CPU Usage 100%, PC Keeps Crashing, Svchost.exe?
Apr 14, 2007
Soon as i turn it on the antivirus starts up and my broadband connects then it freezes, a few times i've managed to open the task manager and i notice that on the CPU Usage History it it constantly at 100% and when i go onto the Processes tab instead of System Idle it is SVCHOST.EXE that is using all the CPU.
I thought it was a virus so i started my PC in safe mode and run the virus scanner, it found 3 Trojan Horse Downloaders, one even named itself CMD.exe which i thought would of cured the problem but ive turned it on this morning and it is still the same, it seems a little better and lasts longer before crashing but it still crashes eventually.

I have this strange problem. Randomly some program or another would stop responding while using around 50% of processor usage. If I kill that unresponsive processes then the next used processes (say I switch to thunderbird window thereafter, or back to opera) then that next program would stop responding at 50% CPU usage. The solution is just to restart windows xp. However, if instead of killing the unresponsive program, suspending it (I use process explorer) would free up the CPU usgae, and everything woud continue running smoothly!

The computer is nonresponsive for the most part at first. I click on the start button and nothing happens, but if i click on any desktop items they become highlighted because I clicked on them, but if I try to open them, they don't open immediately. After about 2-3 minutes of doing nothing, everything that I wanted it to do happens all at once.
When I open task manager, the thing that is taking up all of my CPU is this thing called SVCHOST.exe; there are 5 of them running - 3 for system, 2 for network service, and 1 for local service. While the computer has an episode, one of these for the system will use 99% of the CPU. That is when things are nonresponsive and slow.

checked windows task manager...it appears to be svchost.exe (not svchosts.exe). Is this a virus or spyware because i have 3 different ones on system?

Every time I'm on the internet svchost.exe takes up half my CPU. I can't browse, I have to constantly end svchost.exe so that I can sluggishly switch pages then in seconds it pops back again. Svchost.exe is somehow connected to my internet connection because i need it to use the internet yet its not letting me, its really frustrating, I've been beating my face on my desk because i cant figure out whats wrong. I've scanned my computer with AVG, malwarebytes, Spybot S&D, and Ad-aware.

I have recently become annoyed at the high memory usage of the svchost.exe process. I have 8 of these services running at the moment. I havent had reason to complain until recently when they seem to be using more memory than necessary. I might just be over reacting here but perhaps someone can verify it for me. I have included a hijackthis log at the bottom.my system is running WindowsXP SP2, Asus K8VSE deluxe, Athlon 64 3200, 1.75 GB RAM, updated via drivers and windows updates (except one that just came in and I havent done yet).These just seem like too much memory for these. I have check at blackviper and didnt really see a lot of things I could turn off. I could be wrong though.

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:

I have asked this before, but on startup, I have several processes named svchost.exe that run on startup. One of these is a network service and every time, this particular one uses 50% +/- CPU. Apps will not open, nothing will function correctly until this is terminated.

Both svchost.exe + wuauclt.exe's memory usage occassionally increases rapidly even if my laptop is idle. I have to terminate wuauclt.exe manually (through End Process in Task Manager) in order for the 'Commit Charge' to return to late 300/early 400M figures. If my 'Commit Charge' is 5XXM or above, if I plug any USB devices Windows XP won't recognise them. I have to terminate memory consuming programs (e.g. Firefox), restoring the Commit Charge to 4XXM, then Windows XP will recognised any USB devices I plug in. However, if I plug any USB devices right at the beginning when I turn on the laptop, I won't encounter any problems. Why is this?

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.

For about two weeks now my computer keeps crashing every time I turn it on. At first it wouldn't turn off when I go to shut down, then afterwards, it won't boot up normally. I turn it on and it freezes, every time, I have to hold down the power button, wait for a few seconds then try again. It will then boot up or ask to boot up from the Last Known Good. Either way, it will boot, get to the WIndows menu and sometimes crashes again and reboots automatically. I've reported this to Microsoft each time, and I've already re-formatted and re-installed Windows and the problem still persists.

My CPU is constantly 100%. My computer is terribly slow and may applications suddenly crash without warning. Firefox and print shop are the main crashers. I did a clean boot and after that the speed was absolutely fantastic,no crashes and very little CPU Usage. However, as soon as I added any of my essential applications(logmein,trend micro,Google desktop,linksys) the same problem was immediately back. I disabled these programs one by one and it still happens.

I've been experiencing random crashes of Explorer.exe, and when looking at the Application window of the Event Viewer it details this:
Faulting application explorer.exe, version 6.0.2800.1106, faulting module ntdll.dll, version 5.1.2600.1106, fault address 0x00001d24.
I searched around the internet and found no real answer, there's some solutions which require using the Data Execution Prevention tab with SP2, and adding explorer.exe to the list. I plan to try this, but I was wondering, would replacing ntdll.dll with another computer's possibly fix the problem? It's been an annoyance now for a month, and I've ran every virus scan, every spyware/malware/ware-ness program known to man, to no avail.

My laptop keeps on crashing, whilst playing on world of warcraft, my laptop just completely switches itself off without warning. As of yet, has only crashed whilst playing wow. This is also not due to overheating, as im using a separate fan unit, after heat issues arose Using an acer laptop - aspire 5610 - with Xp proffesional, media center. Also sometimes, after restarting the laptop, and selecting the screen name, it comes up with my background wallpaper, but no icons, start bar, etc - only way to get rid of this is turning the power button off. Included a hijackthis log (hope i've done it right.

I have been having problems with my computer crashing and switching itself off when I am running my Nortan Internet Security full system scan. It gets to about 8000 files scanned then it crashes and switches off. It has happened at other times today when Norton Scan has not been running as well. I sent the error report and it came back with what is written below.
You received this message because a device driver installed on your computer caused the Windows operating system to stop unexpectedly. This type of error is referred to as a "stop error." A stop error requires you to restart your computer. More information ...

I had bought a Compaq Presario 5013wm a few weeks ago. The system came with Vista. I was having a lot of hardware issues with network and gfx card, so I opted to install XP. Well, XP wouldn't install because I had no floppy disks to load the raid drivers with, so I went under the BIOs and changed it from RAID to IDE. So now XP is on and everythings working... kind of. The problem I seem to be running into is some seemingly random crashes. From what I've noticed, they only happen while playing a game and, very rarely, when playing music. Sometimes I can play for hours and other times, just a few minutes. The graphics card is a Geforce 7300GS and it has the latest drivers along with the audio. Checked the temp and it seems to stay between 64-67C while playing a game, which I hear is normal for my card. The BIOs is still in IDE mode.. not sure if thats an issue.. can't turn it to RAID without a floppy drive -__-;. Upon thinking of it, I doubt that's the issue as the few times I was able to play before uninstalling vista, I recall the same freeze.

This started since I started overclocking my graphics card. I thought might be it but a new symptom occured.First, it started freezing and crashing randomly and I thought it would pass if I stopped overclocking. I took out my graphics card and hoped it would stop.It got worse. What happened was I tried to turn on my computer and it crashed while starting up everytime. I had a bunch of recovery discs so I used them because they worked everytime in the past. Bad idea. I started the recovery process and as soon as it started, my computer crashed. I turned my comp back on but it said there was no OS installed. I tried reformatting and my computer crashed in the middle of that too.At this point I'm really pissed at my computer. I can't reformat. I can't recover. I can't even start up my computer up to the desktop.

Everytime I try and schedule a TV recording in Media Centre (freeview) on my PC, this message appears. If I click on OK to terminate it, it generates a crash error report. I always submit the reports but its not helping the situation. If I click cancel to debug it, this message appears. Can anyone shed some light into why I maybe experiencing this issues? I havent had any problems before like this but I recently changed my broadband provider to Talk Talk but I am very unhappy with the preformance and strength on my wireless network so Im going back to BT
