Did you find what was going wrong? Because, i've a similar compatibility problem with HD7950 and 5850. Lot of HW errors and regulars crashes :/
The HW Nonce errors with the 5850 were common for me when running at Intensity of 19... I changed it to 17 and it didn't really suffer much on the hashing speed, but it significantly cleared up the HW errors.
As far as the crashes go, when do they happen? What is crashing? CGMiner or the whole computer?
What PSU are you using?
I had the hardest time getting my 5850 to play nice with my 6850.
After a frustrating few days of troubleshooting, I decided to chill out and do a fresh install of Windows.
Installed Windows 7 64-bit, and Catalyst 13.1, did all of the updates for Windows and they have been skipping along like two friends at recess ever since.

I agree that it sounds like a bios issue. Im only familiar with gigabyte 7970s but I have had nightmares "upgrading" the bios. Their may be a chance that what you think are the latest drivers for your card are the latest for a different card with same model number. For example two 7970s purchased same time from newegg, one has bios F3 while other has bios F72. F3 bios can only be upgrade to bios F4-F9 while bios F72 can only be upgrade to bios F73-79 when they eventually come out. Check the manufacture of your cards website and try a different series maybe. I only flash bios with one card in system at a time and flashing outside of windows. Hope it works out for you.
okay flashing card bios did not work. I have the latest version of sdk direct from amd. My motherboard is msi 970A-G43, my cpu is an Athalon 2 x3, my os is Windows 7 Ultimate x64, or Windows 7 Professional x86(dual boot)...card crashes on either os. My drivers were downloaded directly from amd
I am almost ready to return the card, only problem with that is it was shipped from Canada so return shipping will cost half of what the card cost.
I have all my Windows updates installed. I have the core clock and memory set correctly based on afterburner.
I am not going to attempt "baking" the card as this is out of my league. Anyone else have any suggestions?

Try setting the card back to factory defaults and go from there. If you get it working at factory settings THEN you can tweak it.
I was mining with my 7850 and everything was going well. I bought a secondhand 5830 and added it to the motherboard. When I start cgminer it crashes immediately. If I try to mine without scrypt using guiminer at btcguild the 7850 still chuggs along getting shares, but the 5830 says it is hashing but no shares show up...even after an hour. I tried to do a fresh install of windows 7 in case it was a driver conflict but this did not work. If I remove the 7850, the 5830 can handle the output to monitor and I can play games, but cgminer still crashes with or without a cgminer.conf. The 7850 still mines fine if I remove the 5830, but while the 5830 is in there it will not allow me to open cgminer, even if the config file only has the 7850 assigned. I updated all drivers but still no good. Please help me

I had two different card set up before. And it works. I had one where it didn't work, and found out the
older card was having problems. I was crossing a 6950 with a 7950, and it wouldn't run at all.
I'd suspect a hardware issue with the 5830 if it can't mine.
Steps to fixing an corrupted video bios.
1) Go to http://www.techpowerup.com/vgabios/ Find your GPU BIOS. Download it.
2) Go here http://www.overclock.net/t/1353325/tutorial-atiwinflash-how-to-flash-the-bios-of-your-ati-cards
3) Follow all the steps, and instructions of the link above, download atiwinflash.
4) Flash it with the downloaded bios.
5) Should fix corrupted video bios.
Other then that make sure you have the latest Amd Catalyst. It should work.
Get Msi afterburner, find out the clocks for a 5830 HD online, and check to see
if your 5830 is at stock. If its not, manually clock them to 5830 clocks.
There is another method I heard, I never tried it. But I heard it works sometimes.
Taking four balls, foils on each corner, with board facing up.
http://www.addictivetips.com/hardware/fix-your-graphics-card-by-baking-in-oven/
Take the plate off, fan. Just bare board. Bake it for 10-12 mins at 385 F.
This can remelt all the solder points and even restore your card.
This is a last resort if all else fails!

Though its no guaranteed. Its about a 10-15% chance of working if your card is dead or having hard-ware issues
that aren't related to video bios or driver based.
I'll try to offer some help though I'm new here too and not terribly familiar with cgminer and guiminer.
What motherboard are you using and what is your PSU?
Have you installed all the Windows 7 updates? Specifically those related to .Net 4? I know you said you have the latest drivers installed but would you mind specifically listing what version of CCC and drivers you're using? Which 7850 and 5830 do you have and are you using drivers from the manufacturers or directly from ATI?
