Just built new system with the MSI Z87 -G45 motherboard. Have had nothing but problems with this board since i built a new system wish i would have stayed with asrock boards. First thing is the killer e2200 problem alot have been having. Wont Show a network card in device manager at all it did when i first put the system together before updating drivers and now nothing cant connect to internet and does not show in devices. @nd problem my dvd drive will not work unless i restart computer with disc i want in. if i try and change discs while on the drive disspears all together from device list and drive list on my computer. Any help with these issues would be awesome.
