Computer Turning Off Randomly.

April 18, 2018 at 02:12:08
Specs: Windows 7, I5 - 2400 / 8g of Unknown ram
My computer just turns off completely with no warning out of nowhere.

What i've noticed is that when my computer turns off and starts again, it has a higher chance of turning it self off again if i immediately open google chrome or games after the initial start up.

I though it might been my cpu temp but my cpu was cool to the touch [the heat sink that its].

I don't know if it its my power supply because my computer sometimes can stay on for upwards of 24h without turning off without warning. And sometimes i can play games for hours with out the pc turning off.

Any clues?

Pc specs for reference.
i5 - 2400
GeForce 210
GA-H61M-DS2 (mother board)
DSA-500ve (power supply)
8 gb of ram ( don't know the name )

could be dust buildup causing thermal shutdown, as i see you have a sandy bridge CPU thats 7 years old.

this is someone with a similar experience:

Could you run Realbench video encoding for me (3 runs) & tell me what temperature you hit?

Do no mouse the mouse or touch the keyboard, while running Realbench, it'll stop the bench.

if your temperature goes above 90, close the application & report back
if it doesnt shutdown by overheating, tell me your maximum temperature.
Should take about 5minutes to complete

You don't have to, blow it out.

I've ran 3 h.264 tests and my temps where hitting 99C max. and my pc didn't turn off while i was running the tests.

edit: and i blew the dust out of my psu.

damn that's really hot, its thermal throttling, is your CPU fan still spinning or did it die?
running a CPU above 80C isnt really good for its lifespan.

its either CPU heat sink is loose, thermal paste dried up, cpu fan and/or intake fan(s) stopped working.

most likely one of the fans died, could you investigate?

"i blew the dust out of my psu"

That's certainly a good thing but it will probably have no effect on your shutdown issue.

The Tcase spec for your CPU is 72.6C, so I think the 99C temp reading is probably in error. That doesn't mean the CPU isn't overheating, but I doubt it would run at all at that temp. What hardware monitoring program are you using?

BTW, thermal paste doesn't "dry up" but there are different types. Some stay more pliable (silver or silicone based pastes) while others are more dry (paraffin wax based pads).

Re #7 im talking about stock intel paste

I took off a pentium 4 heatsink last weekend, while trying to recover an old HDD, because it still had Win XP on it& im cheap ^_^.

But my point is the thermal paste had a lot of cracks in it, it wasnt rocksolid, but ill tell you that i couldnt re-spread it without it crumbling&creating air gaps.

Linus has a vid about it here:

I'm back, Thing is, i have my case open at all times, no my fan is not dead, my heatsink has no dust at all ( cleaned it recently ), i used realbench (#2 reply ↑ ).

I in fact know that my thermal paste is very sparse atm, after cleaning my cpu heatsink multiple times during the previous year, i believe that i may have almost completely removed my thermal paste (not on purpose). if that is the case than i'm in luck, as i will be buying a 1060, so i can buy some thermal paste with it. What's weird is that i can run games, videos and other media for long periods of time with out my computer turning off (as mentioned above), not just anygame... as you may have noticed my graphics card is old (which i'm only using till i get the 1060, my Radeon 7850 f---ed itself.), so i play mostly games that use tons of cpu. idk i'm just an amateur.

But thanks for the help, i will look into getting some thermal paste.

"i couldnt re-spread it without it crumbling&creating air gaps"

Thermal paste is not supposed to be reused. If you're physically removing the heatsink to clean it, all traces of the old paste should be completely removed from the top of the CPU & bottom of the heatsink. Both surfaces should then be wiped clean with alcohol or acetone & then fresh thermal paste applied. The application method varies depending on make/model of the CPU. In the case of a Core i5, the vertical line method should be used.

EDIT: once the top of the CPU & bottom of the heatsink are clean & wiped, they should NOT be touched. Fingerprints contain oil/dirt that can negatively affect thermal transfer.

Solved i guess, How do you close threads?
