i have been using this monitor for a bit and it has worked fine but following on from these exact steps i have taken.the monitor just says it is going into standby mode....i opened up my computer to have a look at my ram type.so i took the ram out.had a look and placed it back in...turned on computer and it was fine but monitor wouldnt come on.so i tried taking out video card and putting back.took out ram and put back .tried different monitor which has the same problem. tried my monitor in a different pc and it works so the problem is within my pc and not the monitor.reeally confuzed as to whats wrong and being no computer expert.thats as far as my knowledge goes so need a lil help lol.thnx
