Clarification Request
So F1 is not working?

You should try the BIOS/CMOS reset. But the CM1740 appears to be a desktop, not a motherboard.

http://www.newegg.com/Product/Product.aspx?Item=N82E16883220162 for example.

There are a handful of that desktop model so I'll try to find the one. How about this one?
"ASUS Desktop PC CM1740-US-2AF A6-Series APU A6-3620"

Unfortunately Asus USA seems to not have this one on file.
This looks to be a desktop from 2012 so let's wing it.

From what I can tell they used this board:
https://www.asus.com/Motherboards/F1A75M/

Manual is at https://www.asus.com/Motherboards/F1A75M/HelpDesk_Manual/

This can also occur if the owner isn't cleaning the fans and inside on a regular basis.

Thanks for reply

Thank you for the reply the f1 does work and allows me to enter the bios i reset it to defaults settings and double checked to make sure the system was not overclocked.Then it happens again the following morning. Also i have never touched the jumper pins they are on pins 1-3.

That helps. To me this tells me

It's time to replace the CMOS battery. It's old enough. Cheap too. I pay a buck on amazon.com but buy in bulk.
