Hi, a few months ago i build my self a high end pc for mainly sim racing. I noticed that it would just randomly turn its self off and then on again. I might be wrong but this started to happen just after i installed the 2nd nvidia driver, after initially installing the very first one and even more so after the 3rd latest driver install. I did do a clean install from the nvidia site after the 3rd install but not sure about the 2nd.

Anyway i was wondering if this could be a software related problem like with the drivers. Most recently when i logged into iracing then try to play, the pc just turned its self off. It happened three times in a row like that. Sometimes it will turn off just after a minute of login into windows and that happens usually when the pc has been off for a while like 2 or 3 days "i presume". I removed and put back the memory and checked all the cabling and everything was properly attached like i thought. Once on the restart there was a "windows is trying to find a solution to the problem" or something like that....But well it didn't find the solution to the problem sadly lol. Any advice help would be appreciated tnx.

Update: I don't think its a Driver Problem anymore after doing clean windows 7 install but still get instant shut off...

MSi z87 g45 MB
i5 4670k (no OC)
Corsair 8gb 2x4 1600mhz
MSi gtx780ti 3gb GAMING GPU
Corsair h100i cooler
crucial 120gb SSD
Corsair cx750m PSU ( Looks to be the culprit ) - Now a hx1050 psu
Windows 7 Home Premium 64bit SP1 (OEM)

I would think this is PSU or mobo related as if its not heat it's normally power. Mine did this and I believed it was bad ram because memtest gave errors but it was the PSU giving bad voltages

I hope its the PSU and not mobo...that would be bad i guess. In action center maintance section just now windows was trying to fix or find a solution. Its said that i had video hardware errors and a shut down unexpectedly. Its just weird that it does this at such a random time. I would stream espn, play rfactor2 (which is very taxing on the cpu or system), youtube, netflix, would leave it running for the weekend, all kinds of stuff search the web and would do this all at a blistering speed smooth like jazz. Then i would shut down, turn it on the next time, and.......would turn off after about 20 sec lol after its nice and cool.

Update: No more Video Hardware Errors but still does shut down instantly

Did you get the problem fixed? Because I am having the same problem as you and don't know what to do.

After dealing with this issue for 2 weeks and going in and out of forums everywhere I finally just took it to best buy and did a hardware/software diagnosis ( bad idea!) . They didn't find anything wrong with it and it didn't turn off on them so I'm thinking its something related with my electrical outlets as my surge protector doesn't show that ground is working (if that's relevant). It has to be something with those outlets or I have a bad power cord for the psu....

I don't know if those geek squads did a really good job but my psu is finally doing these crazy noises and I don't thing its coil whine either. I speculate it started to go kinda bad after a couple months then really bad now with these noises giving it away.

I know I could have checked the damn thing before but was really hard to thing it was bad since it was new and is a corsair and in the MB if was up to specs with voltages and it kinda feels risky with that paper clip and everything.

Now I can't even play a simple game of chess titans without these noises coming from the psu every time i make a move. I thought I had coil whine coming from the gpu before at anything over 130 fps but rarely had the system shut down on me while playing a game any game. Now I thing it was the psu after all.

I listen closely to the psu while playing the most demanding game I have and it would do these screeching sounds at the menu, while playing and everywhere and shortly after that would shut down ( and its not the gpu ) that much I do know. I can almost feel when its going to shut down by the changes in noise.

I don't think so, I'm having the same problem as him and I have a 650W psu, and my specs are: GTX 770, i5 4670k and 8GB ram. 650 is more than enough for those specs.

You are right. I don't think they do thorough tests.

Yeah the the 750w is more then enough and even good for sli. I just think its too damn cheap of a psu for those higher end component's and now it's giving up and can't handle the load anyways. I mean why the hell would my pc turn off not even fully loading chess titans.......and those noises it makes are horrendous every time i make a move when it does load up. Just waiting for my gold series corsair psu to arrive in the next couple days and i hope to the lord i'm going to be good and get my money back from geek squad as well as rma the psu

Nice one!! I'll be just below you with an HX1050. Good enough for me and got it new with a good price off ebay. Really wanted to go with an HX/AX 860 but got 1050w for just about same price as those. I think it makes sense if you buy high end components might as well go for a high end psu......

When you worry you usually don't come up with problems its when you don't that you do lol........You should be fine. I mean in my case here if it really is the psu (which I have a damn good feeling it is) then you should be good with that top of the line ax series and upgrading should be smooth.

I forgot to update to this thread that I use to get BSOD's which was pertaining to drivers but now after doing a clean windows 7 install all I get is an instant shut down no blue screen no nothing and in event viewer i get that Critical Kernel Power Event 41 ( all codes zero ) which is most likely a faulty psu matter.

I also tried to roll back to older drivers, updated ssd's firmware, checked/reseated memory and gpu etc but nothing worked. Its just power related. Bad voltages low or high or whatever. I highly doubt its BIOS related either like with settings because never changed anything and if it was one would assume that these issues would have happened from day one........Highly doubt its ram either when it comes to this Kernel Power Event 41 because never came across anyone yet that solved it because of ram but have because of psu and going to investigate further. Ram problems is more of an overclocking thing i guess....

I had a similar issue last month

Started with when I turned my PC on it would instantly shut down before post screen and then 2 seconds later resume as normal... It did this for a couple months

Nothing I checked reported any errors... even the MB Self diagnostic array of lights on-board showed all ok.

Later the PC just shut itself down for no reason. First few times it did it like I had pressed the power button - exited out of programs games I was in the middle of and shut down in a civil manor.
At times when I had left it on overnight downloading stuff in the morning it was off... no errors msg on loading

Event logs showed no errors. except unexpected shutdown was appearing in logs now. rather annoying.

Swapped Keyboard, (in case of faulty sleep/pwr keys or something)
Check all pwr connections
Tested PSU in different Computer
Practically rebuilt the PC with same components checking everything
Scanned for Viruses/Malware
Did the usual updating of drivers and windows.
Monitored all temps - all below or well within spec

Then it started to get nasty with just instant power offs... And powering off during boot... It would also randomly turn it self on and off like it was totally possessed

Until it got to the stage of On/Off every few seconds the just off, that the PC was unusable

High End "Ultra Durable Gigabyte Motherboard" a few months out of warranty. Appears that the American Power management chip on this MB had like 6 different power Blah blah ipod charge redundant this that saftey yarda gibba jabber technology rubbish - the management chip had decided to fail.

Ultra Durable My F@#K!^& @)$3

So I hope your symptoms do not follow the above model...

I sure hope not......"Ultra Durable My F@#K!^&@)$3..........lmaol. Did you manage to replace the chip or had to replace the whole MB? Hope not the MB.......About a week ago I installed an Intel Power Management Driver that had a Hotfix included from the MSi website hoping to solve this issue but nope.

I always had this power management thing in the back of my mind just because it says "Power" management because it sure as hell sounds like a power management issue. Whether PSU or some BS chip.

I always had it instant turn off after login at idle after about 30sec to a min (usually the case - lot less when gaming or other although not the case now).....only 2 times at login during the 20+ times it did in the past 3 1/2 weeks but never in bios.

Before when i had those BSOD's when i checked in action center "Video Hardware Error" would come up but now when i check nothing shows up.

Having only basic soldering skills and no idea where to get a compatible replacement didn't even try to bother with that. (considering some motherboards have up to 7 layers of circuity in the pbc board the chances of breaking something else in the process of fixing it is a potential issue.

Just my luck the 1156 Socket MB are as scarce as hens teeth so it was new MB and CPU ;(
Goodbye i7 and hello i5 (due to current budget)

Maybe there is an option in bios to disable the power management system, or a Bios Update that fixes it or allows you to bypass it... Due to failure of this chip that was not an option for me to test or try...

Hmm may google and see if there is a possibility of disabling the chip manually of by hardware bypass - very unlikely

Update: Futile attempts to find further info on my old issue or your Current issue have failed dismally

Maybe someone else can offer suggestion to help shed light on tips and tricks on Power management systems and how to avoid integrated MB's that use them? Or...

I hear you....

New MB......AND CPU?? Damn!!.....So had to ditch the i7 for i5? What it wouldn't fit in the new MB?

Yeah no Sh*t I hear you on the bios update!!! Always considered updating bios but......:no:

I think i have it disabled in the bios but not sure. Would be nice to do so otherwise. Anyways sorry you had to go thru all of that BS man......Your scaring me also :ouch:

Yeah... Cause "This issue occurs because Power Manager opens an Advanced local procedure call (ALPC) port. However, Power Manager closes another port instead of closing the ALPC port. Every time that a power request is made, a memory leak occurs. When the leaked memory usage accumulates to a certain level, the computer crashes."

If your issues only happen in windows or when it logging into windows IE Software issues with Hardware then this could be good news for you.

Yeah I used to get that Video Hardware Error BCCode A when checking in solution in action center after BSOD and would get different code # in those 4 parameters. In BSOD would get that IRQL_NOT_LESS_OR_EQUAL_TO which relates to drivers.

I could swear I also saw once my graphics card name pop up after solutions - Don't know how it managed to show up but it did only once..........scares the sh*t out of me but none the less I'm still guessing hardware errors could show up because of faulty PSU or perhaps PMC.........It has to be true because have no heat issues or anything with gpu and at that time would play for hours iracing/rfactor and never shut down instant or BSOD - only at idle after cold boot usually or when web browsing occasionally.

Now would instant shut down ( no BSOD ) while playing chess titans and PSU making these weird noises.
