    Can't even see BIOS screen after changing setup

    lucas.leal

      Hi,

       

      First, my desktop configuration:

       

      Intel DB85FL

      Core i5 4550

      HD 500 GB

      8 GB RAM

      GTX 650 1GB

       

      Recently I reinstalled my SO and did it sucessfully so I went back to the BIOS to change the boot order (I remember I unmarked Legacy Boot and UEFI boot). After I've done that, my computer wont boot anymore. I mean: not even the BIOS screen (that intel symbol with the options to hit on the keyboard - F2 for enter setup, F7 to update, etc) appears. No video is displayed (the monitor keeps asking to plug the HDMI cable) and i can hear long beeps and long intervals for a while and suddenly they stop, but the computer still works (all fans and leds are on since the begining, but no video is displayed).

       

      I already tried:

       

      - Checking RAM.

      - Running with onboard video.

      - Recoverying BIOS with a .BIO file in a pendrive (done sucessfully but the problem is still occurring)

      - Unplugning the jumper (wich lets me see the BIOS screen but displays that 4 option menu in which any option I choose it will ask to reconnect the jumper and problem comes back when plug it and power the pc again).

       

      Can anybody help me? I can't belive I just broke my mother board configuring the boot order D:

          Hi lucas.leal, perhaps you will be able to access the BIOS by moving the jumper to pins 2-3.

          It may also help removing power and CMOS battery for 20-30 minutes.

          Otherwise, can you provide more information about the amount of beeps?

            Hey Joe,

             

            I already tried moving jumper to pins 2 - 3 and the same problem appears. The only way I can see any video on the screen (and it is the BIOS screen on wich I can't press F2 or F7 or F10) is when I remove the jumper. Then after that 4 option menu, any option I take leads to the same problem: no video again.

             

            I just noticed that it may have nothing to do with the BIOS anymore: according to the beep code of my motherboard, this is a problem with the video.

            I can hear 2 long beeps with an interval of 1 sec and then a pause of 2.5 secs. This is repeated once and then my computer boots normally with no video. It happens exactly like described here (Desktop Boards — BIOS beep codes).

             

            I already tried powering up my computer with the off board card removed but the same problem appears. Is it possible that my PROCESSOR is damaged?

              It is possible but I consider it is a rare behavior to get video for a brief moment and then two beeps, even with the graphics card connected.

              At this time only swapping parts will indicate the part affected.
