Flickering and hanging problem

from the moment i have installed mavericks in macbook pro retina my dock and screen have been flickering. everything has become so slow. and even if i minimise any app it hangs while getting minimised. anything i do hanging and flickering is there. why is it happening and what should i do ?

New fllickering problem that just started today. I have a Mac mini with an external Apple Cinema display. Frequent black-outs of the screen make use impossible. No flickering on a guest account -- only on my regular user account.

What programs would be best to run to test the flickering and temp problem?

My new i7 has not shown any effects yet, but then, I have not put it through any stress tests. I do not want to particularly download too much new stuff. I am trying to work with the new mac as it comes from the factory for about 1 or 2 weeks before I start downloading or transferring files and data.
Are there any programs that are factory installed already, that I can use to really test the iMac both from the standpoint of flickering and temperature?
Thanks

How can I stress the new machine to see if it will initiate flickering at the same time checking the temperature characteristics?
I had loaded and running about 25 programs, many of which were doing graphics or video. Certainly this was not a controlled and precise benchmark; I just wanted to make it as busy as I could for a while. No problem detected under the maximum I could manually stress the machine. Certainly things got hot and the fans were running faster but nothing serious.
Just monitor the temperature with iStat as the programs are running and run Activity Monitor to watch the workload/memory use. After that test, I was impressed with the ability of this thing to multi-task and the HDD / CPU / GPU / screen were flawless.

Hi Bevmatt,
Welcome to Lenovo Community!
I’m sorry to hear that your G505s Laptop is not turning ON when the Battery is plugged-In, I suggest you to perform the Flee-Power, below are the steps to perform the same:
Remove the battery and any other peripheral device connected to the computer.
Hold the power button for 10-15 seconds and then connect only the AC Adapter and try to turn ON the computer.
If the issue persists, I would strongly suggest you to contact our Technical Support for further Assistance to get the details of the nearest Authorized Service Center to get the issue analyzed.

App Crash and Hang Problem

My App is already on store. It is 'File Locker' named App. It is for Windows store 8.1 only.
Users are complaining that the App crashes and so they loose their files. They are not able to open/see the locked files anymore in the App. Some Can't even see the main page of the App after crash.
These are some failure names I got from App dashboard:
APPLICATION_HANG_ACTIVATION
CLR_EXCEPTION_System.IndexOutOfRangeException
CLR_EXCEPTION_SYSTEM.UNAUTHORIZEDACCESSEXCEPTION
Can anyone please tell me what should I do in order to fix these issues?
As in my PC, the App is running fine,without any problem.
And According to the reviews and rating, I found out that the App is working fine with some while others are getting hell of the issues.
Please give suggestions.

Hi Dev06,
Per my understanding, the windows dashboard may has a channel to get the crash dump. Try getting it and use tool to analyze this dump file. See how to analyzing crash reports in windows store app.

Photoshop Elements 12 - Dropdown Menu Problem -flickers and will not stay descended to allow choice

Photoshop Elements 12 - OS Windows 8
While PE12 Editor loads without a problem, whenever I try to select an action from the dropdown menus - File, Edit, Filters, etc - the dropdowns flicker and disappear before I can make a choice to New, Open, or Save or Save as... or before I can make any selection whatsoever. The is terribly frustrating as you may gather.
I am an experienced software user and a member of Creative Cloud. I have used earlier versions of PE, so I am familiar with setting up the program and using its interface.
What are possible solutions to this problem. Any suggestions would be appreciated.

I have been messing around for the entire day and finally fixed the problem. I also had issues with the dropdown choices flickering and disappearing within 2 sec before I could make my selection. I went under the view tab and clicked Snap To choices. I unchecked the layers and document bound choices and now the drop down menus work fine.

Bought an iPhone5 from Dubai a week ago and am having a constant problem with the touchscreen going haywire. It starts flickering and apps keep opening and closing. Did a hard reset, restore, numerous times, same issue. Anyone experiencing the same issue?

The local retailer Sharaf DG needs 10 days to check the issue, not helpful at all. I spent more money to buy it from the retailer instead of the online store, and when I called Apple support they said they couldn't help me as I bought the phone from the retailer and not online. I'm extremely disappointed as this is my first iOS device and I've been told about how the iPhone is bulletproof. Guess i got a lemon.

Ok Guys, got the device back. Service centre said they replaced the Display and touch panel. I would have preferred a new phone, but whatever. I just hope this does it and the problem is fixed. @Robo, I've also got a new nano-SIM from the carrier, so hopefully now anything that can cause the phone to go crazy, is fixed.
Will update everyone in a week to confirm that the issue is resolved. Many thanks for everyone's responses.

I have a 17" Macbook pro with flickering red and cyan(blue) lines across the screen. The issue disappears temporarily when I tap on the computer, and the problem does not occur when I use external display or try to screen capture the problem.

I purchased my Macbook (17") through a certified apple tecnition in August 2012, it was refurbished and the motherboard was completely replaced. I do a lot of photo editing, but I have been unable to do so because of the red vibrating lines that interrupt my screen. The issue disappears temporarily when I tap on the computer, and the problem does not occur when I use external display or try to screen capture the problem. I brought the computer back to the technition I purchased it from and he said that it was a problem with my fan, so I have two new fans but the issue is still occuring. He says he doesnt know whats wrong. Does anyone have any information on this issue?
Here is an image of the issue

I recommend having your Mac serviced by someone competent. A force sufficient to "blow apart" the fans was clearly excessive and may have damaged the display cable, as well as any number of other problems.
Dust is properly cleaned with a vacuum, preferably one designed for computer service, and they are not cheap.
Compressed air should never be used. It just blows dust everywhere, often into places where it can no longer be removed.

What's wrong with my MacBook? It's flickering and beeps.

I bought my MacBook Pro 13" in October 2012. It worked fine and then on December 25 I was using it and a rainbow on vertical stripes started flickering and took over the screen so I had to hold down the power button and shut it down. I took it to the Genius Bar and she did nothing for me. About a month ago the screen started to flicker and was completely distorted. I took it in and they sent it to Austin where they reset the RAM. I got it back and yesterday I pressed the power button and the screen stayed black and it beeped three times then paused, beeped three times, paused, and continued in this pattern. And later last night I tried to turn it on again and it turned on but after about five minutes it flickered and the screen was completely distorted. So I forced shut down. The same thing happened again this morning with it working for about 5 minutes then distorting. This is annoying because I've taken it in twice and it continuously have the same problem. The only thing I have downloaded is Google Chrome. Before they sent it in and reset the RAM and to factory version I had Sims 3 on it but when I got it back Sims 3 wasn't on it because I was reset to factory settings, so Sims couldn't be causing it.

My Mac is doing strange things: delaying between users, mouse flickering and bouncing, gets stuck with rainbow wheel flickering. I ran the appel hardware test and it detected an error: 4MOT/4/40000003:HDD-1233 Does anybody know what that means? HELP!

My imac is doing strange things:
-delaying between users: when closing session it goes to blue, then takes a while to appear users signin box, and then wont recognize mouse command to enter until a couple of minutes later... then everything seems alright until....
-it gets stuck between things, the rainbow wheel appears and its just delays there forever....
-and every now and then the mouse starts flickering and bouncing wildly onscreen.

Does anybody know what that means? HELP!

WZZZ answered about where to get iStat. And do check the SMART status. If it is an overheating problem due to a fan or logic board problem, your hard drive is possibly cooking itself to death. If so it isn't a faulty hard drive even though the hard drive might fail. So assuming it's a temperature problem, even if you are able to repair things on the disk with software, that is working on symptoms, not causes. I could be wrong however.
RE: AppleCare: Your iMac came with one year of AppleCare (Apple's warranty program), but within the first year you can buy 2 more years. You have to extend by the one year anniversary of purchase of the computer. Your 10,1 is too old to still be in the first year, and since you asked what it was, I'm sure you don't have it. Bottom line meaning is that whatever this problem turns out to be, you'll have to pay for it. Unless there is something like this. It is for 2011 iMacs with certain Seagate drives. You can put in your serial number for fun, but it looks like yours is too old. Lastly, some people have had Apple help them anyway if it is just out of warranty, but many have not. Your machine is one of these. Type in 10,1 in the search box. Is there an Apple Store near you? Just b/c it's out of warranty doesn't mean you shouldn't have it looked at by Apple. But no one here can say at all what Apple will or will not do.
Hope you get it taken care of!

MacBook Pro screen flickers and freezes after Snow Leopard/Safari 5 updates

Hi guys,
I have a silver 120GB 15-inch MacBook Pro from Summer 2007 with 3GB RAM and 25+GB free space which has recently begun to freeze irrecoverably. The first appearance of these symptoms seems to coincide with my installing the Snow Leopard 10.6.6 update via Software Update.
I'm not particularly well versed in computer technology, but will try to describe my problem as detailedly as possible.
What happens is this:
1. I start the computer as per usual, with only a couple of startup items. Everything's fine.
2. I start working. Use a lot of Safari 5 for browsing websites, often with some kind of Flash or "Flash-type" content such as banner ads, videos, even full Flash designs. I may also have programs such as QuickTime, VLC or an image editor open, if not necessarily "actively" doing anything. Everything's still fine - I'm able to both browse websites and watch videos as usual.
3. After a while of active working - say, 1-3 hours - I notice browsing websites gets a little choppy. Display features such as the file list view in Finder may or may not appear properly. The rotating wait cursor may or may not appear from time to time.
4. Immediately after symptom no. 3, the next time I start to watch a video, either via Safari 5 (say for example something on DailyMotion.com) or a file via QuickTime, something goes wrong.
Following no. 4, one of three things invariably happen:
5a) The video freezes and the entire screen flickers from black to the screen view very quickly two or three times, after which the computer or screen appears to freeze. The cursor still moves, but nothing reacts to it - open windows become completely unresponsive, nor does the top or any other menu react in any way to clicking. The "menu row" of application items, which normally appears when I move the cursor to the very bottom of the screen, doesn't appear. Restarting "blindly" by pressing the Off-button once and pressing R doesn't work. I'm forced to do a hard reboot, after which the computer is once again fine until the next two hours of active working. This usually happens ONLY when I try to watch a video in Full Screen-mode.
5b) I notice the video freezing only just in time, and am able to pause it and "esc" out of Full Screen-mode, and the computer remains operational. However, as soon as I again try to play video in Full Screen-mode, everything described in 5a. happens.
5c) The video stops playing, and the screen reverts momentarily to pale blue before switching to the login screen. I login again with my details, and everything appears to be fine again until the next two hours of active working. The computer "starts up" a lot faster than with a hard reboot. This usually happens ONLY when I've tried to watch a video in its original size, i.e. when not in Full Screen-mode.
This happens 1-4 times a day, and it appears to depend directly on how much work I've been doing on the computer. The less I use it in the course of a day, the longer it takes until the next time it freezes.
So, in a way, I'm able to replicate this problem. 95% of the time the screen has frozen while watching or starting to watch (usually already when starting to watch) video footage, but it has also frozen a couple of times just switching between e.g. Safari 5 and an image editor or browsing a website with a Flash banner ad or embedded video content (which however hasn't necessarily been playing); today, the screen froze when I tried to open a website made entirely with Flash.
Although it could be just a coincidence, I believe this issue first appeared when I updated Snow Leopard to 10.6.6 via Software Update alongside some other pending updates, including as far as I recall one for Safari 5. The update process appeared to have gone well at the time, though, and was not interrupted in any way. I have never had this specific problem with the computer/screen before, though.
I've read a couple of threads here regarding very similar issues with newer MBP models than mine, in which it has been suggested that the fault may lie in a malfunctioning NVIDIA GeForce graphics card. Now I've had that replaced already once because my screen went unexpectedly completely blank after a forced reboot 1-2 years ago (I don't remember exactly), but according to my System Profiler info the card still a GeForce 8600M GT. Can it be failing again?
I've also had some kind of a RAM card failure once. As far as I understood it, one of the RAM cards had fried and was preventing the computer from starting up. I replaced the bad 1GB card with a new 2GB one and the problem was resolved. Before the computer died, there were also other symptoms, but they were not similar to these.
I'm also doing the Apple Hardware Test tomorrow. Any other suggestions, though, than the graphics card?
*Could this have to do with Flash or Safari 5?* Just hear me out. Even though my computer has frozen from watching a video in just QuickTime, Safari 5 has always been open in the background at the same time, and more likely than not with websites with "Flash" content open. And come to think of it, before I performed the Snow Leopard and Safari 5 updates, I used to have daily problems viewing Flash video in Safari 5, the video content either suddenly showing up as "Plug-in Failure" or crashing the browser; I've had both Safari 5 and the Safari 5 Flash plug-in "quit unexpectedly" countless times in the past, almost daily. Sometimes the "Plug-in Failure" could be fixed just by refreshing the browser view; at other times, Safari 5 would stop showing Flash content altogether - Flash banner ads (such as Google ads), YouTube and other Flash videos, everything - until I quit and restarted Safari 5. BUT - since the day I updated everything via Software Update, I don't remember this happening; it never gets to "Plug-in Failure" now. Could it be worth trying to use e.g. just Firefox for a while or is there something (e.g. Adobe Flash) that I could try reinstall? Or am I just clutching at straws here?
Thanks for reading this long, long post!

Do you have access to an Apple Store? If so, it may be worth making an appointment at the genius bar and having them run the test for the NVIDIA problem. Since your replacement logic board still has the NVIDIA GeForce 8600 M GT video chip, it could be starting to happen to your replacement logic board.
I also agree with all of CMCSK's suggestions. Freezing is often associated with hard drive problems. You might also want to run SMART Utility:
http://www.apple.com/downloads/macosx/systemdiskutilities/smartutility.html
You can download the demo and run it several times for free. It will give you a very comprehensive view of the physical health of your hard drive. If you still have the original one from 2007, it's getting pretty long in the tooth and may be approaching the end of its average useful life of 3-5 years. I just recently had to replace my original 2007 Fujitsu drive.
If your drive is headed south, and is also too small, it may be time to upgrade to a larger and faster drive.
The software update probably didn't cause the problems, but it may have exposed problems that were already in existence.
Good luck!
