pink screen of death

[bgh251f2]

does anyone know what is causing this horrible crash+pink screen and/or how to fix it? it only happens while playing games. First noticed on Doom3, Fear, and now Stalker, and even sid meirs Pirates (much lower system req's)
here's my current setup im running on:

mobo: asus p5b-deluxe
cpu: e6600 @3.7GHz (<55*C under load)
Ram: corsair xms2 8500. running at 820MHz 4-4-4-12
GFX: bfg 8800gtx (stock speeds)

also, it has happened while running the cpu at 3.2GHz (<48*C under load), and the ram at its native 1066Mhz 5-5-5-15

What PSU are you using?

[bgh251f2]

Enermax Liberty 620W, should be plenty no?

[manwithnoname]

Does it happen when the run the CPU at stock and the ram at stock?

[bgh251f2]

yes

[muddyfox470]

Check your connections inside your PC (power etc) and ensure the fan is running fine, force it to run at 100% if need be.
(same with CPU fan)

Have a look at the line voltages (although I doubt it could be your PC) just to see if there is any variation and if so, how much.

Finally when did this problem start happening, is it only a recent occurrence (or has it happened since you built the rig), any software install/drivers?
Look over what you have installed/changed before this started happening that's about it from me

all the power connections are fine, checked that ages ago, and last nite when it last happened. cpu fan is at 100% allways, tis a zalman 9700cu btw.

how can i check the speed of the gfx cooler's fan? possible with n-tune maybe? although my p5b-delexe doesnt have an nforce chipset, its a P965.

not a recent problem, although i thought it went away for a few weeks, untill it happended again.

all ive done recently is update the forceware for the 8800.

Graphics card is overheating, or already toasted...

[Curly]

I'm with scrandman... it's the gfx card overheating, best bet is check the fans running and the heatsink is on correctly if you still get the problem its RMA time.

you know when summers coming, the cards start overheating

it could be because of inadequate case cooling, bad graphics card cooler (or bad settings forcing the speed too low), however normally the graphics cards are good to extremely hot temps ~ 120 (so look in your graphics card driver info for temps and post them here) as normally the gfx cards are good at self regulation and you will see them throttle before any graphics garbling like that starts to happen

did you have any problems in the lead up to this, i.e. loud fan noises / lots of vibrations etc ()as it could mean the fan on the graphics card cooler has gone)

sort out graphics card cooler and case cooling for adequate air flow, make sure that air going out of case is greater than air coming in

Ian

then again it might not have anything to do with the cooling card and it could just be b0rked, either the pipes or the gfx memory, these things do happen, and only rear their head when the going gets tough (3d apps)

[bgh251f2]

Well it's in an Antec nine hundred case so I should imagine air flow is good, it's got more fans than a geisha convention, one thing I'm not too sure about is that having the PSU at the bottom theres a fkin beefy 120mm fan in it thats drawing air down away from the graphics cards intake fan, you reckon that could interfear to enough of a degree to cause it to overheat?

Also what 8800gtx coolers are worth buying? It's just got the BFG stock cooler on it atm, been looking at the Thermalright HR-03 Plus, anything better than that? Or would that even be good enough?

BTW its cold here ATM so summers not affecting it And why more air going out than in?

[Jay]

what are you using to measure the temps and what do you class as "load"

[bgh251f2]

SpeedFan for the CPU temps, 'load' would be running something like S.T.A.L.K.E.R. on full everything graphics wise for a few hours.

Ran some CPU stress test on it a while back too, the name of it escapes me at the moment, but it hit about the same temps as running stalker.

[muddyfox470]

Check out your temps (Graphics Card - you may as well check your line voltages whilst you're at it), if it is overheating I would send it straight back to the Point of Purchase or the manufacturer for a direct replacement as it sounds like you have the optimum settings for such a high powered graphics card.

The stock cooler should be able to cope with all those games in that case, so I wouldn't spend any more money if it ain't working. Most people buy 3rd party coolers to reduce noise over temps.

If it isn't the temps just sounds like the graphics card is a tad broken, so I would send it back

Ian

=========================================
With regards to the more air out than in, if you have more air being pulled into the case than being kicked out, you will have a build up of air that can't do anything, but hang around and get hot, this rises the overall temp of the case etc.
