For quite some time now my clock gets set back every now and then. At first it was about an hour back each day, and a synchronize with one of the time servers fixed it.
For the last couple of days however it's being set back an hour every hour that passes or something. Which makes it quite annoying.
When I turn my PC off for the night and turn it on the next day it will be set back by a couple of hours (about 5-10).
The first thing I can find online is that the battery on the motherboard has probably run dry. However the PC is only a bit more than a year old and there are no messages on startup (normally the motherboard will give you a notification if the battery is low).
Furthermore the PC is always connected to electricity, and I think it doesn't have to use the onboard battery that way...
I have tried changing the internet time servers, turning it off and on but no result so far.
