I build my own rig using ASROCK Z77E-ITX LGS1155 motherboard back in 2nd Apr 2014. Was a basic unit without GPU.

It works fine in the past and usage is low.

Last week, when i on the PC, it does not project anything on monitor. Besides i can see the fan on and off intermittently. I also notice the CMOS light at the back was blinking.

I have replaced the CMOS battery, RAM checked and its working fine, reset the CMOS (both pressing the CMOS button at back as well as short the CMOS jumper. Still problem exist.

What is wrong with the PC? Is the board still under warranty?

Not sure about the distributor cause there is no sticker on the packaging and the shop i bought from has closed.

In that case can't we go direct to the service center direct?

Of course assuming the board is still within warranty period, hence asking question about the warranty period for this board.
