when i played battle field bad company 2 for 7 and a half hours i got stripes on my screen(like a tv out of tune) and i lost sound and after a while it comes back sometimes but when i exit sounds back.

at that time my gpu as runing at +- 64 C and cpu at 45 C

i have a gigabyte radeon hd 4890 1gb ddr5,4gb ddr3 1333mhz ram, a phenom2 x4 940 BE with a thermaltake blue orb 2, msi 790FX-GD70 winki edition motherboard, a 700w sli ready power supply, os windows 7

most probably a driver problem, I had the sound problem in TDU a driver update fixed it, and can you please state the make and model of that 700w psu?

thanks.

i am using a huntkey max700w apfc power powersupply

i don't think that the problem is drivers it only did this with battle field bad company 2 and not with eg: need for speed shift

I would pay more attention to why you were sitting in a chair playing games for 7.5 hours, but maybe that's just me.

Your machine is probably fine. I would bet the game just crashed. I doubt very many people played it that long during testing.

Containment Breach

Do not meddle in the affairs of archers, for they are subtle and quick to anger.

i would ask,
is this the first time this has happened?
what size is the page-file / virtual memory on your computer?
is it on the system drive?
(the last two question isnt that related to the problem, just having the page-file on a separate hdd to the O/S, can help reduce load times and reduce wear on a hard disc.)

if this is the first time its happened, play as normal until the problem appears again, to determine what is common between the fault.

Hit it with a Hammer.
CPU: AMD Phenom II 955 @ 3.8 ~ 4 Ghz (Cooler Master V8 Heatsink)
Graphics: 2 x HD 5770
RAM: 8 GB (standard clock: PC3-1333)
Motherboard: ASUS M4A78T-E (790GX)
Sound: ASUS Xonar DX
Case: CM 690 (with custom paint and a 800W PSU)

os (windows 7 extreme r1 64-bit) no it's not the first time it did that the first time it happend when i played music +- 5 hours then and the sound didn't come back but i swithed off the machine for an hour and switched it back on and every thing was back to normal
windows programs eg: printer,eset,nero is on a 250gb hdd only and games and other files are on a 1000gb hdd

ram? could be overheating? maybe you overclocked and it isnt 100% stable?

i would look at temps also. after 2 hours of gaming for me temps are high and i manually set the fan on the gpu to like 75% or maybe your computer is telling you to take a break

they dont make a phenom11x4 940BE am3 you must have a typo

when i stress test my graphics card the grapics starts to stutter and my fan speed slows down and fan lights start to dim. i have both 6-pin plugs pluged in from my powersupply to the graphics card. when i stress test it the temp becomes 75-80 at max when idle i get 40-50.

can you test your psu that would be first thought some stores have free psu testing

you have 4 12v rails at 18amps each right?
i dont know the formula but it should be enough but i would have the psu checked or buy a new one i dont know that brand and it sound like a psu issue

I hve tested my powersupply and there was no problems i also found out that my graphics card is hissing and not my psu and also it sometimes starts to hiss when scrolling down.

Since your PSU has four +12v rails, you have to make sure both PCI-E connectors to the graphic card are on dedicated rails.
This is one of the problems with PSU's that have multiple +12v rails.
My first thought is that your graphic card is overheating or is overclocked too high.
Graphical corruption like you described in your first post is either a temp issue or too high of an overclock on the GPU memory.

stripes? this has been a known problem on some ATI cards. I sure as hell had it once or twice. Driver update rectified the problem. Annoying as hell it was.
