HELPL overclocked i5 reboot

[XdVeLoPeX]

I dont know why but while running LinX after a few pass's the PC shuts off doesnt restart until I hit the switch... no bsod errors nothin...

Sounds like an unstable overclock. Back it down or maybe try a little more voltage.

it ran fine last night for two hours or so with 200x21 = 4.2ghz @ 1.28125 in BIOS
when i woke up the pc was still on saying failure with IBT now today I try benching it and it shuts down no warnings no notices nothing and doesnt turn itself back on until I do..
then turns on normally ... so I upped the voltage in bios to 1.33750 and also upped the IMC voltage from 1.2 to 1.3 now... same shit... no errors turns off. im on h50 and temps never over 80 under 100% load... so I go hmm changed only my multiplyer from 21 down to 15 for 3ghz and bam... im typing this message while ibt is on like pass 100... wierD?

Those specs are nice, but have you narrowed down the potential problem area(s)?

I am still not sure... Didnt crash @ stock speed and didnt crash at 4.1 but does above it..

Ok so I am very confused here.. what causes a system to SHUT DOWN no warnings.. BSOD's... nothing. I had it running for hours a 500 pass IBT @ Standard it passed it.....

Then I click on "OK" after it telling me the system is stable changed the run time from 500 up to 1000 tests and hit "START" and what do you kno.. SHUT DOWN.... *** MAN!?
