I left my computer on last night and just let it go to sleep from disuse, and when I woke up this morning it was on the “Press F2 or Delete to enter BIOS” part of the startup.

Inside the computer, the boot device LED is a solid red, but as far as I can tell the various lights involved for individual parts do light normally when power is turned on before the solid red light.

So far I have just tried to reset the CMOS battery, which ultimately results in the same state. The computer is about 5 years old and assembled by me from individual parts, with no hardware issues before today.

CPU - Core i5-4690k 3.6ghz
Mobo - ASUS Z-97a
GPU - Radeon R9 390
Ram - Crucial Ballistix Sport 2x8gb DDR3
Power - EVGA 750w

Also, sorry if my formatting is off or I haven’t included all information, trying to research this and get all my info for a 5 year old computer on a phone is an absolute nightmare, I don’t understand how people survive with a phone as their primary device for interacting with the internet. Ask for clarification or point me where to go and I’ll do my best.
