My laptop suffers from constant CPU spikes. Even in idle state, it runs at around 40-50%. When I use a browser, it shoots up to 100%. I've tried IE, FF, Opera, K-Meleon, and the problem persists. Tried Flashblock in FF, but that doesn't seem to do change much. Disabled all add-ons in FF, but still no joy.

Ran Defrag, scanned the system with Spybot, Ad-aware, McAfee VirusScan and they haven't found anything.

Any ideas would be greatly appreciated.

System is running XP SP3. It's a Dell 620 with 1GB Ram. Centrino Duo 1.8Ghz.

try hijackthis and see what you have running on boot-up and msconfig

auto updates turned off

also have you got system restore turned on etc
#2
Have a look at the Task Manager and see what processes are running.

Could it be you have toop many secuity products running and they are all conflicting with each other.

You have listed some, but you may have Windows Defender as well.

Also, if your computer is low on memory you could be doing a lot of swapping (moving data from real memory out to disk (virtual memory) to free up real memory, then moving it back in to real memory when it needs it).

Constant swapping like this is called thrashing and if the computer is constanly swapping it often cant get any other work done.

a good start would be to use a process viewer and see whats actually running

The fact you have mcafee installed could be a big clue!

that and you are running on 1gb of Ram, I would drop Mcafee and use something less consuming like AVAST

have a look at task manager and tell us what processes are eating your CPU

Its almost certainly the 1GB ram - McAfee combo. McAfee will scan a programs binary on startup resulting in a 100% CPU use for a period of time, 1GB is scarcely enough for XP-SP3+McAfee so you will be doing a lot of paging. You've probably also got lots of background apps each using a small amount of CPU and not-insignificant amount of RAM which will hurt when you only have 1GB to play with.

Thanks for the responses. I got it wrong about the McAfee. I actually have CA's eTrust running on the machine. Checked all the processes and nothing is out of the ordinary. At one point, PointSec was running, which was caning it. I disabled it. It seemed fine for a few hours, but then went back to its old ways.

Yes, system restore is turned on. No, Windows Defender isn't running.

Is there any way to find out if swapping is taking place?

Whats your memory usage on task manager? That will give you an idea...

When I'm running it idle, it's usually Explorer that eats the CPU. When I run a browser, it takes over the CPU hogging. At times, svchost tanks it.
#11
the page file graph under performance on task manager. if it is peaking a lot then you're thrashing the swap file and need to upgrade your ram

It's between 400 to 500 MB.

i've tried a few different things and i can't get my svchost to hit close to that kind of cpu usage, mine flits between 0 and 1%

are you using a USB modem of some kind? or umm, I don't know. have you tried running malware bytes, or some others in case you have a trojan hiding somewhere.

if you're connected to a router via wired or wireless networking try updating the drivers.

scvhost can sometimes be replicated into several process all genuine, but occasionally it your getting some major usage like this case it may be something dodgy. I would reconmend a scan using Malware bytes, and dropping Mcafee and doing a full boot scan with avast

install PROCESS EXPLORER and check what svchost.exe is doing as you may have some windows function starting up and consuming your cpu which you can disable.

Process Explorer v11.33


All Versions of Windows
Microsoft Sysinternals has a great free utility called Process Explorer that is like a task manager on steroids. It works on all versions of Windows and allows you to easily see services running inside of svchost.exe. Download Process Explorer here. Once you have it running right click on any process and select Properties. Then click on the Services tab and you will see all processes running inside the host process.

Thank you all. Will try your suggestions and post the findings.

Update:
Ran Malware bytes and it found around 25 items, which it removed. The system seemed fine after that for a few hours, but then the dreaded spikes started happening again.

Downloaded Process Explorer and found that the DPCs (deferred procedure calls) were taking up at least 30% of the CPU. Running DPC Latency Checker to see what's causing it.

now, we're getting somewhere :thumbsup:

I had this problem a few weeks ago, turned out it was a badly seated graphics card. Try reseating all cards.

OOps just realised you have a laptop. The same thing applies though, DPC issues are usually hardware related. Could be driver related too, have you updated any lately? Run updates on them all anyway.
