Computer Freezing under load

Trixx worked, just ran the furmark burn in test with no problems at all, which the pc would have crashed whilst doing before.
could the problem be i am trying to draw too much power off the sata power connections?
i read somewhere that they cannot deliver as much as molex?

Is this your PSU? its actually a 400 Watt PSU, i should have spotted that earlier, sorry, as its a Corsair PSU i assumed what is written on the box is what the 12v rail gives, turns out its not, its 408 Watts.

GPU: 180 - 200 Watts
CPU: 95 to 125 Watts
Rest of system: ~100 Watts

Its difficult to tell, it might be within limits or it might not be enough, i don't know.

You could try a Molex to 6 pin adapter

But really, if your able to return it and get your money back? i would do so and get a stronger PSU.

ahh right well i think i have one lieing around anyway, so i will try that ... else i guess i need an upgrade.
Doubt i will be able to return it tho, but i will give it a go.
 
You say it is freezing under load, have you made sure it is warm and nothing heavy resting on it?
 
Have you tried different drivers? some older 13.9's here

Once all the main culprits have been exhausted finding the problem becomes a nightmare, especially doing it remotely.
 
well i dont think that it is a diver issue :(
just uninstalled my drivers using display driver uninstall utility and then reinstalled, nothing.
still crashing ...
btw im using furmark to run the stress test, and it only seems to crash when anti aliasing is on, presumable be cause the card is finding harder?
tempted to reinstall windows and format some drives ... cannot think of anything else to do, could it be the card its self is at fault?

Furmark? Furmark is a tress testing utility of the most extreme description, it has even been known to make perfectly healthy GPU's go BANG.

It stresses the card way way way beyond what it will run in its life outside of Furmark, with it the GPU also uses way more power than it normally does.

Use 3DMark, Unigine and games of some description to test the card. if you don't have any problems there? then there is nothing wrong :)
 
You could have a dodgy card that doesn't like running at it's factory clocks, which would mean sending it back for RMA. You should test it in another system first though.

Assuming you tried removing all drivers with DDU (can find this here) this will make sure it's not a driver issue, you could always go for a fresh Windows install too although I know that can be a right pain.
 
yeah , it came factory overclocked... so i could try and remove that i guess.... i did just remove drivers with ddu yeah, might try a fresh bit of windows tho if thats one of the only options left.
 
Just ran heaven, managed to get though the test ok i think, might have crashed for about 1 second, but then i think a scene change might have fixed it? lasted a benchmark tho, the only think that I am worried about it happening during somthing like cs:go , and then receiving a ban :/
set the clock speed back to the stock, and it seems to be slightly more stable that it has been, tomorrow i will test it with these clock speeds in some cs:go and see if it manages to last a few matches....
 
still crashing occasionally, so I am doing a windows reinstall, and whilst I am at it, i have decided to (upgrade?) to windows 8.1
 
Just reinstalled windows, after formatting the HDD, still crashing under load. looks like its time for a replacement part.
