PC Boots up but no display (GA-H57M-USB3)

[yashoshah]

Display (LG W2486L) connected through DVI-D port of motherboard (GA-H57M-USB3).
PC boots up ( I can hear the sound of successful boot in in Windows 8.1 as well as beep from motherboard speaker) successfully, the peripherals are ON (keyboard, Mouse) but there is no display on monitor.
When I reset the PC, the display appears on monitor and PC boots again-successfully.

Is my Display faulty or the motherboard malfunctioning??

BTW I am using 1st Generation Core i5, 650 having integrated Intel HD graphics. No separate Graphics card.

Soft Reset CMOS worked, but when enabled the XMP profile in BIOS, the problem recurred

P.S.: The same is the case when I am using HDMI, but is less frequent. Sometimes  display is there during initial start up with HDMI.

Only 3 things it could be.
Monitor, but it does work most times so prolly not it.
Motherboard, Have to switch it out to see
CPU.

your motherboard is over 4 years old so that could be it have you cleaned all the dust out of it?  Also clean dust out of CPU cooler.  Things wear out over time so if you get a new motherboard I would probably upgrade and get a new CPU also.
