![]() I have now spent far more time on this than I anticipated - though am glad to have learned so much about computers in the process - and frankly do not know how to proceed. So I brought it back and again, the mobo appears to be faulty. The PSU and all other components are not faulty,as confirmed by the PC repair-shop previously. Then, to round off my exams, I breadboarded everything again - CPU,CPU fan/heat sink,8GB of ram in DIMMA2 and. I then replaced the motherboard, 6 months later, with another MSI B250M - assuming I was unlucky due to some manufacturing problem. I therefore reached out to Amazon again to replace my mobo under the 1 year warranty. They concluded that the motherboard was faulty, since all my other components worked normally in their test rigs. As they have their own test rigs and have extensive experience in diagnosing PC builds, I have no reason to distrust their assessment. So - after checking over the PSU with a multimeter (all voltages were correct according to the Mobo manual) and breadboarding my setup under different conditions (changed sockets, cable, RAM, fan, etc.) the system still refused to turn on beyond about 5ms of my CPU fan turning when I toggled the PSU.Ĭonsequently, I brought my motherboard, CPU and a stick of RAM (8GB crucial) to a local PC repair shop. Based on this, I contacted my supplier - Amazon - and had it replaced. Originally, this appeared to be because of the CPU - since the motherboard flashed the diagnostic LED corresponding to "CPU can't detect or fail". Unfortunately, when I assembled everything -slowly- according to the manual and with reference to YouTube videos the system would not turn on. The B250m had solid reviews from customers, supported my CPU choice and came with a good array of features such as an intuitive BIOS and support for numerous system fans. This was to be my first build, so I made sure to read up on every component carefully before making any purchases. As noted above, about 6 months ago I that for reasons unknown to me, my MSI B250m (mortar) motherboard failed to detect my Intel I7 7700K processor. Upon recommendation, I am now posting this under the original topic. Another thread but for the bazooka motherboard ( here) mentioned clearing the CMOS, however there are only 2 pins at JBAT1 on the mortar (instead of the implied 3) and no jumper, so how - and is it necessary - to clear it? Could it be a manufacturing problem with the CPU? If so how can I be sure?ģ. Do I need to update the BIOS for the motherboard to be able to detect the 7700K CPU? ( this seems to be the case for the Bazooka version)Ģ. Checked the board was not short-circuiting and was properly mounted in the caseġ. I grounded myself while assembling the computer to prevent static damageį. Using a magnifying glass, I found no bent pins on the CPUĮ. Confirmed the RAM is slotted into DIMMA2ĭ. ![]() The CPU is oriented correctly (arrow is aligned, as are the notches)Ĭ. However, when I connect power to the system and turn it on, the CPU fan spins briefly and a RED diagnostic LED turns on According to the manual, this means the motherboard can't detect the CPU or that the CPU failed.Ī. I have recently assembled my first Desktop build using MSI's B250M mortar motherboard.
