I'll save you all the sob story about the hours and hours and HOURS I've spent trying to cobble together a new-to-me PC and cut to the important part:
I've received a RMA number from ASUS after determining that my P5KPL-CM is indeed the reason my system won't boot. I had the mainboard packed up nice and neat and ready to take to the local shipping store when I read the RMA information e-mail and found:
P5 series motherboards must include the original CPU socket cover
Trouble is, I don't have the original CPU socket cover.
I know it's an old board and I know it's a longshot, but does anyone have a spare ASUS P5 series CPU socket cover? Apparently ASUS wants the exact same CPU cover as comes with P5 series mainboards. I'm definitely willing to reimburse the cost of shipping by Paypal.
I know I don't have many posts on these forums and most are from years ago, but a helpful hand would be very, very much appreciated.
