Imac unplugged affecting the mouse

The power chord disconnected by mistake from the imac when it was turned on, shutting the computer down. When I turned it back on, the mouse became a lot jumpier. It no longer works as well as it used to. When I move it to a spot, it doesn't go directly to the spot, like it did prior to the computer shutting down by mistake. I ran disk utility and repaired the disk. Doesn't seem to help. I have a very good mouse, the Razer Death Adder, connected by USB. Any suggestions to bring back the mouse to where it was prior to unplugging. Thanks!

HI Ric,
Try a different USB port for starters.
As for preferences, try this. /Users/YourName/Library/Preferences. Open the Preferences folder and look for a file similar to this. com.razerdeathadder.plist or something similar that. Drag that file to the Trash, empty the Trash and restart your iMac. Preference files can become corrupted. Your iMac will create a new pref file for you.
If that doesn't help. turn off the iMac. Disconnect the mouse. Wait about 5 minutes. Reconnect the mouse and press the iMac power button. See if that makes a difference.
Here's how to reset the PRAM/NVRAM. http://support.apple.com/kb/HT1543

HT3964 i think i have a virus on my imac that affects the keyboard. buttons are haywire. when i press 't' TUY comes up. when i press enter 0-;/ comes up

i had some browser viruses like mysearch and inbox that i think came from downloading sophos. using the onscreen keyboard right now

From the Safari menu bar, select
Safari ▹ Preferences... ▹ Extensions
Turn all extensions OFF and test. If the problem is resolved, turn extensions back ON and then disable them one or a few at a time until you find the culprit.

TS3092 I received my new imac and the mouse doesn't work

I just recieved it yet the magic mouse doesn't seem to work. Like it wasn't even paired in the the first place?? What's wrong?? And how am I going to use my imac

Hello:
When you first turn the iMac on (and the mouse, of course), the device should start to pair.

Ive updated too Lion on my iMac but usually my mouse pointer doesn't appear after I wake the computer so I have to do a hard reboot. Any suggestions?

I've updated to Lion 10.7.1. Now when I wake my iMac from sleep, the mouse doesnt appear so I have to do a hard reboot and than i shows up fine. P.S. I have a mouse & trackpad. Any help?

I've heard that resetting the PRAM may solve issues like mine.
It does not hurt to reset the PRAM, so give that a try.
Is the 24GB RAM all Apple RAM, or did you add 3rd Party RAM? If 3rd Party RAM, this could be the cause.
Do you have 3rd kernel extensions? 3rd Party software can cause problems, especially those that add kernel extensions. Posting the EtreCheck output would show all such extensions
<https://discussions.apple.com/docs/DOC-6174>
Did Apple have SSD/HDD combos in 2011? I really do not know, so I'm asking. If this SSD/HDD combo is a 3rd Party addition, then disk issues might be an issue. Then again, a failing disk (Apple's or 3rd Party) can ALWAYS be an issue.
Is your SSD/HDD configured in a Fusion Drive setup? Again, if this is not original Apple SSD/HDD Fusion Drive setup, is it possible your manual configuration is having issues?

Sorry to say but your imac g5 logic board has bad caps. This was a problem apple had and issued a out of warentee fix but that has now expired.
The cost to get this repaired is more than what you could find another used imac for.
I would suggest you get some details before you rush to make a diagnosis. You have absolutely no information to base this on. I see you're hitting up on numerous threads all over the place. Quality, meaning several good posts with reliable advice, is much more worthwhile than quantity.

My IMac shunts down or the mouse freezes seems to be after installing OS Lion

my IMac shuts down and I have to unplug it and turn on again or the mouse freezes and I have to restart the computer

I tried that solution, but it didn't help in my case. There is a workaround that usually works, though:
When the RMB stops working, use the "screen zoom" function (ctrl + mouse scroll ball) to zoom in to the screen a bit, then zoom out again. This usually makes the RMB start working again, at least for a while. If it doesn't help, then rebooting the computer usually does.
Still looking for a more permanent solution though.

I have an iMAC from about 2007. The mouse will not scroll down. Can this be fixed?

You have to remember, where the scroll ball is, there is a small gap which picks up dust and fluff. That detritus gets everywhere and in your case affects the downward scroll.
Adding just a touch Linc Davis's suggestion, after you have vigorously rubbed the scroll ball on the pad, tap it on a hard surface from time to time. Sometimes you will see small amounts of fluff appear. You should also see dirty marks on the pad.

My IMac won't turn on and it's plugged in and the batteries on the mouse and keyboard work. What's the problem then?

I have an IMac and I tried to get on it this morning, but it wouldn't start when I touched the mouse pad. I tried this a couple more times, and then I tried it with the keyboard. I got the same results. I know there are fresh batteries in there so I didn't see what the problem was, so I tried turning it on, and I got no reaction. My IMac is plugged in and everything so what's the problem?

Make sure the outlet is OK. could have tripped circuit breaker.
Then try resetting the SMC
Resetting the SMC for Mac Pro, Intel-based iMac, Intel-based Mac mini, or Intel-based Xserve
Shut down the computer.
Unplug the computer's power cord.
Wait fifteen seconds.
Attach the computer's power cord.
Wait five seconds, then press the power button to turn on the computer.
If it still fails to turn on you need to make a Genisu Bar appointment at an Apple Store or contact Apple Support.

What could be causing my iMac Intel to reboot when I touch the mouse???

This problem has existed for most of the time we've had our Intel iMac since June 2006 and it's been worse recently. We'll come to the computer which has the screen dimmed and touch the mouse to make the screen wake and it just restarts. It's like the "wake from sleep" and "restart" are somehow wired together. It doesn't happen everytime and I thought it might be from SuperDuper because the iMac is generally connected to a GTech 500GB drive for daily backups. But, after unplugging the drive it's still happening. I'm not sure if there is software that can help me diagnose this problem as I've dealt with it before. I've done all the usuals like repair permissions, repair disk, ensure I have all the latest versions of software, rebuild desktop with Disk Warrior, optimize and repair with TechToolsPro, yadda, yadda, yadda. None of these has made any measurable difference in this randomly annoying problem that is just getting on my nerves enough to post on the discussions
Anyone have any thoughts about how to proceed evaluating this further or could point me to some suggestions on how to fix this? Thanks much!

I thought more about your issue after my last reply and the only other thing that came to mind was the logic board or power supply problem.
Try running the Apple Hardware Test, it may or may not find an intermittent power problem.

Your best bet is to take the iMac in to your local Apple Service Provider or Apple Store and have them test it. If you purchased Apple Care with your iMac then all testing and repairs will be covered.

My Mac was accidentally unplugged from the back of the computer when I restarted it the mouse and keyboard lost all connection and I cannot bring it back what to do?

iMac was accidentally unplugged and I lost connection to the mouse and the keyboard and it will not reconnect. Need help.

Get any usb mouse connected and open the Bluetooth pane in system preferences to re pair your Bluetooth keyboard and mouse.
You may also need a usb keyboard if your system is password protected.

Just bought new iMac. When browsing in Safari, sometimes the text suddenly gets super large. I'm doing nothing except reading the screen, tho I have my hand on the mouse. I can get back to normal size by clicking "actual size" in View. What gives?

Just bought brand new new iMac. When browsing in Safari, sometimes the text suddenly gets super large. I'm doing nothing except reading the screen, tho I usually have my hand resting lightly on the mouse. I can get back to normal size by clicking "actual size" in View. But then it does it again a minute or two later. What gives? Something seems defective--but what?

From System Preferences, Mouse, Point & Click, Secondary click. Go to it hover over Secondary click and watch the short video sequence change it left right, left right, you will see exactly what is does. No I do not think your Mouse is defective, you simply need to take control of your Mouse finger.

Since I downloaded Maverick, I cannot find my External Hard Drive in the "Finder" area. I have to unplug all the time the hard drive to be recognized by my iMac. How can I fix this problem? Thank You.

Check Finderr->Preferences->General and ensure that HDs are selected for display. If so and they still don't, Reset the NVRAM/PRAM and Reset the SMC, and see if that does the trick.

Hello USME,
'Tis a common problem on old Macs.
Do as Allan says: open the door and blow out all the dust bunnies. Canned air from Wal-Mart or Radio Shack can be handy (though sort of expensive) especially for blowing through the back of the power supply. A cool Mac is a happy Mac.
Be sure your Mac can breathe. The air intake is on the bottom of the case, so be sure a deep pile rug or too many papers on your desk are not blocking the air supply.
Feel the power supply and the processor with your hand. They should be warm but not hot; if you have to move your hand away, that's too hot!
Check the fan on the power supply, and on the processor if it has one. Take a flashlight and peer in the back of the (Mac) case through the grille; make sure the fan is turning. If it's not, the power supply won't work for long.
Fans are not considered serviceable, though they will succumb to mechanics of determination. A CPU fan is easy and straightforward.
A fan replacement will not cure an already damaged power supply; the PS may already be done for. Used power supplies for a DA are hard to come by, and not especially cheap when found (c.$50). An entire working DA or Quicksilver may often be found for under $100 on eBay, and swapping in your HD is easy and simple... this might be cheaper and more expeditious than repairing an expired DA. Replacing a power supply is fairly easy, but it's a nuisance and requires a 2mm Allen head wrench in addition to the usual #2 Phillips head screwdriver.
In my experience, power supplies and CPUs are about equally likely to fail. There are a few other possibilities, but they are not nearly so common.
Good luck!... Jon

2007 intel based iMac has the white screen of death with the mouse visible?? WHATSUP

My 2007 Intel based IMAC has the white screen of death with the mouse cursor as the only visible item. What is up with this? Is this the equivalent of the windows blue screen of death?

The mouse that came with my imac does not work very well in a window virtual machine

I finally got Windows 7 on my iMac and am using FusionVM. I installed one of my favorite games and the mouse goes soooooo slow I cannot use the game. Any suggestions? I am using the mouse that came with the iMac, magic mouse(??).

I have already tried that. The mouse speed on the iMac is good. The mouse speed in other Windows7 programs is good. The problem arose when I tried to play Zuma's Revenge using Windows7. This is the first game I have loaded since setting up the virtual machine.
