Hello,

sorry for the late reply and thanks for replying!

I installed a windows 7 home premium, the BIOS is up to date and I have tried re-installing the command center.

I have also tried a power drain but regardless I cannot seem to access the dell diagnostics.

I will give re-installing the command center a go again as I didn't remove it from my registry last time, the only worry I have is that the PCI fan is at 0RPM, ill update to see if the re-instillation of the command center makes a difference!  **update: After re-installing the command center using Revo uninstaller I restarted my pc and thereis still no difference, PCI RPM is still at 0 and my ambient sensors are still at 0 also...still confused as why I cant access Dell diagnostics? is the link to the support page a driver for the dell diag tool?

Cheers!

I just sent you a PM, after doing some digging around and installing CPUID HW monitor I think that my PCI fan is actually running but command center isn't picking it up.

Im getting different fan speeds from the HW monitor though:

Fan 1: 1200 rpm max 1216 rpm im assuming this is the system fan?

Fan 2: 3400 rpm max 3500 rpm (slightly worrying fan speeds) this is possibly the hard drive fan?

Fan 3:  1500 rpm max 1600 rpm I think this is the graphics cards fan?

Core temps from core 0 to core 3 are ranging from temps 40 to 50 with my graphics card temps ranging 40 to 60.

So I think my fans are all working however now im just worried about fan 2's speed? 3500 rpm is quite high?

Thanks for the help!
