My otherwise reliable Z800 started having issues that seem to be accelerating lately.
Anyone else is having the same symptoms where it reliably shuts down after cold when getting into Windows; and then sometimes shuts down during normal operation? If so, what fixed it, if anything: replacement PSU? Graphics card? mobo?
Thanks!
Symptoms:
- reliably shutd down on startup from cold - either while getting to the login prompt, or right after loggin in
- the shutdown is abrupt - i.e. an unexpected one, i.e. not OS-initiated. Nothing in the event logs.
- don't remember it to ever shut down like that before it gets to the Windows boot process - i.e. never during BIOS set up
- haven't been able to run hardware diagnostics from a flash drive or a DVD yet - just haven't gotten to it yet
- the issue started about a year ago - preceded by having to press the power button twice before it powers up
- if I let it sit at the BIOS boot prompt for 10-15 minutes (i.e. before it gets to the OS), and then startup - it goes through w/o a shutdown
- occasionally - and more frequently lately - shuts down during normal operation
- 2-5 hours into uptime, while seemingly doing nothing unusual - reading and browsing - shuts down abruptly
The system:
- Dual 2.4Ghz Xeon CPUs, 18GB RAM, 850W PSU, Quadro CX, boot SSD, four 2TB drives in RAID5
- Windows 10 Pro
