Adsense ads dont display on the index page

On my laptop but OK on my desktop PC

[Gian04]

Here is my problem:

All sites (not just my sites) that I will visit using my laptop, with adsense on the index page, it only shows a white space in place of the adsense ads.

Im very much sure that those sites has adsense on their index page because the ads shows without any problem if I open it using my other PC.

I dont think its my laptop's browsers setting because if I browse through the sites other pages, its adsense ads displays without any problem.

Any idea whats wrong with my laptop, why it doesn't display adsense ads on every index page. I have already tried turning off my antivirus and firewall, but still the same.

Hobbs, it doesn't answer my problem.

First, its only only the index page of EVERY sites (not just my sites) that I cant see adsense ads but if I browse through the sites other pages, it shows adsense.

Second, I dont have that problem if I am using my other PC to visits those sites.

but did you check your hosts file as a possible solution?

If it is only on one cpu then my guess is something is wrong with that cpu specifically
