Long time since I've posted in here, hoping someone might have seen this problem before!
I recently built myself a new PC for the first time in what feels like 10 years. In actual fact it's about 6, but either way, I'm a bit out of practice when it comes to hardware troubleshooting!
About 50% of the time I turn the PC on the ASUS logo will show up (with the "press delete to enter setup message") and stay there for a very long time. Sometimes it continues after about a minute, sometimes not. The other 50% it will post after a few seconds.
When it happens I have to turn off the PSU and wait the board to discharge (about 10 seconds) to get it to boot again.
It happens with and without the graphics card and DVDRW installed. I haven't done any more testing with other components disconnected, but there's really not much to disconnect.
The bios is that new-fangled UEFI thingy. I've messed around with the various boot options (USB detection, fast boot, boot order, etc), and legacy compatibility modes, but nothing has worked. I don't think it's getting to the point of trying to load the OS, because when I disable the full screen logo I get a blank screen instead of the old-school text screen which shows you CPU speed, ram etc.
System is perfectly stable when the OS loads, in Windows and Linux, and I've stress-tested it with Hyper-pi, 3dmark and general gaming. I've also updated the bios to the latest release. So the way I see it there's a bios config issue somewhere, I just don't know where to look!
