Had to search for a moment to find anything about the mainboard, but it seems that it has a VIA chipset which I suspected from the 'V' in the name (VIA Apollo Pro133, that's 693A/596B.)
You definitely need the VIA 4in1 drivers, especially for proper AGP support. A short search suggests you could try the 4.33 drivers.

Of course your system could have other problems. PC66 RAM with a P3 650 sounds funny, the CPU should run with FSB100. That's a possible reason for crashes. And bad caps can always cause issues with old systems.
But if you didn't already install the 4in1 drivers I'd try that first.

Ask old hardware and driver questions in Marvin. This forum is for Windows games.

Yes check for bulgy or leaky capacitors.
I had a Soyo SY-7VBA133U motherboard and the first indication I had that the motherboard's caps were going bad was crashes and general instability.

Thanks , I found the mb drivers on a stash of driver cds, I could not find it at first because I have like 10 soyo drivers discs and they all look the same, but I think I'm gonna switch this motherboard for one of my Aopens with Intel chipset as Phil suggested me.

I already replaced the RAM for a pair of 256mb pc133 chips, if I remeber correctly the max amount of ram supported by Windows 98 Se is 512 right? wil it recognize more if install the unnoficial Service pack 3?

Moved to Marvin.

The service pack 3 sorta works alright with 1gb ram, last i tried. I personally don't use it so its been awhile. But honestly, for games that came out before 2001 512mb is godly. You will see no real good performance boost in both games or windows. Especially with a 650mhz Pentium 3.
