Well done before. The host will turn on the machine, the fan will turn, the host red light will flash, the green light has been flashing, the monitor has no signal, and the monitor will be ok. Consult an expert, but where is the problem?.
First reason: the memory should be loose, dial out, wipe the gold finger, blow clean slot, and then plug back into the OKTwo reasons: plug the display data line loose, to see if the plug is plugged into the display, or plug the computer there loose, check to see the plug on the OK!Hope to adopt
Turn off the host completely and try againIf not, turn off the memory, pull out the eraser with your eraser, and install it back and try itOr not, put the BIOS's battery down and install it back in a minute
Solution 1:You press and hold the boot button for a while, then the host light is on, you may start the power supplySolution 2:Bad contact, alarm, or no display, memory and graphics cards are looseThen pull it out with your hand, clean it, plug it in, open the case, and don't put it back. (note the memory direction, find a screwdriver, pull the graphics card, clean it up, and burn the memory and the motherboard)Solution 3:May be heat aging, CPU temperature is too high, will automatically shut down. Which causes poor heat dissipation, you can change the heat sink fan. The heat of the power should be no problem ~ look at the landlord said the situation may be CPU cooling fan problem.. The main place where noise is generated is nothing more than a cooling fan; it can be too dusty to make a lot of noise
