Ok mate what browsers are you using besides the Comodo in your specs which are really very brief to work with.

Now I notice you only have 1GB RAM in that machine and it is really not enough to run the machine properly in reality you should have the absolute minimum of 2GB and more realistically 3-4GB as the more you have the faster your programs can load.

Internet explorer, chrome, firefox, or chrominum they all do the same not on all sites just a few

That is the CMOS battery dying. You will need a CR2032 battery to replace it which should be readily available.

There is a need to take note on the BIOS settings before replace.
Most setting may use the default.
This is that currently you do not have any problems.

Yep well Eric and TH are probably on the money because your computer is of some vintage the loss of the charge cause things like date and time to fail for example. Some newer machines have the capability for the BIOS firmware to maintain the settings and this is a bit of info for you https://en.wikipedia.org/wiki/Nonvolatile_BIOS_memory#CMOS_battery

@casscass

When you do the replacement, you must be very fast to push in the new coin battery.
Then the BIOS setting may not change.
After replacement, you need to go to the BIOS to check, again, the Date & Time.
If you able to do it fast, the Date & Time will remain as current.

As i had done this several times.


***Off topic***

Date and Time are most important.
I did encountered this on the Android phones.
Trying to update the apps, it failed, as some phone setting for date/time will zero.
