Windows 7: Sudden Power off

Thanks for that update, I was going to suggest replacing your motherboard, but you have already done that, so the problem is now most likely the Power Supply Unit. Replace it & see what happens.

It could also be a problem with you graphics card, but replacing the PSU would be the first place to start.

@westom Thanks for the information,very helpful.
The thing is the issue seems to disappear for some time (like days) then come back,but since the creation of this thread the PC shuts down every single time i run the game.

That would be the first thing I would try to resolve the issue.
Well that's the thing i can't borrow nor use my PSU on another system,the other thing is i bought the part from Sweden and currently I'm in Asia,so no way to return the part.

I would also suggest that you one again check all wire and harness routing.

The problem you had before could of caused damage that at times will show it's ugly head.

Sudden shutdown "Power supply surges detected during the previous...."

Something like this can cause problems to just about anything. Two things that come to mind are the power supply and motherboard.
Yes indeed.
Yes that sound's good,ill take it apart,and change all cables for that matter,you can call it the last stand before buying a new PSU .

Yes,sorry and thanks for reminding me about that.



So I'll be getting a new PSU soon,but before i do I'll consult you guys as always on which brand to get,thank you all !

There has been a breakthrough!
So my last move was to replace the cables before buying a new PSU,removed my Silverstone Sleeved cable Sets along with one of the VGA cables and voila it has been up for 4 hours and 45 minutes straight up with GTAV Firefox and many other applications at the background,so guess there's nothing wrong with the PSU ? i mean it being up for almost 5 hours without shutting down is a definite sign that this issue was related to the cables ? in other words are 5 consecutive hours enough to determine that the PSU is fine ?

That means something is 100% defective - constantly. And that defect can be identified (by numbers) at any time - both when a system is or is not working.

This concept is constantly demonstrated in the TV show CSI. "Follow the evidence." Observation is only equivalent to speculation. "Replace this" or "maybe try that" (as so many others have recommended) is also only wild speculation. Many have told you to keep replacing parts using shotgunning - using wild speculation. Throw dice to select what to replace next. Since that is what most are really doing. "Follow the evidence" means hard facts such as numbers. Described was how to get hard facts. Since hard facts did not exist before replacing anything, then nobody can say if a problem was fixed.

PSU is just as likely as cables, which are just as likely as a front panel switch, which is just as likely as a fan, which is ....

All that would have been identified or exonerated in a few minutes using a procedure that any layman or teenager can perform and that is required by an engineer.

So, has that latest 'shotgun' solved a problem? Another concept is also called "burn-in testing". Put a computer in a room at 100 degrees F (or use a hair dryer on highest heat setting to do something similar). Execute hardware diagnostics (unfortunately only better computer manufacturers provide these diagnostics for free). Or execute programs that activate many functions. Heat does not create defects or failures. Heat is a superb diagnostic tool to identify defects. Heat makes defective hardware create a failure - constantly. Failures that will also occur months or years later in a 70 degree room.

Heat finds defective hardware. But many want to cure heat - ie add more fans - rather than fix the defect. Due to shotgunning.

To be clear about this. 'Failure' and 'defect' are not similar. Defects can exist constantly. Failures are symptoms that might occur intermittently - maybe once every few days, or a few times at the end of every month, or only when the room is at 100 degrees F. Intermittent failure means hardware is defective at all times and will only get worse in months or years.

Did a cable solve anything? Since you did not see the defect before changing anything, then only wild speculation exists. We can only speculate that something was fixed. You could try a heat diagnostic to see a defect. If cable solved nothing, a defect may appear during that heat diagnostic. If a defect has been eliminated, then diagnostics (ie heat) can only say a defect 'might' have been corrected.

BTW test can never prove something is good. That is what statistics is for. 5 hours is only speculation that a defect has been removed. You have already seen how changes and defects over vary failure intervals. The question might be answered in 6 months.

Essential was to see a defect using hard facts BEFORE making any changes.

I'm basically looking for cable routing and neatness of how things are installed.
If things are not kept neat one can have problems with wires and harness getting shorted.

Examples of neatness:

That is neat,very nice setup.
