Google Chrome

my PC slows down when I am looking at multiple web pages.

I'm using google chrome. A few weeks ago, my BT modem crashed, so I re-booted it.

Since then, when I've had the PC switched on for an hour or more, and when I've got a few different web pages, the whole PC slows down. I re-booted the modem again and it cured it for a while, but after a while slowed down again.

I have run avast and malwarebytes a few times each, I have no virus or malware.

Any advice would be appreciated. The PC isn't new but isn't that old either, the spec should be fine, it has been fast enough for a long while now.

Is it the PC slowing down or the internet connection slowing down?

I am not sure. I am getting pages that need to be killed, and it also slows down switching between web pages and word docs, for instance too.

It is usually fine for a while after I boot up the PC, then starts to slow down either after a period of time o r when I try to look at more websites, this has not been the case until a week or so ago.

I have emptied my cache, browsing history etc a few times to try and improve it.

When was the last time you defragmented your harddrive? How much free space do you have? When was the last time you cleaned the dust out of the computer? Laptop or desktop?

i haven't defragged the computer for about 18 months...

It is a desktop

I'm using 62 gigs and have 187 gigs spare space

Run the defrag routine on your harddrive. Also take a flashlight and look thru the grill in the back of the computer and see how much dust is built up inside the computer. Let me know how the defrag goes, and about the dust.
