I have no info on my system other than what I can see on the case and motherboard. I hope to replace the motherboard with the exact same one so I don't need to buy windows and can use the OEM but need to know how to determine the exact correct board. I can got to ACER lookup and it seems they have all the info because it all populates but since I'm out of warranty how to I get this info? Thanks to any that help me out on this. I'm screwed without this PC. The startup beep code I get when it fails to boot is 3 short beeps a quick pause and 3 beeps then it doesn't do anything. I checked the HD and RAM in other PCs so I figure it must be the MOBO...
