i have been facing the problem for 3weeks already and the technician i hired has not solved the problem yet.
the problem was that:

when using the xfx r7850 double dissipation as the primary graphic, most of the time when booting the pc at first it has no signal and after a couple of tries(force shut down) it will operate normally but there is this time that it did not work and what i did was i reseated the gpu and when i turned on the pc it worked.
leaving the pc off for like 12hrs. again, the problem starts and i will just repeat the process and then goes back normally. but if i use on board VGA it works smoothly. the main problem is when using my GPU r7850.
i've played games for several hours. the problem is that after like 12hrs of not using it, the problem starts again.

so far i have tried re seating the RAM, tweaking bios changing the auto detection of graphics to PCIE.(but when i visit bios again it will go back to auto)
changing monitor.
trying different cables.
unplugging the power cord and holding power button for 30-1min.


p:s my father put a lot of effort on buying my first ever gaming rig that is why i cannot afford to let him worry if something happens to the pc. he's working at dubai with small pay/month. please help me.
