Preview launch but doesn't display anything
Well, everything was running (nearly), but since this morning when I want to view an image or a pdf, preview opens but does not show me the pdf or picture.
Iv' tried opening preview and than do file-open file, but I just got the same result.
any clues.
PS: the "nearly" is about an unresolved issue where very frequenly the macbook pro want shut down properly. It looks like it off, but it's not and it won't "wake". The only way I've found to get out of this "nearly off" state is to manually shut it down by pressing the power button for a few sec. Than it boot, but display a message saying that mac os didn't close properly...
Log back into your problem account:
Here's the whole litany for thoroughly checking your home folder. It's not as daunting as it looks.
1. Navigate to ~(YourHome/Library/Fonts - drag this folder to the desktop.
• Restart and test your applications.
• If they work start adding the fonts back few at a time.
( Likely suspects are Times RO, Helvetica Fractions and Times Phonetic, also if you do not use Classic you can trash the classic fonts.) If not, replace your Fonts folder.
2. Check Preferences Thoroughly;
• Navigate to ~(YourHome/Library/Preferences drag this folder to the desktop.
• Restart and test your applications.
• If this works, save the old preferences folder somewhere else or on disk, name it "old prefs" .
** Note: A very important file is the "com.apple.Mail.plist" preference file located in the Preferences folder which contains all email account settings and general mail preferences (hold this one and replace if your problem is not with Mail).
You'll have to go through some of your System Preferences and apps to set the preferences back to how you like them. (Or if you have the time and inclination, "cherry pick" through until you find the problem one or two.)
3. Check Permissions Inside Home Folder
• Navigate to YourHome/Library.
• Get Info (Command - i) on folders for apps you are having problems with.
• Open the "Ownership & permissions" disclosure triangle.
• Make sure you are the owner, with "read and write" access.
• Click on "apply to all"
• If this is correct, open the "Applications Support" folder and do the same procedure (Command+I) for the folders with the names of the applications you are having trouble with.
(Note:The reason to check this is because repairing permissions with Disk Utility doesn't touch permissions inside your home folder.)
4. Navigate to YourHome/Library/Caches and drag this folder to the trash, then log out and back or restart. There is no need to replace this folder.

MSI 970a-g46 motherboard starts up but doesn't display anything.
Hello, I'm having problems with a new motherboard I got from Amazon, specifically the 970a-g46. The following are my specs in use with this motherboard:
CPU: AMD Phenom 2 x4 965
GPU: nVidia GeForce 560 GTX
Ram: 8gb Kingston HyperX Fury 1866mhz.
PSU: Corsair 650TX (650 Watts)
Compatability-wise, everything checks out so I wasn't expecting problems at first. All the other parts excluding the ram I've used before. Here's exactly what happens:
I power up the computer after everything is installed and connected. The 4 phase LEDs turn on which tell me the CPU is powered up and working (so I assume). I don't get any beeps or buzzs mainly because I don't see any speaker/buzzer on this board. The monitor blinks and while it is connected to my GPU, it doesn't display anything, it's just a black screen. I can leave it on for a few minutes and I'll still not see anything happen. An important observation here is that my keyboard which has LEDs will turn on after a short period of time in boot-up (with my older set-up that is). This does not happen ever regardless of how long I leave my computer on on this new mobo.
I've gone over and checked/tested numerous things:
* The PCI-E and ATX cables for the GPU, motherboard and CPU are all connected and secured (I've tried both 4-pin and 8-pin connections for the CPU, neither help).
* I've tried jumping the CMOS multiple times to no avail.
* I tested the ram on another computer and it worked just fine on that one.
* I've tested the motherboard without a GPU and it still does nothing (though I think that's because this motherboard doesnt have its own integrated GPU for some reason).
So far the only possible reasons why my computer is not working is because of my PSU (very unlikely as it's only a year old and it's a Corsair, which I've heard is very reliable in the long-run), GPU (It is quite a few years old but even without the GPU my computer still doesn't go past boot-up), CPU (possible due to its age and how many freaking time I've reseated it (probably around 8 times) so I wouldn't doubt it, but before I put it into this motherboard I did check its pins and they were all there and placed nice and smoothly into the socket.) and finally the motherboard (it's possible that this is just a defected motherboard and giving me a super hard time which would be a first in all the years I"ve spent computer building).
The best case scenario of course is me giving some kind of oversight to how I transferred over the parts and connectors. I might've missed something obvious to please any advice/insight on how I can solve this problem would be greatly appreciated
EDIT: Some other things I did but forgot to mention:
* Checked ground nut things and ensured they matched the specifications of the motherboard ATX; only 6 are under the board and each one is aligned up with the holes on the board as designed.
* Tried booting up without powering the CPU. Only one phase LED light came on, still the same problem (for an obvious reason this time now).
* Re-seated GPU multiple times, re-connected cables multiple times.
What I have NOT done is re-seat the CPU because I am almost out of acetone so I would need to get another supply of that which won't be until tomorrow. I also have not re-seated everything back on my older motherboard to check if it still works. Tomorrow I'll most likely do that and if I find that the old motherboard works flawlessly then that tells me that the new motherboard I got is either defected or there's some compatability issue I"m missed out on.
EDIT 2: Just found a speaker and plugged it into the motherboard. Booted it up and I got no beeps whatsoever. So this mobo is giving me no video activity (there is a signal it's just blank), and no beeps from the motherboard. I have no idea what that could mean at this point.
EDIT 3: I decided to test a few things with the new speaker I just got. First I removed ram and tried running, I got 3 beeps which I assume is the beep sequence of faulty/no ram. Removed the power to CPU and the GPU itself individually, gave no beeps this time.Quote from: rhradacut on 06-January-15, 16:49:14
What's the serial number of your MB? Needed to determine what BIOS may be on the MB. Exactly which version of the CPU is it? There were several different 965 CPUs and they required different BIOS versions, 1.2, 1.9,2.2 depending on which CPU you actually have.
Also another problem may be that native memory supported by your CPU is DDR3-1333, not 1866
None of the supported CPUs have integrated graphics, any MB graphics would be in the chipset, not CPU. Examples would be 785G, 880G
Thank you very much rhradacut! The problem was that the mobo for whatever reason was forcing 1866mhz on my CPU when it only supported up to 1600mhz. I had to install a spare ddr3 module to downclock it so that I could access the BIOS and manually set the DRAM timing to 1600mhz for it to work. That's a very strange problem that I figured would've been auto-resolved by the hardware, and would also be a big problem if I didn't have any spare DDR3 ram to work with.
Once again thanks for helping out on solving my problem. -
Code compiles, runs but doesn't display anything, not even Exceptions?
The title just about says it all, but I don't even get a window, why is this? If it's some exception then it's not displaying for me to diagnose. Some pointers in what might be wrong would be really appreciated here - I'm pretty new to Java 3D.

Satellite M30X-111 screen doesn't display anything but external monitor works
My laptop screen just doesn't display anything (look like when the computer is off) but when I connect the external monitor, then the desktop will be displayed on that monitor. I tried to recover the laptop using the recovery disk and it worked again, but today, it stopped working again.
I again have to plug in the external monitor, and after I tried to reboot, I keep pressing F8 but the start up mode doesn't come up, only the sound of when you keep pressing a button for too long beeps, however, the laptop monitor works again.
How do I fix this problem?Hi
According to your first posting I presume that LCD display on your notebook is defective. If you can not see BIOS settings or Toshiba welcome screen there must be some display problem.
Experiment with external display is to be sure that graphic card is not responsible for that. In your case it works with external display and graphic card can not be responsible.
Like I said try to enter bios settings and report if you can see Toshiba welcome screen. -

My Contacts program appears to open, but doesn't display on the screen (it appears to be sitting just above the top right hand corner). any suggestions on how to get it back?
Launch Contacts, then on the "Window" menu select "Zoom". That should maximise the window and give you access to the bottom-right corner where you can resize it, and the bar at the top which you can drag around.

My iPod syncs, but doesn't save ANYTHING on the iPod
Basically, my iPod syncs, but doesn't save ANYTHING on the iPod, its the first iPod I have used and it really annoys me... I have tried pretty much everything :@
Help?!Hello JellyPopJade,
And welcome to Apple Discussions!
How do you have your iPod configured to sync with your iTunes library? Automatically or do you manually manage its contents by dragging what you would like from your library to the iPod.
If you have it set to automatically sync all checked songs and videos, make sure each track you wish to sync to your iPod is checked within your iTunes library.
Under the Summary tab for your iPod, is there any space taken of by the "Other" category (orange)?

Thanks for your lengthy reminder dude, I have a similar Mac with yours. I suspect its a software fault because it happens after I upgraded to Lion, 10.7.2.

PaintComponent method doesn't display anything on JLabel?
I am trying to show a histogram for a image in jlabel, but its not working.
//hist : array containing histogram values
//wid: width of image
//ht: height of image
mylabel.add(new showData(hist,wid,ht));
The code that I am using to display histogram is:
class showData extends JLabel{
int w,h;
int hist[] = new int[256];
int max_hist=0;
public showData(int[] histValue,int w, int h) {
System.arraycopy(histValue, 0, hist, 0, 256);
this.w = w;
this.h = h;
for (int i = 0; i < 256; i++) {
if(hist>max_hist)
max_hist=hist[i];
@Override
protected void paintComponent(Graphics g)
super.paintComponent(g);
int x = (w - 256) / 2;
int lasty = h - h * hist[0] / max_hist;
for (int i=0; i<256; i++, x++) {
int y = h - h * hist[i] / max_hist;
g.setColor(new Color(i, i, i));
g.fillRect(x, y, 1, h);
g.setColor(Color.red);
g.drawLine(x-1,lasty,x,y);
lasty = y;
When debugged, I found that showData() method was getting invoked, but paintComponent() doesn't. Why is it so? The Jlabel 'mylabel' doesn't show anything?Check size and location of the JLabel. If size 0 the paintComponent() is not called. Try to set preferred size to the label.

Safari runs but won't display anything.
As the title says, all Safari windows seem to have gone somewhere! The app starts but there's nothing visible. Enter full screen and the page appears. Try anything else and nothing at all is displayed. The app seems to be running just fine, right clicking the Dock icon shows a list of open pages, clicking "Show all windows" greys out the Desktop but shows nothing at all. Clicking View and Window options has no effect. I've restarted, but no change. Very odd behaviour, never seen it before. Any solutions?
I tried switching that Resume feature off, shut all apps, restarted, but Safari is still refusing to display *anything* except in full screen mode.
(Resume was proving to be pretty irritating on other apps though, like TextEdit and Preview, so I'm glad to know the off switch is there!)
But this Safari issue is a real puzzle to me. The timing is awful, I need to start accessing my new university course website from today and literally the first time I try this issue appears. Not a complete disaster, I can still open in full screen, but I usually use half a dozen windows at once and being boxed into one is very awkward and not a good start. -
Screen doesn't display anything. GT70
Me as a few other I have seen on the forum is having the problem were the laptop simply refuses to use anything but the Intel HD 4000 video card. I tried several different maximum performance settings to no success. I went into my device manage and display manager to see if the computer even knows it has the GeForce GTX 670m video card. It acknowledges the video card and I thought. If i disable the Intel HD 4000 it has to use the GTX 670m right? WRONG. The screen went completely black and refuses to display anything. I have absolutely no idea what to do now and need your help. I have tried hooking it up to another monitor but still nothing.
I dont understand in the first place why it refuses to use the graphics card I have paid for. Without it it has the same performance as my 4 year old 800£ computer I upgraded from.Removing the HD4000 that is used for non 3d load display of course results in a black screen as the Nvidia is only meant for 3D load.
For the switching working make sure your notebook has SCM (for Win 8): http://www.msi.com/service/download/utility-19670.html and Nvidia VGA OC (for Turbo/Win8): http://www.msi.com/service/download/utility-19690.html or S-Bar (for Win 7): http://www.msi.com/service/download/utility-19324.html and Nvidia VGA OC (for Win 7): http://www.msi.com/service/download/utility-18804.html installed

Mini Bridge in CS5.5 opens but doesn't do anything
I am running CS5.5 on a MacBookPro. When I try to use Mini Bridge the little gray panel opens up but there is no "browse files" button, I can't open settings, I can't search, I can't do anything with it! Bridge works works just fine. I am including a screen shot of my MB window to show what I am seeing. I have tried everything I could think of including restarting Bridge and PS. Is there something else I need to try other than a complete reinstall of the App, which I will not do just to get MB to work.
Thanks for any and all suggestions.I'm back to this discussion because I have never solved the problem. Today I uninstalled and reinstalled PS. I trashed preferences, checked to make sure Switchboard was working (it is), and have decided that my mini bridge extension is broken. Any place I can go to download a fresh copy? The window is dead. Even the settings selection doesn't bring anything up.

Photoshop CS4 doesn't display anything
I recently bought an Nvidia GTX260 graphics card hoping it would boost performance also in Photoshop. After installing the latest driver directly from the Nvidia website, I still have this problem: when I open a project, there is no error but nothing is displayed in the drawing area (so no canvas and no layers). The application works fine if I turn off OpenGL drawing. However I was hoping to use this feature to improve performance.
I tried:
1. Reinstalling the driver. Also I tried switching the openGL drawing option off before reinstalling and then switching it on after installation.
2. Enabling and disabling each advanced option I have to see if a particular one causes the problem.
I also mention I reinstalled windows and all my software and still does not work.
I was using NVidia 7300 graphics card before and experienced no difficulties.
I'm running Windows Vista x64 on a intel q6600 platform with 4GB RAM.
If you know of any solution to this problem please help.Thanks dec9. I did as you suggested.
This is becoming really weird.
So here is what I did:
I download and install DriverSweeper (latest version). It (surprisingly) erases all the Nvidia dlls and files so when I reboot, I have to reinstall Nvidia drivers for my graphics card. I install them and reboot. I open Photoshop and switch on OpenGL drawing and (although I did not expect it) it worked. I could see the canvas with the drop-shadow effect. I also mention here that when I switched on the OpenGL drawing feature, my graphics card name was not displayed in that rectangle above Advanced Options (usually it says what graphics card Photoshop detected).
So far so good.
I then exit photshop and restart my computer again. I get the same problem. It does not display anything. I tried a couple of times (also enabling and disabling OpenGL) and still nothing.
What is also "funny" is that if I move the layers on the canvas, the changes are reflected in the thumbnail of the layer in the Layers dock. And while I drag the window containing the project, I can see my work on the canvas. It is when I complete the drag operation that the canvas dissapears again.
It's definitely a driver thing.
Thanks for your help. -
ADE launches but doesn't load book
Hi~
I have used ADE in the past successfully, the last time being about 4 months ago. I am doing the same steps as I have in the past, but this time nothing happens.
I have an acsm file, downloaded from the same source as usual. I double-click on it. ADE launches, but the book doesn't appear in the libary. There are no error messages.
I see the acsm file in the task folder.
The manifest.xml timestamp gets updated, but no messages. I deleted this file, and all the old epubs reloaded, but no new ones.
No new messages in the error log or import log.
I run Mac OSX 10.7.5
I have ADE 1.7.2.1131
Is there something that needs to be upgraded?
Thanks for any insights.Launch the Terminal app (/Applications/Utilities/), copy & paste in this one-line command, hit the return key, quit Terminal, and restart. The command resets the LaunchServices database.
