My mobo doenst show the logo of msi at the start up, it only shows a black screen till the system boots, if i press del at the startup i get stuck on the black screen forever, i alredy removed the battery from the mobo and replaced, but it can't get into the bios
Im having this problem too with an MSI B350m Mortar motherboard, there are 2 ways around it for me, shutdown the computer, power off the psu and remove the power cord, plug it all back in after a couple of mins, and then I can get into the bios.
Or the 2nd way is to clear the bios using the jumpers on the motherboard, you dont need a jumper cap, anything clean and metal will do it, short the pins for about 10 seconds and then power on and try and get into the bios.
I guess MSI botched something in there last bios update, I have reported it to them, hopefully they'll fix it in the next update which should be this week sometime, if you want to risk it, you can download the beta bios here:
