So I picked the 790i up about a month ago for a new computer. Have been having a few issues but I've resolved all of them so far. Currently, the computer won't always start up. If I hit the power button, the fans spin up but that confirmation startup beep won't occur. I have to power the system down from the power button and try again to get it to start, at which point I get a message that the BIOS is in safe mode now and I need to reset my cpu/memory settings. It is happening fairly consistently now when I power down the computer. The only change is that I purchased a gtx 280 from PNY about a week ago, other then that no changes to the hardware have occured. I am running the latest BIOS P05.
