Random Shutdowns??

[chooka]

So heres the deal,
i built a computer yesterday specs are

CPU - Pentium 4 S775-630 3.0Ghz 2M Cache EM64T
MOBO -http://www.cws.net.au/gigabyte/ga8s648fx775.htm
HDD - 120G Seagate 7200 ATA 100
OPTICAL - LG DVD Burner

I built the thing completly, put the Windows XP cd in......10 or 15 secs later the computer turns itself off? I have tried numerous times but it gets as far as the first Blue screen and thats it. Even if i try to enter BIOS, i can stay in there for about 15secs and then it will turn off?

I have never come across anything quite like it before? Can someone please help me...stressing out..

 

[chooka]

anyone have any ideas???????????????

you computer might be overheading, did u apply thermal paste under the CPU?

quickly go into bios and check ur CPU temps... if u can do it fast enought

 

[chooka]

Ok i was able to see the temp of the CPU....it was on like 96 deg! The Pentium 4's have a paste on the heat sink that is already applied. I tried re postioning the fan and heatsink, didnt work. I went into the BIOS and watched the deg go up.....started at 66deg and shut down after 15 secs when it hit 100deg....

stop using it until you can get another HSF and thermal compound, arctic silver of course would be best. if you keep trying to turn it on and temperatures are that high it could be permanently damaged. it could be a malfunction in the temp reader though because that seems way too high

 

[chooka]

Yeh i know it seems high?? As i was saying i have built many PC's with P4's and had no overheating problems??? Is the reading in Degrees Celcius or??

 

[Nitestick]

there is no way to be sure but i think all m/b's use celsius by default.

 

[chooka]

Ok then, dont you think it seems odd that it gained 35deg in like 15 secs?? Could it be the mobo reading it wrong...therefore shutting the system down??

 

[Nitestick]

yes it could be. the fact that the temp went up so quickly does not indicate this, that will happen if the heatsink or thermal compound isn't applied properly but nearly 100 degrees......f**k thats high.

i just phoned my dealer, and told him of the problem he said f**K!! thats high!. I sent the motherboard and CPU express post back to them!
