G550, MSI-board and WinXP: major problems

[edwarez]

Config: MSI K7T266 Pro2, Bios 3.60, Via-drivers 4.42, Win XP SP1.
Matrox-drivers 4.72.

Big problems here...
System get distorded now and then... suddenly horizontal lines appear in my screen and i have to reboot WinXp.

Installation-sequence:
installed xp
installed the automatic windows updates
installed via 4in1 driver
install matrox driver from original cd (microsoft certified driver version 5.72.021)

Set Bios to options suggested by matrox: pnp os to no and aperture size to 256.

Problem seems to appear on Via-based-mobo's. No IRQ-conflicts here.

Any suggestions??

Am so desperate...

Do you have adequite case cooling?

I have a Via based board (Abit KT7A Raid)and i have no problems with my G550.
Putting a small fan on the heatsink tho (a 486 fan or the such) is highly recommended.
I touched the heatsink while the PC was in Unreal 2k3 and i won't do it again. It burnt. With the fan, i feel happier that it will last more than a year. I really don't see why there isn't one as standard, except for the cost in bulk production.....

how do you go about with such an operation.....
especially for an amateur like myself....
