X2 Wierdness.. one core runs at load even when idle?


Recommended Posts

right.. i've run a program called sysinternals process explorer and something is definately up.

 

Athough task manager shows system idle is at 99%, this program shows it to be at around 60% with the rest taken up with hardware interrupts and Deferred Procedure calls.

 

So it looks like a hardware conflicting issue no?

 

Neither of these 'processes' can be stopped, changed or suspended as technically, they don't exist... they have a n/a for the PID.

 

I'm not sure what could be causing it...

 

I guess i'm going to have to pull out every add-on card and device I have to check.

 

is this a known problem?

 

It sounds like a hardware conflict to me.

 

I would suggest removing all non-essenatial hardware from your computer. IE: sound card, usb devices, cd-rom, etc. If the problem disapears, put one each peice of hardware back in one a time to see if you can find the curprit device. Once you have, try to find newer drivers or firmware for that device.

Take out the Audigy card, in my current build I had to remove it because my computer had weird crashes, etc., which all ceased upon removal of the Audigy card. I had the card in the next to the bottom slot, rather than the bottom slot that many here recommend, so maybe that's it. When I have time I'm going to get that baby to work, but I'd had enough problems for a while. ;)

Yeah... my initial suspicions pointed to the Audigy card too, so your post kind of strengthens my general theory.

 

maybe the audigy is conflicting with the onboard sound? I have them both installed and enabled, so I guess the first thing I should do is disable the onboard sound in the bios.

I have seen Hardware interrups problems like that one for devices like infrared ports etc.

 

disable your ports in the bios,com, ltp.

 

sometimes if you have a printer problem system take 40 to 100% a esy test is to stop the printer spooler service.

I have exactly the same problem! Didn´t see it before until U told about it... :( I´ll try to find what is causing it, if i discover something i will tell U.

 

Anyone else? All you X2-processor users!!!

Just out of curiosity do you have your Affinities set for certain apps. If you have a crapload of background processes running on different cores. That can and will cause CPU fluxuations in usage. That was the only way I was able to simulate the issue. After all were done I was idle like normal. What revision of proc do you have? I would try it in another comp to be sure. You may have a bad proc.

hmmm... XT2.5, you know what? we are running the exact same Graphics cards Club3D 7800Gts.... maybe that could be a cause???

 

could just be a coincidence though?

 

but like I said, I can't know for sure until my system actually decides to boot.
