ThinkCentre M92 - Black Screen Blinking Cursor

Hi, I recently purchased a Lenovo ThinkCentre M92 from a friend and its been working perfectly until recently where was having some issues with booting. I had a look on here if there was any BIOS updates to which there was, so i used Lenovo System Update to do this.

 

Now i am facing an issue where it will no longer boot at all, i get a black screen with a blinking cursor in the top left corner, i've entered the BIOS and done F9 load optimized defaults and then saved and exit makes no difference. i've tried making a bootable USB and CD to flash the bios again but it just keeps loading the same screen no matter what i try.

 

Could someone please help me as im out of ideas and hope its not broken all together Smiley Sad

Re: ThinkCentre M92 - Black Screen Blinking Cursor

I've just re done what was advised in the manual and still no joy when try boot with the jumper in position 2 and 3 i just get 2 short beeps, when i return to 1 and 2 it boots but then get 2 errors error 0162 - system data integrity check failure & error 0175 - system security - security data corrupted.

 

If i enter setup and then just save and exit it goes back to the blinking screen
