Windows 7 RC1 Bug

[aftlizard]

I am wondering if anybody else is experiencing this bug.

I have a new install of RC-1 which I installed on a built from scratch system
, main components are:

Gigabyte GA-MA78GM-US2H
4 gb ddr2 667(don't need anything more powerful for it's usage)
ATI HD 3850 GPU
Phenom II X3 720
1 80GB HDD for OS and a 1.5 TB drive that hosts my video files.

Anyways to get to the point for some reason, I am not exactly sure, Windows 7 will only show and use one core of the CPU after a point. In task manager it shows only one core in cpu history and you can't change it. In device manager it shows the three cores and while CPUID reports the model properly it shows only 1 core is operating in the lower right hand corner.

I am not sure what exactly is causing this. I use the system as an HTPC and occasionally the video will bog down. The files are all divx,xvid and vob and shouldn't bod down this pc or any others made in the last 5 or 6 years. After I noticed this last bog down that is when I checked the cores and it showed only one being used. Now before I started to play that video I had woke it up from sleep, which potentially could be another source of the problem(Windows 7 not reloading properly). On reboot everything goes back to normal.

many are having problems with sleep resume but i dont use it so havnt any exp with that, the core issue could be a bios update issue

I'm not having problems with sleep resume and I use it several times a day to power down the system when not in use. The system wakes without an issue. I also am not seeing any issues with multi=core processors.

Well S3 sleep resume seems to work great, better than any other MS OS so far(well faster anyways). Maybe it could be the bios, I do have the latest though from GIGABYTE. The issue showed up to me again. Same thing while playing a divx movie. However something I noticed last time but didn't think of mentioning and that is Coo N Quiet appears to be disabled when playing. I tend to check things like this while I have a new system running and even while multi-tasking,(ie; 7MC in a window, cruising the net with about 7 open tabs,) the new PII rarely goes above 1.1 volts and 800 Mhz. In fact the only time it has gone higher than 800, other than when it "breaks", is when I am converting file formats or playing BD or HD DVD's. I am going to try rolling back the BIOS and if that doesn't help then I will consider changing the mobo or cpu AND if those don't help then I bet it's the OS. I remember XP had an with the first dual cores that was simila but there isn't the same fix available in msconfig like there was before.
