Question about Acer Aspire T690 (AST690UP820A) PC Desktop
Why is my pc buzzing when turned on?
Do you mean beep? Beeping may occur due to RAM corruption (indicated by three long beeps). Failure of input or output devices may also cause beeping. first unplug the RAM, if the same beep continues, then the culprit is RAM. if not,then replug it and unplug the KeyBoard. do the same with the rest of the I/O devices. Also try to put ur processor in ur frens PC, and vice versa, then u'll know if ur processor or the motherboard is not working.
