To replace a modem in a computer is incredibly easy, but it depends on you. A good replacement modem is only $20 to $30 dollars, and in most cases to replace it in your tower consists of removing some screws. It would depend on your expertise in using tools, though (like a screwdriver). Just research it a little bit, take your time, and you should have no problem. Good luck

Switch of the power to your modem and leave for 5 Min's, then switch back on and leave for another 5 Min's, that might do it.\nAlso check your security settings.\n\nHope that helps.\n\nGood Luck.

On the bottom of the modem is a ip link. Use the serial number etc Type it in and go to the site..Don't login but do the necessary tests. See if that cures it. If not call sbc.

the fact that it was next morning suggests to me that it's not overheating. if a fan stops working it will not stop computer booting up, i think the sound may be your hard drive maybe. have you got access to another hard drive you could stick in and try? or a computer you could try yours in just to check if it boots. diagnosis is the key here!!!!

Good information to help you resolve this would be:  new or used computer?  It could be shutting down for a multitude of reasons...  The first to come to mind is temperature.  Most motherboards shut down a few degrees before the processor's thermal breakdown point.  You may want to see that your heatsink is seated on the processor properly, and that any and all fans are functioning.\n\nAnother common culprit would be a virus.  Look for a free program that will let you do a boot time scan of your system.

Are you overclocking it? if so, stop. If not, check to make sure the fan is functioning properly. If it's not, and it's still under warranty, contact dell and get em to fix it. If it's not under warranty, a quick solution is to have a large fan blowing on it. Then, consider replacing the fan entirely.

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!

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.

I had a similar problem caused by an overworked power supply unit (PSU) which was cheap to replace, but in reality it's not going to be possible to diagnose over the internet as it could be any one of a number of hardware or software issues.\n\nMy advice would be to call some independent PC repairers. Some offer a no fix no fee service & should tell you up front what the cost is likely to be.

If your power supply is faulty or your processor fan is broke your PC will shut down to cool down, but wouldn't necessarily start up again.\nIt sounds like a virus or worm infection.  I would try going into windows in safe mode (F8 function key normally) and see if the system continues to close down.\nIf it is stays on o.k. check you haven't installed a driver or software recently that may be conflicting with Windows.  If this happens you should be able to roll back the driver or system restore to a point where you know your PC was o.k. (In F8 this is the "Last known good configuration")\nIf it shuts down again it may be a virus, have a look on symantec's site for a hotfix for the latest virus/worm,if it is a virus you'll proably need to disable your system restore whilst trying to remove it.  Follow the instructions to remove it carefully so not to destroy your pc further!!

if you must, take any other three wire fan plug and plug it into the cpu 1 connector on the motherboard.....but again, you WILL DESTROY your Processor! if that doesn't work, or you don't have another fan present in the case, go into the bios and disable halt on all errors.

Sounds like a problem on the motherboard, but it's hard to tell. It could also be one of the voltages from the power supply is missing. Power supplies are usually $40 to $75 bucks if you want to give it a try. You're better off taking it to an expert, though.

I would start by changing out the power box. Open the computer and smell the power box to see if it smells burned. You can purchase a new one for under $50.00. When you have a surge, with or without a protector, your power supply will go first. If it doesn't not want to boot up, this means there is insufficient power to allow the computer to boot.\n\nYou can change this out yourself, with the help of some Internet instructions and about a 30 minutes of time. Good Luck!\n\nCheck the video graphics card also. You can test this by placing in another computer and see if you get the same results.\n\n* Well, the fans will work but the power supply will not be able to handle the entire computer. The power supply is weak or damaged, but not totally fried.

1.check your power cord for the computer\n2.try plugging it into a different electric plugin place\n3.make sure the power supply fan is running on back of the CPU tower

if you tower was making a lot of whinning noise before it quit...your power unit/fan puked.  Common item to die when computers aren't cleaned out.\n\nSimple item to replace...just a big box where the power from outlet plugs in the back and inside just a few wires that plug into each item.\n\nCan aways use a meter to see if power is coming through the power box.  Not to mention ensure all connections are good and tight.  Make sure no breaks in any wires or plugs.
