[SOLVED] Booting problem of slightly older pc, BOOT_DEVICE_LED solid red

May 5, 2020
Hey guys!
I build my pc some years ago and i have resently been necleting using it, but then i tried turning it on, and it beeped the nice sound i love and like when it booted. But then a black screen apeared and said No drive were found and booted to bios, where i could navigate in about 5 seconds an then it froze.
I opened the case to see if there was any wiring og any obvious faults with the hardware and the boot device led is solid red. What does this mean? I am a bit of a greenie at this, please help.

Specs are:
Motherboard - Asus M5A99X EVO
PSU - Cooler Master 500 W
CPU - AMD FX 4100 - FD4100WMW4KGU
RAM - Kingston KHX1600C9D3B1K2/8GX
