Power frequency howling should not tight?
If you have a maintenance department, you can try changing parts. How long it will take is really hard to say. You try to dust first. By the way, do you see if there is any leakage of capacitance?.
Is not just when the boot, with a step on the cat's tail like the squeak of the call, and then about 10 minutes after the boot up and down, on their own okay? My computer is also, you put the power down, and then go to the soil, do not need to open the shell, on the outside of the good, and then re installed, and on the OK. Not too big a problem. There is no need to change the fan.
My computer power has been going on for almost a year. Pangu S600 now has some high frequency whistles. Is that a bit of tinnitus Zizi Zi sound. Whether this expression is tight or not will damage the computer hardware. I'm rather partial to buy a fan. It takes 8-9 hours by coach.I was playing the game when my voice was out of sight.
