Screen freezing or turning to black

My imac is freezing and/or the screen is turning to black while I'm on the internet or while I'm using lightroom, happens 2 or 3 times a day. Unplugging, plugging back in works. Any long-term solution? Thanks, B.

Ipad 4 screen freezes or turns blue

Continues to freeze screen or screen turns blue. Have to do hard reset to get back on. Tried restore but still doing this.

Try and force it into Recovery Mode
1. Disconnect the USB cable from the device, but leave the other end of the cable connected to your computer's USB port.
2. Turn off the device: Press and hold the Sleep/Wake button for a few seconds until the red slider appears, then slide the slider. Wait for the device to turn off.
3.While pressing and holding the Home button, reconnect the USB cable to the device. The device should turn on.
4. Continue holding the Home button until you see the "Connect to iTunes" screen. When this screen appears, release the Home button. iTunes should alert you that it has detected a device in recovery mode. Click OK, and then click Restore to restore the device.
Note: Data will be lost.

TIF thumbnails initially populate, but turn 80% black when I "Open With PS"

I'm scanning photographs with a relatively-new Epson 10000XL scanner. I save the scans as ~300MB TIFs, copy the entire folder, then crop the copies with Photoshop CS5 12.0.3 on a Win XP 2.2GHz Pentium Dual Core CPU with 3.25GB RAM. The crop goes fine and the the save seems to go fine. Filesize of all cropped files is consistent. A few days later, I notice the image is 80-90% black, with only the top strip OK. This happens to about 15% of the images I've scanned. The original scans are always OK, so I think I can rule out the scanner. The cropped image thumbnails look good in Bridge, but when I right click and "Open with PS", the thumbnail turns 80% black and an 80% black TIF shows up in Photoshop...baffling. Sometimes half the image is black, but usually it is mostly black. Always, it is the bottom area of the image that is black. I can rescan and recrop the image, but a 15% rescan rate at 6-7 min/scan is killing me. What the devil is causing this? Is this a hardware issue, and if so, is it a RAM deficiency? Defective RAM? Defective hard drive? Conflicting software? Whimpy graphics card? Something else?

Replies to Curt and Omke:
In original post you said you were running Win XP, so it that home computer and work is Win7?
Work PC = Win XP, Photoshop CS5, Dual-core processor and 4 GB RAM. Home PC = Win7, Photoshop 5.0, Quad-core processor and 4GB RAM. Both are 32-bit OS. I cropped and saved 20 of these TIFs on the home Win7 machine, and had no problems with black images at any time. I tested those same TIFs on a work machine that is identical to my Win XP work machine, and had lots of problems with them turning black. This suggests that the OS, video card and/or CPU are causing trouble on the work machine, not necessarily the RAM. It doens't seem to be a problem unique to my PC, but rather to all the PCs that are just like my PC (our organization buys in bulk, and we all have identical PC setups).
Most likely it is the RAM. With a 64 bit machine you are really handicapping yourself with 4 gigs. You also need a good deal of space on the scratch disk, so make sure you have ample free space.
I have 62GB out of 150GB free on C drive, but it’s fragmented. Will try defragmenting to see if that helps. I think, with my 32-bit Win XP, I am limited to 4GB, right? Does a 64-bit system have that much improvement over 32-bit?
Graphics card is the other likely suspect.
On the work PC that is causing me trouble, graphics card= ATI Radeon HD 3450.
In Bridge go to advanced preferneces and check "use software rendering". That will help if graphics card is underpowered.
That will help with what, exactly? Will that help avoid corrupted files? It seems like the problem lies in Photoshop, not necessarily with Bridge.
In photoshop go the edit/kpreferences/file handling and make sure Open GL is not checked.
It was checked. I unchecked it, but still had images turning black on me when I cropped and saved them.
Your files are still OK, they only show not good in Bridge? or are they all damaged?
~15% of cropped scan tifs open mostly black in PS and Windows Explorer, and open mostly black in Bridge full-screen preview also. The other 85% look OK in all programs. The 15% initially look OK as thumbnails in Bridge, but after ~30 min, or if I try to open them in PS or full-screen preview, they turn mostly black. It would appear to me that those 15% of cropped scan files are corrupt, and perhaps only look OK in Bridge initially because Bridge is accessing some embedded low-resolution preview, then later updating the preview using the actual image file, but I’m not sure on that last point.
You state to have PS 12.0.3 in, while I'm on a Mac I have 12.0.4 installed s the latest so first try a software update.
That’s a pretty involved process with our IT dept. I don’t have Admin privileges to do that, but I’ll raise the issue.
Also check your PS performance settings. If you have only 4 GB RAM installed and you did point PS to more then the default and having some other applications open you will become soon short of RAM. (Bridge pointed to that already)
This is a point of confusion for me. PC specs list 3.25GB RAM, but in PS prefs, “Available RAM: 1691MB, of which 71% (1201 MB) is allowed for PS use. I would think PS would at least recognize all the PC RAM as available, but this is also the general trend on my home PC where PS doesn't recognize all the RAm that Windows does...must be a distinction between total RAM and available RAM.
In Bridge Prefs the default setting for maximum file size to build HQ preview is 1GB. Could you check if this is also your case?
Yes, that is the case.
And I also agree with Curt that if you have multiple files open with that size your machine specs should be above average, and you should have at least 10 % free space on your HD.
I’m running at about 50% free HD space, though fragemented. I would like to make some sort of recommendation to IT about a system upgrade, and it seems like a better processor is a key factor, followed by the OS and graphics card. Without going to a 64-bit system, I believe I'm maxed out on RAM, but correct me if I'm wrong. Our organization prefers everyone to be on the same OS, which is why we're all still on WinXP.

Screen freezing grey - intermittent

Hi all,
My MacBook Pro has started to behave strangely with the screen freezing and turning a grey color for a period and time and then coming back to life. It used to be occasional but its happening more frequently now. It seems to come and go, and might last a few minutes or longer. A few times it lasted so long, that I had no choice but to switch off power and restart. Everything just freezes and it turns grey and sometimes get more and more saturated grey after 30-60 seconds. I can tell the CPU is still processing but I hear the normal sounds with applications running. I tried putting it to sleep and then wake it up, but the grey is still there.
Any ideas?
Paul

Sounds like a hardware problem with the screen or graphics card then, best give Apple a call.

Some movies from my ATV1 I can only hear the movie while screen turns all black. Later it will freeze if I try to fast forward. Any ideas?

Welcome to the Apple Community.
This might be a problem with the movies themselves, where are they from, are they your own movies that you have converted yourself.

BLACK SCREEN on start up with 3 beeps, FREEZES when power unplugged, IF IT BOOTS splash screen freezes, OVERHEATING REQUIRED TO BOOT - 0x7B, Event 41 kernel-power

Issue: One day I unplug the power, the screen freezes and I get frozen music sound. I shut down, start up, I get 3 beeps (1 short 2 long), which indicates a Video failure according to the Thinkpad Laptop beep code list.
How I solve the issue day-to-day: I turn the heat up - I disconnect the battery and hard drive and plug in the power then turn it on. I will wait until the underneath is searing hot with a blanket blocking the fan's flow of air, I mean way hot because any
cooler and it won't start. Plug stuff back in, Hard drive first, Battery second, turn off with power button hold, unplug power, replug power.
I turn it on, no beeps, it goes past the first Lenovo screen, then gives me a prompt because it "didn't shut down properly" and continue regular startup. What happens next is the Windows logo appears,
and just as the animated windows logo starts to move (you see 2 small colored dots on the screen), it freezes. I see this every time, I know naturally that it means that the laptop is still too hot to go past that point, so I shut it down and try again. After
about 5 - 10 tries it will go past the splash screen and into the login area, then it's all fine.
Sometimes when I unplug the power from the back by accident it will freeze. By accident I mean that the connector wiggles it's self out easily. This unplug freezing thing started happening about 1 week before the 3 beep black screen problem started rolling,
so I'm putting 2 together.
Errors:
I got a Blue Screen of Death the first time I started it up with the overheating ritual, but I never got it since. It was 0X7B.
I got another Blue Screen of Death about a week ago, but came as it was on already and I had been using it, and said something about disabling Cache or Shadowing in BIOS. I never got it since.

I came across a very sluggish performing control panel for Nvidia before and after this problem, and I tried installing a newer version, which I had to jump through a few hoops to do, like uninstalling first, not just updating. At first it said that the
driver wasnt for the system, which was wrong. I made it work somehow, but it was still sluggish. I rolled it back to an earlier driver, and now it works fine. No sluggish performance / slight freeze window thing going on.

this in the past, but it does not save the setting now, and I believe this option was selected before I started having problems, and settings did not disappear then.
What could this be. The small round BIOS battery? The video card like everyone presumes? (I.E. the entire motherboard replacement), Software? The wiggly power input area? (Not enough power getting in?), Firmware of some sort? The BIOS software being wrong?

I got a Blue Screen of Death the first time I started it up with the overheating ritual, but I never got it since. It was 0X7B. I ended up changing a setting in BIOS from AHCI to Compatibility Mode, and I passed everything without the BSOD again. I have always had it on AHCI.

I'd beg to differ on both accounts.
*61 series nVidia-based ThinkPads from late January through July of 2008 are a 50/50 shot, since the old chips were mixed with the new ones. Any machine built in August and later can be deemed "safe".
As for the forums (I don't do feebay) there are people who sell genuine, properly-tested planars. However, these do not come at bargain basement prices, and with a good reason if I may add.
Good luck.

Try a system reset. It's quick, easy and harmless...
Hold down the on/off switch and the Home button simultaneously until the screen blacks out or you see the Apple logo. Ignore the "Slide to power off" text if it appears. You will not lose any apps, data, music, movies, settings, etc.

Ipod touch 4 freezes in middle of video and turns it black but audio still continues to play, how to fix this and what possibly caused it?

If you just got it back and it isn't fixed or something else is wrong with it take it back and have them do the repair correctly.

My ipad 2 turnes to black screen with the apple icon in the middle, it just hanged and i have to restart it?! so why this is happening ?! is there is an error or something i can do to prevent doing this ?!

my new ipad 2 turnes to black screen with the apple icon in the middle while using it or if i just left it locked for a while, it just hanged and i have to restart it?! so why this is happening ?! is there is a productio error or something i can do to prevent doing this ?!
Appreciate responding as soon as possible.

No, it's definitely not normal. Your User's Guide recommends a series of troubleshooting steps to go through when your iPad is misbehaving: As you're already in effect doing the first of the main steps, a Restart of your iPad, and that's not curing it, move on to the next .. a Reset.
To do this, press and hold both the Home and the Sleep/Wake buttons for about 10-12 seconds, until the display blanks and the red Power Off slider appears. Continue holding the buttons until the slider disappears, replaced by the black screen and white Apple logo.
This shows your iPad is starting to reboot. Release the buttons and allow the process to continue until the Lock screen appears again, then slide the slider to complete the process.

Hit Ctrl+0 (That's a zero, by the way). I'm not sure if it will work, but hey, that's the first thing I would try.
