So this morning, after cleaning out my PC (especially the cooler) of dust and reassembling it, when I powered it on, there was no signal going to my Acer XF240H monitor. All morning, I was trying to fix the error repeatedly using the method where you unplug, wait, then replug the monitor, replacing the CMOS lithium ion battery (only once), and unplugging and replugging both the monitor and the PC (and I had to force shut down my PC many times) all of which were to no avail.. I even tried using an HDMI cable but also to no avail. Can you give me the best step-by-step guide to repairing this issue? Thanks.
