Why when my laptop's fan runs so hard and loud when playing a game and after 5 mins restarts itself?
551707
i have a presario 2500 and my fan runs hard on sertain oocasions. yours will be in overdrive due to the work the cpu is foing feeding the graphics card to run the game. What i do with mine is make sure its well ventilated underneath, either with a laptop stand, or a book so the famns underneath can intake as much air as possible and that the exhaust ducts are not blocked with dust or obstructed either. I have a stand with two cooling fans and mine works fine. As for the restarting, it could be a motherboard/power problem, or possibly you mighthave a virus.

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 had the same problem in my company, in my case it was a spyware/adware program.  Scan it with adaware http://www.lavasoftusa.com/software/adaware/\nand MS antispyware\nhttp://www.microsoft.com/athome/security/spyware/software/default.mspx\nthese to program will find it and remove it, if you have never ran an antispy ware program in this laptop you will probably find a lot of them, once you scan you pc and it asks what actions to take after the scan make sure you follow the software's recommendation.  If spyware/adware is not the problem your pc is probably overheating, a clear indication is  when the fan does not work.

Just check is there is something in the Fan went, even a small pice of dust can make a difference, You can try cleaning it up if you are confident about it or better take it to a PC Doctor or call the support.\n\nRegards,\nChethan

have you tried scanning the computer for viruses and spyware? that's one reason.\n\nAnother is possibly that the capacitors in your mother board are bloated. That happened to ours and my father just bought new ones that matched the bloated ones and soldered them in. Now our computer works again. \n\nOR try to see if your memory cards connection thingy( sorry forgot the term) are clean. \n\nOr the cpu fan ain't working properly.

A blocked or filthy fan reduces airflow across the board and processor. This can cause anything from minor system mis-behaviors, to complete crashes, to running for a time and then powering off. This also causes damage to the board, processor and hard drive.

Be careful.  Get fans around it.  Your going to need a new fan, it could be tomorrow or in a couple of months, but it is about to quit.  Until you can get a new fan, get a portable fan down there to cool your system down or you could end up with "melt down".  Good luck.

some laptops share the total ram with the video memory so maybe your laptop total has 512 ram but now is 448 because it share the other memory with the video card. and i don't think that the fan noise is related with this. hope will be useful, try  to enter to the configuration menu when the laptop is starting and look for the fact that i told you

Buggy RAM?  Was it all of a sudden?  Try running spyware tests.  Could be hidden programs task manager doesn't see.  You say you "sometimes" have the problem.  Any triggers that might set it off consistently?\n\nHave you considered reinstalling windows?  Might help.  Good luck.\n\n--An addition to Jerry's suggestion.  If the fan is kaput, the whole system will slow down.  I had a fan that was stuck from time to time.  Once I figured it out, my sys was back to normal.  Thank goodness I figured it out before the CPU fried.

Fan failure is quite common. Make sure it's just not a build up of dust first. Just do something before the CPU overheats and toasts your system. If you are still under warranty, and have on - site, tell them the fan is not blowing and they need to send someone out.\n\nIf it's not under warranty. Just replace the fan. It's pretty simple. If you don't know how, ask the person at your local TRUSTED office supply store to make a recommendation.\n\nIt's just a fan, don't let anyone give you a stupid price.

That could be a temperature issue. Make sure the air vents are clean and clear and that your fans are running.

Yeah...sounds like a shutdown virus has been downloaded onto your PC. But before you go that route, have you checked if the fan is running well? At times the fan may not be working so well, which may cause your PC to overheat and shut down. But if you do have a virus, you should just google 'Shutdown virus' and see if there are any anti-virus files available. Good luck!

It is possibly overheating. Check the fan. Check power supply, it could be going out. If not:\nYou probably need to reorder your BIOS by hitting del on startup. If you dont know how to do this please dont try, get help first.\nHere is a search of this problem, choose one of these forums that seems most similar to your system and ask them. They should be able to help. Its hard to troubleshoot a problem on Yahoo Answers as we cannot easily have continuous dialogue.\n\nGood Luck!\nhttp://www.google.com/search?hl=en&q=computer+restarting+over+and+over

if its making a loud whurrrrring sound, like a hum in way that means your air input fans and/or power unit fan are clogged with dirt and the fan is straining, causing the noise.\n\nif you have a fan on your processor as well, check it.

There may be several reasons why this would happen, I have a laptop and it does this when it heats up. I had a server running in my office which did this because of a bad hard disk. So the bottom line is you'll have to check for all the following: \n\n1. Heating Problem,\n2. Bad HDD,\n3. RAM Issues,\n4. Software Issues,\n5. Viruses.\n\nBy the way if you have done any new upgrades to the HW or software then that might also be a cause for such a problem.\n\nBest regards

Some possiblities are:\n-your fan is broken\n-or something else....since you've had it for six months you probably still have a warranty on it...get it checked out!

A noisy fan generally signals that the fan is getting near a failure point.  \n\nCleaning it can help, but as laptops are generally difficult/expensive to repair after a failure, I recommend taking it to a good computer shop.  A few dollars to fix a fan now is a lot better than a few more dollars to replace a CPU or the entire laptop.\n\nGood luck ...
