hi, iam the IT Administrator supporting 1000+ desktops. we have an issue with dell gx270 machines. When users login and go for their breaks , when they come back to unlock the PC reboots automatically.
I have done few tests
1) checked eventviewer but there were no error log.
2) there were no irq conflicts
3) done bios update
4) replaced heat sink and motherboard fan
5) ran dell diagnostic utility tool and all tests passed.
6) replaced memory sticks
dell has no clue about this incident but we have around 30 pc’s which have reported this problem.
when computer wont respond to keystroke or mouse, checked CPU and i could see led blue and powersupply on, could see some activity on the rare side of PC. the only option is poweroff manually and pull power cable and then plug it back and restart.
does anybody has clue how to get this fixed.
