Solution


I experienced this. Exactly like this. Phenom II x2 555 could be unlocked easily, but after some clean up and case fan upgrade, it could not post unless I press the reset button. Apparently I stupidly plugged the fan leads into the CPU socket from the PSU. I guess this has damaged the CPU rails from the PSU because even after I unplugged the fan, this symptom continued.

I fixed it by replacing the power supply with a stronger one, a Seasonic X650. Now it boots readily into X4 B55, overclocked to 3.3 GHz. Could be higher, but for now I don't need to. So, the solution is perhaps replace your PSU with a better one.

When you say " i have to press the reset button to make my pc boot with no problem." do you mean that the PC will boot to Windows & when you look at task manager or CPU-Z you see all 4 cores active?
If yes, have you tested the stability of the unlock with prime95 or Intel burn test?

It is rather strange. I unlocked 3x AMD X3 processors but never encountered this. Did this only happen when you unlocked your processor?
Prior to unlocking does it turn on the normal way via the power button?

yap it only acts that way with the 4rt core unlocked! but once in windows theres no problem! could it be my mobo? my mobo supports up to 95w cpu. my unlocked phenom is 120w. do you think that makes the issue? my system never gets hot, it idles 37 unlocked and 27 stock. with a deepcool cooler. and a TT v3 case complete with fans

I had a similar problem like this unplug all your usb's and see if it will boot. If it doesn't then you have another issue. If it boots then you had what I had some usb devices can cause the computer to not boot properly it turned out that my wifi card would caused computer to not boot. Hilarious right? I basically took my whole computer apart trying to find this rogue restart and shutdown thing.
