I bought a CPU (5600+) to replace my old one (4200+) and now when I let the computer run for more then a minute after I get to windows, it reboots.

I do not think this is an overheating issue as I can let it run forever in safe mode. One peculiararity is that the computer thought the CPU fan was not running even though I could see it was when I plugged the fan into the original power slot. I solved this by plugging it into an alternate one.

First crash happened after I updated the windows 7 experience score

OS: Windowns 7 up to date
CPU: AMD 5600+
GPU: Radeon 4670
mobo: M2N68-LA
RAM: 4 gigs DDR2 G skill

You may need one or both of two updates.

Update #1 Make sure your motherboard's chipset drivers are up to date.

Update #2 You may need a BIOS chip firmware update that supports faster processors.
Make sure you have the vendor's drivers that may be associated with your processor, sometimes Microsoft's driver updates don"t always work properly.

Lastly, when windows is running in safemode there is less stress on the processor and it is less likely to over-heat (it does not have to crunch as much data), when windows runs with all drivers loaded, there is more to process, therefore, there is more of a chance it will over heat.

Make sure you put heat sink compound on the processor before you put the heat sink on it.

Also I should have posted a warning about making sure that any time you venture around inside your computers case, you ground yourself to the computers case.
The human body holds electricity powerful enough to destroy the sensitive electronic components built into a computer.

I've searched for an updated BIOS but all I can find in terms of drivers for this mobo is drivers for the video and LAN.

I'm still not sure this is an overheating issue as its rebooting rather then shutting down.

And yes I put thermal compound on when I put in the new processor.

The M2N68-LA seems to be a board made for HP.

IMO, that means that one cannot expect it to perform like a purchased motherboard....meaning that it may not support CPU upgrading.

From http://h10025.www1.hp.com/ewfrf/wc/documen...name=c00906129:

"•Supports the following processors:
◦Athlon 64 X2 with Dual Core technology up to 5600+ (up to 89 watt)
◦Athlon 64 less than 4000+
◦Sempron less than 4000+"

Yes, this is why i went with the 5600+ as it was the highest the mobo could handle. However I suspect that because this is a revised version of this cpu, sitting at 2.9 rather then the first release version which was 2.8, this mobo can not actually handle it.

One thing I have noticed is that my PC reports the CPU speed as 2.91 instead of 2.9. is this a problem?

What we need to keep in mind is that highscore stated "it will run forever in safemode"
In safemode most of the hardware drivers are not running....but the CPU is still processing.....it seems like we're looking at a driver issue here.
Just curious, have you gone to event log in administrative tools to see if there are any errors logged related to your processor?

Also is there any dump files that you can access for stop errors?
I use bluescreenview to analyze those.

I stopped by bestbuy today to ask the people at geeksquad what they thought. I was told the reinstall windows as this sounds like a driver conflict.

Any thoughts on this and the previous post?

EDIT: I've also noticed that Core temp will not work anymore. I removed it and redownloaded it and found it will run for 5 seconds and then crash saying that the driver has failed to load. So maybe this is a driver issue with the CPU

What happens when you put the 4200+ cpu back in?
Make sure your grounded to the computer's case at all times!
Does the computer now run indefinatley?

I had planned on trying this eventually but keep putting it off.

I will be sure to test that out tomorrow and let you know the results. I think this might have something to do with the mobo as the mobo can no longer thinks it can operate the cpu fan when the cpu is plugged into the original slot.

Old CPU seems to be running fine.

I'll run a few apps and report the temps, but would it appears this mobo and this CPU are most likely incompatible or that a reinstall of windows with the new CPU would fix this?

Just played some CoD on the old processor and everything ran fine.

Temps were a high of 31C and a low of 18C
