Windows 7 - My computer shuts down randomly.

Those are my temps .
CPU Digital Thermal Sensor:
CPU#0 Core0- min 24C , max 30C
CPU#0 Core1- min 24C , max 32C

ITE IT8720F:
Temperature 1: min 22C , max 22C
Temperature 3: min 175C max 182C

S.M.A.R.T:
SAMSUNG HD1035J Temp: min 25C , max 26

Ati GPU (ati radeon hd 5700)
GPU thermal diode min 40C , max 45C
GPU TSO(DispIO) : min 39C , max 42 C
GPU TS1(MemIO) : min 33C , max 39C
GPU TS2 (Shader): min 40C max 44,5C
And i have question what is that Temperature 3:min 175C max 182C always if that one gets over 210 it shuts my computer down and then back in.

Temp 3 has to be wrong. Thats almost twice the temp of boiling water

i am useing HWINFO program but always if this one gets high my comp shuts down

actually the shut down its quite random what should i do? maybe its not overheating but i dont know it always shuts me down while i am gameing and it sometimes shut down when i am just chilling around youtube. it even has shuted my computer down when it has been on for like 1 min

What temp does it show in BIOS? I suspect it's going to be high but not that high.

182C = 359.6F which is almost enough to melt solder.

Where i can see temps in bios??

u think that is overheating ? but why does it make shut downs before the windows starts almost always then when i am truning it on first time in day. Today i turned my comp on and it shut down and then it went back in and again shut down

IF i launch leage of legends its 100 % that it will shut down in 5-10min

You have to look around in BIOS Setup to find where the temperatures are show.

What is the make and model number of your computer. The users guide should tell you how to get into BIOS Setup. Also, there is usually some information on the screen when you boot that tells you what key you push to get there.

I think its not overheating because there is no dust and i have puted new thermal paste.

What you think and what is actually happening are not necessarily the same thing

I'd still recommend checking BIOS to see what temps it shows. It's often under Maintenance in the BIOS screens.

ok i solved the problem i just bought new power supply but i have new issue when i added the power supply now my monitor doesnt start . it turns into power saveing mode ( i think that means it gets connection?)
