Recently I was trying to install a new graphics card and in an attempt to do so, I accidentally put my Serial Port settings, in bios menu, to "disabled" since then, my pc is not booting into either windows or boot menu. What I think now is that my serial port is disabled and is no longer able to connect to onboard graphics card(Integrated Graphics Card) Now what I believe is that the solution to this problem must be to somehow reset the BIOS settings (I tried to do that manually by moving aroud the jumpers but still does not work) Can someone help me with that? Thank you!
