My Sapphire 6850 arrived today and is now installed. It installed fine and the drivers are up to date. I was running Metro2033, I decided to see how much power the card had, so I turned on DX11 mode and knocked the settings up to very high. It ran fairly smoothly, but after about 5 minutes of playing, my computer just died.

I thought the card must have overheated, so I ran a benchmarking test and monitored the temperature. It died again during the test, but the temp was below 50 under full load.

My PSU is 700W, but it was very cheap. I'm wondering if this could be the cause? Also, does this pose a threat to my system?

Post full specs, make, models,brands...

did you install the latest drivers for the card? [I can not help you there as I could never understand ATI drivers so pretty much never ever went back to ATI for multiple reasons... I do often try every few years and never succeed in keeping one]

are your additional power cables attached correctly?

Are you using temp addon cables?

does it require external power aside from the PCI-e slot?

did you try a bios default setting?

does your system meet the basic spec?

urm many reasons... but like you identified it may be your psu being too cheap...

I never buy cheap PSU's the risk is far too high... and my rig costs a clean £1000

EDIT

Corrected typos

CPU: AMD Athlon x4 [email protected]
Motherboard: Unknown, but my friend has the same motherboard/gfx card as me without problems.
RAM: 4GB

Running 32bit Windows (I'm aware that I should be running 64bit, doubt that causes the problem?)

The card requires a single sixpin, which is correctly inserted. The bios have not been changed from default. My system does indeed meet the spec.

Check the cables on both ends if yu got modular...

Even though you got the same board make and model does not mean they are identical... Check and compare bios ersions...

Use CPU-Z [cpuid] to determine your board make and model without opening up haha I hate reading board labels... so difficult [specially for partially sighted people]

What about the make of your PSU?

Try downloading the latest DirectX redistributable to ensure you have the very latest DX release... I read before that ATI is fussy over this aspect.

latest redis
http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=8109

And the developer center for the SDK
http://msdn.microsoft.com/en-gb/directx/

woo win8 download link... bugger where did that licence key link go...

EDIT

Found it

I know that was offtopic but might as well complete the whole thing since I mentioned it lol

It might be because your cheap power supply can't pump out the power it needs. Tell us the model or the amperage on 12v lines,it should be all on the sticker on the PSU. Your computer can't just simply shutdown from a simple software problem,so check your PSU first.

Funny that ... the AMPerage was my next thing to mention... as soon as I saw I had a new email for this thread lol...

EDIT

its also why I asked for makes and models and brands...

It does sound like you have power issues.

If it is power then yes it does pose a threat to your system.

back up all your important data on a removable drive.

one thing that will happen is your hdd will randomly lose its file system on crash. Also you will fry your ram chips.

I know because I had this same problem with my old pc.

It would run fine, until something graphic intensive was happening and then just suddenly shut down.

cost me 2 hard drives, irreplaceable data and four 2gig chips to realize what the problem was. (stupidity can burn -but hey, lesson learned)

now I have become captain power source spreading the word and unleashing the awesome power of apples.

Sometimes I like to use words out of contents

I'm going to go with the PSU problem then, as googling seems to point to that being the cause. @Kezzla, I can't get a new PSU until at least Thursday (Payday), will my computer be okay so long as I don't put any stress on the GPU?

When you upgrade your video card you need to upgrade your power supply. As suggested above you need more power. Ultimately what you will do if you continue to use it with out upgrading the power supply, you will fry your motherboard or cause over heating issues.

If your using card based video in todays world, I would recomend around 600 or higher. The better the gfx card is; the higher the watt output you need from your power supply. If you are using a high end gfx card, consider something with 1200 watt or better. That may be a bit of a overkill but Id rather overkill then fry a board. Plus the power supply will likely out last that computer anyway. You will be able to use it in your next build as well.

It should be fine if you keep it down,I would monitor it as apps may randomly stress the GPU(Flash bugs).

I guess I could try not using my computer for a few days, and you know.. Have a life but it seems unlikely, I may just take the card out and... put the old one in. *sniff*

It was definitely the PSU, just installed my Corsair 750W, not a problem now, considerable weight difference, and noise reduction, really impressive quality xD
