Odd Problem - CPU Maxing Out During Installs

post #1 of 10
Thread Starter 
I have a rather odd problem. For some reason, my CPU (e6300) is maxing out one core whenever I am installing a program from a CD or DVD. The other odd thing - the System Idle Process is using +-96% of the CPU during this time. So nothing is showing up as being a process that is using up an entire core, but something sure is.

I've heard of some wierd things that go on with the JMicron IDE controller that's on my motherboard, so that might have something to do with it (the DVD-Rom I have is IDE and is using that controller).

Also, as further proof that the core is being entirely used, the rest of windows runs VERY slowly (mouse lag, etc), and even the installs take a long time (Oblivion off of a DVD took almost an hour).

Any help is appreciated, I don't really know where to start on this one...

Tried reinstalling the drivers... no change. I was also looking for updated drivers from Foxconn, but no luck there either. Does anyone know where foxconn has driver downloads on the net?

By the way, here is a screenshot of the Task Manager proving the situation. This was a screenshot taken while I was installing Call of Duty 2 off of the 6-CD set.

System idle is supposed to "take" the rest of your resources. The CPU usage at the bottom of the pic only shows the middle value for a certain time frame (probably one sec or something)...

I understand what you're saying, but the "middle value" (CPU usage) stays at 51-52% constantly (maxing out one of the cores). It's not in the middle of going up or down.

I know that the system idle process is supposed to take the rest of my resources, my question is how can it take 96% of the resources when 50% of them are being used already? And where is that 50% being used, because it's not showing up in any of the processes in the task manager?

My best guess would just be that it just doesn't update frquently enough...I seriously doubt there's anything wrong with the windows code on your computer only But, they do update a different intervals...

The CPU usage is updating every second (default setting). And every time it updates, the total CPU-usage is around 51-52%. It stays there CONSTANTLY whenever the DVD-drive is in use. How could it not be updating frequently enough? And the per-process CPU-usage updates at the exact same time as the CPU usage total at the bottom of the task manager (open up task manager, you'll see what I mean).

So my paradox still stands. How can the CPU usage be at 52% when nothing but the System Idle process is using it? By the way, the task manager in the screenshot a few posts above is sorted by processor usage, so the highest-usage processes are shown first. The only process using a significant amount of the CPU is the task manager itself, and that's only 3%.

Can you download Process Explorer? It will give you a a better description of what is using your CPU. Task Manager doesn't display everything. I have a feeling it might be hardware interrupts that could be causing the CPU usage.

Now to revive this once-dead topic. I finally downloaded process explorer and ran it during an install of MoHA (terrible game, I know, but I wanted to see how it would perform on my relatively new system). Interesting findings - it seems as though hardware interrupts are the problem. Anyone know any reason for this, and what I can do to fix it? Thanks.

BIOS update seems to have fixed it now. foxconnchannel.com for anyone with a similar problem.
