Had this graphics card for like 6 months now and this problem has always existed

basically at random times the computer will just restart (like error, screen just dies and horizontal lines kinda thing).

The computer doesn't BSOD so can't check error dumps and nothing states error occurred.

On event viewer an error shows up as critical and just says "The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly."

I've mostly noticed it (not sure if it's always during this) when playing games such as Diablo 3, WoW etc. Graphics card goes to about 70°+ and most times it occurs during that.

I've tried re-installing/updating drivers etc, any ideas?
 
Oh I thought all that info was in my sig fro mages ago, guess not :P

"|| Intel i5 2500k || Sapphire HD 6950 FleX 2GB || Corsair 650W || ASUS Sabertooth P67 R3 1155 || 8GB G-Skill DDR3 1600Mhz || OCZ Agility 3 120GB SSD || Barracuda 1TB 6GB/s || 3x BenQ G2222HDL ||"

edit; also everything is at stock.

Just got it again, only things that were open were chrome, msn, skype...

I've got the exact same opened now as temp is just under 60, GPU clock 450Mhz (set to 800Mhz when it's actually being used) and 1250Mhz memory clock.

Any ideas what could be causing this? rather annoying as the shut downs are completely random.

Are times it's happened (not that its any use) so basically every few days i'm getting it and it's completely random.
 
Still causing problems

only done it a few times since I've posted this though, also is 60-80 degrees a bit much for the graphics card or about right? :p
 
i had a similar problem a few years ago, only happened when pushing the GPU and it was all down to the power supply.

However you mention Skype....
My son has a gaming set up and kept getting BSOD, it took much digging to solve this, but it eventually came down to skype and talking on the mic at the same time as gaming (plenty of forum discussions on this). un-installed skype and the problem went away. He has now reinstalled skype and manages to use the cam mic without problems.
 
3 minutes after I posted the above it happened again, then again at 22:11 then again 5 minutes ago

It went from doing it once every few days to doing it 6 times in 24 hours?
 
Know if you have sufficient air-flow for your case? It looks as if it is happening more often now that we're experiencing humid weather.

If the computer restarts after prolonged use, but then, after that, it keeps restarting more frequently (computer has not been turned off), it usually indicates a heat issue.

I've had the above occur due to the insane heatwave of August 2003. The hard drive became too hot and caused subsequent and abrupt restarts.
 
that's what i've been thinking

the case is behind my monitor (side/window fan points to monitor with about 10cm space between them), above the case there is a shelf (7 or 8 cm) but theres plenty of space behind the case

^ as far as fans are concerned, within the case the air flow is fine and won't/shouldn't be an issue.

Atm doing what I usually do the gpu is at 62° so that shouldn't be an issue (it'll be same when it's crashing), fans inside case running at 80% according to fan controller and 36° avg temp.

Computer doesn't turn off (not completely) it just does the lines across screen

images
is sort of what it looks like but over full screen

after that happens it instantly restarts and boots back up.

It's not even that hot within my room so I doubt the temperatures are too hot (if so then surely cpu should be above 45, gpu above 62)

@Matt, due to fault with PSU or unable to handle the components?
 
I had something similar and it turned out to be one of the psu cables to my GTX580.
Trying to install everything neatly I had to bend the end of the cables where they went into the socket on the graphics card quite sharply, this must have loosened one of the connectors, a lot of the time it was ok but on the odd occassion my pc would reboot itself, on the offchance I replaced the cables with two more I had with the psu more directly to the card without bending so much and everything has been fine since.
 
if it continues today i'll take out graphics card, reseat it (yet again!!!) and try removing all power cables etc and re-doing 'em.
