ASRock Z370 Pro4 died after BIOS flash

   Hello,

Yesterday I tried to update my ASRock Z370 Pro4 BIOS, firstly, using Windows installer but despite the "inallation succesful" information it remained on my 1.80 version. Then I uploaded USB flash version in the root directory of my pendrive and tried to update it via Instant Flash, the PC restarted and I lost my video and the fans started to act like crazy (spins normally for few seconds, then spins on max revolutions for few seconds, then normal again and it repeats).

I unplupped all cables including the power one, pressed the power button for 20 seconds, unplugged all sata disks, took out the battery and shorted CMOS "clear pins" using screwdriwer, first for few minutes, but without effect, then repeated for about 8 hours. Tried connecting different monitor using both HDMI and DP and also tried to connect to integrated graphics using board's HDMI port but there is no difference,

Is there anything I can try to do to fix it? Im afraid my warranty expired so I wouldn't be able to send to AsRock anymore. The local computer service would have the tools to repair it or they would just try my approach?

Regards
