Windows 7: All new Hardware Custom build Freezes requiring hard reboot

All new Hardware Custom build Freezes requiring hard reboot

Hey guys, I have a PC that was custom built with all new hardware, and I'm getting hard freezes anywhere from once a day to once a month.
It happens while doing anything from watching a movie, to just browsing the web.

I replaced the PSU, flashed the Bios, reinstalled windows, changed the power settings, updated drivers but the problem still occurs.

Windows event viewer doesn't show anything that related to the crash except "previous system shutdown was unexpected".

I ran a stress and cpu test as well memtest all of those came up fine.
Since all the hardware is new not sure what to switch out first, or if I should reinstall windows again or change something in the bios.


I'm using a
Intel i7 3770k,
Intel graphics 4000,
Asus H61M-A Motherboard,
1 Crucial DDR3 Ram 8GB
Samsung Evo 840 SSD as primary drive,
Seagate 1TB HDD
Corsair 550 watt PSU

Any help is appreciated.

Hello Avaava mate now you say you have swapped out most of the components just exactly have you not swapped out? I am assuming the board is new in which case (no pun) may have an issue.

Now just out of my curiosity could you do this as the PSU bought new might not be right and it would really eliminate for good that source of any problem.

Using HW Info
PART A:
You can test the volts on the PSU with HW Info HWiNFO, HWiNFO32/64 - Download < download the right bit version and close the right hand window select Sensors and scroll down to the power section where you will see what the volts are doing see my pic. In my pic the section (Nuvoton) with VBATT is a dead give away you are in the section for the rail voltages. There are other section titles and one that pops up often is ITE
Now the voltage on the different rails have to be within 5% =+/- of what is required or the machine will not work properly if at all.
See this for the rail voltage info
http://www.tomshardware.com/reviews/power-supply-specifications-atx-reference,3061.html (Section 2.)
The original right hand window shows the machine running and is handy for that but for looking at the components in some detail close it and use the main left hand side panel
FOR OTHER COMPONENTS
PART B:
Open each small square with + in it on the section the components are in and then click on the individual component/s (it will highlight in blue) - in the right hand side will appear all sorts of details including brands speeds and other essential info that particular device. See pic for example.
Use PART A: for the PSU (the pic is of my main deskie - Asus Ivy Bridge board so am guessing the section you will see will be Nuvoton) should you want to know the very fine detail of other stuff use PART B:

Hey ICIT2LOL, I'm not sure what you mean I took a screenshot of my voltage.

Yes well the second shot you sent the motherboard volts are showing up in that Asus (Nuvoton) section the one with the Vbat in it. However I can only see the Vbat (CMOS battery) and 3.3v rails which seem to be ok but the 5v and 12v is not there so cannot comment on them.
As you can see in my pic of my own board they are clearly marked and unless the HW Info has been modified I don't know why the volts are not showing up.

It is important as you can see that the volts are within +/- 5%of the stated value because that can cause failure ie < 5% then devices will not function or badly and > 5% it can cause damage. Having said that you can also read in that link that the PSU in particular has a built in safety circuitry that will not let the machine even power up unless the voltage is spot on.

The other alternative for you to test the volts for 12v and 5v rails is to do it manually with a digital multimeter (very cheap to buy and see pic) and measure them at the 24 pin plug to the motherboard see this for the voltage references.
https://en.wikipedia.org/wiki/Power_...unit_(computer) scroll down to the colour chart and use the black lead from the meter to any black terminal and the red lead to test the positive volts.

Now I am only asking because the PSU is commonly the cause of a lot of computer problems than some give credit to, and with good reason because no or incorrect power and the machine does not function.
