Hi, I recently installed Boinc on my my Windows 7 partition, and started crunching numbers with my GPU for milkyway@home. Twice in a row when I leave it over night I have a 'hard hang' which is, you cannot even reboot holding down the power button!! :( I have latest drivers for all chipset, service pack 1 for OS, latest ATI drivers, and a nice case and cooling and I'm a gamer and it never wigs out in games. I aslo tested my PSU with a PSU tester and according to that its all good (although I'm not sure how to find out what it's putting out under load) Anyway, do you think my GPU is bad? PSU is bad? Overheating? I have Gigabyte GA-P55A-UD3 mobo. i7 860 CPU, 4 gig G-SKILL DDR 1600 ram, and XFX Radeon 5850 black edition. PSU is ANTEC 650 watt. ANTEC 900 case, Corsair H-50 water cooler on cpu. Oh, and I have used seti@home CPU client for days on end and never had a problem. Thanks if anyone can give me any pointers. |

Hi,I've had issues with the last few Windows ATI drivers BSODing my system. I haven't been in Windows for a while, but I think downgrading to 10.10 fixed it for me. The 11.* releases might have fixed it; I haven't tried it. |

Same issue here, I used the Overdrive from ATI to slow Down the Memory Speed. My 5870 was very unstable if using it as default 1200 MHz memory speed... I drop it to 1000 MHz settings and the GPU I increase from 850 to 900 MHz and everything working fine. |
