computer restart?

Question

i had a computer, PentiumD 915, 2.8G, on a MSI 7255 board. Ram is 1.5G 667Mhz. Sata running on 80G HDD. 2 casing fans connected thru power supply pins.
my problem is the computer restarted after about a few hours operating. I had reformat it and install new Windows XP, but the problem is still there. Can anybody help? The CPU uses teh supplied cooling fan came with the box. I'm afraid the problem might be caused by inadequate CPU cooling or insufficient power supply. Anyone please help..

Answer 1

make sure you have an adequate power strip (surge protector) for starters. Nothing less than 2000 Joules. After that I would make sure your power supply is b/w 300 and 400W.

If you have taken care of those two things and you still have a problem, make sure the processor is stayong cool. Make sure there isn't any excess wire wraped around it. Also make sure you clean the dust inside your computer every month or two.

Answer 2

Download SpeedFan, available as freeware on the net. Watch the cpu temp and watch it over time to see if it keeps rising before you get a shutdown. You may need some good thermal paste on that cpu, since the D processors really heat up. Also check your bios settings to see if it it is set to shut down if temp is in that region.
If SpeedFan, has a handle on your motherboard sensors, you can also use it to drive your fans independent of what your motherboard does using the bios for better cooling .Experiment.

Answer 3

If you feel that the CPU has adequate cooling, you may have a broken sensor. (The computer THINKS that it is getting too hot due to a faulty sensor). Most likely though, it is not adequately cooled. You can test this by opening up the computer and blowing a fan through it. If you problem remains, you may have a faulty sensor. If not, get some new fans. Hope this Helps.

Answer 4

Don't do what the above answer says. It is due to inadequate cooling, but you installed ACPI with your Windows XP OS and that is what has saved your computer. Windows detected that your hardware was getting too hot, and shut it down. Buy a new coolant and that should fix your problem.

Answer 5

The advice about SpeedFan is good. I use it myself.
However, I'd check the BIOS to see what your CPU temp is and what the shutdown temp is set to.
Check the motherboard manual or just go into your BIOS to hardware monitor (or something like that).
Check the link for your motherboard manual.

Answer 8

it very well could be the cpu temp. the pentium d's in general run hot. you can download speedfan (free) http://www.almico.com/speedfan.php

and it'll show you your system temps

and if it's running pretty hot (57*C+) i would look into a new cpu fan/heatsink. i assume your 915 is a LGA775 socket, and this is a great fan. it lowered my temps almost 20*C

Answer 9

Install Core Temp so you could monitor processor temp down to per core level.

Also consider cooling solutions from Thermalright, Scythe, Noctua, Zalman, Thermaltake, Coolermaster, etc.

Sounds like the Power Supply is too small. Change it soon or you could damage your Motherbord and CPU, I see this happen all the time. It's happened to me too. Don't even turn ot on again, until you change power suppiles.
