My computer will power on then it beeps twice and then four times. It will repeat this beep sequence until I power down. There is a RGB display on the screen and a message stating the monitor is working correctly. Any suggestions?
No power to CPU... open the case and gently wiggle the 4 pin power connector and see if that works. Or as an alternative you could check it with a multimeter. Set it to 20v DC and connect black to black - red to yellow... it should be around 12.45v +/-. The beeping is indicative of CPU.
