Hi please bare with me as I am not the most technical sounding but I try to be thorough. I am not exactly a noob with computers neither. I have an issue where I will be on the computer and then suddenly the computer loses all power and reboots. The only indication I have that something is happening at first is that I hear all my fans in the case stop (just silence) and then the computer is off. Then my computer restarts and states that it did not shut down correctly the last time and asks how I would like to start back into Windows (Safemode or not).

The only thing I can think of is the latest change to my computer which was a few months ago (in May?). My friend Dave talked me into putting in a different Motherboard for minor improvement since he got it for free and wanted to gift it to me. However that might just be coincidence. But this issue did not start until after he put in the  Intel® Core™2 Quad CPU Q9550 @ 2.83GHz.

As far as I know that is all that has been changed recently.

No BSOD recorded in the last month or so.

Occurrence of the "power outage" was just yesterday.

My current specs & etc:
------------------
Processor Name: Intel® Core™2 Quad CPU Q9550 @ 2.83GHz
Processor Information: Intel64 Family 6 Model 23 Stepping 7
Number of Physical Cores: 4
Number of Logical Cores: 4
Installed System Memory: 4 GB
Operating System: Microsoft Windows 7 Professional 64-bit
Graphics Information: ATI Radeon HD 4850
System Product: BENICIA
System BIOS: 5.43
Case: ''OGRE Xtreme'' Nikao Case

My ex wonders if it might be the case is not right for this motherboard and is overheating or if the Power Supply is failing even though it is less than a year old and bought brand new.

The case looks like this:

What diagnostics should I run to figure out what is going on and what is wrong?

It could be a few things:

 

  • Powersupply might be going out and you may have to replace it. These will usually generate KernelPower errors in the event log
  • Capacitors (cylinders) on motherboard may be bad. Check them to see if they are bubbling/doming at the top
  • Possible issue with CPU, but this would usually result in a BSOD or Freezing to occur

:question:  Power supply seems fine. How can I test? It hasn't lost power in a month this time.

 

:thumbsup2:   Doesn't look like there is any bubbling on the motherboard.

 

:exclame:   CPU ... there is question about whether all my problems stem from going from a AMD CPU to a Intel CPU without a fresh install of Windows 7 64 bit. Could that be the cause?

 

:( Please advice what I should do to test power supply as well as if I should reinstall Windows and if that would fix the issues.

 

...........Even though I haven't had any more power outages I am still getting the freezing and the long response times and time outs in programs and games.. :smash:

 

:flame:  If the power offs were due to overheating there was an issue with the video card fan and that has been refixed so it is spinning again.

 

:graduate: Additionally I have ran Memtest 86+ v.5 for a few hours = no problems.

and I did a boot up scan (think it was chkdsk /f c:) for any corrupt files and it found none.

 

I also just did a sfc /scannow  and no issues:
