100% CPU Usage, Sound configuration Error and Unknown Error (0xE8000001)

Hi, I just bought a iPod Touch - amazing iPod I must say.
Pluged it in to my Windows Xp to sync some music. (I've been using iTunes for several years now and just upgraded from a 1st generation iPod nano to a 16 Gb touch).
It connected very well and I was ready to sync but then I made a stupid mistake - I updated iTunes to be sure that every thing was up to date.
After the update I get an error about my sound configuration (I've tried uninstalling QuickTime and installing again - didn't work). iTunes open up and starts to sync and now a second issue apears. It uses all of my CPU - flatlinig at 100%, so I cannot use my computer at all. It is now syncing but extremely slow - one song takes about a minute. Now the iPod touch starts to say these weird sounds and rebooting every 20 seconds or so. Finally I get an eroor in iTunes saying that there has been an unknown error (0xE8000001).
So I'm stuck with iTunes not working and no songs on my iPod.. :o(
What to do..?

All programs using 100% CPU, freezing, crashing, -10810, -600, and -1712 errors

Okay, so. I have a Macbook Pro from December 2012, a little over a year old.
Version 10.9.1, running Mavericks
Processor 2.4 GHz Intel Core i7
Memory 8 GB
Startup Disk - Macintosh HD
I can send more info if I need to. I'm a graphic designer using Photoshop, Illustrator, and InDesign usually simultaneously, as well as Spotify, Messages, Sparrow (mail), Stickies, Tweetdeck, and Evernote. I also use a wireless mouse, drawing tablet, and second screen. This has never been a problem (I mean, my old computer had 4 GB memory and handled these programs just fine, except for Final Cut Pro 7) up until recently.
For the last two months, my computer has been seriously out of whack.
I'm constantly having to refresh finder
Every time I open Google Chrome, all of my extentions crash immediately and any website I try to go to is extremely sluggish (but Safari works)
The dock freezes
Constant error messages: 1712, 10810, 600
Audio fails randomly
Overall, the problem seems to be that I can't do more than one thing at a time -- I can't take a screenshot if more than two programs are open, I can't open DMG files, I can't open Spotify if any Creative Suite program is open. I've been watching the activity monitor, and it seems like each program is trying to use 100% CPU, which doesn't seem right. I have to close every program to work in Photoshop, which makes me miss calls and emails.
I've tried restarting in safe mode, verifiyng the disk and repairing permissions, I used time capsule to restore to a time before it was happening, and restored my user profile in Chrome. I'm at my complete wit's end trying to figure this out! I feel like my next step is to just reinstall my OS completely, but that would be a major setback for getting my work done, and I'm not even sure that would work.
I've looked on other forums and it seems like the Mail app typically causes problems, but I don't even use it, I use Sparrow.
PLEASE PLEASE PLEASE HELP

Launch error -10810 in Mavericks
I have the same issue since a couple of days. Nothing that I found in the community (rebuilding launch info using Onyx or manually deleting the apple.com-launch prefs) has helped me so far. Only some apps are affected (PasswordWallet 4.7.4 among them).
I can launch it once and it will run fine as long as it’s open. Next time it refuses to open displaying the error -10810 message instead. I trash the app and use a fresh one off the vendor’s dmg file I downloaded and the sequence repeats.

100% CPU usage when importing cd and downloading from store, please help!

I am using itunes 8.2.1.6. The problem is that whenever I import a cd or download any music from the store my cpu runs at 100%. I have a pentium 4 (which manages nicely with any other task, even importing cd's with another programe) with 3gb RAM.
Is anybody else having this problem? Does anybody know how to fix it?

Distiller 8 and 9 both locking up, 100 % CPU usage

Not sure if its related, but probably, since it happened right after...I just transferred everything from my quad core mac pro to my new 8-core Mac Pro. Everything went well, but now Distiller 8 starts and then sits and gives the beachball of death, and one of the cores shows 100% cpu usage. (I have that utility that shows memory used, CPU usage, etc.). I hadn't bought Acrobat 9 yet so I downloaded it and installed, and Distiller 9 does the EXACT same thing. The ONLY thing I can call an "error message" is that I can see in the window after it launches is "Error in /Library/Application Support/Adobe PDF/Settings/PDFX4 2007.joboptions:/CheckCompliance out of Range."
That message may have been there whole time, even when it worked, though. I don't know. At any rate, I need distiller working! Any ideas?

Glad to hear all is well. Preference files can cause big problems. Eons
ago, in the 1980s, I used a communications program called Red Ryder. I
loved the program. After it was updated to a new version (it might have
been called White Knight by that time), I started to have terrible
problems. I wrote to their technical support. They couldn't duplicate
the problem. It couldn't happen etc. I eventually got a little hot under
the collar. After all, if I couldn't use my modem, I couldn't check my
email, etc. It turned out to be a problem with my preference file when
converted to the latest version, that was causing the problem. Since
they always started with a new preference file, they couldn't duplicate
the problem that was obvious to me.

Server 2012R2 Windows backup 100% CPU usage and no backup

Hello!
I have a problem with two VM´s on a HP Proliant ML350p Gen8, that has Windows Server 2012R2 operating system with Hyper-V role installed.
Both VM´s are also 2012R2, one is DC/DNS/FILE/PRINT and the other one is Exchange 2013.
The problem itself is that, when Windows backup (wbengine.exe - Block level backup engine service) inside VM starts, it uses almost maximum CPU resource, so the VM´s CPUs are 100% used. Backup itself is not working, there is no network trafic. Only
way to get rid of 100% CPU usage is to restart the server.
When i start backup manually (Backup once - scheduled backup options), it is working and the CPU usage is around 20-30%.
One VM (DC/DNS/FILE/PRINT) has 2x vCPU and Exchange has 4x vCPU.
The problem started suddenly, the backup were performing slowly and failed.
Backups are scheduled on different time. Host level Hyper-V backup of VM´s works without any problem.
The backup location is Synology DS414 NAS and the servers are set up using iSCSI, for connecting separate backup lun´s for each server.
The Hyper-V host and both VM´s are patched up-to-date. Ofcourse i have tried a lot of restarts, looking event log, VSSADMIN - cannot find any errors...
The network setup:
Hyper-V host has a team of two physical adapters, that is set up with a external virtual switch (shared with management operating system) and used by the VM`s normal network trafic.
Hyper-V host itself is using separte physcial network card, for connecting with iSCSI to Synology NAS.
I tried to set up another physical network card on the host and create a new virtual swich, add extra virtual nic to VM`s and use this for iSCSI traffic for Windows backup and it didnt make things better.
I need to find a solution, because i cannot restart the server every night for the backups to work.

Recently FireFox often has been causing 100% CPU usage and locks up until it finishes the process (various ones). Clearing cookies/cache didn't help. Any ideas?

Windows 2000 SP4, 1g RAM, Firefox 9.0.1
We keep IE6 and Firefox open simultaneously for 2 different mail accounts. Firefox was always much faster even with 3 or 4 tabs open, but for the past couple of weeks when trying to update a screen the CPU suddenly goes to 100% usage and of course nothing will move until the particular process is finished. Closing one or more tabs does not help. If I close Firefox completely with Task Manager CPU usage goes back down to nil. After restarting Firefox CPU usage may or may not go back up depending upon whether it tries to continue the previous task that was locking it up.
It did not do this with Firefox 3.6 but then again it didn't happen immediately after updating to 9.0.1 either.

100% CPU usage occurred most often toward the end of the working day when busy trying to print on-line postage. We don't have any memory-consuming plugins but according to the knowledge base articles Firefox memory usage can gradually increase during the day even if you do nothing. It seems that may be the problem so we close and restart Firefox more often now as that usually fixes the problem. However, if we get stuck on a particular website update that causes the CPU to to go 100%, we can always start Firefox without previous tabs so the update will stop, or simply use a different browser until we have time to let the computer play games with itself.
So our workaround of restarting Firefox turns out to be the final solution (until we find something better - will post it if we do). Vic

100% CPU usage, causes background music to stutter//pause

Hey, I asked this question before but didn't find the answer I was looking for.
This issue happens when drawing with the brush (before lifting my wacom pen for the lines to get optimized) or any action where calculations are being made (like skewing). As I'm drawing lines, the CPU jumps to 100% usage and my sound (playing off a USB sound card) stutters or pauses. Once I let go of my action, CPU usage comes back down and music resumes. I just installed new drivers, but the problem persists. This happened before using a soundcard as well.

K7N420 100% cpu usage

Apologies in advance for a long post but I'm stretched beyond my technical abilities to solve this thing. I was running a virus scan a week ago (no issues, it had just been a long time since I ran one) and while I was away the machine restarted itself when it shouldn't have. It was waiting at the redhat login (dual boot XP and redhat) when it should have been waiting to tell me the scan was done in XP. It never booted properly again. The HD reported fatal unrecoverable errors. I bit the bullet and replaced the drive with a Maxtor 80G 7200rpm drive and loaded XP Pro with no issues. Loaded Norton, updated it twice and proceeded for Windows updates. No issues, device manager has no conflicts. HOWEVER, the machine is running no apps (they aren't even installed!) and taskmanager reports 100% cpu usage and no processes running except system idle which jumps from 97 to 99% repeatedly. Somehow I managed to revive the original drive (wrote zeroes to it and ran scandisk several times and it reports no errors now) and tried it with the same problem. I've gone so far as to install 98se (yuck) on the original WD drive and it is using about 28% cpu, again with virtually nothing installed. I ran stinger off a floppy as well as Norton several times so the drives and MBR would appear to be clean. The RAM is appearing properly on both OS's and always no applications running and no processes showing as using anything. I'm stumped.
Any advice is welcome.

GlennVidia, first thanks for helping this dumbass out. I ran the memtest overnight with no issues. I just reinstalled XP on the new Maxtor drive. I am using the 2.03 drivers. I just installed PCAlert and it shows the following voltages: Vcore: 1.74, 3.3 is at 3.34, 5 is at 5.03 and 12 is at 12.18 with a cpu temp of 118F. I have installed no other apps including anti-virus. The cpu usage is bouncing between 44% and 65% cycling every second...you can set a clock to it. (Hopefully that triggers someone's memory?) No processes showing as using resources in task manager besides system idle and an occasional hit for task manager itself. Device manager has no issues. I changed the ide cable and reseated all cables to and from the mobo.
You mention usb...I'm not using any usb devices but will gladly kill it in DM if that is what you are suggesting for a test run.

100% CPU Usage caused by HMI

Hi everybody:
I'm working with LabVIEW DSC 8.2.1 in a system that monitors many variables of a plant, such a typical SCADA system. For this reason, the use of the graphic tools is highly used on the development of this system. Everything works fine, but I have only one problem.... the usage of the CPU.
When I am working on the development system I (not the executable) I start the application and after the variables are initialized and every process has started and are running , the CPU usage is raised around 90 - 100%. After a few days investigating the reason of this, I realized thay when I change the view on the screen to another view, for example the block diagram of the application, while the application is still running, the CPU usage goes around 15 - 25%. I've tried these many times changing the view from Front panel to Block Diagram and viceversa and the result is always the same: Front Panel= around 100%; Block diagram or another view (other applications MMIs, or Block Diagrams, etc.)= around 20%.
Another thing that I realized is that the other view (different to front panel) has to fill the entire screen to work the way I'm telling before.
When I build and run the executable, the usage of the CPU is the same... (around 100%), but I can't see any other application, because the application built is the shell of the OS, so no other views are available.
I don't know if there's some other consideration to take into account about the HMI when creating an application, and I'll appreciate very much your help.
Thanks in advance!

From http://100cpuusage.blogspot.com/
100 Percent CPU Usage when you run programs after you install Windows XP Service Pack 2
CPU Usage 100% Symptoms
When you run some programs, the CPU Usage meter in Task Manager may indicate CPU Usage 100%. When CPU utilization reaches 100 percent, programs will run very slowly or stop responding (hang) and your computer is freezing or crashing.
Noteress CTRL+ALT+DEL to view CPU utilization, click Task Manager, and then click the Performance tab.
These symptoms occur after you install Microsoft Windows XP Service Pack 2 (SP2).
CPU Usage 100% Cause
These problem occurs because of the user interface code that is included in Windows XP SP2. The high CPU utilization is caused by the additional overhead that occurs when the IsWindow function is called by the user interface code.

Queue consumer stops with 100% cpu usage

I'm trying to use Berkeley DB queue with transactions. When I tested what happens when transactions with DB_APPEND are aborted I found that while it works and DB_CONSUME correctly skips over rolled back records, unfortunately extents that have those records are never deleted, which causes database to always grow. Next I tried DB_CONSUME with database opened using DB_INORDER flag and it seems there's a serious regression in Berkeley DB that causes it to loop indefinitely with 100% cpu usage when it encounters a rolled back record. I tested various versions and found that this bug doesn't happen with 5.1.29, but it is reproducible with 5.2.42, so this regression might have been introduced in 5.2. I have also tested 5.3 and 6.0, and both have this behavior. There may be something wrong with the way queue records are rolled back, one indication of that would be that in 5.1.29 doesn't have neither of the two problems I found with DB_QUEUE: extents are deleted after being consumed, and there are no issues when consuming with DB_INORDER either.
You can find Python code to reproduce this issue here:
https://gist.github.com/snaury/027a3c546f5b0a62a440
Sorry for using Python and not e.g. C++, but it's a lot shorter that way.

We have looked at the issues and they are valid. We will roll the fixes out for this in our next release of BDB. The test case was very useful and really helped to speed the process up. If you have any questions, please contact me directly at [email protected] Thanks again for bringing this to our attention.

HP LaserJet Pro MFP M127fn - DNS issue, hundreds of UDP connections affects my router 100% CPU usage

Hi all,
We've bought about ten pieces (HP LaserJet Pro MFP M127fn), tested only one the other 9 are waiting for their time to be sent in our branch offices. The MFP works fine, no complains till later that day I noticed that our Mikrotik Router was struguling with high CPU usage, it took me some time to find the issue and it was the new bought MFP. Don't know why but it creates hundreds of UDP connections and almost 100% CPU usage goes to DNS service. As soon as I shutdown the MFP and delete all the connections everything goes back to normal. I've disabled almost all services (HP web service, Ipv6, SNMP, AirPrint, SLP, LPD, WS-Discovery, Bonjour), leaving only Ipv4 but without luck the issue persists. Here are some print screens confirming my saying:

Problem:100 % cpu usage with tcp server dll

Hello,
I am trying to write a dll with labwindows/cvi that allows me to create a TCP Server. This dll is integrated in labview.I created this Dll with example provides by Labwindows/cvi(rtserver.dll).
Description of my problem: when i execute this dll in a "While Loop" in labview,the TCp server wait a connection and 100% cpu usage occurs. However when a client is connect to the server,the CPU is normaly used because the program stop when he meets the timeout of the tcpread() function. I would like to know how i could limit CPU usage when the server is awaiting a client in the labview "While loop".
I know I could use a DELAY() to limit Cpu usage ,but I would like to know if there are any others solutions.
thank you.

i dont know your exact application, but i generally use Q to transfer data to TCP loop in my prgram it helps me in two ways.
1. it automatically restricts the iteration when ther is no data (Less CPU Usage, Less Unnecessary Trafic)
2. Q can eliminate problems arising due to non synchronization of loop

100% CPU usage with XP Cooler from PCAlert4

Any idea why I would be running 100% cpu usage when running XP Cooler from PCAlert4? I noticed PC was sluggish when running it so CTRL+ALT+DEL and under performance is 100% CPU with 245MB Ram Usage. No other TSR's running - several application but under 10% CPU usage without PCAlert and XP Cooler.
I was also wondering if anyone had any ideas on the video? I have the K7N2G with 768MB DDR PC 2100 (3x256) XP2200+ 266FSB running 1804MHz - Maxtor 30GB 7200RPM - 350W PSU (raidmax - yea yea I know, dont say a word though LOL) on board video and here is the problem - graphics are great, but they get choppy - running NFS HotPursuit 2 at 32bit 800x600 (doesnt seem to matter even when running 16bit 640x480still does it.) what setting am I missing? Thanks in advance.

Deathstalker (Richard),
I did what you suggest in memory management and also changed out the mem on the board - it did make a difference, not as much as I had hoped, but it did.
Raven,
I have used Fraps in the past, forgot about it, but went ahead and downloaded it to get a better look.
To the Both of you,
Thanks so much for your replies, sometimes it just takes someone outside looking in to see the things overlooked. But I went ahead and also ran all of the latest updates for the board (semi new system and I only installed with the CD that came with the Mobo) and everything is running better than expected. Thanks again for your thoughts - keep 'em flowin, it's amazing whom we could help. Take care.

Music store & 100% CPU usage

I've had this problem on my newly built computer, and my older machine. When I browse the iTunes music store, the status bar on the top will often move like it's opening the music store, but it'll do this for a long period of time (several minutes) and iTunes will work, but the music store will not load, and you cannot click the 'X' to stop the contacting of the music store. During this time if you open task manager, iTunes uses 100% of CPU resources. If you close iTunes it still uses 100%. you have to end the process in task manager in order to make it stop. On occasion the music store will work to view maybe one album, but if you search for another album, or click another link it'll do the whole not-responding-100% CPU usage cycle again.
All drivers are up to date and like I said it's done this on two seperate computers of mine on the same iTunes account. I also have a laptop and the music store works completely fine on it. It's only on my desktops that I have this issue.
Some specs on my machine if this will help
Asus motherboard
AMD Athlon XP 4000+ processor
2gb Kingston 184 pin DDR ram
Seagate SATA II 160 GB HD
Windows XP PRO service pack 2
thanks for your help!

I'm only guessing here, but perhaps iTunes is having a conflict with another application. If you are anything like me you probably install your favourite applications on all your computers. As a shortcut to troubleshooting, perhaps consider an application you have installed on the desktops, but NOT on the laptop. Then try uninstalling that application from your desktop computer and test iTunes.
