboot???!!!

Please any suggestions? or ways to correct

That's a poor power supply.......just replace it.........k
