Processor failures can be have inconsistently.  I have seen processor failures start with 1-2 second hangs in the OS to working one day and not at all the next.

hey mate.. ive got the same issue.. is it an issue with the cpu.


The blinking code you have desribed is a beep code of one.  Review the following table found here.


Caps Lock/Num Lock 1 CPU CPU not functional Reseat replace CPU.


Caps Lock/Num Lock 2 BIOS BIOS corruption failure Restore BIOS from onboard backup (jumpers)


Caps Lock/Num Lock 3 Memory Memory module error not functional Reseat memory modules (see next section).

Test memory from UEFI or BIOS.

Replace bad memory modules.


Caps Lock/Num Lock 4 Graphics Graphics controller not functional Service
Caps Lock/Num Lock 5 System board General system board failure Service
Caps Lock/Num Lock 6 BIOS BIOS authentication failure Restore BIOS from onboard backup (jumpers)




The options for a blink code of 1 is to reseat the CPU as you have already done or to replace the processor.  Since the issue returns after reseating the CPU, it looks like the CPU needs to be replaced.

Mobile-first Indexing – most people are searching on Google using a mobile device.

Mobile-first Indexing

Friday, November 04, 2016

Today, most people are searching on Google using a mobile device. However, our ranking systems still typically look at the desktop version of a page’s content to evaluate its relevance to the user. This can cause issues when the mobile page has less content than the desktop page because our algorithms are not evaluating the actual page that is seen by a mobile searcher.

To make our results more useful, we’ve begun experiments to make our index mobile-first. Although our search index will continue to be a single index of websites and apps, our algorithms will eventually primarily use the mobile version of a site’s content to rank pages from that site, to understand structured data, and to show snippets from those pages in our results. Of course, while our index will be built from mobile documents, we’re going to continue to build a great search experience for all users, whether they come from mobile or desktop devices.

We understand this is an important shift in our indexing and it’s one we take seriously. We’ll continue to carefully experiment over the coming months on a small scale and we’ll ramp up this change when we’re confident that we have a great user experience. Though we’re only beginning this process, here are a few recommendations to help webmasters prepare as we move towards a more mobile-focused index.

  • If you have a responsive site or a dynamic serving site where the primary content and markup is equivalent across mobile and desktop, you shouldn’t have to change anything.
  • If you have a site configuration where the primary content and markup is different across mobile and desktop, you should consider making some changes to your site.
    • Make sure to serve structured markup for both the desktop and mobile version.

      Sites can verify the equivalence of their structured markup across desktop and mobile by typing the URLs of both versions into the Structured Data Testing Tool and comparing the output.

      When adding structured data to a mobile site, avoid adding large amounts of markup that isn’t relevant to the specific information content of each document.

    • Use the robots.txt testing tool to verify that your mobile version is accessible to Googlebot.
    • Sites do not have to make changes to their canonical links; we’ll continue to use these links as guides to serve the appropriate results to a user searching on desktop or mobile.
  • If you are a site owner who has only verified their desktop site in Search Console, please add and verify your mobile version.
  • If you only have a desktop site, we’ll continue to index your desktop site just fine, even if we’re using a mobile user agent to view your site.

    If you are building a mobile version of your site, keep in mind that a functional desktop-oriented site can be better than a broken or incomplete mobile version of the site. It’s better for you to build up your mobile site and launch it when ready.

If you have any questions, feel free to contact us via the Webmaster forums or our public events. We anticipate this change will take some time and we’ll update you as we make progress on migrating our systems.

I have been going to this spa already for almost 5 years. It is truly my favorite spot in the city. I love the fact that Juvenex is open 24 hours a day. It is very clean, they always serve you with fresh fruits and drinks, and the therapists are very attentive and very sweet. I normally get massages, facials and bikini waxing. Kim is my girl she does magnificent job to my skin. And her waxing skills are almost painless. She is one of my favorite therapists there. Also I get different kind of massages. The therapists really know what they are doing. Their magic and firm touch bring me back to life after long hours of work. I truly recommend this place. Never need to stay on line, the therapists are always ready to attend to your needs and they always provide the best service with a big smile and very professional courtesy.
