Spent over 2 hours and could not get the computer to boot up completely.  Kept going into automatic recovery and would end with a stop code: IRQL NOT LESS OR EQUAL; DPC WATCHDOG VIOLATION; PAGE FAULT IN NONPAGE AREA; SYSTEM THREAD EXCEPTION NOT HANDLED; KERNEL SECURITY CHECK FAILURE; MEMORY MANAGEMENT;  Tried to get to a point to start in safe mode but could not get there.  Did try for a system restore but the only restore point was a Microsoft system upgrade that was done when I started the computer on the 17th.  Want a refund and going to get another but not a Dell.
