AMD Radeon HD 7850 problems

Hello all. I've built a pc for the first time in about 13 years. I've been using manufactured computers and laptops, and decided to build my own this time. First, my new baby is:

Gigabyte Radeon HD 7850
AMD FX-8120 3.1Ghz
ASUS M5A97 (OC version)
Sandisk Extreme 240Gb SSD
8Gb DDR3
Windows 7 64-bit
Inland 500w PS
Zalman Z11 Plus Chasis


So the problem I've having is the video drivers crashing and recovering. It happens fairly often, while I'm surfing the net (including trying to sign up for this site and typing up this post). I've tried (in no particular order)

* reformatting and using drivers on disc that came with the card
* reformatting and going straight to the v12.8 catalyst from AMD's site
* turning off the overclocking on the CPU

I've tried a couple of power supply calculator sites, and those vary greatly. Thermaltake said I only need 350W, ASUS (whom I'm a little more likely to trust) said I need at least 650W.

I'm unsure of what to do. At first, I was thinking maybe the card itself had a manufacturing defect. Now I'm wondering if it's because the power supply is too low. So I'm looking for your opinions. I'm happy to provide any other information, but you might need to tell me where to get it. The technology has changed a lot in 13 years. Thanks for any help.

Well, 500w should be plenty for that, so it could be the card is defect. I had crashing with my 7850, but that was on beta drivers, and went away with the 12.8 update.

You can try removing the card, cleaning and putting it back in, but that sure seems like a long shot to me.

PSU brand is important -- I really donĀ“t know this Inland 500w PS, but I suspect it is the cause of the issue you have.

Yeah, I thought 500w should have been plenty. It's not like computers get that close to the peak power often. And certainly not while reading a forum. I'll try reseating the card. If that doesn't work, then I'll try and return it. I put in a ticket with Gigabyte, but it's been about 24 hours and they haven't even looked at it yet.

Well, I've decided I'm just going to return the card. The drivers are crashing every couple of minutes and sometimes the card stops sending output to the port so the monitor doesn't even see any signal. Hopefully getting a new card will rectify the problem. I'll update this weekend when I can switch out cards.
