Now I'm having an odd error with my POST. Whenever I turn my computer on it will pop to the bios and hang. It wont continue to boot unless I press a key on the keyboard, No key specifically however. I had a random day where this no longer occurred and it booted fine, but nothing since then. Also ever since this has occurred I've had no onboard sound/input for microphone (when its plugged in it says otherwise). I've been having to use HDMI sound through my videocard.
Things I've tried : Reinstalled OS, Reset CMOS, Reset UEFI/BIOS, Removed BIOS battery for 15 mins let it sit. Reseated all devices Ram/Video/PCIE/CPU.

First of all, welcome to BC !



Reseated all devices Ram/Video/PCIE/CPU.


This has got virtually nothing to do directly with your present problem - but when you reseated the CPU did you clean the top surface and the bottom of the heatsink and replace the thermal paste ?  If you didn't, then you should do so as a matter of some urgency.


With regard to your booting problem, is your SSD listed in the boot priority menu as the first device, or equally well, as second device after a CD/DVD drive ?


When you took the CMOS battery out, I would have been inclined to replace it. If it is the common 2032 type, they are not expensive, and while they are commonly good for up to five years or thereabouts (note to self - yours is due replacement !) you can never know how long it was in store before it was fitted to your motherboard. And it is well known that  batteries like this when nearly discharged can cause some weird faults.


With regard to your microphone problem, if you have a look at your audio in Device Manager, are there any exclamation marks or other warning symbols against it ?  Once you have sorted out your boot problem, uninstalling and re-installing your sound drivers might be worth doing.

Also to note, when you took out your battery, did you also remember to disconnect the power supply from the wall to remove any power from the system?
