Computer clock seems to lag?

[eknirb]

I have a digital clock that is synched with time.gov. but the PC clock always seems to lose seconds compared to it.

Probably your cmos battery. Check it and/or replace

check or replace? how is this done, is it easy? PC is exactly 1 yr old.

If just under a year, probably still under warranty. If more than a year still under warranty if you bought a contract.

You lucked out this time. Give them a call and let them earn that premium that you paid.

Is it losing seconds or has it always been behind?

If it has always been behind, go to "Adjust date/time", Internet Time, Change settings, Synchronize with an Internet time server, Server: time.windows.com or time.nist.gov.
Press Update now. Press OK.

If you've already tried that, then changing the battery, as suggested would be the next thing to do.
