@David09 - I’ve read the same thing, but I have never done any BIOS updates. For that matter, I rarely even get into the BIOS unless I am in safe mode or something like that.
Something weird would have to happen for me to start messing with my BIOS settings. The article talks about passwords but I don’t even set passwords for the BIOS either.
From what you’re describing, I would check with your monitor’s software driver first. Download the latest driver for your monitor from the company’s website. See if that fixes the problem.
If it doesn’t, I would start looking at RAM. You can find programs on the Internet that will run checks of your RAM to make sure that everything is functioning properly.
Lastly, I would run a virus scanner and see if that resolves it. If all else fails, go ahead and reset the BIOS like the article says, but again, that’s the last resort.
