Optiplex 7010 SFF no POST when network adapter in PCI-E x4 slot
Just as the title suggests, my machine refuses to POST when I install a tp link TL-WDN4800 wireless apapter on the "wire x4" PCI-E slot (the bottom one according to the manual). If I install the adapter in the top slot, everything works fine.
Can anybody help?
more details: The machine doesn't make any beep sounds when trying to boot, and no video comes up. Can only restart by holding power button down for some seconds....
