All in One Computer in Sleep Mode, Won't Wake Up

[ron1254]

My computer/monitor will go to sleep after a period of inactivity but won't come out of the sleep process.... i think it has something to do with the monitor because the computer is set to never sleep on the CPU.... my system is an all in one Gateway ZX4300 AMD Anthlon IIX4 650e...64 bit OS....ATI Mobility Radeon HD 4200 display adapter .....running Windows 7

Reset CMOS to factory see what happens, THEN I suspect Windows.

My monitor would not wake up. Usually no mouse or keyboard either. I ram memtest and ram was fine. I went into bios and ram was defaulting to 1600 when it was on auto. My ram was 1866. I set the ram to 1866 and have not had the problem since. (months)

This sounds minor but, it is a PITA to always restart.
Maybe someone can help out with an answer on changing ram speed settings because I'm a noob.
Mine was pretty easy.
Also mention if you have changed your ram from the factory installed ram. Mine was on a new build if I would have installed 1600 mhz ram I don't think I would have had any problems.

If you can not change the settings on ram speed and you are defaulting to 1600 or whatever and your ram is something else I would consider changing the ram to match the default. Ram is pretty cheap.
Best of luck.
