Computer shuts off without warning or restart.

[sketch22]

when i play minecraft for 20 minutes my whole computer just shuts off. no warning. no restart. just my whole system turns off , then my big white thing that all my power cords are connected to, turns back on but not the computer. its really annoying and makes me want to smash the computer to bits. anyone have a clue?

here are my Speedfan temps when playing the game and when not.

When idle (30% GPU fan speed) When on minecraft (30% GPU fan speed)

temp1: 72 temp1: 78
temp2: 42 temp2: same
temp3: -54 temp3: same
HD0: 39 HD0: same
GPU: 63 GPU: 74-79
core 0: 45 core 0: 50
core 1 : 43 core 1 : 45
core 2: 40 core 2 : 45
core 3: 40 core 3 :48

What exactly do you mean by "my big white thing"?

Change your Surge protector or make sure it is plugged all the way into wall is where I would start to look first.

 

[sketch22]

the big white thing is the "surge protector". because it has like 3 black cords pluged into it along with the router power cord.

try to bypass your surge protector and see what happens

 

[sketch22]

its plugged in all the way/

 

[sketch22]

how do you do that

Your symptoms are common to an overstressed and/or junk PSU. Please provide your system specifications, including the brand and model (not just wattage) of the PSU.

 

[sketch22]

its a dell studio XPS 435mt computer with a 475 watt Dell power supply. thats the most details i can find

 

[sketch22]

its the stock power supply for the 435mt

Stock Dell PSUs may not be junk (else they'd get killed on warranty claims), but they tend to be minimal. Did you upgrade the video card? What video card and CPU does it have? Any other upgrades?

 

[sketch22]

no upgrades. just bought it and thats it. it came with a ATI radeon HD 4850. made by ATI . it has a i7 bloomfield CPU 920 and 4GB of RAM.

How old is it? Perhaps age has taken its toll. I would suggest replacing the PSU. It may be wandering out of spec as it shuts off, and may damage your system. A quality 430W-500W PSU would be sufficient. Look for full range active PFC (no little voltage switch) and some level of 80+ certification for efficiency. Seasonic, Antec, Corsair, XFX, and Enermax/LEPA are among the better brands. NEW models by FSP (e.g. Aurum), NZXT (Hale) and Rosewill (Hive, Capstone) are also decent.

 

[sketch22]

thats not gonna happen. i was hoping on an answer that i dont have to spend money on accomplishing.

You might try severely underclocking the HD4850 to see if that brings power use down enough to keep it stable.
