Hello,we have Dell Optiplex 980 with Windows 7 Professional Edition 64 bit installed on it. After installing just the system PC unexpectedly restarts itself time per time. Ususally once per day, but sometimes it runs 2-3 days without restart, sometimes it restarts more than 1 per day.We tried to reinstall the system from CD, first one was preinstalled on the PC. We tried to install the newest drivers, problem is still there. We tried already 2 computers, both are experiencing the same syptoms. Some hardware details( CPU: i5 650, 8GB RAM, 2x HDD 500 GB SATA)In Windows system logs there isn't anything usable just information about unexpected shutdown caused probably by power failure (outage).Anyone else who has experienced the same problem or knows what can be the problem?Thanks, Jan.

Are you having any static electricity problems? That is one potential issue. Are you using UPS systems with these units? (if no, you should be).

Yes, we have UPS system. Electricity outage is surely not the issue. We have next 25 other computers which runs on the same electrics and they weren't restarted for several weeks already. I thought if this is some known Windows or drivers or BIOS version issue or something like that.
