Power Supply overheating?

yes get a new one.. newegg.com has some that are really inexpensive.. 15-20 bucks. I recommend the Hipro brand. If you want to spend more they have top end psu's also.

overheating is caused by your CPU running for long periods of time without adequate cooling. It should be fine.

This sounds like an overheating problem, you did use heatsink compound, right! Did you reinstall O/S after swapping motherboard?

The power supply might have gone out.

If you're using a laptop, your battery is probably dying or the cooling fan isn't working properly. You'll need to take it to a shop to get it cleaned properly - don't pop the case open yourself.\n\nIf you're on a desktop, you're probably overheating, either the power supply or the CPU. You need to open the case and blow out all the dust, especially around the CPU and fans, and make sure your fans are running properly, especially on your power supply.

I have seen this problem with motherboard that had the capacitors across the power supply inputs go bad. Other possibilities are overheated processor, overloaded power supply, & misconfigured power schemes.

This a typical behavior of a computer that is overheating the CPU try checking the cooling fan and if it looks defective replace it immediately b-fore it causes more damage, the Power supply also will cause this to happen but this is more complicated than just replacing the cooling fan. A faulty keyboard an a defective mouse will also provoke this ugly and unkind failure.

Maybe your power supply just failed or something isnt snuggly plugged in. It could be that something got caught in the fan and it shut down from over heat automatically

Sounds like you bonked something opening it up and the power supply got messed up. I was trying to work on an old Gateway and the motherboard started to smoke :0, guess some computers weren't made to open up.

Could be the cooling fan or the hard drive. Check both.

it could be the power supply, you may want to take it to a pro

Two most likely culprits:\n\nPower & Heat. \n\nFirst clean out your computer. Get rid of the dust, clean off the fans. \n\nIf that doesn't work buy additional system fans.\n\nIf that doesn't work replace your power supply with a larger wattage one.

Check the fans and make sure they ALL are working. If you have a CPU temp utility, use it. Try starting in safe mode and see if it is still happening.

Your computer could have been heated too much.Try working on it after shutting down your pc for an hour or two.

acrtoss the power supply

The temperature inside yourt computer is too hot, pls check your internal fans if they are working properly. This is bad and you can damage your processor permanently.

I'll try to return the favor of answering your q...\n\nI have a couple of decades of hardware experience, and your problem is one of the more difficult to pin down quickly. It's possible you have power supply problems (your electrical system). If the voltage dips "too far" (how far is too far depends on the electrical device) then your Compaq may shut down. Different computers, even different Compaqs, may shut down more, or less easily as the voltage coming from your wall outlet sags below 120 volts. You may, or may not, notice the lights dimming, but it may still be enough to trip the off circuit in your Compaq. If you don't have one yet, spend $40+ and get a battery backup (UPS). It'll help any system last longer, too. I like the APC UPSs.\n\nSecond possibility is that your Compaqs power supply (internal silver box) may be getting flakey. I haven't worked on a Compaq in a long time, but they used to have "custom" (proprietary) power supplies that required going back to them (Compaq) for a replacement (at a premium price). If it's a standard size/shape, then a new power supply is only around $50 to $60 and available at most local PC stores. Not a lot of expense, and easy to replace for even a novice. (Please uplug the system from the wall first, and try not to touch any electronic components inside the computer during your foray into the inner-world of your Compaq.)\n\nIf you still have trouble after confirming your electrical supply is good and your power supply isn't causing the shutdown, it is -slightly- possible you have a bad hard drive or mainboard. Replacing either of these is doable, but not for the non-tech. If you have a spare hard drive, you can just install it (replace your current hard drive) and fire the system up...let it sit...if it runs for a substantial amount of time longer than it usually does, then you -might- have found the problem. \n\nFinally, you may just have a heat problem. Try making sure all the vents (front, side, back) are clean and clear of obstruction. If you feel competent, take the case cover off and blow out the dust inside (but take the system OUTside first!). I've seen systems in relatively clean office environments build up a half-inch of grey fuzzy 'lint' all over the inside in less than a year. Even if this doesn't fix your problem, it'll probably make your system last longer by running cooler. I've seen hard drives that ran as low as 90 degrees F, and as high as 175 degrees F. The lower the better...within reason (less than 120F should be fine).\n\nHope this helps.
