Newly built PC resets itself

Hi,

Hope you can help.

I have recently built myself a PC (Windows 7, i5) and it's running fine except for one problem. Every now and again, when I've been away from it, I find that it's reset itself. I don't think it's overheating as the machine has two extra case fans and the temps seem fine.

How should I go about starting to investigate this as it has never reset itself while I've been there.

Regards,

C h r e d g e.

 

First thing to do is check the event logs. That would give you an idea of what could be causing the rebooting.

 

turn off the auto reboot
control panel /system/advanced/startup and recovery settings
then untick the auto reboot box
post any bsod error messages the computer freezes on in full

what are you running
video card brand and model
cpu
m/board
ram
power supply
brand
model
wattage

check the listings in the bios for 12v line voltages and temperatures and post them

 

Hi,

Thanks for your help guys.

Some info for you.

GPU - Radeon 7870
CPU - Intel i5 3470
MOBO - MSI Z77A-G41 Intel Z77 Socket 1155 DDR3
RAM - 2x8GB Mushkin Enhanced BlackLine Frostbyte
PSU - 500W Corsair Builder Series 500CX 80PLUS Bronze Power Supply

*In the event logs, what is it that I'm looking for? This is ticked in the advanced settings so I imagine there would be something there?

Thanks again,

C h r e d g e.

 

your min psu needs to be here

http://www.newegg.com/Product/Product.aspx?Item=N82E16817139005

would prefer to see a 750w in it and only corsair hx.tx.ax models

 

As for event log, check for items with a red X, with an "Info" entry near it stating that the last event log entry was stopped unexpectedly (or something similar to that).

 

Hi,

Thanks again for your continued help.

Having found/checked the event logger I have discovered a number of 'warnings', 'errors' and 'criticals'

Warnings are (mostly) - DNS Client Events
Errors come in various 'flavours' - Service Control Manager/BugCheck/Schannel/
Critical was all - Kernel-Power

Each of these types comes with a short description of what the problem was, how do I actually resolve all these?

Thanks again,

Check the "Kernel Power" entries, and there should be an Event ID, and a Source. Post that information here, or a screenshot, and this should help out.

 

Hi,
Thanks for your help, here is some info for you;
This problem has been discovered while initially investigating why my PC was occasionally shutting down on its own. The PC would be left for some time and when I’d come back the PC was off. This is a new PC which I put together myself, there didn’t seem a specific time when this ‘shutting down’ problem began. After asking on other forums some people speculated that the problem may be connected with the PC going to sleep (I was having another issue whereby the PC would go to sleep by I was never able to ‘wake’ it).

Windows 7 – service pack 1
GPU - Radeon 7870
Processor - Intel i5 3470
CPU – 3.20GHz
MOBO - MSI Z77A-G41 Intel Z77 Socket 1155 DDR3
RAM - 2x8GB Mushkin Enhanced BlackLine Frostbyte
PSU - 500W Corsair Builder Series 500CX 80PLUS Bronze Power Supply
500GB HDD

tx.hx.ax.axi

yours as well as underpowered is one of their low quality units

 

Is the system creating any dump file? C:\Windows\minidump If so, please copy minidump to the desktop, compress it and upload it here.
