PC Wont Shut Down Completely When Overclocked

[yabyyoyoboy]

hey Everyone,
I have a question? Ive been overclocking for a while but never seemed to figure out what this problem is. well i have a LGA775 Pentium Dual Core e5400 2.7GHZ thats been overclocked to 3.6ghz . today I tried to push it even further and managed to get upto 3.8ghz with this cpu and stress tested it with no problems. After a bit of searching i restarted the pc but as soon as it goes past 'shutting down' scrren the pc hangs right there and will not boot back up. the only way was to hard reset and eventually it loaded up fine again. i reinstalled windows thinking it was the problem but that didnt fix it. after putting the overclock back to default it restarts and boots fine. please Someone help me. Much will be appreciated

My specs:
intel Pentium Dual Core 2.7@3.6
4GB DDR2 800@890
GTX560
1TB HDD
G41M-Combo
Coolerpower 550watt Power supply

Oh And another thing when I overclock my voltage is very weird. i had to set the vcore to 1.45v to get it stable but when i check in cpu-z it says only 3.9v is that normal or is it a problem?

raise voltages a little? it sounds like its not stable.
you can aldo get ccleaner to fix your registry from shutting down incorrectly

hi, I have increased the voltage but still the problem persists. its is a 1005 stable as i have tested it with prime 95. i dont think its windows as i have already remformated to drive and clean installed window 7

seem the ram not strong and unstable , rise vdimm max at 2v ... also drop ratio ram 1:1

overclock use mobo G41 is hard .. find in bios seeting memory drop FSB / ratio RAM according option your mobo ..or Drop your OC .. if you had more time ran memtest overnight
