Freezing Up & Display Distortion

Hello,
My iMac G5 has been freezing up lately, often with a cross-hatched or zig zag pattern taking over the screen. It does not appear to be related to any specific application.
Can anyone tell me if this is a software problem or a hardware problem? I do not think it is a virus based problem. Are there any suggestions where I should start my troubleshooting?

Does this apply to you:

When receiving email, Thunderbird freezes and displays "Not Responding" in screen header. Adds popstate folder to account.

I'm running Thunderbird 31.6.0 on Windows 8.1 with BitDefender 2013.
PROBLEM:
When getting email, Thunderbird freezes and displays "Not Responding" in screen header.
When TB is closed then reopened, a popstate folder (popstate-1.dat) is added to account. A new popstate folder appears with each crash/freeze, and as long as they are not deleted, they pile up with unique numbers (popstate-1.dat, popstate-2.dat, etc.).
(see attached screenshot)
NOTE: I've included troubleshooting details below for all the fixes I tried, thinking it might be helpful to anyone who has a similar problem and is thinking about going down those paths. Ultimately, it seems that FIX ATTEMPT 5 is the winner.
==================================
FIX ATTEMPT 1:
Following the suggestion in this archived mozilla support post: https://support.mozilla.org/en-US/questions/1026288, I restarted Thunderbird in Safe Mode (Help > Restart with Add-Ons disabled...), checking the "Disable all add-ons" and "Reset toolbars and controls" and clicking "Make Changes and Restart" button.
In Add-Ons Manager, BitDefender Toolbar now appears to be disabled.
(see attached screenshot)
But the problem persists.
FIX ATTEMPT 2:
Following the suggestion in this archived mozilla support post: https://support.mozilla.org/en-US/questions/1016811, I clicked Help > Troubleshooting Information > Show Folder button. This opens a File Explorer window for 3I58b9dq.default (this is the "profile" folder) which contains panacea.dat and folderTree.json files.
I changed file names to panacea-changed.dat and folderTree-changed.json (rather than deleting them, in case I need to restore them), and I reopened Thunderbird.
This did not solve the problem -- and, furthermore, the profile folder seems to have automatically generated new panacea.dat and folderTree.json files to replace those for which I changed the filenames.
FIX ATTEMPT 3:
Following the suggestion in this mozilla support post: https://support.mozilla.org/en-US/questions/1044774, I restarted Windows 8.1 in safe mode with networking enabled (using these instructions: http://www.howtogeek.com/107511/how-to-boot-into-safe-mode-on-windows-8-the-easy-way/.)
TB does not crash when Windows runs in safe mode, but the aspect ratio of my display is distorted; everything's really big and stretched horizontally, and my two displays are mirrored rather than extended. Running Windows perpetually in safe mode is not the ideal fix.
QUESTION 1: I understand that troubleshooting is supposedly done best in safe mode — What might I do in safe mode to diagnose the Thunderbird problem?
FIX ATTEMPT 4:
This article https://wiki.mozilla.org/Thunderbird:Testing:Antivirus_Related_Performance_Issues#Symptoms, suggests that problems with Thunderbird associated with BitDefender can be solved by uninstalling and re-installing BitDefender.
Not really comfortable uninstalling and re-installing, I disabled Bitdefender (Settings button > Antivirus button > Shield tab > On-Access Scanning toggle Off) to see if that would work. It did not fix the problem.
QUESTION 2: Would uninstalling BitDefender be any different than disabling it?
FIX ATTEMPT 5:
Create a Bitdefender Exclusion for the Thunderbird folder:
Settings button > Antivirus button > Exclusions tab > Excluded files and folders link > Add button > navigate to Thunderbird folder (c:\users\username\appdata\roaming\thunderbird) > Both radio button > Add button > OK button
THIS FIX DID THE TRICK! YAY!

FIX ATTEMPT #5 above did the trick, and now I see that it was the chosen solution for a similar post of the same problem at https://support.mozilla.org/en-US/questions/1044774

How should I find out the stuff that keeps freezing the display?

Hi,
I am using gnome-shell from testing repo on a laptop computer. The system(I do not know which part) has frozen several times in a same way. The whole display just suddenly stops reacting while I am scrolling down the web page in Chrome, opening a wine program, or something else. I have not figured out any pattern of its occurrence, so it's not repeatable for now. It seems that it's related to some modules or libraries used by Google Chrome browser or Wine because it mostly happens when I am interacting with Chrome browser.
It seems that only the display is frozen. I could not enter the tty with Ctrl + Alt + <F1...F8>, but I could move the cursor with my TrackPoint mouse. The NumLk/CapsLk LED also reacts normally. Even the network is working - when turning off and on the hardware switch of wireless, WiFi LED shows like the system is trying to reconnect the WiFi automatically.
If there's anything related Chrome, I guess one of the possible reasons is that when installing google-chrome-dev from AUR, I replaced libpci with libpciaccess in the depends array so that it won't cause a file exists conflict when installing.
Another possible reason is xinput, which I use for TrackPoint scrolling.
Now I am very curious in finding out what exactly it is that keeps freezing the display, but I'm not sure where to start. Could anyone give me some suggestions?
THANKS

thanks, but my SysRq and PrtSc are on same button, and when I press Fn + Alt + [PrtSc, SysRq], the system just recognizes as Alt + PrtSc. This is weird....

Bridge Freezing, Not Displaying Thumbnails, Says Disk Space is Low and to Purge Cache

Hello,
I'm working in Bridge CS5 on a Mac 0S X version 10.9.2. I have 12 GB of RAM and the server has 240 TB capacity, 76.69 available.
Recently I've received the following error message while processing large photo shoots with both DNG and JPEG files: Bridge is running low on memory. It is recommended that Bridge is restarted.
I have also been manually caching large photo shoots and my cache preferences were set to Keep 100% Preview In Cache and Automatically Export Cache To Folder When Possible. My cache size was set to 500,000. Yesterday, Bridge started to freeze while attempting to open folders. The wheel would spin at the bottom with the message Compiling Criteria. The only way to close Bridge was a Force Quit. This happened several times.
Today, image thumbnails will no longer display, only the DNG/JPEG icons. I received the following error message:
I have tried restarting Bridge while holding the alt/Option key to reset the preferences and checking all three boxes - no luck. I have done the same thing with the boxes unchecked - no luck. I have tried manually purging the cache from its location in the library - no luck. I have tried resetting the cache preferences from the toolbar - no luck. I have tried deleting the cache files from the folders - nothing changes. I have tried purging the cache for each folder from the tool bar - nothing happens.
I need to restore the thumbnails and rebuild the cache for each folder. Does anybody have an idea what is wrong or how to help?
Many Thanks!

Okay, so I have a solution. If after purging the central cache on the server Bridge continues to not perform normally try emptying the trash. I did this and it worked.

Mac Pro (early 2008) freezing after displaying a pink checkered pattern.

I upgraged to lion and a whole lot of issues arose.
The first thing I noticed is that I would keep getting an error message on startup saying that one of my computer USB ports is pretty much being overused in wattage. I also remember that it was getting a lot more warmer then usual and the fan was also sounding like it was overworking. This eventually lead up to the worst error - My computer would freeze up at random moments. Could be 5 minutes, could be upwards of two hours. It would eventually just display a very faint pink checkered pattern along across the screen. Once that happened, the mouse cursor on the screen would lockup, and everything would freeze until restart.
After a couple weeks of trying everything imaginable, I just reinstalled Leopard.
Everything worked flawlessly again. No power interupt messages, or lockups...
Until today (roughly 2 months after dropping back to OS Leopard). I was recording in Logic Pro 9 when I noticed a faint checkered pattern... I thought to myself, oh God NOT NOW! haha. But yeah, here we go again
I love this machine, and feel kind of cheated after only getting 3 years and 6 months use.
This machine has been well taken care of, and taken apart and put back together with care.
Any suggestions? The closest Apple Store to me is 3,000 km away.
I've heard stories of some of these machines having video card issues, hopefully that's just the case?
Cheers,
MistahTuck

Actually what graphic card was left out.
What you tried.
SMC Reset and AHT at top of my list along with of course a clean install
you researched your apps hardware drivers on Roaring Apps now that there is no Rosetta in Lion
What about a 'diagram' of your devices; your USB and how/where, any hubs. Maybe you need PCIe USB (USB2 or 3) controller.
Hopefully not using just 6GB RAM ("6" doesn't make sense otherwise though)

KE5Z - Actual Line Item report freezes before displaying the result

Hi,
We have a situation. We have a Z report in Finance. We have linked KE5Z to this Z report using the Report Painter along with 15 others. When we run the Z report it works fine and displays result. In the displayed result, if we futher drill down for the actual line items for a particular profit center, system freezes. It does not display any result even after a long wait.
We did our analysis and found that the program takes the profit center number range from the least available in the profit center group to highest available in the profit center group and starts checking for every line item in it. This happens when the profit center group has more than 50 profit centers in them. When we run KE5Z tcode individually, it runs fine.
We are not sure how to go about finding a way out of it.
Has anyone faced such issue? Do you know of any OSS note that can help us? or If anyone of you can think of a solution or a way to go about it?
Your help on this is much appriciated.
Regards,
Mukund S

Hi,
Any pointers to this will be appriciated...

Dynadock U3.0 freezes the display when connected

I am using the dynadock u3.0 docking station. The display/laptop freezes every so often. It happens most often when I visit a website with flash video (CNN/Youtube) etc. I thought this has to do with Chrome/Flash so I uninstalled/reinstalled etc but the issue still exists. The laptop when not connected with the docking station, it behaves fine. I am able to visit youtube, cnn etc. So I think the issue is with the docking station. Any idea how to get this fixed?

Try downloading the latest drivers from DisplayLink: http://www.displaylink.com/support/downloads.php

After ver 26 was installed my screen display distorts when scrolling - I tried resetting - no luck - any suggestions?

when I use either the scroll down bar on the right side or arrows up/down the display on the screen distorts at an angle as it moves up or down. does not reset with time

I think I saw a screen shot of this in a different thread, but I can't find it at the moment.
When there are strange display artifacts, I suspect a graphics driver incompatibility.
As a workaround, you could disable hardware acceleration of graphics in Firefox and in Flash (if relevant):
(A) In Firefox, un-check the box here and restart:
orange Firefox button (or Tools menu) > Options > Advanced > General > "Use hardware acceleration when available"
(B) In Flash, see this support article from Adobe: http://helpx.adobe.com/flash-player/kb/video-playback-issues.html#main_Solve_video_playback_issues
Any improvement?

Desktop Display distorted ... cannot see GUI to reset ... login window FINE

Please help ... Somehow (I did it but don't know how) the Display settings on my Tiger Mac have gotten to some setting that distorts the image beyond visual comprehension (diagonal scanline-like distortion). The login window is just fine, but when the desktop launches it goes batty.
I've zapped the PRAM to no avail.
I'm totally stuck.

First do this...
"Try Disk Utility
1. Insert the Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
3. Click the First Aid tab.
4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk."

Next do this...
Archive and Install feature...
http://docs.info.apple.com/article.html?artnum=107120
Then after booting up, repair Permissions, then reapply the combo update...

Calendar malfunction - calendar keeps freezing and displaying text I copied for another purpose - any advice?

My 6-month old macbook air's calendar keeps freezing up. when I open calendar, it displays across the top of the calendar some text I copied for another purpose and which I pasted into a word document yesterday. When this happens there's nothing I can do to escape it -- all commands result in the "thud" tone. So I keep having to force quit calendar.
Any advice?

Hi Dylan2412,
According to your description, you'd like to pass the ComboBox.Text to the second form's TextBox.
In Form1:
private void button1_Click(object sender, EventArgs e)
Form2 f2 = new Form2(this.comboBox1.Text); //pass the comboBox1.Text
f2.Show();
In Form2:
public Form2(string s) //get the string;
InitializeComponent();
this.textBox1.Text = s;
You could get the comBoBox refer to this sample above.
If you have any other concern regarding this issue, please feel free to let me know.
Best regards,
Youjun Tang

Macbook Pro Freezes with Screen Distortion and other problems...

So I've had my 13' Macbook Pro for about 9 months and I am encountering problems with it. My Macbook would sometimes freeze at random and the screen would distort as well, also, the screen would react whenever I would move the laptop around by either reverting back to a normal screen (still frozen) or more distortion which leads me to believe that it might have something to do with the hardware. But all this is temporarily solved when I force shut off my laptop (hold the power button for 3 seconds) and restart it. It can start up again with no problem, but this happens again, more early than usual and becomes more consatnt. However this is lessened whenever I don't use my laptop for an extended amount of time, but it does happens again whenever I do use it for some time.
Another problem I've been encountering is that, at times after I force shut off the laptop, my computer would not turn back on. Instead, the laptop beeps 3 times, pause, then beep 3 times again. I have looked into this and discovered that this means that I have "No Good Banks"..........I have no idea what this means but I guess it means that I might have faulty RAM.
What I ask is that if anyone has had similar problems and if they know what to do or what exactly what the problem is so that I might be able to do something about it.
Info about Macbook:
Processor 2.5 GHz Intel Core i5
Memory: 4GB 1600 Mhz DDR3

Bump. Anyone have any ideas on this?
I "shut it off" last night, but when I turned it on again tomorrow, it turned out it didn't quite shut down?
It booted to the grey log-in screen, basically.
I've also come to the realisation that my charger isn't registered (the LED isn't orange/green like it usually is), and I can't get a "battery status" (I'm sure it has another name, I just don't know what it is) when I click on the little button on the left hand side of the laptop. Usually, it would show green dots/LEDS to tell me how far along it's charged, but now I get nothing.
I get the distinct feeling something's up with my battery, and maybe my RAM (because of the repeated triple beep after shutting down last night).

How to freeze iPod display (intentionally)

Is there a way to freeze the iPod display so that it becomes immune to turning and touches?
The point: I have got something on the display which I want to show to someone else. Then I hand the iPod to the other person. At that point usually the orientation changes (landscape <-> portrait) or I or the other person accidentally touches the display and the content of the display is messed.
In iPad there is button which locks the orientation. But I want also lock the display so that it does not react on touches.

Not that I can find.

Iphoto displays distorted bright colors after calibrating display

Hi this issue has been occurring for the longest time. Sometimes when I calibrate my display or switch color profiles in system preferences and scroll up or down in Iphoto either (Events or Albums) A very bright distorted white and pinkish color will show throughout Iphoto covering all my photo's. The color intensity will change when I scroll up or down. This never happens unless I change the color profile in system preferences. Afterwards I will notice this in Iphoto. Is this a glitch? has anyone else experienced this issue? should I be concerned? Thanks

Thanks for the response. It doesn't just cover the thumbnails but all of Iphoto.
Scrolling up or down causes it to appear and change colors (either darker or lighter.) Once the distortion appears it doesnt matter if I scroll or not, it remains covering all of Iphoto.
This only happens after I change color profiles in system preferences.I haven't noticed this issue in atleast a month. Restarting the computer will fix this in Iphoto.
The colors that appear are red, pink, white or a combination. I rarely change color profiles or calibrate my display so it's a non issue for me but I was wondering if this was some sort of glitch or if other people have had the same issue as me.
Could there be something wrong with my Mac Pro? Next time it happens I'll take a screenshot of it.

Nokia 5230 display distorted!

After updating to the Nokia 5230 latest firmware version (V21.0.004), whenever the mobile receives a new SMS or call the display is showing up distorted (Snapshot included as attachment, take a look!). This is happening randomly may be every 4 out of 10 occasions. Not just when receiving the call or SMS but also when i activate the touchscreen by touchin it for performing any task. I have to either lock & unlock the touch pad to regain the display or wait till the mobile goes into standby after light time-out.
Is there any option for me to revert back to the recent old firmware version (V20.0.005)?
How to get rid of this? I already tried reinstalling the latest firmware again twice but to no avail. This is the first time such an issue surfaced in my mobile usage.
I appreciate your response.
Thanks!

Hi, unfortunately it is not possible to roll back to earlier fw.
If you've tried to reinstall the fw, there isn't much more to do other than take it to a Nokia care point as this seems to be a fault only they can repair.
I've seen quite a few posts on this matter, and some of the users reporting such faults happened after changing their displays themselvs voiding their warranty, earlier (before updating). I'm not saying that is what you've done, but just to let you know.
The " funny" thing is that this thing seems to happen often while updating, so it could of course be software related.
If youre up to it, you could perform a soft reset to clear your phonememory and start out fresh, but it's unlikely that this will helps. If you choose to do so, you will have to back up whatever you need from your phone memory as this manouver wipes contacts, messages, apps installed on the phone memory etc.
If not, you will have to see a nokia care point, and you probably have to do it anyway!

Why do I have screen display distortion that look something like barcodes when my browser is open and I start using another application such as word or excel?

Seems that whenever I am connected to mozilla and my browser (yahoo) is active, I will open games, word or excel, one at a time or open more than one at a time, I get screen distortions that look like bar codes that make it impossible to read or distinguish the images on the screen. It happens very frequently. I have tried changing my screen settings and updating my graphics card software. Nothing seems to help. If mozilla is closed and I am not browsing, I do not have this problem.

Thank you for your suggestion. I tried your suggestions and for a moment it appeared to work. I opened multiple applications, several games and a word document all at the same time. While I opened the games, it appeared to be fixed, but when I opened the word document the distortion appeared. I checked for graphics display drivers but there are none.
Thank you again. I would appreciate hearing from you if you have any other ideas.
