I install an additional Gigabit ethernet card (TPLink TG-3468) on the PCI-Express slot and now the PC stuck at start up (Intel Logo with some blue background) and can not go any further. If I remove the card, it boots up fine.
BIOS version JOQ3510J (ver 1109), Intel Q9550 Quad Core CPU, 2 x 4GB Corsair DDR-2 800 RAM (5-5-5-18). Any help appreciated.
Sorry, forgot to mention the card works fine with a MSI IM-Q35 motherboard (Q35 chipset) but not with an Intel DQ35 motherboard. The only keys function when stuck on the Intel screen are Ctl+Alt+Del. Other keys pressed only retun a beep sound. I also have another server with identical hardware and it also can not go pass the logo screen.
I've got the exact same problem with a DQ35JO. It's a Core2 Duo 3GHz with 8GB Kingston DDR2 800 RAM and RAID 5. BIOS version is 'JOQ3510J.86A.1109.2009.0716.0319'.
Same story: if I put the card in, it freezes on the BIOS splash screen. If I remove the card, the system boots and works fine. I tried swapping which slot it was in too, but it doesn't work in either.
