New game / New Graphics card.

But in a post further up this thread some chap posted a link to my power supply spec, stating that it was more then suitable for the job......

Ok, so If I go out and spend £50 on a new power supply and it still crashes the PC, who's going to refund me the £270 I will have spent......

One way to look at this - if you ever plan on upgrading your PC in the future, you will absolutely need a new PSU.

Although your current PSU is a 750W model, the fact that it doesn't come with more than one PCI-E power connector means that it's not intended to be used with such a graphics card.

I believe almost all mid range, some budget GPU's also, require at least two 6 pin PCI-E connectors. Some require just one 8 pin PCI-E connector, it varies.

Buying a quality PSU now, such as the Superflower one suggested, would be a good investment for the future. It has a 5 year warranty, OCUK themselves honor this warranty, plus it will power any mid range GPU you'll buy in the next few years without any problems.

I'd suggest buying the new PSU, or waiting until you can comfortably afford it. It should enable your 7950 (cracking card for the money btw) to run flawlessly.

No. The PC crashes showing a black screen with blue lines after a few minutes of playing a game.

If I fit my old display card it's fine.

Answer seems to be that I need to spend more money.

Did you try a proper removal of old GFX drivers and a clean install of the latest AMD driver?

This one: http://www.overclockers.co.uk/showproduct.php?prodid=CA-002-SF&groupid=701&catid=123&subcat=2057

If you think a 450wt will do then ok.

nope that 450w psu cant handle it while it has 37a which is less than your psu's 44a. it will be no way to run 7950 card with that psu at full load properly as it is underpowered. accorded to amd spec it required 25a and 500w psu minimum then you add up 15a from your cpu, cpu cooler, memory sticks and motherboard power. plus the rest to add up like add on pci cards, pci express cards, hard drives, dvd-rw or blu-ray drive and case fans you had not listed fully. my mate had same issue ran gta iv on new pc with 450w psu with just 15a it cannot handled system full loaded with cpu, cpu cooler, motherboard, 1 wifi pci card, dvd-rom, 2 hard drives, 2 psu fans and geforce 8600 gts graphic card fan. all combined would used over 39a, geforce 8600 gts required 24a and 350w psu minimum so he thought it would worked fine with 450w psu but it not, the amperage power is far too small.

i read this thread through last page and was stunned that you got lots of air in your case with 1 front mounted intake fan, 2 rear internal exhaust fans, cpu fan, 2 top mounted ram cooler fans, 2 display card fans and the fan in the psu. so that 9 fans ran all times but i think that far too much and probably used up all 4 molex psu cables and closer to 44a maxed. wonder why did you used 2 ram cooler fans on corsair dominator ram sticks as it already has ram heatsinks? do you overclocked your cpu and ram?

9 fans? holy crap, guess you absolutely need a bigger psu. i only just have 1 near 120mm fan ran all time with corsair h80 radiator, 2 msi gtx 970 fans are silent at idle and corsair ax850 psu fan always silent at idle and full load but don't have fan on ram sticks as it never get hot and did not have heatsinks on it. :)

i thought you were send card back to ocuk for full refund? but sent card to australia? i am confused, msi has uk rma service here in coventry.

i would suggest you to try clean uninstall old amd driver with display driver uninstaller, shutdown and powered off pc to install 7950 back in then powered on pc and install new driver.

Also try download MSI Live Update 6.0.012 to check if there is new BIOS for your 7950 that could fix your issues and download MSI Afterburner to monitor GPU core temperature.

http://uk.msi.com/support/vga/R7950_TF_3GD5OC_BE.html#down-utility&Win8.1 64

If the above didn't fix it then maybe you could try disconnect some system fans because it is excess, I suggest to disconnect 2 RAM coolers fans, absolutely unnecessary as it already has heatsink coolers.

Hows about this, if you are adamant it is your graphics card I will just replace this no questions asked?

Please provide me with your order number and I will personally swap the card with a new one when I am back in work on Monday

You cannot get any fairer than that.

I believe OcUK wouldn't lie to you about it working/not working. I had 1 problem, and RMA'd and they sent out a replacement straight away after testing it.

Personally 450W Power Suuply is low and after reading some of the reviews I have seen on your current PSU, I would bet that it is that which is causing you the problems.

Hi Bailey

I received the email below from Dave Middling this morning and have taken up his offer of a new power supply. I just completed the payment process so it should be with me next week. If the display card is still causing shut downs and showing the black / blue screen I will take you up on your offer of Overclockers supplying me with a new display card.

I truly appreciate your offer and that of Dave Middling.

Kind Regards

Trebz

The power supply in question is: http://www.overclockers.co.uk/showproduct.php?prodid=CA-013-SF

Hi There,

I noticed your thread in the forums, and while it does seem to me the PSU is the weak link our support guys could have done more to help than just send the card back to you, sorry for that.

Some people suggested some okay PSUs, but if you use the voucher code '*******' it will let you have CA-013-SF for just £40+VAT. This is quite a bit under cost, but we break even considering the graphics card so it's all good. This is a truly great PSU that will last you for years of upgrades (assuming you don't go mad with £1000 worth of tri-sli).

ps. This voucher code can be used only once, so it's just for you :)
pps. The voucher can only be used online, but if you wanted to get running straight away you can order it on the website for shop collect (open until 5pm Saturday, closed Sunday sadly).
Regards,

Dave Middling

The SuperFlower 450W will provide more power on the 12v rails than the Arctic 700W which fails to state the combined output of its 12v rails. You don't just add the output of the rails to get the combined output as you mistakenly did, for your information. When one rail is maxed, the output of the other rail typically cannot be maxed at the same time.

The higher the quality of the PSU, the more the second (or more) rails can also be maxed along with the first, producing a combined output very close to (but usually not exactly the same as) the total arrived at by adding each rail output.

When a manufacturer fails to state the combined output of 12v's, it's usually for a reason.

Do I recommend the SuperFlower 450W for that GPU? No. It's better but play it safe and go 500 or slightly above.

To check if there's a new BIOS, okay. But don't use LiveUpdate to flash BIOS through Windows (which is how it does it). It's a hell of a gamble and many mobos have been bricked like that. Do it through manually downloading the new BIOS and using a jump drive to flash through the existing BIOS itself.


And just saw your latest post, Trebz. That's a fantastic PSU you've been offered.
 
Fantastic psu there, I have the same and paid a lot more for it! Well played OcUK on once again sorting out your customers :)
 
what a cracking offer.
looking at the specs and reviews of the psu you would have to be nuts to knock that one back... nice one OcUK
 
Hi All

Fingers crossed this will finally put this issue to bed.

For the record though, I'd like it understood that I did not ask for the power supply and did not write a begging letter or pass on any threats.

This was offered to me by Overclockers without my asking.

They didn't have to do it, they just did.

Karma will be awarded when the time comes OC dudes.
