Hey guys, new person here.
Always lurking...but first time posting....and im afraid it's not good news
Monday morning of this week i got an HIS HD 6850 in my machine, and for the entire day it was flawless. Played EVERYTHING at full spec beautifully [NB, my monitor max res is 1440x900, also, im upgrading from an 8500GT]
Wednesday evening however...while playing Crysis, my PC just shut off OUT OF THE BLUE. This never happened before.
It's like electricity completely left the machine. It wouldn't power up when i pushed the power button, I had to plug the power out, flick the switch off and back on, plug it back in and then power would come on...Then it didn't happen again.....so i didn't really sweat it...
Until the day after...Yesterday...i was playing Borderlands....and it randomly shut off again....so i had to do the same unplug switchy thingy to get it back on...and since then the PC doesn't necessarily need to be playing a game to randomly shut off...
i could just be messing around online, listening to music. Once or Twice it even shut off while it was booting up
Since then I've been doing everything i possibly can to try and see what the problem
I disconnected all case fans, case lighting, optical drive from the PSU etc [everything that isn't required for the PC to boot], just to see if the PSU wasn't providing enough power [doubt it though....it's a corsair tx650]
...no dice
My mobo downclocks my RAM to 1333, so earlier this year i just bumped them up to their 1600 ratings.
i downclocked them back
...no dice
Switched the RAM between the slots...tried 1 stick each...
....no dice
I switched the graphics card to the other PCI-E slot
....no dice
i disconnected the extra hard drive....no dice
I did some detective work....ran Crysis, and on another occasion COD-MW2, in windowed mode to watch my cpu + gpu temps while gaming, till the pc shut off again.
cpu never went past 47C, the gpu [when it was under user defined automatic fan control] never passed 66C.....while under factory automatic fan control went up to 77C, although i read that they go up to 80's with no issue....so i'm pretty sure it's not heat...
the only thing i haven't checked is the MOBO temps...but the PC is up in BIOS now (been on for about an hour now, no shutdowns so far *fingers crossed*), and im watching the CPU and MB temps and its nothing to make a note about
I know some of the things i tried might have been pointless, i'm not THAT knowledgeable with PC's....I'm just really worried and i really need to get to the bottom of this...
some help would be greatly appreciated guys
