Dears,
I just buy PNY RTX 2070 8 GB and try to install it on My old x58 Motherboard Asus Rampage2 extreme ( 6GB corsair ram) . but my MB issues one long and 3 shorts beeps means no graphic cards deducted .
I update the Bios to last formal one from ASUS and problems still as it is .
Are there any solutions for that problems ?
