Compaq V4440US clock runs slow, sometimes stops completely, this causes email program to fail to work as needed sometimes.

Hi Sally.
I am assuming you are asking about Cortana.
Cortana is a voice activated personal assistant that you can use to get Weather forecasts, remind you of appointments and/or dates, send email, Etc. A lot of people find this program helpful, and a lot of people find this program annoying, ( BECAUSE IT SLOWS THEIR COMPUTER DOWN). You can disable this program two ways: 1st way, launch Cortana from the search bar on the task bar, click settings from the left pane, and under Cortana the first option I believe, slide the button switch to the off position; 2nd way, type gpedit.msc in the search box to open the editor, go to Local computer policy/ Computer configuration/ Administrative templates/ Search. Then double click the policy named allow Cortana. I believe this is it for the second way. Hope this helps. Let me know.

I've (also) recently experienced more than the usual amount of "clocking" when checking yahoo mail ... i.e. system busy icon ... which doesn't enable you to do much else.
When the "clocking" is shown, the system is busy because it's doing something else in the background. Sometimes, it's downloading stuff - something else, like software updates, ad's, pop-up screens, images & videos for ad's, etc.), updating previous webpages, checking for updates to software (on your computer), and/or running some (other) programs ... which may include spyware, ad-tracking software, malware, security / virus scanning applications, etc.
Yes, yahoo mail downloads a lot of "junk" (advertisements) ... particularly since it's a free tool. One way to reduce this volume of downloads is to set your browser to not accept pop-ups, to only accept cookies from the webpages you visit, to not store or update previous webpages, to delete old webpages (from history), to delete (internet-temporary) cache when closing the browser, and to delete your cookies ... just to get rid of ad tracking cookies that spawns processes/apps that bring down other advertisements related to what you've been doing/searching, viewing, etc..
If yahoo mail is not responding (e.g. mail server is slow), it will display a message accordingly. And the "clocking" won't last long. Sometimes, your system slows down because it retains lots of "old" or "temporary" stuff and/or your disk is quite full and/or fragmented causing it to take longer to access data/files, and/or your registry is cluttered up with un-used stuff. In such a case, it helps to clean out the "junk" (e.g. using CCleaner ) and de-frag your disks (regularly).
Sometimes, it helps to shut down and boot the system again (after cleaning out the junk, etc.)
Some may even suggest you get a faster processor, a faster internet connection and/or a bigger disk ... ;-)

My brakes failed sometimes while driving short or long distance

No driver information, no warning lights, nothing.

The brake pedal pressed until then only the vehicle will slow or stop.
The service man already re-bleeding the system but the problem still exist. Therefore, what cause of the problem.

I drive a 1.7D GSE in Ireland. This car is less than 6 months old with 10,000 KM on the clock.

Not happy.

First Step:
It is more likely that scripts are having issues running on your computer. To correct this you need to Download Windows Script 5.6 depending on your operating system.

Second Step:
Undo damage that might be caused by a virus

You mean the image has loaded completely, but only in a 1/2 window? Or the image stops half way through loading? If the latter, then maybe check the DNS setting.. Sometimes the ISP changes it without notice, but if it's the latter it's quite odd. Might need more info, eg can you ping your isp? Are you running other programs, does email work ok.. etc
