none of my USB or inputs detect keyboard and mouse. when started, all fans turn on including heatsink fan. Motherboard green LED light is on. No beeping noise are made. so after its been powered up the monitor is in sleep mode from the initial power start. computer ran fine last time it was used. computer has been stored away for awhile. Is it possible that my motherboard or CPU is messed up or fried? I tried using the same monitor on an hp tower and no mouse/keyboard is even needed for the monitor to come to life. not too sure what else it could be....like i said everything seems to turn on just screen comes on in sleepmode cuz no usb and keyboard/mouse inputs do not work.
