Windows 7 Kernel-power, Event id: 41 windows 7 64-bit (again!)

[indarkness]

Hello dudes!

I have got trouble my my Alienware Aurora, all start with BSODs(produced by the graphic card) and after calling the technical support they changed it. But then, the pc started to reboot randomly which happens currently.

The problem is that there is not a BSOD associated to this crash, neither a minidump file or in the LiveKernelReports folder. So this way I cannot explain the issue to technical support in an "technical way". This crash only appear in the windows event viewer being the following:

I have restored windows 7 twice, the preinstalled partition that the computer brought from Dell the second time was last Wednesday(December 2011 7[SUP]th[/SUP]) ,updated the BIOS and the drivers but I cannot fix the problem. I have been reading about this same problem in this forum as well as others, but almost all the solutions given I have already tried without solving the issue( such as changing to high performance,reseating the RAM sticks,disabling AMD HDMI output...). I have read the MSDN for this topic ( Windows Kernel event ID 41 error in Windows 7 or in Windows Server 2008 R2: ), being useless in order to figure out what’s happening...

I have noticed also that when this error happens, in windows system propierties appears 3GB(1.99GB availaible) and using the resource monitor there is 1GB reserved for hardware.

Thanks in advance!!!
