dell OptiPlex 780 sff freezes on dell splash screen.
tried removing and reseating everything. checked each ram on another pc and they are working fine. reseated processor. removed every peripheral. still no luck. reconnected psu cables too.
1 4 diagnostic lights turned on. no beep
anyway been able to get pc go past splash screen once after clearing cmos and removing hard drive and optical drive but pc freezed on bios setup.
please help! is my mobo is the culprit?
