Hp Pavilion 23 Blank Screen With Mouse Cursor After Hp Logo (Not Windows Logo)

Hello my computer wont start up all i get is a black screen but i have a mouse cursor. after a little bit the computer will restart and do a automatic repair but nothing happens it just keeps on rebooting. i tired to do a bio update but it seems to not be working. there is no option in the bios to update or even in UEFI. i also did a harddrive test and got a Short DST Check fail (FAILURE ID: 909HVX-0007K0-WPU2XF-60WH03) but i still can get access to the harddrive using a Linux LiveUSB and all files are there. (Product Number Is : H5P60AAR#ABA)

It is possible to receive a false DST check but not common.
It doesn't mean your hard has failed but that it is in imminent danger of failing.
You can try again but this time using the Extended DST test.
But before doing anything I suggest you back up all your important data using that live Linux boot disk just in case.
Every hard disk manufacturer has their own diagnostic boot cd/usb. Google it.
You should create one and run it for your brand hard drive.
You should be able to determine which brand you have from the BIOS/UEFI hardware tab.
While your'e in there double check that your boot priority is set to hard drive first.
Your other issue seems to be the dreaded 'Automatic Repair Loop' which could be caused by your possibly failing hard dirve. I would fully diagnose the hard drive first.
Here's a link with several suggested fixes. Some of them require a Windows 8 boot disk, other do not.

After upgrade to Mavericks, a new gray screen appears just before the regular login screen. The new screen appears for a few seconds with several boxes full of unidentifiable figures. How can I remove?

OS X Mavericks Upgrade Issue
Now when I boot my iMac, a new gray screen appears for a few seconds following the Apple screen and just before the login screen. The new screen shows several boxes with unidentifiable figures in them. It has become annoying because it has never appeared before. Anyone know of a way to stop this screen (of garbage) from showing? Thanks…Larry

It's possible that a PRAM reset may solve the problem:

When on some website pages, the page disappears after a few seconds and a blank screen appears.

When clicking on a link in some web pages (AARP in this case), the web page loads in a separate tab, and after a few seconds the page is replaced by a blank page and the word "done" appears on the second from the bottom bar on the screen.
I have updated Windows XP as of 9/15/10 and Firefox to version 3.5.12, but the problem persists.

Try to reset the phone by holding the sleep and home button for about 10sec, until the Apple logo comes back again. You will not lose any data by resetting, but it can cure some glitches.

HT1366 My MacBook OS X version 10.6.8 is not going to sleep, keeps loading, then when turned on a blank screen appears, I shut it and the main menu comes up and then it takes awhile for the cursor to operate. Thanks

My MacBook wouldn't go to sleep, it keeps loading, so I have to turn it off. When I turn it on a blank screen comes on, I shut the lid and open it and the main menu screen comes up but the cursor won't work for awhile. Then, eventually, the cursor will work and everything is fine. Hmmm?

Black blank screen appears when unlocking iOS screen

Hi!
I am developing and Adobe Air application for iOS. I have the following issue. If I have my app open and lock my iPad and then unlock my device, I see a black blank screen instead of my application contents. In order to make the app work again, I need to press the home button, and press the app icon again. Then the application appears fine from the point I had left it before locking the device.
Any suggestions on how to fix this issue? I use Adobe Air for iOS 3.8
Thanks a lot.

I was able to fix it:
I tried this ANE http://forum.starling-framework.org/topic/ane-fix-for-blackblank-screen-bug-when-returning -to-air-android-apps
After some testing I noticed, that the mentioned manifest-flag "<containsVideo>true</containsVideo>" does the job for me on his own...

Bootcamp 5.0 installation: Blank Screen with blinking cursor after restart

I have a late 2011 mbp with 16gb ram, 2 750gb hard drives. I'm trying to install bootcamp on the 2nd hard drive. I'm using the cd drive in an external usb housing to install windows 7 ISO burn. I've used this cd several times in the past with no issues. After creating the partition with bootcamp assistant, my mac restarts automatically then when it boots, it goes to a blank black screen with a blinking cursor. I have restarted and repeated this process several times, as well as let it set there for about 1 hour and still nothing...I've also tried sudo ram reset and command option p r but still nothing.
Anyone have any idea what's wrong?

Ok guys, for those of you who are having the same problem...here are the instructions on how to get past the blank screen and install windows 7 bootcamp with TWO hard drives installed.
1. With both hard drives installed, start the bootcamp assistant (you need a usb optical drive with windows dvd inserted to do this). Partition your SECOND hard drive for windows.
2. When your computer restarts and your at the blank screen with the blinking cursor of doom, manually shut down your computer.
3. Remove both hard drives from your MBP. Put the "Bootcamp" partitioned hard drive in the main HD bay. MAC OS DOES NOT NEED TO BE INSTALLED ON THE "BOOTCAMP" HD TO DO THIS.
4. Install your optical drive back into its factory place. (Where the "BOOTCAMP" HD was just installed at)
5. Power back up your MBP while holding the alt/option key down. Make sure the windows DVD is still in the optical drive!
6. Click on windows cd to boot from.
7. Start installing.
8. When finished, replace optical drive with "BOOTCAMP" HD and put MAC OS HD back in like it was before this process.
9. Your finished.
10. Now enjoy!

This is not what happens. The screen goes black, no curser or anything, then it comes right back on to the same page I was on when it went out. It doesn't happen when I login, it happens as I am on a webpage or playing a online game.

CP4 - blank screens appearing as quiz questions

Hi - I am using Captivate 4 & I have a question pool of 65 questions. My quiz is defined to display 40 of these questions.
Sometimes when the quiz runs, a blank screen will appear instead of a question slide. It can happen anywhere within the quiz. The play bar appears at the bottom of the screen, so it appears as if a question is being displayed... but nothing appears on screen. The only way to get past the question, is to click the forward button on the playbar.
It doesn't happen *all* the time, but I haven't been able to pin down if it is happening for a particular question or not.
Anyone run into this?
help?
thanks - Monica

I am getting the same thing in my one of my recent projects, while doing the quiz sometimes there is a blank screen and it locks up? although at least 20 people have completed it successfully, I am now getting messages from others who are saying that the quiz is not working.

Hi ausrius517,
Sorry to hear you are having a problem with your device.
Have you tried performing the following resets to see if it will solve your issue:
Soft Reset - this will not delete and data off your device.
Enter *#7780# into your phone's keypad and when prompted, enter 12345 (default code)
If there are not too much data on your device and you have made a backup, you can go for the hard reset option below.
Hard Reset - this will wipe all data off your device, so a backup is recommeded before doing this.
Enter *#7370# into your phone's keypad and when prompted, enter 12345 (default code)

haZey
