Sapphire 4870 1GB died when I switched Oblivion to 1920 x 1080 and full graphics settings

[Specialman]

Hello.

My Sapphire died when I just clicked "OK" button in Oblivion's menu after changing graphics settings to that 1920x1080 (My 24" Benqs maximum) and I also changed all the graphics settings to maximum. So after clicking that button screen went black with message box on screen which stated that "no signal detected", also Sapphires fan started to spin on maximum revs. After restarting computer GPU was still revving.

I went to a local PC store and they tested my pc and said that my GPU is dead. Today I am going to send it back there where I purchased it.

So does this sound new or known problem and could I have caused it?

This is my hardware (not overclocked):

GPU: Sapphire Radeon 4870 1GB
MB: Asus P5Q
PSU: Antec Neo He/Neo Power 430w (too small? Could this kill GPU?)
CPU: Intel core duo E8500
CPU cooler: OCZ Vendetta 2
"The BOX" (I don't know what is it in english): Antec P182 (Should be good, three 12cm fans and so)
memory: 4x2GB kingston 800Mhz
Hard drive: Samsung spinpoint 750GB 7200 rpm
CD/DVD RW: Samsung some cheap basic thing

Pardon my english I only speak finnish properly.

How long did you had that card?

The PSU is rather small for your system, although if nothing was overclocked, it should have been enough, still a bit on the edge though.

My Sapphire 4870 died, a different death though. I would get atixxxx,sys BSOD when loading into windows.

They replaced my card without a problem.

This is definately not a known problem! Sounds like you just had bac luck - the GPU was probably ready to fail and going to those settings just tipped the scale. Hopefully you can return it and have it replaced.

The PSU does seem a little small. However in reviews I've seen test computers using about 285 watts of power (total wall outlet power) under full load with an HD3870. That was with Core 2 Extreme QX9770 cpu, so your system shouldn';t use any more power than that.

Hello again and thank's for your answers.

I'm sorry that I forgot to mention how long I had that card. I had it only two months!

I went to Antecs home page and there was some kind of PSU calculator which said that even less than 300 watt PSU would be enough.

Thanks for the link kmmatney.
