Possible HW failure?

Hi. My laptop CPU (4700MQ) is presently exposing these signs:
1) noticeably lower Passmark performance index compared to others of same model
2) unlike before, CPU no more reports support for VT-x, independently measured with CpuZ, Intel CPU Identification Utility and Aida64. There might be more extensions no more supported, for complete list of currently reported extensions look here: http://content.screencast.com/users...7fc2-488e-8617-68ce08a62f51/12.15.2013-21.png
3) unlike before Intel Processor Diagnostic Tool (IPDT64) no more is able to finish (stalled permanently on Waiting for cache size stage)
The question is if one or more of these signs indicate possible CPU deffect ?

I have made scan yesterday (SuperAntiSpyware + ADW Cleaner).
I assume the PC is clean and I also think that procesor extensions shouldnot be turnable off by any malware.
Performance shouldnot be degraded by any unwanted process (CPU utilization in idle state is no more than 10%, mostly utilized by Firefox and audio player)
As for temps, these look quite in normal I think. Here's a complete sensors report by Aida:

This is first thing I made and BIOS is most recent (1.30)

Thanks for the replies, but these still don't dispel my doubt about my CPU malfunction. For making sure, I reapplied latest BIOS updater from my Laptop vendor. It told me that it won't update because latest BIOS version is already onboard. I check also that VT-x is enabled in BIOS, look screens, then restart and VT-x is still not detected under Windows.
Second thing is why Intel Processor diagnosis never able to finish now... May these thing be related?

you have hyperV installed on windows? when you install it the vt-x is no longer shown for the processor. it's window's way of making sure they dont have to compete for the feature with other virtualization software. so for example if you install hyperv and ... virtual box only one can use vt-x. since hyperv is a microsoft tech it gets priority for it.

AFAIK there's only Disabled and this. There may be (guessingly) also VT-x and VT-d choice for CPUs that support it.


That may be it, where do I turn HyperV off?
Also may be this the reason why IPDT64 now freezes during diagnosis? (IPDT output)

Yes disabling Hyper-V seems to unblock IPDT and reenable VT-x reporting. Thanks so much. Now should I prefer Hyper-V or pure VT-x when I want mostly use virtualization in VirtualBox?
Yet there's the low performance question unresolved. Could i get some recommendation about CPU benchmarking alternate to Passmark PT?
 
hyper v is microsoft's virtual box. if you want to use virtual box there's no reason to keep them both and as explained hyperv would remove vtx from virtual box (without vt x the virtual box has some limitations - 4gb ram i think and 1 cpu core only). under windows 2012/win8 hyper v should perform better than virtual box. (although if your vm's are already made i dont know if you can switch).

you could try the synthetics tests from here:
