Hey so I'm new to pc building and I did research on what to buy and all. I bought everything and plugged it in into my motherboard. When I was done plugging everything in I pressed on the POWER SW.
All fans started blowing and my gpu started lighting up. So I thought I did everything correctly. When I went to the assigned HDMI-channel it showed me I had no signal. So I looked up on youtube on how to fix this problem. They told me to remove ram clean it and tried all the 4 slots on my motherboard. No luck. Another fix was to unplug the gpu and look if your gpu is broken or not and I plugged the HDMI into the MoBo. Still no luck. Another fix was to remove the circle shaped battery for 5-10 mins. and then put it back in. I did but still no luck. I even unplugged everything except psu and the power cords that were needed to turn on the PC and started plugging my parts one by one into the MoBo but even that didn't help resolve my problem. So this is a cry of help to anyone who knows how to fix this.
