hi guys
this board came with short circuit in VTT_CPU_VO at first
short circuit solved by replacing Q8201,Q8202,Q8206,U8101 and U8201
now it turns on normally,use 0.6A and no display
all voltages are good exept +Vcore
+VCORE=0.8V
it looks that system dosn't run CPU
what should i do?

R EZ A Flash BIOS?

i tried, no change

i turnes on itself
by holding power key it not turn off, just restart quickly
