What happens when you run it in safe mode? Anything in the event logs stand out?
Hard to say re. safe mode because it potentially takes so long to crash. We need to use the PC daily and can't leave it for long enough, and don't really want to leave it unsupervised overnight as when it crashes it doesn't seem to restart, it just kinda ... freezes and becomes un-usable. Although I think once it did reset.
The event log is full of Critical number 41 as you'd expect however there was one critical log that stood out, which was:
Task Scheduler service has encountered RPC initialization error in “RpcServerUseProtseq:ncacn_ip_tcp”. Additional Data: Error Value: 14.
Really not sure what this is, and it was only logged once (could have been the time it reset). My girlfriend logged the times of every time it restarted and we stopped counting at 15, over the course of 1 day/night.
In regards to "Error" entries in the logs, there's about 100 of them in the last few days, many of them are different.
There are a bunch of "Machine Hardware Errors" with the content: "Reported by: Processor Core. Source: Machine Check Exception. Error Type: Cache Hierarchy Error. Processor APC ID: 2 (sometimes 3)".
Also 2 more that stand out are:
- Event 7001:The Network Location Awareness service depends on the DHCP Client service which failed to start because of the following error: The dependency service or group failed to start.
- DCOM got error "1084" attempting to start the service WSearch with arguments "Unavailable" in order to run the server:
Almost as if it thinks we're running server 2008, no?
I am going to bed now so will reply to anything else when I get back online. Thanks!
Hmm... Put your other processor back in and run Memtest86+ - Advanced Memory Diagnostic Tool to rule out a RAM problem then smack it with GIMPS - Free Prime95 software downloads - PrimeNet small FFT and FurMark: VGA Stress Test, Graphics Card and GPU Stability Test, Burn-in Test, OpenGL Benchmark and GPU Temperature | oZo… mainly to rule out a power supply issue.
Try, entering the BIOS to increase the voltage of the RAM modules @ 1.65v (although they give to 1.5v).
After removing 1 of the RAM sticks, the PC has run for a steady 24 hours without crashing. Calling the seller back now to discuss this further as it indicates a fault in the CPU.
We're also out of thermal paste so can't put the old one back in just yet - should have some more in a couple of days but for now it's working (albeit laggy because I think all the crashes have taken a toll on the CPU - everything, even videos are lagging and were before we removed the RAM)
Will see what they advise me and post here.
