OptiPlex 745 sometimes freezes on the start of start page

I recently put the hand on one occasion Optiplex 745 (CPU Intel of E6400 @2. 13 GHz, 2 GB RAM), which seems, to an almost complete lack of internal dust, were very little used.

It works perfectly except the problem that is described in the title of the thread. When he turned, 'sometimes' (maybe 2 out of every 3 attempts), the screen freezes on the start page to start Dell with the stop bar (between Optiplex 745 and BIOS 2.6.6) progress before the end of his race.

It seems if stop is at half way through (under the '7' in Optiplex 745) or after only 25% of his race.

It is interesting that he stops, apparently, exactly one or the other of these two points each time.

Immediately after, if I turn on the machine, then next turn, it will start perfectly about 95% of the time. Otherwise, I might have to stop/resume a third time so he can begin.

While Google has found countless instances of computers to freeze while displaying the boot splash, everything I've come across seem to have problems 'permanent '. In other words, the start is just not possible. In my case, however, I can start and the machine seems to work perfectly as the occasional glitch.

Can anyone shed light on what could happen here? And should I be worried?

Hi Ron

Thanks for your suggestions. Yes, I would have given more information in my first post. In fact, the form factor is LTS, the power button remains lit in green before, during and after the freeze, the diagnostic lights 1, 2 and 3 turned ("another failure has occurred") and no beeps sound. I don't know when the cmos battery has been replaced last as I have only had this machine a little over a week ago.

However, it seems that the problem is now solved, but note that I did say that I understood why it is resolved.

I did a lot of fiddling around trying to get this little machine works well. When I finally got in some OS (dual boot Win7 and Ubuntu) installed on the HARD drive, I had two sets of wireless keyboard/mouse hooked through dongles usb - not intentionally, but it's what happened.

That is when I started noticing the problem described in my first post.

As I need a keyboard and mouse to another computer, I removed the dongles (it had a single dongle for kbd and one for the mouse) and, subsequently, I have not had one instance of the problem freeze despite having started the machine at least 30 times since then.

A test, I plugged two dongles of kbd/mouse as before all leaving the single dongle for the other connected keyboard and mouse set. In this case, the start is frozen in two of the three attempts.

In order to have both sets keyboard and mouse attached seems to be the problem.

But why? I'm puzzled.

  • How to disable the start page promotions?

    Whenever I start Firefox, I am taken to the Start Page of Mozilla Firefox.

    By default, the page displays the Firefox logo, a search bar and the footer of downloads, bookmarks, session of previous restore button button, etc. However, Firefox logo occasionally goes to a "promotion" of all kinds, things like FoxYeah or more recently some videos, and a line of text speaks of promoting appears under the search bar.

    Is there a way to disable these promotions?

  • Firefox crashes when you try to locate a Web site to the start page

    Hello.

    Whenever I try to pin a website to the start page, Firefox crashes. Research in newspapers, I see:

    E/GeckoCrashHandler (11176): android.database.sqlite.SQLiteConstraintException: failure of the foreign key constraint (code 19)

    I'm on CyanogenMod 10.2.1.3 (4.3.1 Android) on a Samsung S4 Mini (GT-I9195).

    Does anyone have any ideas on how to solve this problem?

    Thanks again pwzapp!

    I'll have to ask our developers and other techniques

    It is perhaps related to this bug:

    The only thing I can say at this point is to try Firefox 38 beta version of the game store (or wait until that Firefox 37.0.2 comes out later this week or early next week)

    See you soon!

  • Start Mozilla Firefox changed yesterday my page. It is heavy. How to get back the start page I had before?

    The new start page fills the entire screen. It is the slider against the top margin to reveal the bar showing the tabs and the 'X' to close in the HR area. Inside, the start page covers the box 'Start' and the information on the bottom row. Now, I can't click on bookmarks - I have to click on the logo, then use the side bar to access the bookmarks. I also lost the ability to switch between the net and the document I'm trying.
    This new configuration may be suitable for some people, but the previous one was simpler and better for me. How can I get it back and prevent the update again for this version of Firefox?

  • How to delete the history in the drop-down menu search in the middle of the Start Page?

    I deleted the whole history using clear all and restarted FF. The drop-down list search in the middle of the Start Page always displays all of the research I did in the past to him. How can I remove this from this search bar?

    What is the URL of the start page?

    You can remove the formhistory.sqlite file in the Firefox profile folder to delete all stored form data.

    You can use this button to go to the Firefox profile folder:

    You can delete all data stored in Firefox with a specific area through "Forget this Site" in the context menu of a history entry ("" history > view history "or" view > sidebar > History "") or via the subject: permissions page.

    Using "Forget this Site" will delete all data stored in Firefox in this area as bookmarks, cookies, words of past, cache, history, and exceptions, so be careful and if you have a password or other data from this area you don't want to lose so take note of these passwords and bookmarks.

    You can't recover from this "forget" unless you have a backup of the files involved.

    It has no lasting effect, so if come back you on such a 'forgotten' site, then the data of this Web site will be saved once more.

    I currently have Firefox 9.0. Why the start page for firefox keep telling me that I don't have the latest version?

    You may need the old start page. Go to Firefox > Options and in the pane general, under Startup, click on restore by default. The page you have probably (http://google.com/firefox) only served to 3.6 (and tells you you are outdated), but some users seem to have gotten stuck on it after updating to Firefox 4 or upper version.
