After getting a new PSU to fix another problem, I ended up using the cables from the old PSU for the fans, hard drives, and optical drives, because I heard that is a thing I can do. Well I guess it's not a thing you can do because on bootup, my fans didn't turn on and a bad smell started coming from somewhere in the system, though I believe it to be the motherboard. I immediately turned off and unplugged the system, though by then the damage was done. After swapping out all of the old power cables for the new ones, I rebooted. The BIOS not only failed to detect a boot-able drive, but froze upon me trying to enter the BIOS set up by pressing F2 or Delete. Help?


My system is as follows

Windows 10
Asus P8 Z77-V LK
Intel i5 3579K (Not overclocked)
EVGA SuperNOVA 650 G1
PNY 2G 960GTX
Western Digital 1TB Hard Drive
PNY 240GB SSD
PNY 16GB DDR3 RAM
2X Optical Drives (Different brands, one is Asus, don't know about the other, but the other was salvaged from an older system, it's been in there for the whole life of the system)
Sabrent internal card reader

Always use the cables that come with the power supply! Sometimes they wont even fit between brands, but unfortunately yours did.
If the bios is freezing then you have major issues, I would replace the motherboard and HOPE that it stopped there and everything else is salvageable.

If you happen to have a spare board you could at least test your parts by connecting them one by one and making sure they are recognized by the bios.

By any chance did you try booting with the old PSU? If it boots with the old one then you may have just ruined the new PSU so you could consider yourself lucky and just have to replace they new PSU and nothing more.
