computer running hot

my computer is running at 150 degrees F, and the MB is at 100 degrees. it has been restarting unexpectedly and i suspect this is the problem. should i get another fan and move the computer to a more open space? my monitor also goes into standby and doesnt come back on unless i restart so i guess it could be causing that.

:wtf: Power fluctuations? Have you had a hardware professional check out the voltage and speeds? Have you had all your cooling equipment thoroughly tested? Is the case properly ventilated?

Not normal temps.

Try disabling your system's power-saving modes to NOT place the hard-disk on standby/hibernate and the same for your monitor.

Assmuing you have at least six inches of space behind your PC's exhaust fan, when was the last time you opened up the PC case and removed the dust coating the components? Clean out the intake and exhaust vents of the case/power supply while you're at it.

have you cleaned the inside of your pc? dust can be a real biatch...check to make sure your fans are turning properly...both the cpu fans and the power supply fans, its been known for them to die out and not warn you...most pcs have voltage and heat protection settings that reboot them or shut them off....your memory could be toast too from the heat....anyways check your fans and break out the compressed air...add a fan for the back of the pc as well if it has a spot (80mm case fan with 4 pin connector)

If you only have on or two fans, your computer is probably not getting proper ventilation. Also, always have more intake fans then exhaust. Do you have a stock case or a aftermarket one? If the computer keeps shutting off and/or restarting, its very possible that the tempatures are causing this. May I suggest going to www.xoxide.com and buying some fans. The cheapos will work fine, but they will be very loud. I got some "cooler master" 80mm case fans and they work pretty good. Oh, another thing. If you trust yourelf to drill&tap some holes in your case, you can move up to 120mm case fans.

Could be a bad motherboard. Might also be as the others' suggested. Clean the dust off, disable power saving options, check your BIOS settings to make sure they are set properly, and see that the case is properly ventilated. Do you have any overclocking features on your board? If so, make sure they're disabled or the hardware is set to OEM specs and not overclocked.

Also, if you have Windows XP it might be a bad installation. Windows XP will sometimes restart randomly if there's a driver conflict or if it's just a bad install. The PC will also restart randomly if it's too hot or there's electrical power issues.

Actually, it's better to have more exhaust than intake. I found this out myself. I noticed the temperature of a machine I worked on went up when I added fans in the front. So I ended up removing them. It's actually best to have exhaust only and let the air come in naturally. If you try to push air into the system, it creates turbulance and basically turns your computer into a convectional oven. A very efficiant cooling system will have an exhaust fan, power supply fan, and an air duct over the CPU fan that attaches to the side panel. Also, the bigger the fans, the lower the noise, and the better the system will cool.

BTW, what chip are you running? The AMD Barton and the Intel Prescott cores do run pretty hot. Intel says you're safe as long as you're below 70 degrees Celcius. If you have a stock heatsink and fan, you can upgrade that to a bigger heatsink made out of copper.

I worked with Marine colonel (Ret.) who was in Kuwait the first time (less than a klick from the Iraq border), mostly under the sand in containerized setups for their payroll computer systems. The first couple of weeks of ops found PCs crashing one after the other. On opening the cases, they found them contaminated with fine sand.

Some genius decided to reverse the direction of the exhaust fan in the PS, jury-rigged coffee filter paper as an air filter to the PS now intaking air, and lo-and-behold, solved the problem. They "field upgraded" all of their equipment that had exhaust fans to the same set up and added additional fans to those that needed more air flow (restricted by the filter setup). It's called "positive pressure" and as long as the intake air is filtered sufficiently (and there is enough air flow to cool the components), no dust/sand can come into the case. Been working for me these past 10 years.

Filters for case fans what a novel idea. Look how this guy took it a step past coffee filters :)
