Very Slow Performance After Removing Windows Partition

Hello,
Recently I went through a failed attempt at installing Windows 7 onto my Macbook Pro using boot camp. After this failure I decided to try again another day and used the boot camp assistant to remove the Windows partition.
Ever since doing this, my computer has been running extremely slowly and beach balls on the simplest of tasks. I have tried resetting the SMC and my PRAM all to no avail. I have also used Disk Utility to verify my disk and it says that my disk looks OK.
Has anyone else experienced this/know of any possible fixes?
Thank you for your help!

Hi,
This may happen sometimes due to anti-virus or firewalls also.Disable them and check if it works better...Or, otherwise try these:
- First uninstall the latest Windows Updates.
Click on the Start Button> Type Windows Updates in the Start Search box > Click View Installed Updates at appears at the top > In the Installed Updates screen Sort the updates as per installed date by clicking on the Down arrow next to installed and choose a date or last week...
Uninstall the updates that were installed recently one by one. Do not restart.Click cancel on restart window.
Then perform a clean boot as shown in the link and follow these steps:
Perform a clean boot >
In the start search box type msconfig > Click Startup tab > Click disable all at the bottom > Then Click services > check the box next to Hide all microsoft services at the bottom > Then select disable all > Click Apply > Ok and restart.
Once it restarts then go to windows updates and complete all the updates > Restart and check. If it works better then Go bak to msconfig and enable only the startup programs and services that are required. Enable few and check again..
Let me know if problem continues..
Note:
If you have HP Support Assistant installed on the computer(The Blue Question Mark) then open it ==> Complete all pending Updates & Tuneups==> Restart and Check. It may solve your problem
Although I am an HP employee, I am speaking for myself and not for HP.

Very Slow Performance After Failed Bootcamp Install

AKsunshine,
if you boot your MacBook Pro into Safe mode, does it still run extremely slowly when performing the simplest of tasks then?

Why can't I recover disc space after removing Windows partition?

Greetings,
I have an early 2008 iMac 3.06 GHz Core 2 Duo with a 500 GB HD that I have steadily updated from Leopard to Mountain Lion. I also had partitioned my HD using Bootcamp 2.0 to run Windows Vista Ultimate 64-bit. Everything hummed along nicely until the upgrade to OS 10.8.2. After that I could no longer start up in the Windows partition, ostensibly due to system registry files having become corrupt (or missing). After several vain attempts at recovering Vista, I determined to start over using Bootcamp (now upgraded to 5.0), but 5.0 would install Windows 7, apparently not Vista. I was able to remove the Windows partition using Bootcamp 5.0 (the Windows drive no longer shows up at start up when I hold down the option key Macintosh HD and Recovery 10.8.2 remain). I was hoping to recover the remaining HD space for the Mac. In Disc Utliity, it shows the Mac HD occupies 337 GB of space (about 86 GB is free). The remaining 162 GB is greyed out. If I resize the Mac HD to take up the remaining space and attempt to repartition it says "Partition Failed -- couldn't modify partition map because file system verification failed".
I would like to recoup as much of the 162 GB as feasible, but at this point neither Bootcamp nor Disc Utility seem to be helping. How can I accomplish this?Thanks.

I have a problem on my early 2011 macbook pro customized with core i5 processor and 500gb hdd regarding BOOTCAMP for Installing Windows 8 on OS 10.9 Mavericks
I tried to install windows 8 with bootcamp on OS X 10.9 Mavericks but while partitioning bootcamp was not responding and then i force quit it. After that i opened disk Utility and it showed no partitions for windows 8.
But then my HDD which had 210GB free later showed as 136.27 Gb free only. IT means that my partition was not successful and it took up 74GB on my HDD.
I dont want to erase my HDD and Reinstall OS X but want a solution to get my 74GB space back on my hdd without troubles of formatting and restoring from backup.

Clicking noise to the right of mouse pad, and very slow performance after updating software to Yosemite. Does anyone know what the issue might be?

So I recently updated to the latest Yosemite software (last night to be exact), and this morning i started to get a weird clicking and sort of grinding noise to the right of the mouse pad and extremely slow performance. I have no idea what is going on. If anyone has any ideas or suggestions please let me know.
Thank you

VERY Slow performance after upgrading to v4.5

Since I upgraded to to v 4.5.138 my VZ BB 8830 has slowed to a crawl. Even trying to make or receive a phone call I get a spinning hour glass for several seconds. It gets worse over time to the point where I have to take the battery out and restart.
Then it is OK for a few minutes but gets progressively slower. Very annoying.
Also, I can no longer sync, either with PocketMac or with the new BB DTM, despite uninstalling everything and reinstalling.

Holding the power button turns the phone off.....
alt, shift, del resets the phone.
When turning the phone off, the phone is in a low power state I believe....I don't think it actually turns completely off. As you can set it to come on at certain times.
A reset is the proper way to go.
It actually mimicks removing the battery.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

Very slow Safari after IOS8 Iphone 5S

Hello all
I live in Iraq, so basically internet here is very slow, however after installing IOS 8, Safari now is very very slow
I tried other browsers and they were a better
any one of you guys have similar issue ?

My iPad and iMac are really screaming after the update. My iPhone 4 is running more slowly. What's odd is that even with it right next to the AEBS it's running slow. The iPhone 4 is listed as 802.11 b/g/n in Airport Utility in the Advanced/Wireless Clients window. When it was running slow, the signal level was OK (actually good-about the same level as the iMac) but the noise was high so the signal to noise ratio was only between 12 and 20 dB. Also the rate was at 5 and staying there 9 (not sure what the rate number is but it was much smaller than all the others clients).
I turned WiFi OFF on the phone then back on again. When it came back, the signal to noise ratio was better (went to about 30-40 dB, and the rate went up to 58. Then after a few minutes, the signal to noise ratio went back to about 20 and the rate number dropped to 5 again.
I'm not sure what this all telling me exactly, but I agree the iPhone seems a bit slower. It's running quite a bit below my 60 day average for download and uplaod speeds - especially a ways away from the AEBS (new 5th gen). The other devices (iMac and iPad are performing as good and even a little better than their 60 day averages.

Acrobat very Slow performance (50% CPU usage)

My acrobat 9 PRO (9.3.2) has suddently started to use 50% of my CPU usage everytime a *.pdf document is opened.
It is the task Acrobat.exe which is the problem. This results in VERY slow performance and I cannot use the review function without adobe is crashing!
This has not always been a problem!
Does anyone know why this is happening?
I have tried to uninstall and reinstall acrobat, without any luck!
Thanks
Peder

You probably have the same problem as I do. I use version 9.3.3 on a fairly powerful machine with Windows vista. In my case, the problem is related to the weblink.api (http://forums.adobe.com/thread/675941?tstart=0). I also uninstalled, reinstalled, repaired - nothing helps.

Very slow to open new window

How to fix very slow opening window. I have vista 64. Since the last foxfire update it is very slow to open new windows. It can take some windows opening over a minute to open. (yes minutes not seconds)
Once a window is open I can open in new tab with no problem, but not with new window. (I like to have many windows open at a time)
When l click to open a new window either from a link or new window, it seems that nothing is happening. Then clicking to open another one which seems to open faster. Then all of a sudden the first window decides to open after about a minute or so. Sometime it seems to hang longer than other times.

I did try the safe mode and didn't work. I did make iexplorer my default and then back again to foxfire and it somewhat worked. It was work not bad (but not as good as before) until I rebooted and it seemed the more I used it the better it became. Go figure :)
Well I just did another firefox update to 4 and it works perfect and maybe even better than before. (or I got use to how slow it was :) )
Thank You for you quick reply and I'm very happy for the new update... So far so good.

InDesign CC 2014 very slow performance when dragging images and changing text

InDesign CC 2014 very slow performance when dragging images and changing text.
Running on 2010 Macpro 2.4GHz. 8GB RAM. Any solutions? I've read through many forums on this and tried several fixes.

Have exact same issue on my Windows 7 machine. Resetting preferences is a workaround.
So I start InDesign whilst holding down these keys.
Ctrl + Alt + Shift (Windows) or Cmd + Ctrl + Opt + Shift (Mac)
Whilst inDesign is usable again with this fix- I have to do it every time so it trashes all my preferences so NOT GOOD long term fix. Otherwise InDesign freezes and can only be stopped by forcing a quit.
I have manually deleted the preference files and I have created a brand new admin account - but still no luck - will be onto support tomorrow

E50 very slow performance

my E50 is giving very slow performance anyway to tune it up ?? dosn't hangs but its slow ?? any solution ps whats the best antivirus to install in E50 ?

I don't use your same workflow, and I assume you're shooting RAW. However, after I have built 1:1 previews in LR (which takes a LONG time), when I click on a file to decide if it's sharp or not, it still takes 5-10 seconds for each file to load. And my computer isn't slow, and I have the same issue on my laptop, which is new and fast. I haven't seen a satisfactory answer to this problem, nor much acknowledgement from Adobe. My files are from a Nikon D7100 with 24 megapixels, so the file size is likely a factor.
If you are shooting the type of subjects where you use 1:1 previews primarily to determine sharpness, you could consider Photo Mechanic (unfortunately it costs $150) as the first step in your workflow. It uses the embedded jpg files in the RAW file, so it loads 1:1 jpg previews almost instantly. Sports and nature photographers use this product all the time, mostly to delete losers.

Cisco RV 120W VERY slow performance and being unreachable

Hello!
I have strange issues with my RV 120W, which I bought after the recommendations from a Cisco/Linksys pre-sales support. I'm using this unit for SOHO environment with two clients (computers) connected and a few mobile clients. Nothing special and nothing complex. I replaced my WRT610N router with this one on behalf of the VPN features, the RV 120W offers.
Before initial setup I upgraded firmware to it's latest (1.0.1.3).
The issues I'm having with this thing are:
- very slow WLAN performance. And I mean - very, very slow. After doing some analysis I'm having a drop from 10Mbit/s to a stable speed of only a few houndrets of kilos per second. Even less. An average, constant speed test show no more than 50-80 kB/s. And I have a 20/20Mbit link.
- very slow WAN - LAN performance. Although not as slow as WLAN, even LAN is somehow slow with an average throughput from WAN to LAN show no more than 15Mbit/s.
- WAN IP address - host cannot be reached. After setting up the router to be able to echo the PING and be remotely managed, I can achive both services JUST for about 20 seconds after the unit reboots. After those 20 seconds, remote management sessions are timed out and the host is unreachable. But If I reboot the router again, I get it to work again - for no more than 20 seconds.
As this is my first (more) professional router, I'm not really sure if I've got my VPN setup correctly. I cannot get it my VPN to work either and I can't tell if these issues are related.
Any help would be appriciated.
Thanks

Hey Juka,
Sorry your having issues with the rv120w.
I seen that you upgraded the firmware on the rv120w when you got it. I always do a factory reset of the device when upgrading the firmware. I will first backup my configs, factory reset the device, then reload the configs.
Try that since you did do a firmware upgrade to see if the device speeds up for you.
The wireless issues you were describing, I would do a wireless scan using a wireless analysis software like INSSIDER or something like it, that way you can see the wireless channels that are being used and set your router manually to a channel that has no or the least congestion.
Try this and let us know what you get.

ok, stopped syncing in System preferences and even (horror) deleted the file which reappeared in seconds.
now waiting to see if stopping the syncing helps - though computer is now working a bit better, the info on Activity Monitor would indicate it is not a real improvement

Apps like temple run 2 and subway surfers are getting stuck and it is very very slow.My ipod has 2.6 gb free space. What is the problem. I am not getting to know. Even after i reinstalled these apps it is still getting stuck and it is very very slow. Is this what i get after paying so much money for ipod. Is this what i get very poor perfomance.

Periodically double click the home button and close all the apps in the recently used dock. Then power off and then back on the iPod. This frees up memory. The 4G only has 256 MB of memory.
Next
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Restore from backup. See:
