AGP drivers out of date?

This morning when logging into SL I got a message saying my AGP drivers were out of date. I went to the technical support faq and followed the directions there, finally three hours later I found my motherboard on the manufacturers home website. downloading a 4-1 driver I located in the listing of my motherboard, I then installed it, and restarted my computer.
When I ran SL after the restart the game started up fine, without any error messages and seemed to run normally then about twenty minutes in my computer came to a complete halt, forcing me to shut it down. I restarted once again after listening to some irregular beep codes which I have no decrpytion for and tried again, this time my computer came to a halt after only two or three minutes.
Am I missing something, Is there a way to find the drivers I need? Did I install them improperly by just running the 4in1 exe?

the motherboard is a KT400 Dragon ultra, made by Soyo.
heres the info the WCPUID gave me
Manufacturer - (non)
Product String - KT400-8235
Version String - (non)

any help would be greatly appreciated.

Well luckily the crashing doesnt seem to have been a problem with my agp drivers, and I still have no idea what I changed as I installed the same drivers that were included with my motherboard. The crashing seems to have been a issue with a ZHAO animation overrider, taking it off stopped the crashes. no idea what its deal is but I can easily drop it

Yes Nines, same here, the crashes are object/attachement related. It can happen by clicking on one, editing one or wearing one. Wearing my ao makes me crash every 30 sec.
I crash randomly every 15/30 min. This after a reformat, fresh install and all new drivers, so basicly dont bother this is something in SL that isnt fixed.

For your AGP and chipset drivers, Nines, go to www.sis.com, click 'Downloads', on the right of the screen you will see 'Identify your sis products', it will scan your pc and give you all the drivers you need. I did but it didn't help the crashing tho.

I hope there is soon a fix for this, i'm about to give up on Second Life forever.

thanks for the reply, I tried the sis site though it wasnt of any help, it said my agp driver was provided by the board maker, which it might be but I have no clue where to go.

on another note, in game i had removed all attachments and was just moaping around in the build mode when I crashed again, so it could be a problem with my agp drivers, but I dont know what to do about it anymore. maybe I'll go wander around soyo's cryptic site and see if I cant get some luck. =(

After crashing over and over while doing simple things like choosing colors on the palette while making clothes, or just opening my inventory I managed to get another error screen about ati2dvag.dll going into a looping error.
I searched this up and came up with a fix that seems to work as I havent crashed yet
so for anyone else who might have gotten the AGP error you might try this

Right click-mouse over My Computer
Properties
Hardware(Tab)
Device Manager(button)
Click [+] next to System devices
right-mouse on CPU to AGP Controller (or whatever your controller is called, mine was SiS AGP)
Update Driver(button) {this didnt work, said I had the latest driver}

Select Install from a list or specific location (Advanced)
Next(button)
Select Don't search. I will choose the driver to install.
Next(button)
Select PCI standard PCI-to-PCI bridge
Next(button)
Finish(button)
Reboot.
