Hi there (sorry if this isn't the right place to post something like this) My monitor stopped responding to my computer a few days ago, now I know it is not any of my components that are the problem or that it is the monitor that is the problem as I have tested them all on different systems. I've tried booting with just the CPU, heatsink, graphics card and PSU and 1 stick of RAM in a slot (I have tried each of my memory sticks in all of my RAM slots) but to no avail, I have also tried to reset the CMOS but that did not work either, and also tried to disperse the internal voltage a few times and still nothing. I'm really stumped as to what the problem could be and would love it if someone helped me. I do not have a case speaker or a speaker on the motherboard so I am unable to identify beeps. system specs: ASUS m2n-e sli mobo AMD athlon x2 3800 2GB DDR2-667 memory nvidia 8600GT 500W PSU 160GB hard drive. Once again any help would be greatly appreciated.
