Anyway - good luck Alvin, sounds like CPU, memory or video aren't the issues for you, and I don't understand why I had to reset my bios to get the stupid board to accept a new video card - these boards seem temperamental!

If the bios is set to AGP and you put in a PCI card, it may not look for a pci card automatically, if you put in a AGP card and it was a pci card, same problem.

Resetting the bios forces the bios to re evaluate the hardware when you switch it on, thereby getting it to use the right video card.

Pleasure to help out. I just hope your tabor3 board lasts a lot longer than mine did (about 2 years only)... :-(

I do however have another motherboard that i bought and can't even get it to turn on...No light on keyboard or motherboard, no fan movement.
The motherboard is called Biostar M7TDR P4...Socket 423
I used one stick of 512 mb 100 mhz memory like the manual siad.It siad 64 to 512 in each slot up to 1.5gb......
But when you turn it on nothing happing.
I used the same power supply I had my last P4 mother board in. it has all the power connection. ATX...The extra 12v connection and the extra 5V connection for CPU.
Nothing is happing. it doesn't even start.
I even took Cmos Bat. out for an hour to reset Cmos.
I have move Cmos jumper to pin 1-2.....and 2-3( Normal and clear)
it is suppose to be a band new board.
Any help would be great.
Thank Alvin

Yes, I bet when they test these motherboards at the shop the Bio is set up for that hardware, so when you get it home and put your hardware in it doesn't work...I think that when they sell Motherboards they should put that in a note to first take bat. out to reset Bios.
Thank Mr. NooNoo
