Hi guys, i'm new to this forum so sorry if i use wrong or bad words.
I got a system that runs fine in almost a year but suddenly my PC didn't show anything on screen eventough the pc boot up fine.
The proof of boot up fine is i can hear the windows 7 welcome sound and login sound when i entered my password and press Enter.

This has happened several times but not all the times. Usually from cold start.
I tried changing VGA from my usual one to GT 630 and it run fine. I tried integrated too and it run fine.


Now it's working as usual, but it's annoying if this kind of thing keep happening.

My spec :
Core i3 3220
Corsair Vengeance Black 12 GB (2x2 + 1x4)
Seagate 500 GB + Toshiba 1TB
Digital Alliance GTX 650 Ti OC 1024 MB DDR5
Asrock H77 Pro4/MVP
Super Flower 650W 80+ Bronze Modular

please give me solutions because if this keep happening, i want to RMA the one that make the problems.

really ? what make you can say that ?
i wrote that the monitor shows fine with different vga (gt 630) and integrated one

but if it's true, how can i check it for real ? so i know for sure that my monitor is the one making the problem
