When I went there, I didn't go home for a while. It took me some time. What happened second days later?
1 first, make sure the power is ok! I suggest you try a power supply first! The low power supply has this performance; [when it comes to repairing, there are no problems at home, with some time, second days again.] good or bad at times!2 [computer only host start] are you sure it's really started? When you start, do you hear "drip"? You have to hear it,3, if not heard, check CPU, memory, graphics cards and power to plug the plug in the motherboard!4 if you hear, check the monitor, signal line, video card
1 lack of power supply2 socket with household appliances caused by power loss don't share3 external device problems, such as video head, mouse or keyboard connection4 internal contact of machine is bad5, the machine temperature is too high, cool, the machine can be lit, the temperature has gone out6 the power line has a problem, change the power line7, when the host boot, there is no music on the phone, and some may be a problem with the display card8 think about it first
Your host can only show that the host is powered on and has not worked properly. First, pull out the memory bar and find the eraser. Try the gold finger. If not yet, reset the COMS, remove the battery, discharge, and try again
