I've had my pc for about one year in the past 3 weeks whenever i turn on my pc the leds would turn and the fans will start spinning however my monitor is just blank. The monitor sometimes works but I don't know why. so basically whenever i turn on my pc my monitory wont respond.
My friend came over to help me refit my graphics card but it didn't work,I have also made sure the monitor works by connecting it with another device, so ill try to dust my pc now. Thanks for the responses guys
I'm not that good with technology so I was wondering,during the air dusting do I have to get deeper into the PC by taking out some components or do I just clean the dust that I see? just for reference I use the cooler master - enforcer case.link to the case click here
Just blow out what you can see at a year old it won't be too bad unless you have pets fluff can gather between the heatsink and fan on the cpu so this is the only part that may require removing during a dust out.
However in the is case I don't think dust / overheat is your problem. when you used the monitor on a different device did you use the same cable?
If monitor OK then cable - graphics card or motherboard are suspect.
Can you connect to onboard graphics? remove the card and connect to onboard graphics to prove graphics card faulty.
