Mining rig crashes, any suggestions?

[LouReed]

Ok, so I've been running my rig for 3 months non stop with no troubles, and the other day it just stopped running. When I start the pc up, and fire up CGminer, it immediately freezes up, and needs to be rebooted. No blue screen, and no errors. I'm running 3 of these cards, and mining LTC:

SAPPHIRE 100352-4L Radeon HD 7950.

My guess would be that I have a bad card, and if so, is there a good way to test them?

Thanks in advance for any help!

If it were me, I would do either one of two things (depending on how lazy I was feeling at the time).  Either:

1) Pull out two of the cards and test just one.  If it runs, put the next one in.  If all of them run, then try running two cards, and then finally all 3 again.

2) If I am too lazy to do that, go through and disable the other cards in your command line arguments (assuming you are using cgminer or bfgminer). Again, start by running each card separately, then two cards, then all three again.

It may also be a hardware issue (HDD failure, board going bad, PSU, RAM).  Only way to find out what it is to first verify your software settings are correct (which they sound like they are if you havent changed anything), then start diagnosing each on component individually.  If all that seems to check out, maybe try a fresh OS install.

Thank you for the response!

How exactly would I go about disabling the cards through the cgminer command? I had someone else set up everything for me, and I don't want to mess anything up. My rig is not actually at my house, but I am able to connect to it via Teamviewer. Would I just go through and delete all of the values for one card at a time, and so forth until all three are checked out?

Thanks again!

Are you using a config file or command line?
