I have a few problems with my laptop, which is running Windows 7 home premium. Sometimes when I boot up and create a document I notice that the system date has been changed to two years previous. I didn't revert to a backup or anything, I'm not sure why the date changed without any messages or error warnings.

 

Occasionally my system slows down for no reason, freezing up briefly and taking longer to process things even though there are no background programs running. It does this while working on simple text documents or my bookkeeping software, nothing that would consume an unusual amount of RAM. At the same time, my internet connection slows down or drops out, while my partners connection (same network) is working fine. Disconnecting from the internet, waiting then reconnecting sometimes helps.

 

I have the current version of Norton 360 which is up to date. Not sure why my system would become unstable while connected to the internet if virus scans are coming up clean.

your CMOS battery is flat, which stores the date and time etc, so every time you shut down your machine it reverts to original time.

 

it should be easy to replace even for a novice, who knows how to use google. (if you have and old computer lying around just grab the old one out of there, they often last many years)

 

If your machine is behaving in a random manner there could be probably is deeper issues besides the CMOS battery. 

 

There is a great "Am I infected" forum here in BC where you could find out more about that, though the likelihood of other hardware failing on your machine increases with age...

or it could just be a virus playing havoc with your system...

 

I'd go down to "Am I infected" and have a chat with those guys.

My machine doesn't revert back every time I boot up, just a few times I have noticed the date has changed itself. Norton isn't picking up anything, what kind of hardware issue would cause this?

CMOS battery is running low can cause intermittent date resets... so can malware.

Just read on it, and I found out that low CMOS can cause all sorts of gremlins as it boot system settings and stuff also. (I thought this, but didn't know it for sure before)

 

It's a cheap and easy fix on a desktop, getting your laptop apart might be more difficult though, might not also depending on your make and model.

 

Google is your friend.
