Let's google with https://www.google.com/search?q=PCMatic+bsod and yes, you find folk talking about this.
Here's the moderators take on this. Optimizers, driver finders tend to create issues rather than solve them.
Not a product any moderator I know uses or advises.
-> My take on driver finders is simple. Drivers don't wear out. Updating a working driver automatically is a great way to automatically create issues.
I recently installed PCMatic on a couple of computers. I don't know if it's related but all of a sudden I'm having problems with a blue screen that went into 'auto repair, diagnosing, computer won't restart'. In order to get the computer operational, I had to do a Windows 10 System Restore. Again, I don't know if this is related to PCMatic but is anyone experiencing similar problem?
