Thread Starter 
I've been having a problem with my computer for the past 3 days, even when i am not doing anything, no programs running or anything the both cores indicate 100% the computer gets extremly slow. I've already formated the computer and it did it again with nothing but windows installed on it.

I tought it was getting too hot or something but the temp is 47 c AVG. i ran Dell diagnostic tool and everything Passed.

Any suggestions ???

Thanks!

Use task manager to tell you which task(s) is hogging the CPU.

It sounds like you've got one or several programs (or viruses or other malware) that are using up all your computer's processor cycles.

That is the weird thing!

Task manager is not showing anything weird, svchost.exe is using the most memory with 53,164 K and still CPU is working at 100% Core 1 and Core 2 :S

That would indicate that nothing's using the CPU. Weird.

So if I'm understanding you correctly, when you go into task manager, under the "performance" tab, you see the CPU usage pegged at 100% but when you go into the "processes" tab, nothing is showing CPU activity but the System Idle process?

For instance, I attached a screenshot of my task manager. The highlighted tab - CPU - shows what percentage of the CPU each process is using. And at the bottom, it shows the percentage of the CPU that all my current programs are using (in my example, it's 6%).

I don't understand how it's possible for your total CPU usage to be maxed out but Task Manager saying nothing's using it.

Sorry i took that reading when it wasn't at 100%

Now at 98% this is what is showing

Taskmger.exe 44
sidebar.exe 37
taskeng.exe 09

You've got a virus. The first process you listed, "taskmger.exe" is a spoof name trying to imitate the legitimate Task Manager (taskmgr.exe). You'll need to run your preferred antivirus to get rid of it.

If you don't have an antivirus, you need one. One of the more popular free ones is called Avast.

Sorry for bumping an old post, but I've been having the same problem with my E1705 for awhile, 100% CPU utilization w/ fans maxing out and then the computer starts to lag, even when i type. This happens with a fresh install of windows vista, windows xp and windows 7 and there is no viruses. I've replaced my fan as well on my videocard, last time i had it apart, as it seemed that the bearings were stiff, probably from the fans being maxed out. I noticed before and still notice with the new fan that if i don't blow into the GPU vent, the fan does not spin up to its rpms as its supposed to. IT'll show fluctuating RPMS in i8kfangui but when u look at that fan, its visably not spinning until you blow on it and get it to spin on its own. This problem doesnt remedy itself unless I reboot the computer. Any ideas?

 

i had e1705/x1400.

 

Only thing I have changed is the Hard drive, it now has one i got from newegg awhile back.

When was the last time you took the comp apart for a good cleaning / dusting up? New thermal paste?

cheers ...

Here recently, as in less than two weeks, I installed a new GPU fan, and put Arctic silver 5 on both the CPU and the GPU just to make sure. I was also thinking, I did do a bios update, not too soon before all this happened, to A10. Sometimes mashing the 'apply' button a half dozen times in manual fan mode on 18kfangui finally gets the gpu fan to spin, otherwise I do have to blow on it. When i stick a tooth pick in the vent, the fan is freely spinning.

I would re-check the seating of the fan and its connectors. Is this fan OEM? Try to go back to the previous BIOS also - just for kick.

Cant believe it, as soon as i rolled back the bios to A09, problem solved. Does Dell do this to sabotage laptops so you have to buy a new one? I seen a lot of people with, what i think, is the same issue. Regardless, having a laptop that doesnt hit 70+ degrees celcius for the win! I8kfangui seems to be controlling things again as well.

Strange... I had the opposite experience. I installed Windows 7 32 bit and flashed to A10 Bios and the system works better than it ever has in the entire time that I owned it.

I forgot to mention. I had originally worked around this problem by disabling the CPU speed stepping option in the BIOS. After upgrading to A10 I was able to turn this feature on as it now works properly. I thought I had a virus as well, but apparently it was a problem with the BIOS interacting with a notoriously buggy feature of the Intel Centrino. If you don't use your laptop on battery a lot you can just keep speed stepping disabled and it will always run at the higher speed.
