Graphic issue but goes away if I keep the fans running

So I have a graphics problem where I end up with lines covering the screen and screwed up video, however I am now certain this is due to overheating however I am not able to get new thermal paste for a week or two because of shipping. I am asking you if there is a way to keep the fans running at maximum output as when I have booted up the mac from a firewire drive, the graphic issues go away, but as soon as the fans start to die down it comes back within seconds.
Thanks

The graphics issue may well not be lack of thermal paste, but a failing logic board. Have you run Apple Hardware Test or 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.

Try the standard trouble-shooting steps: Restart, Reset, Restore. If these don't solve the issue then you may have a hardware probem. If so, contact Apple Support.
Restart: Press On/Off button until the Slide to Power Off slider appears, select Slide to Power Off and, after the iPhone shuts down, then press the On/Off button until the Apple logo appears.
Reset: Press the Home and On/Off buttons at the same time and hold them until the Apple logo appears (about 10 seconds). Ignore the "Slide to power off"
Restore: Use iTunes on your computer to Restore your iPhone to as new.

Use File >> Save As
Choose a different file name so as not to overwrite the original and don't save any changes when closing the original.

TS1587 I tried everything, except for reinstalling the SO-DIMM memory modules. Still, my iMac will not wake up. Turning it on you can hear the fan run, but the display stays dark. Any ideas what to do? Thanks Maja

Mac doesn't boot
Can you hear the fans and hard drive and see the white boot screen? Flashing question mark? The circle just runs and nothing happens? Only black screen and nothing else? These can be very helpful to diagnose the source of the problem. [1]
Flashing question mark [2]: This is usually a sign of a failed hard drive. This indicates that boot up volume can not be found.
Black screen: This is usually a sign of a failed logic board. There is no single reason for this and this may be caused by failed GPU, screen, CPU or RAM.
Circle of death/no circle/blue screen: This is usually a sign of a hard drive failure. This may NOT be a dead hard drive, just broken permissions or something
Gray screen/Apple logo/spinning gear or globe/prohibitory sign/folder with flashing question mark [3]: This could be a sign of faulty hardware but more likely a software issue, i.e. broken permissions, failed software update, etc.
[edit]
What to do
First, hold down the option key (also known as the alt key) just after you've pressed the power button. This should show all the available options to boot from, so if you have Windows installed through Bootcamp or a disk in your SuperDrive, you should be able to see them along with your OS X drive/partition. Select the OS X partition with arrow keys and press enter. Startup key combinations
If that doesn't help continue doing the steps from below:
1. SMC reset [4]. Shut down and unplug all cables including power cord for at least 30 seconds and then plug in power cord and keyboard/mouse.
2. PRAM reset [5]. Hold down option, command, P and R while booting. Start it when you hear the sound and don't let go before it reboots.
3. Safe boot [6]. Hold down shift while booting to boot into safe mode. If this works, open Disk Utility from Utilities and repair your permissions and verify the disk
4. Hardware test [7]. Insert the install disk (disk 1 in Mac which shipped with OS X 10.5.4 or earlier, disk 2 if shipped with OS X 10.5.5 or newer) and hold down "D" before the grey boot screen opens. Follow on screen instructions
5. Boot from install disk. Boot from the disk that came with your Mac. Hold C while booting. Select Disk Utility from top bar and repair permissions and verify the disk. Reboot normally and see if it works now.
6. Boot from another Mac (Firewire target disk mode). Connect the machines with a Firewire cable. Power on your Mac and press T. Select the other Mac's hard drive. Download the current OS X combo update. Run the combo update installer and select the drive that won't boot as the destination.
7. "Repair" OS X. Boot from the install disk as in point 5. and reinstall OS X. This should NOT erase any data, just replaces the system files which may have caused your booting problem. Now install the latest combo update for OS X and repair permissions on your drive with Disk Utility.
7.1. Install OS X into an external hard drive and then boot from it [8] and try to copy your data from the hard drive before proceeding. If you have done a backup recently, you don't have to do this.
8. Restore OS X from Time Machine backup. Boot from the disk that came with your Mac and choose the Time Machine restore option. This step will lose any changes made since your last backup but the system and your data will be put back to exactly as it was on that date.
8.1 Reinstall OS X. Boot from the install disk as in point 5. and select Disk Utility again. Now erase the whole hard drive and install OS X again. If you had a Time Machine backup and step 7 worked you don't have to do this.

How to force the display to sleep, while keeping the computer running?

I'm running some compression and transcoding programs on my iMac G5 (iSight) that keeps the CPU at 100% for hours at a time. My Energy Saver prefernces is set to sleep the display after a few minutes, but never to sleep the computer or the hard disk.
Like I'd expect with such a high CPU load, my computer's screen does not go to sleep.
Is there a program or command line utility that I can run to force my screen to go to sleep, but keep the computer running?
iMac G5 17" (iSight) Mac OS X (10.4.5)

To put your display only to sleep;
Go to System Preferences, click on 'energy saver', check the 'Put the display to sleep when the computer is inactive for' box, and then set the time. Note; this just puts the display to sleep, not the whole computer. Your hard disk will keep running. I find this much more convienent than putting the computer in 'full sheep'. It wakes up much quicker without some of the hassle some computers display coming up from full sleep.

How to patch clustered SOA domain keeping the domain running?

Hi All,
We want to patch SOA 11.1.1.3.0 to SOA 11.1.1.6.0. The SOA 11.1.1.3.0 environment is a clustered environment( 2-node cluster). Also database schemas are present in RAC database.
I know the patching process but my concern is I have to patch production environment and we have to minimize the downtime. Can we patch a WebLogic + SOA domain keeping the environment running ?
Please suggest.
Regards,
Roshni Shankar

Hi Roshni,
Check this:
http://docs.oracle.com/cd/E16764_01/core.1111/e10106/busreq.htm
It says, During the rolling patching of a cluster, each server in the cluster is individually patched and restarted while the other servers in the cluster continue to host your application
Always keep a backup before applying a patchset to your environment.
Thanks,
Sharmela

My Powerbook will not power up, but I can hear the fan running...

Please help!! My Powerbook will not power up, but I can hear the fan running when I press the power button to attempt to power it up. I just received a new power adapter because it wasn't working properly and it was doing this before and then it worked for a week and now it will not power up at all. It just starts the fan but nothing else turns on. When I plug the adapter, with the battery still connected, it will look as if it is charging but then the light on the plug turns from green to orange then off and doesn't power up at all. If I take the battery out and plug in the adapter, the light stays on but it does not power up except for the fan noise. Does anyone have any suggestions? I also followed the two articles listed online in regards to resetting the power setting and the command + alt + P + R as well. Nothing works. Thanks in advance.....

Same here. If I start up with the power adapter attached, it starts up fine. If I try to start up from battery only, the fan comes on, the sleep light comes on but nothing else happens. I tried letting it sit that way for about 15 minutes and nothing changed. I tried attaching the power cord while in this mode and nothing changed. I tried the PMU reset a couple of times but nothing helps.
This computer is just over 1 year old and I have not had any problems with the power cord (3rd party), the battery, or any problem like this before. It started after a proper shutdown last night and attempt to start without the power cord this afternoon.
Any answers to this yet? I think I'll call on this and report any success to this discussion.

I suspect you didn't reset it right.
Turn off the machine, let it charge up and then try the SMC reset again.

I can't get the audio Playhead menu to appear so I can trim an audio segment in a secondary audio track. I see others are having Trimming Issues, but I can't even get the menu to appear.....

I need to trim off the front and back of audio segments (pulling from iTunes)
The instructions seems quite clear on how to do this, but the Playhead Control does not appear when selecting and item in the secondary audio track. It seems pretty basic, but how do I even get the Playhead to appear?
I'm in hurry to finish a slideshow for a wedding (why I bought it to begin with) - any help will be appreciated.

That's the for the secondary track. But how do I trim the primary audio song from itunes. I did find a work around.
select the song in itunes.
command + I to get the information screen.
Under one of the tabs there is a "start" and "end" timer. Trial and error will put allow you to start and stop at the time specifed.
I renamed it " trimmed" so I knew it was a timmed version...then I inserted it into aperture the normal way...
A pain, but it works...

Macbook pro fan making loud noises and going really fast. Now the fan doesn't work at all and my computer gets extremely hot almost instantly. Is there a way to fix it without having to pay a ton of money to have someone fix it for me?

I've had my Macbook pro for about 3 1/2 years now. It has worked great until recently. A few months ago I noticed that the fan would always run really fast when I was doing simple tasks. After a few weeks/months, the fan was still really fast but it also started to make these loud noises. Now, it only occasionally makes the loud noise if I move my computer after its been stationary for a while. The fan no longer works at all and my computer gets exceptionally hot almost instantly when I turn it on. Is there a way to fix this problem without having to pay a ton of money to have someone fix it for me?

RunTime to keep the Thread running until it is closed

I wish to open a PDF file in Acrobat Reader from a JMenuItem in swing application. Until the PDF file is open, I want that particular JMenuItem to be inactive (setEnabled(false)). Once the PDF file is closed, that JMenuItem will become active again (setEnabled(true)).
I will find the answer if I can keep the "cmd.exe" running until servletjsp.pdf is closed in the following class. Please advise!

class Runner2{
public static void main(String args[]){
Runtime r = Runtime.getRuntime();
try {
r.exec("cmd.exe /c start servletjsp.pdf");

How to keep the fan noise down?

I use my 2010 macbook pro to make music every day.
I spend a lot of time in a small room with it and the fans go crazy as soon as i do anything slightly cpu intensive.
The fans come on and are pretty loud, even with some ventilation under the laptop they go crazy.
Is there a solution to keeping them down and keeping the mac cool without being noisy?
Thanks
