Dear Forum,
My Monitor is AOC LED monitor, it works fine till date but from few days my monitor shows "No Signal" after 15-20min of working. RAM/Hard Disk and Monitor working fine but after sometimes CPU is neither restart or shut down nor showing processor blinking light, it require to power off from source. Few days before I installed 2GM DDR2 RAM in addition to 1GB DDR2 RAM, I tried replacing each other and removing one by one. I also tried to clean CPU by blowing air to make dust free. Also I replaced new VGA cable by old one. Monitor works fine but he problem persist after so many efforts.
Is it due to CMOS battery or Motherboard problem..??
Please suggest the way forward to solve this problem.
Regards,
Ashok
