Sleep mode randomly?

[Brownfield1995]

All of a sudden today my desktop running win 10 on a fresh install about a month ago and it just goes into sleep mode suddenly and randomly. No more than 2 mins and bam sleep mode. And as soon as 5 seconds sometimes after I log in it sleeps.

check in your power settings to see how long it takes for it to go to sleep.  I set mine to never.  personal prefrence

Try 

Control Panel > Power and Sleep > Additional power settings > Choose when to turn off the display > Change advanced power settings > Restore plan defaults

Also make sure that there is no sleep button being pressed or something
