New Board+New CPU=Problems!

[DJ Trance AZ]

Not sure if this is the right place to start...

About a week ago, I have put together a new system:

DFI LanParty UT nF3 with Athlon64 3200+ with 2 sticks of regular DDR400 256mb RAM; the rest of the components are stuff from my P4 2.8 machine; hooked up using a Vantec 350w PSU.

---------Normal------------
So OK, the system has been up and running XP SP2 no problem 24/7 for about one week, with intense gaming and application usage, no single crash whatsoever. CPU temperature is around 50 degree C @ max load, no overclocking done, everything @ stock.

----------Abnormal---------
Last night I decided to restart Windows, so I did....After I did that, weird things started to happen-STOP error in the middle of loading XP. So I turned off the PC and started again in 1 minute, same thing happened, I pushed the RESET button, this time, it's even more weird-the computer itself KEEP ON RESETTING itself (I can see that my optical drive's lights keep on flashing and flashing).......I turned off again, this time trying to get into safe mode, can't load it and STOP occur.

---------Interventions---------
So what I did was put in new power supply and new set of RAM. Reformatted the HD and reinstalled WinXP. Installation went smoothly...got into windows...After another restart, the STOP error came back (Machine_Check_Exception).

I now notice that I don't get STOP error when loading XP....now I mainly get the STOP error when XP desktop is loaded...

---------No idea---------------
This is definitely not fun @ all...Do you think I have a bad board or bad CPU? Or something else?? I am really hoping you guys can share some ideas with me!!

Thanks for reading my stuff, and am looking forward to see your replies!

Side note: Sometimes I can load XP no problem without the STOP error, so I can surf and do stuff like normal. So last night, I ran Prime95 torture test until this morning! Guess what, it DIDN"T encounter any problem!!! NONE...the test just kept on going...

Are you using dual-channel configuration? Try disabling it if you are, because it could the memory controller on the mobo having issues. Most BSODs and Stop errors are caused by RAM or mobos, and if you've tried different RAM then it could well be the mobo.

The board is not dual-channel capable. I swapped out the RAM and put in some new ones...still no go man....

What's the chance to have a bad CPU?

Thanks for your help!
