Hello
I need some help with my rig. It keeps crashing and I do not know why.
I have 4 X 750TI Geforce GTX Gigabytes and I am mining using ccminer v1.1 ccminer35-50.exe. Not sure who's flavor it is but it has always worked.
The problem is that I can run each card separately one at a time but as soon as I start a second one I get a pink screen and it crashes and restarts the PC. Like I said, each card running separately will pump out over 5 MHS but as soon as I start a second one it goes poof.
Now this thing, up until yesterday, it worked fine. All four GPU's running at once.
I do not know if this the reason but I did try and install the new GeoForce 340.52 driver but the install failed. So I rolled back the Win-7 64-bit PC to a restore point and started mining again. It worked from about 8:30 PM last night until about 3:40 this morning (all 4 cards at same time) then went down again. I tried multiple times after this to run the rig but it keeps crashing. So then I started running card each separately to try and id a bad card but all 4 work separately as described above.
So I tried to reinstall 340.52 again and this time the install worked. Problem is I still can not run more than one GPU at a time or it crashes.
I don't think a card is bad because I can get each to work by itself. I know it is not the PSU because I have a 1000 Watt Corsair. I have 16 GB of RAM and another 16 to put in if I need to but I do not think that it is necessary.
Anyone have any ideas what is happening or what to check?
Thanks

Are you using Precision? I have had a problem twice now. The first time it happened, I was sure I blew a card. After three days of google-ing and multi forum posting, someone asked me if I used Precision, and said that sometimes the config files for precision get corrupted, and there's basically no fixing them for some weird reason. He told me to uninstall Precision, and make sure to select the option to remove all profiles, then re-install. Well, it worked. Had been this all along. Meanwhile I had rolled back drivers, tried older and older drivers, uninstalled manually all drivers and files by going through the registry... three days, and it was Precision all along. Don't know if this will help you, but I figured it was worth a shot.
Showing my noob here but I know nothing about Precision. I never installed it and do not see it in my list of installed programs. Perhaps I will just reformat the HD and start from square one. I have hardly anything on the rig so other than time, nothing lost.
