I don,t know how to fix this or what is the problem because this a first time this has happen since I own my computer. I only had it for 3 months. So can someone provide me with a solution what I need to do. thank you very much

I suspect a motherboard problem unrelated to the monitor. Only a PC repair shop is going to have the tools to diagnose the problem.

Good Luck
