I have got intel DH87RL motherboard (latest bios 330) with 3 x PCI-E-x1 slots and 1 x PCI-E x16 slot. Recently, I purchased two Startech usb adapter cards PCI-E x1. These cards work perfectly with x16 slot but when connected to x1 slot the computer will not boot, and will reboot constatnly without any visual nor beep feedback. It's even impossible to enter the bios. Please help me.
I need to use as many cards as possible so one card in pci-e x16 slot is not enough for me.
