why is my computer beeping like a police car?

When a computer is first turned on, or rebooted, its bios performs a power-on self test (post) to test the system's hardware, checking to make sure that all of the system's hardware components are working properly. Under normal circumstances, the post will display an error message; however, if the bios detects an error before it can access the video card, or if there is a problem with the video card, it will produce a series of beeps, and the pattern of the beeps indicates what kind of problem the bios has detected.

If this is your hard drive, you should TURN OFF the power.   That sound could be from the hard drive, and you have little time left.  Save your data and make backups, then get a new drive.   \n\nGood luck

Its quite possible that you have a Macro running in the background that is interferring with your foreground activities.\nShut any Macro programs down and try again.\nIt would also be a good idea to run a virus scan using the latest updates as a Macro Virus could have also infested your pc

Its now called Windows Defender (Beta 2). if you have that, it does a very good job of hiding itself, such that you don't know its running until it senses an attack

Sound like your computer is running in the (safety mode) Try running your antivirus software to check for viruses as something is putting it in the safty mode.

it is either a bad ground... assuming you have no surge protector, just have the computer plugged directly into the outlet, or it is gremlins in the tower humming along.

it is possibly your wireless phone that intercepts certain sequences of code interpreting it as information it should have, not your computer, try moving you computer, router or phone

Do you have the manual?  Usually beeps like that are in a specific sequence and it is trying to tell you something is wrong or about to go wrong with it.  Check the manual or look for a help line and tell them about the beeps.  A friend of mine had this problem.  She had 2 short beeps and then a long one...over and over every few minutes. Turned out she had a bad stick of memory in there.  She replaced it and all was well!

it could be the fan is dirty or the heatsink is dirty, try blowing those out and turning on the temperature again.  It could also be beeping because of a different problem.  RAM issues make beeping sounds.  With the temperature off, it could easily ruin your cpu.  I would fix it asap.  If it is a laptop, some laptops have issues with this problem.  If it is a laptop I would call the manufacturer and get it fixed by them if it is under warranty, otherwise, it could be expensive.

Oooo, bad noises. If it was a problem with the circuit board I could give a suggestion, but those noises mean that the "heads" that read the data off the platters were hitting something inside the dirve, and from your description of the sounds, I'd say what they were hitting was the platters, where data is stored in a hdd :( Bad news, that. Some of your data would probably still be recoverable, but not at home, not without a clean room. There are companies who specialize in this, but it's expensive, and they usually charge by the megabyte. Google "data recovery specialists" if you want to find one near you.

Why did you take the battery somewhere to be charged if the laptop is not on but you have it plugged in you are charging the battery.  Check the metal connectors on the battery for corrosion, dirt, etc....  When you hit the power button does it make any noise(beep, humming?)?

What your computer starts up, it does a POST (Power-On Self-Test). It is normal for a computer to have 1 beep. Multiple tells you that something is wrong with the system.  You didn't specify how many beeps there was or length thereof. \n\nA steady short beeps says Power Supply may be bad. \nLong continuous beep tone says Power Supply is bad or not plugged into board correctly.\nSteady, long beeps says Power Supply is Bad\nGriding noises that is outside normal cpu processing may suggest a CPU fan problem.\n\nIf it is the power supply issue, you need to replace it. This can be tricky because small computer (2 cdrom bays) requires Micro ATX Power Supply. Midtower (Has 3 CD bays in front) can fit ATX power supply.\n\nIf Griding noises from cpu fan, just goto local computer store and tell them what processor you have. Rep can probably help you. And they are a easy to install.\n\n\nYour aim problem may suggest a virus or hacker.  I recommend getting BitDefender Anti-Virus. And download their CD recovery iso. It uses BitDefender for Linux and boots.

It sounds more like Spyware. They are usually installed in your PC when you enter a malicious web site or install something "for free".\n\nTry downloading and using SpyBot Search & Destroy.\n\nGood luck!

The 4 beeps mean that the memory modules can't be accessed. \n\nEither the memory sticks have come unplugged (from bumping the laptop against something) or they have gone bad. \n\nIn either case, the laptop case has to be opened to examine the memory. Computer shop is your best bet.
