Hi,
I was going to use my PC this morning but changed my mind whilst it was booting and depressed the ATX power button for 4 seconds to switch off - unfortunately it now won't start at all. Turning on the power all fans start but there are no POST beeps or signal to the monitor. The DRAM LED on the P7P55D PRO MOBO remains illuminated so I have tried pressing the MemOK! button which causes the LED to go through a sequence of flashing and forcing a number of reboots but with no end success.
Any ideas of what other basic options I could investigate before contacting Support ?
