Built a new desktop about a month or so ago. Everything was fine until a couple days ago. I came home and was told the computer was shutting down randomly after about 15 minutes of use. I immediatly began troubleshooting, starting with recreating the incident, then going into safe mode and running low level diagnostics. Before I go any further, Ill go ahead and describe my setup.
mobo: MSI NF750-G55
RAM: 2x4GB Kingston /hyperX
HDD: Seagate 750GB Barracuda
CPU: AMD Phenom 2 am3 socket 3.2Ghz
Tower: Rosewell (the one with 7 fans/leds and 80% mesh) forgot the model # lol
PSU: Corsair 650watt bronze star certified
Graphics: Nvidea GT240
OS: Windows 7 home premium
So now thats out of the way, onto my annoying little problem.
The computer shuts down when:
after loging into windows, when windows is loading
when booting to safe mode (any type of safe mode)
when running sys restore
when booting off windows 7 repair disk
It first started shutting down only when u log in. Now it has progressively gotten worse and will not boot in safe mode at all. I also attempted to boot from Hirens on my dvd drive, and it does nothing.
I have taken the following troubleshooting steps with no success:
Run chkdsk (it shuts down during step 5/5
Run sys restore (shuts down in the beginning)
Try with 1 stick of RAM
Removed Video card and used mobo graphics slot (HDMI)
Strip down mobo to bare, reseated CPU, cleaned and reseated heatsink.
Tried a clean install of windows 7 (shuts down during install and fails)
Nothing new was added or downloaded before this happened. It worked just fine, all system temps were fine and no errors before. I am out of ideas and need other input before I determine for some odd reason the dvd and hdd drives are bad and replace them. Thanks for any and all help with this.
