FIC VA-501 mainboard socket 7. AT style motherboard. AMD K5 133, Cyrix 6X86 200 and Intel Pentium P55C 233 compatible [highest rated cpu's without board modifications]. Boy that's an old one. Isn't even listed as an active motherboard on the FIC site [I do find references to it here and there but no manual only a PDF cpu compatibility chart]. I doubt it meets Windows 98 minimum requirements including minimum memory which is probably why it shuts off.

i have a p166, 128 mb ram(no sdram). network-pci-card is now at first slot. i installed internet. customer tried using usb-card! and network-card. he is not expert. thats why it crashed. maybe there is more than this. i changed the board because it could not recognize cd-rom. a working 2x-isa-card-cd-rom was exchanged by a 24x. i asked the question already. probably bus-driver needed, noide deleting in registry(i did not do it yet on the older socket 7-board.

Hi Michael,

I use the following pattern for loading cards into motherboards.

The video card ALWAYS goes into the first PCI slot.
This is the slot at the top of a tower case, or at the far left when looking at the back of a desktop case.

IfI have the room, I leave the next slot open.

I try to avoid using either of the side by side PCI / ISA slots. Many times, their are conflicts when you use these slots.
Also, on many motherboards, you cannot use both slots at the same time.

If I am using an ISA sound card, I install it in the last ISA slot.
The slot closest to the edge of the motherboard.

I also try to leave an empty slot on both sides of a modem.
(This is to reduce the risk of damage when the phone line gets a lightning strike)

Sounds like you may also have a grounding problem. If the board is not grounded properly (by using the wrong mounting screws) or if the board components are making contact with the metal on the case, this can cause intermittant re-booting/shutting down issues. Double check this.

Good Luck.
