CPU Usage 100%, svchost.exe using 160000k. Startup half hour

April 14, 2012 at 11:19:51
Specs: Windows Vista, 4 gig ram

The CPU usage is at 100% on my sony laptop, but fluctuates after awhile. One of the svchost.exe processes is taking up over 160,000k. Start up takes between five minutes and a half hour. White and black screens appear and stay for many minutes at a time.

This started a few days ago, when I had run a disk defrag and ran a registry cleaner with Speedupmypc. I deleted the program, in case it was making things worse.
I have tried a clean boot and many other things.

I have also downloaded process explorer, hoping to root out the service that is responsible for the high CPU usage. Svchost.exe is definitely the highest, at over 160,000k, but there are so many services linked to it. I don't know how to figure out which is making it bad.

I would do a diagnostic on the hard drive. there may be one in the bios, or you can take the panel off where the hard drive is and find the maker, go to their website and download their diagnostic utility. Seatools works on most hard drives if you aren't comfy taking the back panel off.

If the computer boots to windows you can use seatools for windows, if it didn't boot you would download seatools for dos and make a cd from the iso download.

If that passes a hard drive test

Try downloading and running malwarebytes and see if that helps out. You can decline the free trial offer it pops up once installed. Update it, run a full system scan and remove selected when finished.

I tried downloading seatools for windows, but when I ran the program, it remained stuck on scanning for supported drives. Then I saw that on one forum it said that SeaTools doesn't work for 64 bit systems. Is that true?

As for malwarebytes, I'm running a full scan now, so I'll see if anything turns up.

Alright, got SeaTools to work, and my hard drive is fine. Also, ran the malware scan, and nothing came up.

I noticed when I compared my laptop's resource usage to my friend's laptop that pretty much all of my processes and services are taking up way more than theirs. Even things like taskmgr.exe. For my friend's laptop, it takes up an avg. .25 of the CPU. As for mine, 10.11. This seemed to be the case with most of them. :/ Though mine fluctuated a lot more. The taskmgr would occasionally drop down to .5. But my friend's numbers remained pretty stable.

Any help with this would be wonderful.

And yes SeaTools works on x64 systems

What are the specs of your system? A quad core with 8g of ram will be using notably less cpu and ram than say an Atom processor in netbook with 1g ram......it's relative?
For one you could try booting into safe mode by tapping F8 key when starting up the computer.....choose safe mode with networking, does it run much better in safe mode?

Hey, sorry for the late reply.

My computer is a Sony Vaio VGN-FW390. Intel Duo Core P8600 2.40Ghz

I'm running windows vista 64-bit, 4g of ram.

But, my system never used so much CPU before. I'll test the safe mode option and post again in a second, though.

Edit: I'm in safe mode right now, and it's running much better. The CPU is down to 10% and started much faster.

Does anyone else have any suggestions for how to fix this? I haven't been able to come to a solution yet. I've tried testing my memory, uninstalling some windows updates that have happened around the time it started to act up, and re-installing some drivers, but no result.

I ran the tool, but it changes sometimes. The last time I ran it the programs were taskeng.exe that had sub programs of VAIO Updt.exe and VCsystray.exe, and then wuaclt.

Sonys had some Roxio issues, also Sony installs their entertainment services.

Go to your search and type msconfig

go to the start up tab and disable everything except your antivirus, now go to your services tab, click the check box that says hide all microsoft services. Now disable everything that is not your antivirus.

Try that

It still runs up to 100%, but its faster. So, it also runs down from 100% more, but it goes down to about 40% instead. Any help with this?

Go to your power options in the control panel, change the setting to high performance.

Can you run a Check Disk. Right click your C drive and select properties, click on tools, click on check now. Select both boxes and click start. Schedule the disk check and reboot

I ran the checkdisk, it took a little while but it didn't show many results. It still stays at 100% for awhile, but now it drops down a little faster.

Still, There is no reason that a dual core machine should max out both cores at idle. So keep watching your svchost files with that app I showed you. Make sure that you find the file that is maxing out your CPU.

You may want to scan for rootkit activity, it's a quick check, just to be sure.

Also, scan your computer with superantispyware and a good antivirus. Here is a good scanner, It just scans your system, it's not a full Antivirus.

Go through your installed programs and uninstall anything that you do not use. I have a feeling that you have some how screwed something up in the registry. I hate registry cleaners, there is no reason to use them. And sometimes they create situations that are unrecoverable.

I had a problem like this on a Dell Studio that I was working on, It turned out to be an MBR issue with the drive. After I wrote in a new Master Boot Record the slowness and High CPU usage went away.

You can try that. Tap the F8 key when booting the computer. Select Repair you computer. Now open a command prompt CMD.

Type

bootrec /fixmbr

bootrec /fixboot

chkdsk C: /r

chkdsk D: /r

exit

Now reboot

Just a thought,

Some Sony C Series Laptops had faulty fans. Is your fan spinning? is your fan dusty? What is the model number of your computer?

I ran the bootrec and all of that before, and it didn't seem to work. On the issue of my fan, it's running fine. My model is vgn-fw390, and I actually just cleaned it recently. The issue wasn't a gradual thing, either. It happed a little while ago now, just kind of out of nowhere.

You could try to do a windows system restore back to before you ran that registry cleaner.
