A few months ago when I turned on my computer, it gave off a long 2-3 second beep and then 3 fast ones right after and then my computer wouldn't start. I was to lazy to look into it so I left it alone. Fast forward to the present. I've tried everything I know off and it is still giving me that 7f error code. I've taken everything out including the mobo, psu and even replacing the battery with a new one; (waited 20+ minutes before putting new battery in and powering it back up). Installed the mobo, ensuring it isn't shorting on anything else. Installed the PSU. Connected the power supply to the mobo with nothing else connected, hit the power button it seems to cycle/boot just fine. No error codes. Installed 1 stick of brand new ram into dimm 1 and same problem, one loud long beep and then 3 fast ones and the error code 7f. Repeated the steps using 3 other brand new rams and same issue. I was having the same issue with the old ram as well. Removed all the ram, installed the video card, powered her up and it seems to boot/cycle fine, but because there aren't any ram it won't post. Left the video card in, installed one stick of ram into dimm 1 and same issue. Mind you, the cd drive and all the hard drives including the sata cables are not connected. I am at a dead end here and about to take my 12 gauge to it! I've also hit the reset CMOS button on the motherboard and it didn't do me any good! Nothing is showing on my monitor. The monitor and cables are also good! Anyone have any other ideas?
