System keeps failing

[ninjakarlsej]

Hi all!

My PC has been very weird, yesterday I tried tweaking the case fans in the BIOS. My pc then started turning off randomly, no warning text or anything, just bam, off. One of the times where i restarted my pc i got the message "overclocking failed! Press f1 to Enter setup" (or something like that). I havent done any overclocking because im too scared of doing it. I tried running an Aida64 test but when it got around to testing my CPU it bluescreended with the message (KERNEL_SECURITY_FAILURE). Ive never had problems with this and my pc has been running fine for like 3 years so Im really scared that I've done something i shouldnt have.

Specs listed down below, please help!

Motherboard: ASUS Z87-K
CPU: i5-4670K 3.4 GHZ (cooled with a watercooler)
GPU: EVGA GTX 780 SUPERCLOCKED w/ ACX cooler
PSU: CoolerMaster GX 650W bronze
RAM: G.Skill Ripjaws Gaming 2133 MHz 2x4 GB

May try those in the link. http://www.reviversoft.com/blog/2013/06/kernel-security-check-failure/ If you run the RAM at 2133mhz, you do oc the RAM.

ooooh ok thanks alot! It hasnt turned off by itself for quite some time now so i think i might be fine. I think the reason was that in the BIOS i had it on "ASUS optimal", i found out that it auto OC's something. Ihave it on normal now and nothing has gone wrong since that.
