help PC wont boot past post, cd/dvd drive not registering in bios etc.

hey guys.
my pc was working fine last night, switched off before bed as usual, woke up this morning, switched on and the machine would not boot up to windows from post. i accessed bios but my cd/dvd drive does not show up there, my hdd does but it will still not boot from startup :/ this message is displayed on the right hand side of boot section of bios 'A device enclosed in the parenthesis has been disabled in the corresponding type menu'. my hdd is listed in brackets, which from what i have discovered so far is not meant to be the case, lol..im not very pc literate so i'm beginning to pull my hair out over this..i can get into windows but i have to go into bios, then exit it and it boots up that way, altho it seems to boot up a lot slower. i cant for the life of me get my cd/dvd drive to show up or even work,it does however have power etc, it just doesn't register on the pc so no hope of me doing a full reinstall at mo either :/ any help with this would be much appreciated as im slowly going insane, lol :) last thing the pc did before shut down last night was a windows defender update, i tried restore but hasn't changed a thing

Hi,

Kindly follow the below mentioned steps which could fix the issue:


Check the performance in safe mode/ Safe mode with networking.

I would suggest you to do Flee Power.
In case you have Desktop, remove any 3rd party peripherals and power cord from your Desktop, press and hold the power button for 20 seconds to discharge any residual current inside the desktop.
In case you have laptop, remove the battery and charger/ac adapter/power cord from your notebook, press and hold the power button for 20 seconds to discharge any residual current inside the laptop.

If the issue still persists, run a test on the Hard Drive to confirm functionality. If you get any error code, make a note of the error code.

Kindly revert and let us know the status.
