Windows Explorer using 50% of my CPU, causing all on my computer to take much longer. Help
I use Windows Vista and recently the machine has been very strong, so I watched my task mamager and he said I was using 50% of my CPU, meanwhile, I had no programs running. I checked the process tab, and he said all the 50% was used by Windows Explorer. Is this right, if its wrong how can I solve this problem?
Try a clean boot, or boot into safe mode. The behavior persists?

Hello, my computer is having a lot of problems, which started last night. Here are the things that are run:
-Windows Explorer does not respond
-Computer cannot disconnect correctly: down/restarts when I close the computer says "disconnect" for hours.
-Cannot use the system restore and may not even start from Safe Mode command prompt
-Safe mode does not load
-No applications work, apart from web browsers, and AVG.
-Cannot access the drivers, to make anything back.I added not all strange programs and I do not think it is malware, but I can't actually run my anti-malware program. My computer is running really hot, what he has always done and I keep it high and the fan not covered (I'm broke, can't afford a fix of the computer, or the new computer). Please talk is profane. I'm not all that techno. THANKS FOR ANY HELP!
The model is:
M8622 laptop Gateway
Vista Home Premium 32 BitSo I reinstalled everything, and even though it's a pain, my computer is normal again! Must have been a virus.
Thank you very much for your help!

When you plug the hard drive, Windows Explorer says does not not and closes all applications
When I connect my hard drive (which has more than 70 films) my watch windows Explorer does not and it closes all active applications. I can't open my disc... hard help me...
* original title - when I connect my hard drive (which has more than 70 films) my show windows Explorer does not and it closes all active applications. I can't open my disc... help me hard... *.
Hi Adnot
Method 1:
I suggest to connect the hard drive, then try to run the security analysis. You may need to disable all autorun feature, if you use the drive. Then, try to perform security analysis and check if you have any viruses or malware present.
See the link below for the analysis and verification.http://www.Microsoft.com/security/scanner/en-us/default.aspx
Method 2:
You can also perform a clean boot and check if you can open the hard disk properly. To perform the clean boot follow step 1 mentioned in the article below, and then try again check in the clean boot state -
http://support.Microsoft.com/kb/929135
If the problem is resolved check which service non-Microsoft is the source of the problem; referring to article and following the other steps.
When you are finished troubleshooting, follow these steps to reset the computer to start as usual:a. Click Start, type msconfig.exe in the start search box and press ENTER.
If you are prompted for an administrator password or for confirmation, type your password, or click on continue.b. on the general tab, click the Normal startup option and then click OK.
c. When you are prompted to restart the computer, click on restart.
I hope this helps.

AUDIODG. High CPU usage EXE on NEW computer... Please help
Why is AUDIODG. EXE using so MUCH CPU usage? I just bought an HP computer brand new a week ago and from day kept getting Norton notifications file audiodg.exe use up to 100% of the cpu. I googled this searched and searched for help and tried everything suggested as I disabled the improvements in reading, I run the boot, I check to make sure that all THE devices were up to date, etc, etc. Nothing has worked. I am extremely frustrated by the fact that it's a brand new computer and already problems with windows pre-installed. (I am running windows 7) Also to note, that I don't receive these alerts cpu high when you listen to music or anything else, what happenes even if I use the desktop themes pre-installed or multitasking with many files opened, etc. If anyone can help, please advise how can I avoid this file so cpu. Literally hold it the computer where I have to wait to type or open a file or something else. So it's very, very annoying! the computer specs are: AMD processor A6 - 3600 APU with Radeon (tm) graphical HD 2.10 GHz, 6.00 (5.48 GB usable) GB memory (RAM), 64-bit, Windows 7 Home Premium operating system. If anyone can help I'd be really grateful!
Have you tried to disable the improvements on the playback device?
Right click on the speaker icon in the notification area, and select playback devices, select your audio device and click Properties. Go to the enhancements tab and check Disable all option improvements. -
Windows XP does not detect any internet at all despite the computer with the modem to work.
I recently installed Windows XP Professional on my new iMac via bootcamp. While Windows itself works fine, it won't connect to internet at all. Despite being connected to a modem ADSL via a Ethernet cable, and also have wireless internet, Windows does not detect any signal. On the internet in the Control Panel, all connections page that appears is "1394 connection" under the heading "LAN or Internet high speed." I tried several times to put in place a new internet connection through the Setup Wizard and everytime, no internet is detected.
I know that the modem works because all the other computers in my house are fine online, including on the side of Mac of the iMac. If anyone has an idea as to how I should resolve this problem, your help would be greatly appreciated!
Thank you
Daniel
Moreover, these are things I've already tried:
I've tried to manually and automatically set up an internet connection
I spoke with my ISP, the modem works fine
I have re-partitioned the hard drive and reinstalled XPThe "1394 connection" is the IEEE 1394 (FireWire) from your computer. There should be cable system and under the heading wireless connections "LAN or Internet high speed." There is no need to run the Network Setup Wizard or set up a new connection.
Open the Device Manager (Start > run > devmgmt.msc ) and go to the network adapters section. You may need to install the drivers for them.

Skype starts randomly using 20% of my CPU
Every once in awhile (randomly), Skype will start and begin to use 20% of my CPU until I put my computer on energy saving. Specifically, I completely shut down Skype because he always seems to do that in the worst of times (like when I'm in a room with other people and my laptop fans suddenly start to look like a Jet engine). If I try to put an end to the task, she just starts back up again. I noticied it also uses some disk use, but not much.
Next time, in this case I'll try to take a screenshot and to post it here. Anyone has an idea why Skype doing this?
Skypehost.ext is not Skype, it's Windows Messenger 10 iApp. You can uninstall this app of apps in settings.
20% of CPU overheating not your computer load, this can be caused by dust or other obstruction of the air flow. Also, make sure that you have installed windows 10 drivers, including drivers of management chipset manufacturers.

Windows Explorer stops working
Windows explore stop (explore.exe question) it seems only when I try to open a file with associated with Real Player videos. When I left solutions, none are found. I have Vista Ultimate and don't remember having this problem with Vista Premium. I tried many things such as an external hard drive, to reduce the load of memory and a player flash set up as a ReadyBoost. Found a lot of answers about Windows Explorer, but most East of problems with several accidents or other problems.
Any help would be appreciated.
Click Tools and then click Folder Options
On the general tab, click using the Windows classic folders, and click OK.This will cause the explorer.exe avoid making the thumbnail preview on video files that might not be compatible with Vista.
