Hi. I have a MSI GT780DXR laptop which is a couple years old now (out of warranty) and I have been experiencing some random reboots since relocating from Canada to New Zealand. I initially thought that it might be either an overheating issue or perhaps an issue with the voltage change putting additional strain on the AC adapter since I had never had this issue in North America.
System specs:
Windows 7 Home Premium 64bit
Intel(R) Core(TM) i7-2670QM CPU @ 2.20GHz
16GB DDR3 (4x4GB)
Nvidia Geforce GTX570M
2x500GB 7200RPM Striped RAID
Things I have done:
Took the laptop apart and cleaned and reapplied thermal paste to the CPU and GPU; cleaned any dust. My temperatures are stable and under 85C for the GPU and 75C for the CPU while performing stress tests and under 50C while idling.
Tested the AC adapter which is outputting a stable 19.5V.
Reformatted/reinstalled windows and tried a number of different nvidia graphics drivers, all with the same result. Also updated windows and installed the latest drivers for everything.
Ran memtest - everything came back OK
Flashed the BIOS.
Ran chkdisk - everything came back OK
Ran driver verification.
Ran furmark, OCCT, and prime95 stress tests - again, temperatures are stable. FPS are stable.
Ran IntelBurnTest - Everything fine. Gflops are between 48 and 54, which appears to be normal for my version of the i7.
Additional observations:
It does not reboot while on battery power -- only when the adapter is plugged in.
When it shuts down, there is no warning. No error log in the Event Viewer (other than the standard "you had an unexpected shutdown" type message) It is as if the power was just turned off.
Stress tests seem to run fine. Generally it shuts down shortly after I end the stress test or following heavy GPU/CPU loads but seldom/never during.
It can go all day without shutting down, but once it starts rebooting, it generally will reboot several times in a row. If I leave it overnight, it is generally good for several hours after I first boot it up.
If I drain the battery, the reboots happen much more frequently. It also happens more frequently if the battery is removed (even if I am not running any sort of stress test or gaming)
This problem happens regardless of whether or not I am overclocked.
Any further advice would be appreciated.
