My CPU has been touching 100% a lot, the only reason I noticed this was because my MP3 tracks were skipping, and this we cannot have.vi

After 2 virus scans, CCcleaner, Spybot and Adaware finding nothing, I have found that pausing my BT downloads fixes my MP3 problem and my CPU gets a rest.

I have never experienced this before, can anyone explain it or is it pretty normal. Bearing in mind its a brand new computer with plenty of RAM.

5 word summary: Downloads fucking computer, please help.

Much love.

Does it have vista on it? Vista often shows 100%, the first few weeks you have vista, it works a lot harder as it finds out what you commonly uses your pc for. You could right click and change the priority of your mp3's to high, to give it system preference over torrents.

It is Vista, where do I right click?

Download and run this..

It's a far more in depth alternative to the task manager, you should be able to diagnose the app that's taking up all the CPU and kill it.

What app are you using for torrents? I recommend uTorrent as it's really (really) lightweight.

It's uTorrent I use. Hardly takes up any resources at all.

utorrent is fantastic.

Strange thing is, I am using uTorrent and I've never had any problems like this before.

Cheers for that Ric, I'll have a good go at it when I've not been drinking.

Problem update.

My computer is getting boxed by Download Accellerator Plus. Won't even play a VLC video. It seems that any severe internet usage ruins anything I'm trying to do.

What can I do? Is this a network card issue? CPU issue? DAP has never caused me problems before and neither has Utorrent, but this is definately the case.

Uninstall DAP then? Does it actually make a difference to your downloads anyway?

All DAP does is fire multiple connection requests to the file, all async, which in theory speeds up the download in question, but due to the scattergun approach it takes, it saps what bandwidth you have. I've found DAP to be a little quicker than the normal download manager, but not by much.

DAP shouldn't be the reason your entire 'net connection is slowing down though. That sounds like bad drivers, poor connection at the exchange or (the dreaded) virus/trojan using your machine as part of a botnet. There are several ways to diagnose what is going on, but first things first is running a decent and up to date virus scan then run the spybot/adaware to remove anything left over.

I've done numerous virus scans and use spybot and adaware regularly to no avail. Uninstalling DAP isn't really the issue, as I have the same problem with Utorrent, or any kind of high download totally boxes my CPU, youtube videos, BBC videos mp3s and VLC files are really jumpy to the point where I just can't have them running concurrently. Closing running programs that aren't needed makes no difference.

I'm at a loss as my drivers are all showing as up to date, and it's a brand new computer so this shouldn't really be happening.

Have you spoken to your ISP?

Would their service really affect my laptop's processing?

Did you download the tool that Ric suggested? That will help isolate the problem.

Yeah but embarrassingly I don't understand it, everything moves about constantly and it confuses me.

Never used it before, but looks like the two columns on the right are processor and memory usage. Sort by each of those and see if anything is using a lot more CPU or memory than everything else.

Or, post a screenshot on here and Im sure someone will be able to decipher it

I'm running a virus scan at the moment so i'll post a screenshot tomorrow when I'm having this problem and one of you handsome gents can help me out.

Much love.

Gents.

Here is a picture of my process explorer while the MP3 is skipping something horrendous.

It appears that DPC is taking up most of my resources, but I neither know what this is nor understand what I can do about it.

Hand jobs for anyone who helps.

DPC or Deferred Procedure Call basically shuns low priority programs from the CPU when something of higher importance requires the undivided attention of the CPU.

So you'll be pleased to know it's not a virus. Has this problem always occured on this PC, if not, did you install any hardware or software immediately before this started happening?

As the only process eating CPU time is DPC and there is no software showing an unusually high CPU time, we can pretty much remove applications from being the culprit as well.

My guess is a device driver is being a little over active on it's IRQ's and since pausing your torrent client fixes the issue I'm going to have a stab in the dark at either your Wi-Fi driver or your ethernet driver are being a bit naughty. When you experience the problem are you wirelessly connected or wired to your router? Whichever it is (or both - who knows...) I suggest updating the corresponding driver in Device Manager.

Its a wireless connection. I turned it off at the switch, and my CPU dropped significantly although there was a slight skip. However, I tried to update my driver and its the most up to date one.

I've had to reboot after msn crashed, and now it seems to be working fine with uTorrent going rapid at 760 kb/s along with winamp and firefox running, so I have not got the foggiest what is happening.

It certainly seems to be an issue with the wireless card, so for your prize, see Mr G Thomson.

I'll pass if that's all the same to you.
