no boot, blinking cursor and no usb

[Gerome_3]

I recently rebuilt my pc by replacing parts with new ones of the exact same type, i was playing a game and talking to a few friends over discord and suddenly I notice the screen stutter for 1 second till it totally froze but for 3 seconds i could still hear audio till that also turned off. Upon restart it started "Scanning drives....." I know the stupidest thing I could've done was to restart manually which I did and the same scanning drives came up, after searching for a fix assuming from reading other suggestions this would last for hours i decided to reset the cmos. Turned computer off and straight away without draining power I jumped the mother board with a screw driver and the next time it loaded it was the blinking cursor.

When I unplug my hdd it black screens for a while then goes into the UEFI Shell which is normal but i cannot exit it because I also have no power to usb since the freeze initially, I'm wondering if this is a hdd issue because I only bought this new one 1 week before and everything was working fine, ive also just replaced the motherboard, psu and cpu. only thing i havent replaced is the gpu and the ram but that seemed to work fine.

Note: i have no way to access the bios since i have no usb power but im thinking maybe a ps2 would work?

any help would be appreciated and thankyou in advance and apologies if this is in the wrong section

SPECS:
CPU: AMD-FX 8320 black edition
GPU: GTX 960 MSI Geforce
Ram: hyperX 8gb
HDD: WD WD10EZEX 1tb SATA3 Hard Drive
PSU: Corsair CX850M 80+ Bronze
Motherboard MSI 970-g43

Seems like your file system on disk is corrupted or disk itself has a problem.

Did you try resetting CMOS/BIOS ?

woops im new to this ahah accidently deleted this, I have attempted to reset the CMOS in the very beginning ( at the time every time i would turn my computer on which was twice, it would be the "scanning drives..." text) since resetting cmos I have gotten the blinking cursor error

Blinking underscore means that OS is not booting properly any mostly cause by bad boot sector on disk. That could be SW or HW issue.
As for no USB working, I don't know why but if you could find a PS/2 KB you may get into BIOS that way.

So you're hinting at buying a new HDD? I have no issue with that and as for a PS/2 i think that is easy enough, I guess just my luck that I would be sent a bad disk that would malfunction a week after hmm. Appreciate the diagnosis! I'll keep the thread open and post updates when I receive the new hardware.

Doesn't necessarily mean that disk itself is bad, SW can make mess of boot sector too. But, you need to sort out problem with USB and KB first even if you get new HDD.

What could I do if it turns out to be a software issue and I think the USB will be solved with the solution to software?

 

[CountMike]

No SW will change behavior off things in BIOS because drivers are in the OS and that didn't start yet. Best way would be to make a bootable USB od DVD with same version of windows, boot with it and choose Repair option. If it's successful, it should not change programs installed and user data.

sadly i have already tried this and the usb key is enabled as my first boot option (pretty sure) and it has not picked up or even started to boot from the usb

 

[CountMike]

So you'll have to get into BIOS somehow first, if USB doesn't work maybe PS/2 will.

Roger that! will do.
