We have two ICT suites of Lenovo M58p's and now I've got two that will not boot. They completely lock up at the 'ThinkCentre' splash screen, it displays the message 'System is starting'. Goes no further than there. I've tried re-seating the RAM, swapped the RAM, removed all RAM, tried a different HDD, reset the BIOS and even changed the PSU...
I honestly am out of idea's... Anyone come across this or anything similar??
