Quad Core Only Running 1 Core
Aug 25, 2008
My quad-core processor is only running 1 core. I have scrawled the web for fixed and such, but I'm having no luck . Here are some images from my device manager, and CPU-Z for proof, and the problem.As you can see, my device manager doesn't even show any processors, and only shows my computer as a Standard PC. And on the CPU-Z, at the bottom, it only shows that i'm running 1 core! (Also the same on task manager) All chipset drivers etc were installed.I've tried a few things, optimizing my bios and such, but im abit of a novice when it comes to the bios.

Quad Core: When I install XP I try to hear music but sometimes the music freeze for about 0,5s and after that it continue. with video its the same. I don't know why, so I try it with Triple Core... No change same like before but when i try it with Dual-Core it was OK. I install all drivers. I try old drivers, new drivers, beta drivers, new bios etc... bud i think it is in CPU, because on Dual-Core it was fine... Please tell me solution. I don't have any idea to correct this problem. TY.

I've heard that dual core can handle two threads at the same time, but has less Mhz than single core. Anybody could tell me if it is a good choice to buy a dual core processor if there aren't enough applications with more than one thread?

Due to a corrupt system file I did a repair using Recovery console. PC came back up with a few problems. Uninstalled most applications and Service Pack 2 and reinstalled. I have now noticed that my Athlon XP2 dual core processor is only running as one processor. In device manager it shows both processors and when the PC boots up it recognises that its a dual core processor. Yet when I run the Athlon utility that reports back processor information it only shows the one processor. Tried uninstalling the processors through device manager but nothing happens.Does anybody have any ideas how to fix this before I do a reinstall of windows?

I noticed that my CPU Usage History under the performance tab on my task manager shows only 1 graph. I am sure that there should be 2 graphs there since I have a E6600 Intel Core 2 Duo processor and I can still remember that when I installed my Windows Xp for the 1st time, I have 2 set of graphs for each core of my Core 2 Duo. I feel that there's something wrong... Is my active core only 1 instead of 2? Is there something wrong with my Hardware? My OS? how can I resolve this? right now Im running windows Xp SP 3,.

I am looking to buy a core i3 processor but i've heard that it does not support windows xp. Now i've searched the internet only to get more confused. Some say it works fine while others say it does work but pretty slow. The problem is i can live without i3 but not xp as i work on Oracle that doesn't support windows 7 or vista.

I just finally went from core temp 0.94 to 0.95 and I seem to have found a nasty little bug in 0.95. I keep getting BSOD when I start 0.95. Thats kinda messed up to me as 0.94 worked like a charm. I have played with it a little and I know it isn't my system.I keep getting error code c000021a.

I recently built my new dual core PC and I have set up my bios, etc. I'm ready to install an OS. What I'm wondering is - what is better for a dual core pc? XP Pro or XP Home and why?

One question about Multi-Core and Mulit-Processor machines. It is the duty of the operating system to make use of all the cores and CPUs? or it is the duty of the running application? And which one should optimize this task?

my system (2.8GHz Pentium D Dual Core, 1 GB RAM, Dell XPS 400) just started getting stuck at 100% CPU load at all times. Also, task manager only shows one CPU graph instead of the usual split screen graphs shown since its a dual core system. This occured on a restart after I re-located the machine to another house. I thought maybe something was physically messed up since it had been moved but the problem doesn't seem to occur when I boot to Safe Mode. So, that makes me think its a software issue.

I didn't even think of it when I ordered my new system. I currently have the same copy of windows xp home I've had all along. Do I need to get 64 bit XP professional for my Athlon 64 X2 dual core processor to work? I'd hate to have to have to buy a retail copy

I have a Compaq Duo Core notebook, with 1GB ram and 100 GB HD. Running Win XP SP2. I have a lot of programs on the system and over the last week or so, I've noticed that the computer is very slow.I use a program called Cleanse Uninstaller which has a junk file finder. I've used it to "analyse" what could be taken off and it presented me with a list of over 200 files. But which ones can I actually remove?? Furthermore, will this actually have a beneficial effect on the speed?Also, I have Norton ghost 12.0. and an external drive of 120 Gb. I've been doing incremental backups of "my computer" and certain essential files. Everything appears to be working okay.

Intel DQ963FX motherboard and mated it with a Intel E2200 Dual core processor. I have 3 gig memory and a NVidia 9400 GT graphics card w/1 gig memory. The machine is not used for gaming but for everyday on line tasks. The on board graphics are disabled. I updated the Bios to the latest version and am running XP Pro SP3. I have the usual antivirus protection enabled, Purchased Zone internet suite, Nortons (kept disabled in case zone craps out)and malware bytes, Super anti malware, Spybot S&D and ad aware.Sometimes when I start this machine and go to Firefox,(or IE for that matter) the system will slow to the point that even audio is stunted. I have the latest java enabled so I don't think that is the problem. This motherboard has very little in the bios to tweak so that hasn't been tampered with too much (latest bios update was installed after the slow started). Whenever the slow down occurs if I restart the machine it will run up to speed for awhile then eventually slow down again. My old P-4 3.02 was sooo much faster that I regret ever having built this new clunker. . Is there a known problem with this mb or proc that I haven't found yet?

Hello, I have not had use of my main computer for about two weeks. I would preface this with the fact I am not proficient with computers as so many programs assume one is and I am 76 years old, a retired educator with advanced work, but at this point I am exasperated to say the least.
I had my computer on working when suddenly things went sorta crazy giving me the impression what I was attempting to get off my computer was an invasion of hard core porn, a virus, and a security program I had never heard of. My screen went black and could not be rebooted at all. I came to this spot, got a little advice, but it did not solve my problem. I found a program I thought would help, paid for the extras, but found it was not as indicated. It said it had help 24/7 (not) and expects one to know computers to use it. It says they have a "WE fix it for you" portion. How that works I have not figured out yet. The phone numbers given are not for service but are for some group this program is published thru I think. After a lot of By guess and By gosh I did manage to get to a home page that showed icons that gave me the interpretation of their pictures and names were as I suspected exactly. I finally got the program for security to desist. The screen disappeared to precipitate my efforts to use the PowerSuite 2010 (their help is by internet), CA Suite 2008 which I had paid to update to current time, My XP disc that wanted to doubt I owned and requested I put Windows 98 in to prove it and then it was on a merry-go-round asking me to insert the previous disc in whichever one it was. It has said XP was not right I am sure because the computer came with Windows XP Media which I had updated

I am building a new system soon and need advice on which version of XP I should use. My system will use an AM2 processor athlon64 and an Asus M2N-E motherboard. However in the future I may get a dual core CPU. Does Media Centre Edition support dual core?Is it worth running 64bit XP?Are there any differences in performance between the different versions?

I have Win XP Home Edition, my computer crashed last night and I had to re-install windows. I've been installing all my window updates but I keep getting an error for Service Pack 1. "The core system file (kernel) used to this computer is not a Microsoft Windows file." And Service Pack 2 has been trying to download to my D drive, which is an external hard drive.

I need to have a scheduled script running at certain time of the day to stop an application (File Maker Pro) from running; the backup the database and launch the application again. I know basics of command line scripting to re launch and do the copy of the data base. The only problem is to stop the application without damaging the database
