Mainboard is a k7sem rev. 3.00C with firm mounted 1.3Ghz Duron with 512MB PC133 SDR
Video is a Apollo Bloody Monster 3 with a GeForce FX 5600 256DDR
Monitor: Toshiba Tekbright 710V (also tested a Phillips 109B)
System is Win 98SE
Note: Bios, mainboard chipset drivers, video card dricers, Monitor and OS have all been updated to the latest I can find.
Problem: Onboard video worked no problem. After installing the video card the system is tweaky. On bootup it sometimes gives a black screen for windows. Other times it gives a fatal exception 0e at 0357:00006747. The system is more stable with the adapter refresh at default. Vid settings can not be changed from 640x480 @ 16 colors and this problem occurs in both pci and agp modes. Sis Sandra utility shows 4x function for the AGP slot. Irq is 5 same as the sound card and ACPI IRQ Holder for PCI IRQ steering, rhough no conflicts are found with device manager. Even though the sound card is 2 slots down, I pulled the sound card and tested for resolution and found it still failed with using onboard sound..Any help/ ideas would be much appreciated.

The 5600 is a 4X 8X card and the SiS AGP slot at 2X 4X may not deliver enough current at default settings to power the card correctly. If you have a BIOS setting that will let you adjust AGP drive force manually (Some motherboards do)try different Hex values in manual mode starting with aggressive settings such as DA or DB. If that works well try scaleing back to C9 or C5 and so on until you find a good setting for the best performance and stability. More on the subject is at http://hardwarehell.com/discus/messages/1674/1676.html?1012453209 it deals with VIA chipset mainboards but the principle applies to the SiS chipset as well.
