Explorer Using 99% Of CPU Usage / Get Blank Screen
Jan 28, 2003
An interesting problem has come up recently. If I try to open My Computer to access some file or what not, instead of bringing me to the list of drives, I get a blank white space. It never loads. From here, I can Cntrl Alt Delete and clearly see that the CPU usage is at 100% and that it is Explorer that is taking up 99% of it. I end the task of opening my computer, and then I try again and everything is fine until maybe five minutes later when the problem reoccurs. I have run virus checkers and adaware and neither has shown any problem
I'm running XP pro SP2. I have a gig of ram and my mother board is an Intel D101GGC. My CPU is Intel Pentium D 920.
If I use Windows Explorer to go deeper than the first level of any tree, CPU usage goes to 100% and stays there. I've disabled System Restore because it wouldn't let me go back in time anyway and this program is a known resource gobbler. Didn't help. I've attached a hijackthis logfile to see if anyone recognizes a Trojan, etc. I would appreciate any help at all.
After a few days of work, the user cannot open new windows explorer or other application windows. Nothing happens if she tries to. If she closes one window, then she's able to open a new one. The "allowed" number of opened windows varies from time to time, sometimes being as low as 4, but sometimes around 10 to 12. The performance tab in the task manager is completely blank (see screenshot). Some Windows explorer menu bars sometimes are blank, and a windows logo appear instead of the menus (see screenshots). Rebooting fixes the problem, but it comes back a few days later. The laptop is part of a domain, running generally the same applications as other desktops and laptops in the domain, running the same antivirus, etc. The virus definitions are up to date, and a full scan has been run. Even stranger is the fact that when it happens, Windows XP doesn't even seem to be unstable, nor does it crash in any way. Just seems as if there was a limit on the number of processes or handles or threads allowed to run.
Laptop: IBM Lenovo Thinkpad (model 63716NF) CPU: Core 2 @ 1,8Ghz RAM: 2 gb OS: Windows XP sp3. Swap file: initially set to 2046 mb and max is set at 4092 mb Processor scheduling and Memory usage are both set to "Programs"
I have been searching the web for solutions but cannot find any forum post describing the same problem. Thank you for any help.
I recently got my HP back from Best Buy, where they had to 'clean' it due to spyware, adware problems (no more Kazaa for the kids). Evidently, I had the nail.exe file, in addition to others. After 12 days, they gave it back to me, completely clean (according to them), with Norton Internet Security installed - in the process they lost all my e-mail files, but oh well. Anyway, I haven't had the darn thing back 2 weeks and I'm getting 100% CPU usage, with explorer.exe being the main hog. When I delete it in the processes list, the CPU usage goes down to 4%. I really don't want to take this thing back to BB for them to keep for another 2 weeks.
Windows has been running really slowly sometimes and i've ran spybot, adaware and a couple others and its still running slow. when i went into task manager it said explorer.exe mem and cpu usage was very high; cpu was 99 and mem was over 100k
My computer is a Dell Dimension 2400, 2.2 GHZ and 256 RAM.is constantly running at 98-100% CPU usage in task manager. I have run ad-aware, spybot, AVG, microsoft antispyware, checked my HJL for an strange occurences, ran chkdsk, This seems to be a pretty large problem, since i've been spending considerable time on the internet trying to find solutions, but there doesn't seem to be a whole lot out there.
Win Xp - Service Pack 2, I suspect the problem lays with a trojan dropper. In fact I'm certain. At the moment I am getting a trojan dropper putting random files into my temp internet files every 3-4 hours - the latest file being SQL.AVG?? Norton deletes it as soon as it appears but I'm certain its causing my 90-100% CPU usage on explorer. exe. Its been doing this for about the last week.
I've got all of these installed - ZoneAlarm, Norton, AVG 7.1, Ad-Aware Se and even Microsoft Anti-Virus. I updated them all and went into safe mode and ran every single one of them on full scan and none have found the culprit. When booted back into normal mode the trojan dropper has started again and cpu usage back up to 100% for explorer.exe. Basically everthing crawls after 5 or so minutes of reboot.
when opening folders from desktop computer slows - when task mgr opens it shows explorer.exe at 100% - below is logfile of HijackThis - any help would greatly be appreciated.
Windows Explorer consumes all available memory and cpu time until performance becomes pathetic or the system crashes. I have been running everything from the Task Manager for the past 5 months. I have Dell 2400, Win XP home, Norton AV, Firewall etc, MS anti spyware. Have run every AV scan know to man and MS antispyware and others including Registry editors.
I have been having some major issues with my mouse recently - anytime I so much as move my mouse (clicking does nothing) My CPU usage for Explorer jumps up, immediatly to 50% and if I make any slightly erratic movements, up to 99% It causes major issues in quite a few games, as well as totally screwing up any multitasking I wish to do
My computer started running extremely slow. When I check the task manager it notes that the CPU usage is spiked at 100%. I checked to see what is using most of the CPU and its "explorer.exe" using about 99%.
I am using windows xp pro with a 2.00ghz celeron cpu I also have 2gb of ram, lately my pc seems to be slow and explorer keeps crashing causing the desktop to reload if i look in task manager my cpu is almost always at 100% I have done a virus and spywear check but that found nothing
Whenever I open my folder with video files win. explorer CPU usage jumps to 50% although I didn't watch any clips When I close the folder CPU usage remains the same and there is no open applications. I am running XP SP3 with all the current updates.
Windows seem to have a REALLY big problem when it comes to reading AVI files. It seems that when you click on an AVI file in explorer, it'll try to read the entire AVI file to determine the width,height, etc. of the AVI file this is displayed in the Properties window. Now the problem with Windows is that if you have a broken/not fully downloaded AVI file that doesnt contain this info, Windows will scan the entire AVI file trying to figure out all these properties which in the process will probably cause 100% CPU usage and heavy memory usage.
When I run IE, Outlook or several other applications, which I can't run at the same time or the computer works forever to do anything, my CPU usage jumps to 100%. Does anyone know how to fix this problem?
All the .html files on mywindows XP sp2 machine have been renamed to .htm and further when I try to rename them, the explorer CPU usage suddenly increases to maximum. But, some files gets renamed and others can't be renamed at all. And, for those which cannot be renamed, I get a pop-up error message saying "file is being used by another program and cannot be renamed.", and that's when explorer starts using all of CPU and system gets very slow.I have already done full system scan through Kaspersky and Malware Bytes Anti-Malware, but they have simple turned out to be futile.
Does explorer.exe and svchost.exe seems to be using a lot of memory,or am i just being paranoid?
Its not usually like this though:
I have also included an Hijackthis report: Logfile of Trend Micro HijackThis v2.0.3 (BETA) Scan saved at 3:00:25 PM, on 5/28/2010 Platform: Windows XP SP3 (WinNT 5.01.2600) MSIE: Internet Explorer v8.00 (8.00.6001.18702) Boot mode: Normal
I'm having a problem when i start up my comp. after logging into my user account, the monitor sorta "blinks" periodically.. as in, the wallpaper is there, but all the icons disappear. However, as soon as i open Norton Antivirus , the problem stopped (until the next time i restart the computer and log on).
On loggin in, I checked the cpu usage with taskmgr, and foud that it was goin pretty high (jumping frm 10%to 60% or 80%).. when i checked out the running processes, "EXPLORER.EXE" was taking up around 95% or so.
I have a Toshiba Satellite notebook (about 18 months to two years old) running XP Pro, and frequently I encounter a situation where, with no programs running, explorer.exe "cycles" in activity and CPU usage - for example, from 30,000 K Memory Usage to 50,000 K to 70,000 K to 90,000 K (over the course of 10 seconds or so), then drops back down to 30 or 40,000K and starts over.
Very similar to the following problem but i do not have a raid, and it seems that this PC has a raid and i don't, plus it was never really determined what the actual solution was.
The basics: XP Professional Boot up screen, right before the windows loading screen, or direct after the F8 Menu if you hit "Start Windows Normally..." it will just lock up, no HDD activity, blank screen. now BSOD, nothing.
All 3 safe mods work fine.
Ran chkdsk /r in recovery. Ran proper fixboot procedure.
Went into safe mode and checked the event viewer.
The only concerning message i got was: The following boot-start or system-start driver(s) failed to load: AmdK8 Fips nod32drv
Formatting really isnt an issue since i can back up anything i need through safe mode. However its just the fact that the Windows gremlin has struck me again and i must defeat it once more.
I highly doubt this is a hardware issue as it is more of a driver/software issue.any help?
When i turn on,first Windows screen appears,then a blue screen blinks,then hp screen,then a blank page with cursor on the top left,then a screen with the message"we apologise for the inconvinience but Windows did not start successfully.there was a hardware or software problem.I tried to run it in Safe mode, Windows normally,last known configuration but no luck......Then someone suggested to Get into the Recovery Console by making a Recovery CD with ISO image but the machine is not responding to any of it.Is it with CD/DVD ROM drive or any major hardware problem???...I ran a self hard drive test and it seemed fine
I was playing a game and I rebooted my computer. When i went to start it it went to the a blank blue screen before the account screen in the beginning of XP. I know i can restore to new but i will have lost so much information that it would take about 3 months to retain it all back. It says it can not find operating system. I need help in a serious way. all advice and solutions are requested.
My explorer has gone nuts. It will run programs, run shortcuts to anything but folders and the real problem is that it wont open a signal folder either by explore or open commands. I've reinstalled WINXP off the CD as update, nothing happened. I've ran the steps listed in the last forum. Nothing has worked. I'm desperate. I'm running WinXP Professional on a basically 7 month old Dell comp with 512RAM and a 2.4 GhZ Pentium in it. I'm lost at what to do.
when i boot up my computer and log onto a user, the wallpaper shows up and that is it. I tried pressing CTRL + ALT + DLT but nothing shows up, except for the mouse. I am not able to access anything on my computer except for when i'm in Safe mode. So I tried system restore and rolled back it back to previous checkpoints. It worked for a while, and that was it.
I turned on my comp to find a blank desktop. The wallpaper appears but there is no taskbar and no desktop icons. This is the same for each user on the system. I was able to start the task manager and run a command prompt from there which allowed me to run some programs but not windows explorer. My system restore also seems to have been turned off and all restore points removed.
I managed to run a virus check with AVG free edition which detected an executable file 'charlie.exe' in the my pictures folder for two of the users saying they were trojans 'trojan horse backdoor.generic8.fjs'. AVG deleted these but, as I suspected, did not cure the problem. I have also run adaware but this never detected anything other than a handful of tracking cookies. I have downloaded Hijack this V2.0.0, but will wait for advice before posting a log.

i'm having to boot into windows xp. on power up sytem goes through the windows xp splash screen (with progress bar) and then instead of login prompt it goes just into the blue screen with moveable mouse pointer arrow.
issue seems to be similar to: http://forums.techguy.org/windows-nt...o-startup.html http://forums.techguy.org/windows-nt...p-problem.html but recommended solutions didn't help so far.
symptoms just before issue - was not able to run use some system features - utility to turn off the display, utility to bring up battery info - everything was working fine before this
what i've tried: boot to Last Known Good Configuration - resulting in the same blue screen
boot to Safe Mode / Safe Mode with networking / Safe Mode with comman prompt - resulting in blank (black) screen with "Safe Mode" in the corners and moveable mouse test the hardware (hard drive / memory etc.) via build in PC Doctor - all seems to be working i am able to use bootable XP CD from other machine to get into Recovery Console i am able to boot to simple live XP using BartPE-XPE usb key and access the hard drive
I've messed up something to do with Internet Explorer. First of all, when I open IE all I get is a blank page. No error message or anything. I try to go to a site and the address bar stays at "http:///". I tried repairing my Windows 2000 installation and it didn't help at all. Now it's reverted back to IE5 and Outlook Express 5. So I tried to reinstall IE6 by downloading the installation file and running it. I get the error message:Error creating process <COCUME~1WILLIA~LOCALS~1TempIXP000.TMPie6wzd.exe/S"Cocuments and SettingsWilliam OverbyDesktopIE6.0 FullIE6SETUP.EXE">. Reason: The system cannot find the file specified.
I was just in itunes adding about 12 songs when my comp not only froze, but it also gave me a blue screen. I didn't copy the exact number/code it gave me, but it did say kernal_data_inpage_error. Right now, it seems fine. Not blazing fast, but normal. I had itunes opened about 10 minutes ago just after restarting and it took a good 5 minutes just to cntrl alt delete and use task manager to close it. I also got a blue screen once over night when trying to use MyDefrag to defrag my larger slave drive. It worked fine in defragmenting my smaller master drive.
