Hiya BBB
You sound like our kind of nutter
I regularly get that error message in my error log and don't have any problems with freezing. However the aforementioned Serenity does have the messages and her PC regularly freezes. I have suggested that she buys the PC a sweater and some warm socks
Updating your BIOS can be very easy and it can be fraught with danger. It all depends on the make of motherboard you are using and your personal level of technical expertise.
I'll let Serenity tell you how her BIOS upgrade went
I'm not ready for a nervous breakdown today
Could you let us know the make and model of your motherboard? This information will allow us to find out if you need to update the BIOS. My guess is that you probably don't and that whatever is causing the freezing lies elsewhere
