Blue Restart Screen Has Appeared 4 times in One Day

Today the Blue Restart screen has appeared four times and while each time it has successfully restarted, it is becoming quite annoying. Also, I'm losing work though I've been lucky enough to save at good times.
Does anyone know why it would appear this often? Is this a hardware or software problem? What can I do to diagnosis it?
Best,
David

To identify problem, please use eventvwr in windows . Go to computer then system , filter critical errors! Check for the one that causes a restart. If it's a software please reinstall , or update your drivers . THANKS
KUDOS if it helped

Small black box on bottom of screen

Enter Passcode screen has appeared

All of a sudden this morning my iPod is asking for a password and I have not set one up! In the past I have used the passcode lock in the Settings menu but not for some time. The screen that has appeared now is a different one to the Passcode lock screen and entering the passcode that I used to use does not work. I've tried turning on and off but no joy. Any ideas?

If you have screen-lock passcode screen (you can have two, on for a simple passcode and the other where the keyboard one comes up), connect the iPod to its syncing computer and retore via iTunes. If iTunes asks for the passcode and you can't enter the passcode, place the iPod in recovery mode and restore via iTunes. For recovery mode see:
iPhone and iPod touch: Unable to update or restore

I have this empty black box in middle of screen with cursor in it after upgrading from SnowLeopard to Mavericks - any help???

Ipod 4 gen black mark in corner of screen, why is this?

Why does my 4 day old i pod touch 4 th gen have a black mark in the corner of the screen

Could you have dropped the iPod or place a lot of force on that corner?
Is the mark on a viewable part of the screen?
You can make an appointment at the Genius Bar of an Apple store and have it checked out..

When 40+ tabs are open, black boxes start randomly covering screen

This is a weird one, and I couldn't find anything describing problems like it elsewhere.
If I have about 40 or more tabs open, black stripes and blocks start covering the screen. If I move my pointer, they start forming more where the pointer goes. After maybe 30 seconds, if I move my pointer, the black areas go away where the pointer goes. Sometimes if I do nothing, all of the black areas go away on their own. It's almost as if Firefox can't render the page and it takes it that 30 seconds to regain the ability to do so. Bizarre!
Anyone have any ideas?

Hello rch427, try '''disabling graphics hardware acceleration'''. Since this feature was added to Firefox, it has gradually improved, but there still are a few glitches.
You might need to restart Firefox in order for this to take effect, so save all work first (e.g., mail you are composing, online documents you're editing, etc.).
Then perform these steps:
#Open Firefox ''Options'' window as follows: click the menu button [[Image:New Fx Menu]] and select ''Options''
#In the Firefox Options window, click the ''Advanced'' tab, then select ''General''.
#In the settings list, you should find the ''Use hardware acceleration when available'' checkbox. '''Uncheck''' this checkbox.
#Now, restart Firefox and see if the problems persist.
Additionally, please check for updates for your graphics driver by following the steps mentioned in the following Knowledge base articles:
* [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]]
* [[Upgrade your graphics drivers to use hardware acceleration and WebGL]]
Did this fix your problems? Please report back to us!
Thank you.

A passcode screen has appeared, but i didn't set one up

the 'enter passcode' screen is blocking me from using my ipad. i didn't set it up, what happened and how can I disable it?

i use gmail on my iphone and ipad, but neither device has ever locked me out like what just happened with my ipad. i was just trying to access my apple id to setup icloud on apple.com when i was having difficultywith my primary email. so i attempted to change my id to the gmail acct, and now this happened. i don't know if there is any connection, but it is strange that it happened afterwards. if i restore from itunes, will i lose my ipad data?

TS1502 I have an ipad and a blue screen has appeared.....what should be done to get the ipad to work again.

My ipad is displaying a blue screen. I have tried to reboot but nothing is happening, it keeps displaying the blue screen. How can this be fixed so I can use my ipad again

Try this - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.)

Transparent Black text box? HOW???

Normally i am pretty good at figuring out these things but
this has been driving me crazy.
I was viewing a website a while back that had listed
emergency information with white text within a transparent black
box that allowed you to see through the box itself to the webpage
below while still reading the text. How is this done? I have
fireworks 8.

Found it!

Macbook Pro Black boxes across screen then crashes

I have a Macbook Pro that I got 2 months ago. A couple days ago it froze and had black boxes all across the screen, then it crashed. Today when I started it up after I logged in while it was loading the black boxes popped up again, then it crashed. And when I tried to restart it it just beeped. The battery was around 50% so it wasn't dead. Its been fully updated and I haven't made any changes to it. Please help if there's anything I can do without taking it in

T60 menu text has disappeared/now black boxes

Can anyone help me figure out why my menu text turned into black boxes on the display screen.
The last thing I did was to change my screensaver. I had a screensaver called "Royal remixed themes" I removed that screensaver and ever since, I've had this problem. I'm unable to access any of my programs as the black boxes are not readable.

my model is T60 200756U
Unable to post a picture.
My screen shows my screensaver and desk top icons on the left hand side with proper colors, however, the desktop at the bottom of the screen is black and unreadable. I can't type in the info box or read any highlighted texts. It is very strange. On IE pc freezes. there are colored small icons in different places on the screen. I cannot type any www. as the menu bar is black
Thank you for getting back to me on this post.

This black box is making noise--what is it? (pictures)

I know there have been several threads regarding the white noise given off by Motherboards under heavy load. I also have a K7N2G-ILSR and it has made the noise since day one. Like others, I have tracked the noise to the little black box just above the mosfets near the CPU.
When I press on it, the pitch of the noise varies. Ideally, I would like to strip the tape from around the box and hot-glue the entire thing, but I want to make sure it won't hose everything. I don't care about the warranty, but if I can't make the sound stop, I'm liable to kill someone.
I would like to know what the black box does and if anyone has any luck silencing the sound!
Thanks!

In this case it stores energy and timely releases it, In MSI's words, this is normal, as the environment is high frequency.
To elaborate further on what I said before, what's likely happening is some of the components or that choke may be at the bottom or top of the allowable tolerance for manufacture. All electronics are not EXACTLY the same as far as components go. This is what's referred to as "parametric differences." You have the PCB, (printed circuitboard) CPU, RAM, peripherals, power supply, and, add to that, all the components that populate a PCB. A PCB is used on your VGA card, RAM, power supply, and ALL of your peripherals. All of these parts are manufactured with allowable tolerances, same goes for the PCB. Get the idea? See how this becomes an environment where things can easily get out of hand? Couple that with the fact of how many possible configurations can take place, and also that many of the componets and parts are manufactured by many different vendors.
Take a circuit board for example, you have multiple layers, dielectric in between those layers, the foil or copper layers in the internals are a set weight or thickness but the outer layers are usually plated up and/or etched down (this can include the internals). The etch process is done with acid, and you get a minute bit of what's called "etch down" where if you were to look at a cross section of a routed trace, you would notice that there is a slight "V" shape since the acid will etch around the sides. The board vendor must compensate for the etch down by enlarging the original artwork. However, it will NEVER be exact every time. The general specs for most of the boards we produce are +/- 20% of the original artwork supplied in the design data. That is, if you have an .008 thousandths trace, we can be within .0016 of the original.
Granted some tolerances are tighter when manufacturing high speed and impedance controlled designs, but you get the idea.
Now, you have basically the same scenario when it comes to components as mentioned previously. That is why you see users reporting strange behavior, mind you, it's a small percentage, but it is generally exacerbated when multiple parts, components, and peripherals operate in a high speed, high frequency environment like today's performance PC's. It only takes a few things to be at the top or the bottom of a tolerance to create this anomaly, or another issue altogether.
This is what I know personally through my experience as a PCB designer and manufacturer, and then being in the electronics and IT industry, and of course, an enthusiast
