onboard HDMI not working after case change

[Noobiq17]

hello,

first of all, pc spec.:

CPU: AMD A6-5400K Black Edition
MB: ASROCK FM2A88X-ITX+
RAM: Crucial 4GB DDR3 1600MHz CL8 Ballistix Tactical (1x)
PSU: Seasonic G Series 450W
OS: openELEC

as OS suggest, its main use is as HTPC. I have been using it for almost 3 years without any (hardware) issue. I didnt turned it on in the last 2 months. Few days ago i moved this HTPC to new case, and when i turned it on i got no video signal.

-I am using onboard hdmi output (as i always did), connected to projector, which shows only "hdmi 1 no signal"
-DVI works fine
-i made sure projector and hdmi cables (i tried 2) works fine.
-OS and everything else works fine, but didnt tested it much.
-also updated BIOS to newest version (3.40 i think, not sure what was previous version)
-when HDMI cable is plugged in on both sides, kodi (openELEC) detected it.

somewhere on this forum someone suggested new APU driver and it worked, but that was for windows.


i will be glad for any suggestion.

Thanks.

Reseat the memory.

Install a Case Speaker.

done. nothing changed.

right, i forget to mention speaker. sometimes its silent, sometimes just one short beep, and sometimes 5 long beeps. it was always this way since i purchased it, but it worked fine so it never bothered me.

Thanks.
