Computer randomly switching screens

I have had my computer for two months. The last week I have had a problem with the computer switching screens without my clicking on a site.
If I am deleting e-mail, it may delete two or three e-mails instead of one. If the cursor happens to rest over a link, the screen will go there.
I was on the Track Pad in Preferences to see what the setting were before this happened so I may have inadvertantly changed something I shouldn't have.
Thanks

I would take it to the Apple Store. Make a Genius Bar appointment. They have equipment and such to do hardware tests and things like that.
Genius Bar Reservations (they should not charge you anything unless they actually need to do work on it, if I am not mistaken).

CC aplications go to white screen and lock up the computer when switching between apps

We have been successfully using CC for several months, then about 30 days ago suddenly when we tried to switch apps between dreamweaver, and Photoshop the computer went to a White screen and froze. This problem is completely repeatable, and we are at a complete loss to correct the problem. Any ideas? It doesnt do this when you switch withing Bridge and Photoshop, but with anythign else,,,,,,,,,,,,,,, CRASH!!

I am unable to get into the chat. I tried explorer and chrome and neither will allow us to access the chat. It continues to go around and around.

MSI P35 Neo-F (MS-7360): Computer randomly freezes while playing games

Hi there,
I have reached the end of my technical knowledge right now and I'm not even sure if this area of the forum is appropriate. The problem:
While playing higher-end games like Crysis 2, Anno 1404, Mass Effect 2 etc. my computer randomly freezes and the last few milliseconds of sound are being looped on my speakers (kind of like a buzzing sound).
By "freezing" I mean that my computer becomes unresponsive to any action other than pressing the Reset-Button or holding down the Power-Up-Button (no reaction to Ctrl+Alt+Del, Alt+F4, Alt+Tab, no mouse movement... you get it).
There's no exact timing as to when these freezes occur. The fastest freeze happened after less than a minute of playing a game, slowes one (just today after switching to my newer case with better cooling) took about 2 hours.
This freeze only occurs while my System is under load. No freezes while browsing the web, using office programs, listening to music or watching videos.
System Specs:
Mainboard: MSI P35 Neo-F (MSI-7360)
CPU: Intel Core2Quad Q6600 @2.4GHz
RAM: 4x 1GB DDR2-800 Corsair XMS2
Graphics: Gainward GeForce GTX 560 Ti, 1GB GDDR5 VRAM
PSU: Antec High Current Gamer 620W (upgraded from Xilence XP600, 600W)
New CPU Cooler: Arctic Freezer 13 Pro (upgraded from OEM Intel Boxed Cooler)
New Case: Zalman Z9 Plus w/ 4x 120 mm Fans (Upgraded from a Case with only 1x 250mm side Fan)
2 Western Digital HDD (1x 2TB, 1x320 GB)
1 DVD Reader/Burner (unimportant for that error I guess)
OS: Windows 7 Ultimate 64-Bit
2 Screens: 1x 24" Asus VS248H and 1x 21" LG Flatron Wide W2240T
Since this error is bugging me for quite a while now and since this is not the first forum I'm trying to get help from, here's a list of steps i already took to get rid of it, obviously to no good use:
reinstalled games where the freeze occurred
updated all Drivers (including cleaning old versions in safe mode; also tried older drivers)
updated BIOS to v1.A0
Reinstalled Windows
bought new Case and CPU Cooler to improve Air Flow/Cooling
checked Seating of all components (took out, cleaned, reapplied thermal grease where neccessary, re-inserted)
cleaned old case of dust (obviously no problem in the new case, which is 2 days "old")
ran 7 sequences of Memtes86+ without any errors
ran Prime95 without any errors for about 45 Minutes
ran Furmark for 15 Minutes under full load (burn-in test) without any problems, even though my graphics card hit the 100°C frequency-cut level
ran Furmark and Prime95 simultaneously without any problems
took records of component temperatures and system voltages without noticing anything unusual (at least not after i switched to the newer PSU, which is about 1 Month old - yet didn't resolve the problem)
tested with cyclic removal of 1 RAM device to further rule out RAM malfunction
tested with only 2 RAM devices in dual channel mode (Slots 1 and 3)
tried to reduce RAM clock (800 MHz --> 667 MHz) to no avail
checked S.M.A.R.T. values of HDDs, no issues reported
tested without any background programs
raised/lowered voltages to RAM, CPU and Chipset in BIOS to increase logic circuit stability/decrease heat production
I need to mention: After I transferred my system to the new case, i was able to play longer than average compared to my old case. So I am guessing that improper cooling was part of the problem, yet improving cooling obviously didn't resolve it.
Since these freezes are really annoying and nobody could help me resolve this so far, I'm hoping to find some new ways of narrowing down the problem or even getting rid of it here.

Sebb

Lets be realistic. A system with a 560TI is recommended to have a around 31Amps under full load, a CX500 would be sufficient.
Have you monitored your CPU and memory utilisation ?
As suggested before, test the GPU in another computer to see if the behaviour is the same.
Whew, I thought for a second there that my common sense had left me when I saw that 60-Amp-Post ^^
Yes, I monitored CPU and RAM usage, there is no recognizeable pattern to be seen and it almost never happens under full load.
I will see if a friend of mine can test my GPU on his computer, and I will test it underclocked right away.
Though one more question regarding that: Should I only underclock GPU Core Clock or both Core and RAM clock?

Random black screen for 1 second, anyone have this issue?

hi, my macbook pro randomly switches to a black screen
reading threads on black screens, it seems its a common complaint
however I just got mine 2 weeks ago..should a brand new macbook be doing that?
or is it a commonly reported design flaw?
thanks!

I've experienced the same issue exactly as described, with the R7850 Twin Frozr OC Edition. However, I've also experienced a crash or 2 in which the screen goes black and the monitor goes to sleep. The computer doesn't wake up and I'm forced to do a hard reset. One such event was severe enough that I was unable to restore Windows 8 and had to do a full reinstall...!)
Everything is clocked at factory default, passes Memtest 86+, Prime95 overnight run, even FurMark successfully...
Board: ASUS P8Z77-M
Bios: American Megatrends Inc., v1708

When I tried to save the GPU-Z BIOS settings to a file, my computer crashed my computer (!)... Hopefully this is sufficient to indicate if I should follow the same steps or if this is a different issue / hardware issue / ???

(Perhaps worth noting that the box didn't include any driver CD for some reason)
Thanks for the help.

Apple IMac 27 has a problem. Random black screen. Over 1 year without any fix

Apple IMac 27 has a problem.
Random black screen.
Over 1 year without any successful fix.
IMac 27 10.8.4 (12E55) - bought in 2010
3.06 GHz Intel Core 2 Duo
4GB 1067 Mhz RAM
Graphics ATI Radeon HD 4670 256 MB
The IMac computer screen goes black randomly but the machine still running beyond.
In order to go back to normal i need to awake the computer by hitting with the pointer a hot corner previously created " sleep mode" ( top left ).
..the black screen would come back after one second again..and then again and then again and then again..with different intervals..sometime 2 seconds after the other, sometime as soon as appears the user login screen.
I took the machine to an Apple Store two times over one year, they opened, cleaned it but they didn't replace anything has they could not understand what they real problem was. I was happy for that because they didn't try to make me spend money on something which was not going to solve my issue for sure.
Last time i kindly asked them to inspect everything meticulously, part by part, i left the machine with them for over 2 months. They couldn't understand why this was happening..after couple of weeks, 5 more machines came in with the same problem.
On some of them., upon request of the client they changed the graphic card but apparently this was not the fix, the problem come back again. Apparently changing the graphic card or the screen or else it didn't solve any problem to anyone. I'm almost thinking to "trough it out of the window"..we all spend money for this machines and i think we need to know if Apple is looking in to this or not.
Lately i tried to do an SMS RESET and PRAM RESET, it feels it got better a little but problem still coming back.
Also, all usb devices are disconnected and the problem still there
Below you will see a copy of the console report. I honestly don't understand much of it as i'm not a computer guy.

I'm now thinking to try to take the machine to its original firmware and see if it still does it, does anyone have any sugestion?
I use a lot photoshop and other image software, this computer is essential for my work. For more then one year this issue caused me problems.
Luckly i have a Macbook Pro too and i managed to do some of my work there. At last I was thinking to buy an external screen and attach it to the Macbook pro in order to work on my big images. But who wants to spend money again!!!???? This is not a fixture, this is silly. I wish to have my IMAc working again.
The warranty it's obviously over and this problem happened right after the warranty was over...
I write this post because i'm so tired of this issue and online nothing can be found apart from posts from so many people that have the same problem and no fixture has been found.
The only fixture seams to be to buy a new computer... Ole'!!!..new money flowing in in the cashier!! forget it!!! i would rather change company if apple doesn't respond to this.
For over 10 years i have been a Apple owner..
When this problem appears it's like someone it's playing a joke at you...
Comments welcome..
Thanks

Hi, I've seem to have found out the source of the problem.
The issue is related to heat, and an iMac 27" gets hot pretty fast.
If I boot the iMac straight after first start into Windows 7 I seem to get a lit built-in display at all times. I can also boot OS X first and then into Windows 7 and the built-in screen get lit every time as long as the iMac isn't hot.
Strange thing is that the monitor connected to the display port gets lit every time. So I can only assume that the heat only interfere with output to the built-in LED screen.
So this iMac is going to an Apple premium reseller for service, and I'll tell you guys how it went.

Switch screen button in keynote 6.0

I had my first presentation today with Keynote 6.0. Everything was fine except at the conclusion I wanted to find out how to get to the other slides. I was checking the buttons at the top right and pushed what I now realize is "switch screen." Now what I should see on my computer (presenter view with slides) is what they see on the screen. I've looked everwhere and I can't find a 'switch screen'so that I can reverse it and when I'm in presenter mode, there's no way to find that. Any help would be much appreciated!

Thank you so much. I didn't know that shortcut and it fixed it right away. I was surprised that when I went back to the section that all of those slide were only a small portion of the page. It's almost like the white part of the slide got bigger so the actual slide information shrunk. Obviously I hit something in my frustration that changed the slide size, but luckily it will be easy to replace. Great response to my question and much appreciated!

How do I find out what is causing a random black screen on iMac?

Hello I get random black screen on a iMac and I haven't made any hardware changes. How can I find out what is causing this?
Thanks

You can do an SMC and PRAM reset. These won't hurt anything and 'might,' maybe help the screen issue. If it doesn't, then take it into an Apple store or AASP for their guidance and advance testing diagnostics.
SMC:
Shut down the computer.
Unplug the computer's power cord.
Wait fifteen seconds.
Attach the computer's power cord.
Wait five seconds, then press the power button to turn on the computer.
PRAM:
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

My computer Randomly reboots

I am trying to build a computer for my sister for christmas. I have everything up and running, except the computer randomly crashes. There seems to be no rhyme or reason to it. I can't reproduce the problem on command, sometimes it works for hours, other times it works for minutes.
crash = screen goes blank, monitor power saving light comes on, computer locks up, I have to unplug the power for 5 or so mins, and turn the computer back on.
First thing I though was the ram timings were set to fast. So i took it down to the spd levels. Didn't fix the problem
Then I thought the powersupply might be bad, so I replaced it with a more powerful one. Currently running a 400W +12v antec power supply. Didn't fix the problem.
Then I thought it could be an overheating problem. I know how to choose a good fan, and properly install it. I've overclocked several computer with lots of success. Although I'm not trying to overclock this one. Anyways, I installed a temperature monitoring program, and the temps never get above 54C under full load, even after several hours. Also the computer crashes during non intensive computing times, IE: word processing.
I thought maybe it was a video card problem, so I uninstalled the video card drivers (ati 9200) and installed a gf4 ti 4200, and installed the latest nvidia drivers. Didn't fix the problem.
I then figured I had bad ram or a faulty cpu. I returned the ram and the cpu and bought new ones. Didn't fix the problem.
I updated my bios, and this didn't fix the problem.
I have windows xp pro sp1 installed and all critical updates. I have the inf files installed for the chipset, the newest sound, video, net, etc drivers. Didn't fix the problem.
I don't have any crazy software installed, just windows and office + updates + virus scanner.
I formated the system, reinstalled all software, and drivers, started crashing before I could finish downloading the windows updates.
the mother board came with the device that sits in an expansion slot with some led diagnostic lights on the back. There are 4 lights, and they are normally all 4 green. When the computer does its crash thingy, the lights numbered 1 and 4 turn red. According to my motherboard manual this means "processor initilization"
Specs:
Msi neo2 865pe
intel p4 2.6 800mhz fsb HyperThread turned on
2x256mb Kingston pc3200 cl2. (khx3200ak2/512) (dual channel on)
Ati Radeon 9200
Maxtor 40 gb 7200rpm ata133
antec 400w +12v power supply
I'll be happy to provide you with any info necessary to help me fix the problem.
Thank you,
Colapser

There is an option in BIOS to enable or disable HT.
I know that you've bought a HT enabled processor for the HT support, but just try and see if the problem is solved 1st before seeking out some workarounds to get HT enabled problem free .

I cannot switch screens on my Apple TV

I marrying to switch screens between using the iPad on Apple TV and the remote showing the icons

Same here! Just a few days ago it started. Nothing will play from the cloud. Browsing the store works, streaming from a computer works, airplay works. Just none of my tv or movie purchases in the cloud.
I've reset it a few times. Ran the network test and it's passed every time. I've tried setting static ip and DNS info to no avail. I'm clueless. It almost feels like my ISP is blocking it but that's crazy talk.
Anything else to try? Tomorrow I'm going to hook it up to Ethernet and see what happens. As of now though, this is a mystery.

Not smooth when switch screen on my RMBP

I upgrade my Retian Macbook Pro to OS X Mountain Lion and I found when I switch screen it is not as smooth as it used to be when the computer is running with the Intel graphics 4000. It's kind of dazed for me when switching to wallpapaer. It became better if I choose to use the GT650M but it will use more power. Anyone have the same feeling?

You can still do it with CONTROL + Arrow keys, the same as 10.6

MSI N750Ti TF 2GD5/OC, random black screen from hdmi output

Hi,
Bought a MSI N750Ti TF 2GD5/OC and connected it to two monitors. My main monitor is connected to the hdmi port, and the other to the DVI one. I get random black screens on my main monitor. They last about 3-4 seconds, and my secondary screen just runs on happily. Unfortunately the latter screen doesn't support hdmi, otherwise I'd simply switch the outputs to see if it's the monitor or the card. However, I do suspect the card because I can 'break' or trigger the black screen by manipulating the hdmi cable at the card's output.
Anyway, is this a known issue or should I experiment a bit more? If it is know, what's a good solution?
I did update my drivers, btw.
Cheers!

what do you mean by this?
That I only have one monitor with an hdmi input.

have you tried different HDMI cable? or/and different display with HDMI?
Will try a different cable, and see above.

The screen on my iPhone 4 turned black while i was using it-it was not dropped or damaged in anyway. The phone itself is still working as it comes up in itunes when I plug the phone into my computer, but the screen is completley black. What can I do?

The screen on my iPhone has gone black while I was using it. It just "shut off". The phone is still working as I can hear/see it when it plugs into the computer, but the screen just wont turn on. I've tried the soft reset "holding down home and lock screen" and i've tried to restore settings. I went to the apple store and they said I had to send it to my provider (in another country) but my phone contract has run out.
Is there a way to fix this?
If not, is there some way apple can replace the phone? It's less than 2 years old. Surely the screen shouldn't just give out like that.
Thank you

You did install the latest iTunes (10.5) right? If the problem was that iTunes does not see the iPod try:

Lightroom 4.1 (3, 4 or any version) causes computer to blue screen and crash

Recently bought the new Lightroom 4.1 in an attempt to fix this issue, which had been occuring off and on for some time. I have major difficulties with importing and/or rendering previews or editing Canon 5D Mark II and Canon 5D Mark III images using Lightroom. The computer abruptly blue screens, then reboots. The blue screen code is 124. I'll attach a record of minidumps (all caused by editing or importing images using LR4.)
Not sure if that can be viewed, but please ask so I can send you the dump file for inspection if necessary. It essentially shows the Bug Check Code as 0x00000124, caused by address ntoskrnl.exe+4b09bc.

I have an 850W PSU. Running Windows 7 Ultimate on a 150GB SSD.
I find this very frustrating because it's a PC that I built and that can do any complex task--anything from using PS CS4 with multiple layers, playing top-end games like Crysis 2 and Diablo 3 with graphics on full. Other than this RAW development issue, the computer is flawless and VERY fast. Anyone have any ideas, or see a hole in the system specs?
Cheers,

The video driver is up to date, and I would assume compliant with LR4.
My BIOS version is default, and I tried installing new BIOS updates but ran into troubles. The Asus motherboard uses ATI Catalyst to introduce new system updates, but it fries my PC (assuredly a conflict with my nVidia card) making the rig run even slower. In fact, using the ATI Catalyst disc (the one that came with my mobo) crashed once I had tried to install any motherboard utilities! I've gone through the BIOS configuration and turned off all of this mobo's overclocking features and set everything to default.
No overclocking going on whatsoever--not once, and never will.
Reseated the memory and tested the memory with no negative feedback.
The PSU is relatively new and of high quality. I replaced an old PSU because of exactly what you mentioned above. It's a Corsair GS800 (not 850W, 800W).
I'm at the point right now where I suspect the motherboard is failing me somehow. I only bought it because I was in a rush and would have normally opted fro a "non-overclocking-enthusiast's" board. Perhaps there's a way of updating BIOS without utilizing the disc (the ATI Catalyst, more to the point?)
The PC is new in a sense. I seem to recall a point where LR3 worked with fewer crashes. I built the thing April 2011. Just reinstalled Windows 7 and all the software again.
