I recently built a new computer for the first time using the same parts as the 500 dollar march system builder that they built on this site. When I have the HD 6850 installed, most applications crash the computer. I have tried many different driver versions but none seem to work. Also the cheap geforce 210 that I bought to troubleshoot works perfectly.

if you've tried everything, then contact the manufacturer as you may have a faulty card. have you check system temps? hope this helped.

I've already returned one card and I am getting the same problem with the second so I don't think is is faulty. I haven't checked the temps yet but I'll try that.

I'm not familliar with the $500 system on here, but what PSU is it? it could be that the card isn't getting enough power.

It's the Antec EarthWatts Green EA380D 380 W. I did wonder if it had enough power but they managed to not only use it but overclock using it which I am not doing.

that is quite strange. I would also think that a 380W psu is way underpowered, but if it did work for them then it should for you. The case seems fine also, but I would personally add all of the fans that I could to make the GPU as cool as possible. If it is a sapphire card you're using, I've found that their reliability is top-notch. I would call sapphire up, and check with them and see if you've left out somthing critical (no offence) I would check that all of the drivers are up to date but other than that, sorry I couldn't be of help.

Antec usually makes great power supplies, but you can't blame them if you've received a faulty unit. I would check the PSU to make sure that it isn't the problem.

you need a new PSU with more then 500w

Also occasionally instead of crashing the program will just close and a notification will say that the display driver stopped responding and has recovered.

I have now tried a 650 W power supply and I am still having the same problems

Then its not a PSU issue. Do a clean reinstall of the drivers using Driver Sweeper.

I have done that many times. In fact, I just wiped my hard drive and reinstalled everything as a last resort and still no luck.

I gave up and traded in for a gtx 460 and now everything works. Guess the drivers didn't work.
