Within the past few days my Acer here has been faltering. First it started with my monitor. While rebooting it posts, the BIOS screen appears then the monitor shuts off. It boots up fully, but I needed to turn the monitor off and back on. With each added day I need to turn it off and back on more and more. I'm up to 15 to 20 times before it stays on. It starts out dim then gets brighter with each time. It flickers a little too before remaining on.
I thought ok, the monitor or graphics chip is going out, for after all it is 8 years old. But then today I goes to try and make a bootable ISO thumb drive with Rufus to load 10 with and that failed with a warning that the formatting process failed. Fat32 is the default for the drive and Rufus is performing NTFS. I thinks ok, I bought the wrong kind of thumb drive?
I scrapped that and went to my optical drive to burn to a DVD. That returns an error code 0xc0aa0301, of which is a faulty hardware problem.
So I started thinking that what are the odds of all this going wrong all at once? PSU comes to mind. Am I thinking right? If so, can it be tested with a volt meter? I would think it puts out different voltage for different peripherals?
The optical drive reads and plays music & video media and reads files on all ready formatted/made DVDs, but it just blinks when I put a blank DVD in. Strange.
