Hi,
Hope you'll understand my English, cos I'm French ;) I'm more famous on the French Kioskea, CCM
if you have the message "check signal cable", it means your screen is not connected, or your graphic card doesn't work at all
the pc is only 7 months old did it work ok during that time ?
then you returned it and they changed the mobo : I think it's not only the PCI-E slot which is faulty, but the chipset too : I read a lot of problems about nVidia chipsets on Intel CPU mobos...
My piece of advice : buy a mobo w/ Intel chipset (P45)
