check overheating, and / or cpu temp settings in the bios

Yep sounds like GPU overheating.


But do check if the back case fan is blowing out and not in, as it could be recirculating hot air.

thanks.
il chek.but all 3 collers work gut.
all chek temperatur of pc uts about 33.its normal oder not?
what i need to look in BIOS? and what to do?
thanks again.

how much digris must be in cpu temp settings in the bios?

The BIOS doesn't show the temperature of your video card. Get a system info software, like e.g. Lavalys Everest (in this software, see Computer/Sensor/GPU).

problem
 

i was installing the everest-3.3
temper of grafik kard ist about 45 grad.when i play game its about 53-
now i was chang the driver.
after some time black screen come again,this time whith out the lines.looks like i was restartin PC
only after i take it out the power and put it back its startet working again.What is it.HElp.

The display went away because the temperature of the video card wen too high? Check the fan (oil or replace it, if needed), check the fans in the PC case (perhaps, they cannot blow the heat away from th inside), don't overclock the video card, take the PC to the shop where you bought the video card...

................and make sure dust build up is not blocking the fan vents.

... or even the fans themselves. (Very good comment, Grumpy; recently ran into this! :)) This may also mean a 10 degree difference!

thanks for tryin to help me.
but....
i dont think thats happend beqouse of overhiting,one time thats happend right after i turn on my PC.there was no time for overheating-
and temperatur of PC 33.degris
and grafik card 43 deg,after i finish playing its about 53 butafter 1-2 min its go down-its normal temperatur.
first time when its happend it was black screen wtith green lines,after i change a driver its come now only black screen.and this problem whith restart and turn off PC,when this happend i kannt do it,only take it out from power,whei i take it back evrithing fine.PC work ,maybe 1 houh maybe 1day.but than again,
so.....?????

They, at least, won't have to do "remote doctoring"... ;)

Its definetly a GFX problem, even when you changed drivers you get a new look to an old problem.

yes,i think so,maybe i need reinstall driver,i was instal the driver over the old driver whith out uninstall.what do u think

No buddy, its a hardware fault, if the graphic card is still under warranty get it replaced.
