I purchased a second video card for my machine so that I could setup a 3 monitor system but I am experiencing an issue where the machine will constantly reboot. I see the post screen for a second or two and then the machine reboots. If I remove either of the cards, leaving the other in the machine, the video output is fine and the box boots into Windows as expected.
Both cards are NVidia. One is PCI-E and the other is PCI. I have tried switching between the primary cards in BIOS (either PCE or PCI-E) but that doesn't seem to help. Are there any other issues that I should be aware of that may cause this? Any advice on how to debug the issue?
EDIT: Way off on the video card before. It was actually the crappy one that came with the case. It is 500 watt with 1x 12v rail at 22A. I tried a 700 watt with 3x rails at 18A. It did the same thing.
- Motherboard: Biostar NF4-A9A
- PCI-E Video Card: NVidia GeForce 7600GS DDR
- PCI Video Card: NVidia GeForce 6200 DDR2
Just noticed the difference in DDR and DDR2. Is this the issue?
There are 2x 1GB sticks of memory in there. If I take 1 out the machine boots fine. I just bought 2 more sticks along with for a total of 4. If I try any one of the sticks the same thing happens. As soon as I put a second stick in the machine doesn't boot.
