This morning, I was using my computer normally, nothing seemed unusual, other than my Ethernet cable not being recognized by my motherboard. I waited a while and rebooted and the light for the Ethernet cable being detected came back and the computer started working as normal. After about an hour, I needed to print something and decided to plug in my printer USB cable. As soon as I plugged it in, the USB port started smoking, and before I could turn off my computer, it shut off itself.
At this point, I made sure that the smoke and smell emitted from the computer was indeed from the USB port and NOT from the PSU. I assumed that this fried USB port could be due to the port being unused and undusted for months. I waited about an hour and then turned on my computer. All LED lights, fans, accessories (keyboard and mouse), turned on as normal. I was able to change settings on my keyboard and changed light options. All fans within my computer, 4 external fans, CPU fan, GPU fan, were all working as intended. However, there is no display. I'm not quite sure why.
I have two monitors, one is connected via DVI port and one is connected via HDMI port, both to my GPU. However, neither seem to be recognized properly. After turning on my computer, there is no smoke or smell being emitted. My next step plan is to open up my computer and dust it out, and see if the visible capacitors on the motherboard are fried.
I have turned off the computer, unplugged all plugs and turned off power (PSU). Unfortunately I dont have any spare PSUs, motherboards, or GPUs to troubleshoot with.
Any help would be greatly appreciated. Thanks!
