Computer stopped working, help please!!!

post #1 of 6
Thread Starter 
my build has an i5-2500k and a gigabyte z68x-ud3h-b3 motherboard. i've been trying out different vcore settings for a stable 4.5 overclock and last night i turned off multi-step line load calibration and set the vcore to 1.33. my computer restarted but now won't stay on. it powers up and shows the bios screen but then the computer loses power and restarts everytime. i already tried resetting the cmos. the only other changes i made prior to my problems was setting the ram voltage to 1.5 and 1600 speed. do i have a major problem?

Did you tried a hard cmos reset? Removing the cmos battery will put all settings to default. 1.33v is still far within limits and should not cause any type of permanent damage.

On those motherboards have a look for a MemOK button, if you don't have that then you will need to use the jumper to flash the CMOS back to stock, i've found that taking the battery out doens't always work.

Nope I doubt it, it's just gone into one of those 'funny' boot loops, clearing the CMOS should fix that.

Eventually when you do get into the BIOS make sure you set the RAM to stock, either via XMP or by manually setting the RAM voltage and timings. If I remember correctly Level 5/6 Multi Step LLC works best when using manual voltage on the gigabyte mobo's. LLC control will help the vdrop under load. Vdroop is the cpu voltage under, it's the difference between what the vcore you set in the BIOS to what you actually get in Windows.

Hope that helps.

i manually set the ram voltage to 1.5 and the speed to 1600. ill set it back to stock whenever my board decides to stop looping.
