Common Fault Diagnosis

1. Turn on computer, no display
☛ Please try to wipe the connection figure with eraser, don’t use Corrosives, such as ethyl alcohol.

2. Windows often boot into safe mode automatically
☛ Please try to slow the speed of data read in CMOS setting.

3. Computer crash randomly
☛ Please try to slow the speed of data read in CMOS setting. If don’t work, use same frequency RAMS.
