Computer Random Crashes with no event log's

Hey All,

My issue is I just finishing putting my computer back together after having an Issue with one of my video cards,

Sabertooth P67 Rev b motherboard
I7 - 2600k @ 3.4
Msi Twin Frozr III 660ti GFX card
1x 250gb SSD
2x 2tb HHD
2x 1tb HHD

just reinstalled windows on my SDD, it runs fine, but randomly crashes
I installed Core Temp to see if maybe the new CPU fan I got isnt pulling it's weight, but its not the case, the cpu temp sits are about 47c - 49c which i think is fine.

by randomly I mean, I haven't Installed any games, or played any even, I watched a couple movies last night and it crashed, and today, i was installing Core Temp and it crashed during installation.

I cant seem to figure out the issue, if anyone has any suggestions i could try it would be greatly appreciated

Thanks;

thanks for the reply

1. it sits at about 48c idle, im using right now gaming/movie
and according too - Core Temp -
c0 = 53
c1 = 58 < - using about 15% capacity
c2 = 54 all of which are using about 2% capacity
c3 = 50

2. as far as I know, nothing, my OC is set to auto but im not doing anything hardcore and not sure how to set up for OC with bios, so i dont touch it haha

3. I have a Coolermaster 700watt PSU, and again according to - Core Temp - the pc is only drawing about 18w

4. I have tried reseating mem, also ran memtest86 on my ram to see if it was an issue but nothing faulted
