I'm trying to build a home PC to use as a PVR. I have all the hardware I
need but the PC won't boot up when I put the AverMedia PCI TV capture card
in. You know how the LED on the monitor goes green at the start of the boot
up, well it doesn't even get to that point - I just get power on and then
nothing - no BIOS screen, just blank. The capture card works fine in a
different PC with no boot problems.

The mobo is a GIGABYTE GA-8I848E-L, the TV capture card is an AverMedia "TV
Capture 98", and I also have a NVIDIA GeForce4 MX 440 AGP video card in
there. I've also noticed that if I put a PCI video card in one of the slots
that causes the same problem, but if I put a PCI NIC in, the boot up is
fine.

Can anyone please help me as to why it's preventing the PC from booting up?

Thanks in advance,
Phill Edwards
