My pc when I press start button starts for 1 or 2 seconds then turns off and boots normally, is this a problem?

No my friend is not the reboot button for sure, it is like when you overcolck your PC and it turns off and then turns on again.

I have them both at auto with ASUS standards not Intel's standards and i have enabled the system economy ckecked how is lowering a litle the cores voltages e.g. at my primary core enabled @3.8GHz 1.245v and disabled this 1.267v
But now i see at the HWinfo32 since I open X.M.P 2.0 this choise not works and i uncheck it as ASUS says "for all kind of overclock have disabled this choise"
I have my primary core to 3.8GHz and the other 5 at 3.6GHz
If you please take a look at these two photos I show you the voltages

One other who i must tell you is my CPU is don't gives me the results who is writen at sites like Anandtech e.g. there at Cinebench 10 is writen single thread result 7400+ i have allmost the same 7200 to 7300 but at multicore result is writen 40000+ and i have 38000+ my result, at Cinebench 15 multicore is writen 1132 and my result starts when i buy the CPU from 1098 one time, but the stantard was 1082 who i take everytime and now after 4 months and many games and programs who i install and the new BIOS from 3501 to 3504 version i have result 1075.
The new bios is the only ASUS bios for this mobo who says Improve System Performance I don't see it at my pc but the opposite. All the others say improve stability. I flash again the old BIOS but the results stays at lower than before so I flash again and now i have the new BIOS. Besides Asus Rampage V Extreme\3.1,my motherboard has extra pins for better performance, I don't see that in action...
That is weird and i don't know why is happening, I ask the retail shop and the answer was "this is results of a bench table not a PC full of programs" I agree.... but my previous CPU I7 950 @ 3.06 it performs as the anandtech says even with programs the first two years eg if i remember well it performs at cinebench 10 18000+ and i have the same result for the first two years because O.C. who I make is lowered the CPU power and it was normal after years.
In windows i don't use the max power power plan but the balance with some changes like the PCI , the HDD and some others just to keep my cores at low voltage when idling because at max power plan they always all cores stuck in the maximum voltage even if i change the processors use at this plan.

P.S. When i make benchmarks i always use the maximum power plan
