+3.3V going haywire

[Doc.Pock]

well moms PC kinda started just turning off after a few minutes of work. then we had to move it to a diffrent room for some reasons and it was all ok. today i start it in its old position and it shuts down after 4 minutes. i have since tried a diffrent wall plug (how do you say that in english) and have opened the PC completley thinking it might be overheating. it made the PC work if i dont do any serious tasks but the 3.3V is going quite high to 3.6-7V but it works.

i havent OC the PC ever and it worked just fine when it was in a diffrent room.
any ideas what it is? thnx

a intel desktop utilities log relevant today and yesterday

THis is a desktop or a notebook?

There is no safe way to fix a dying PSU.

You'll have to replace it.

Easy enough on a desktop, takes some research to replace it on a notebook.

[Doc.Pock]

its a desktop.

but why would a PSU stop working then when moved start working again and now when moved back stop working again. it all seems weird for me. also what is powered by 3.3V anyway?

maybe your voltage is messed up on that outlet
try checking the voltage

or
1 you get a really long extension power cord and
2 plug it in to the room that works
3 now move the cord all the way down to that other room.
4 plug the computer in to the cord
5 problem solved?

[LITOralis.nMd]

lol rushn.

Doc.Pock, it could be the electrical wiring in your house walls. Could also be the capacitors in the PSU are being discharged when you unplug it, so by the time you moved it to other room, the capacitors had no charge and are back inside their degraded abilities.

[MaSSive]

Seriously those temps are sky high for desktop CPU and voltages are also very high, thats probably causing overheating and shutdowns.

If you can get a spare PSU just for test, try and see how it works. Best bet is that its PSU. But might be mainboard dying too, which is a bigger problem then. But if you dont do something real quick, one day it will shut down and it wont start at all, ever.

So be quick.

Also your answer would be almost everything on 3.3V?

Standard Output Voltages

Seriously those temps are sky high for desktop CPU and voltages are also very high, thats probably causing overheating and shutdowns.

With my old PC I suffered from overheating from inadequate airflow. If possible, buy a case fan. Temps in the upper 90s usually cause automatic shutdowns so this may be your problem.

You can probably pick up a PSU-case combo cheap which would solve both problems.

[Doc.Pock]

It is fixed now not sure how but it is. And massive. It couldnt be mb cuz its new. And dooes anyone know what is powered by 3.3v?

Don't make me laugh. Ive seen DOA mobo's and fried after few days also, failed after few month etc. If its under warranty all good. Better to die now then later when it expires.

SO what was the problem? Forgot to plug in cpu cooler? Thermal paste? 92C for CPU and those voltages cant be normal, and it wont go away just like that. At least I never seen it go in that way, and I have mileage like you years

[Doc.Pock]

Dont look the cpu temp that is old as shit. At that time the fan was being blocked by soke shit and i failed to figure it out fast. No problems from ti thou.

[MaSSive]

Oh so now its old shite. Mkay...so dust was the problem...mmm..heat increases resistance, which increased load and currency, and bumped voltages up. Simple Om law.



*P = Power
*U = Voltage
*R = Resistance
*I = Current

maybe the PSU got overheat and fried a little

f t just started workng again I would be concerned and if I were you I would ether get t checked or send it back for a replacement
