My computer starts up and when XP is ready for me to log in, it starts buzzing. It sounds like it is coming from the processor. It acts like something is using up all its resources. Any hints? kennerphil..... Are you able to log in ?
Are you certain the "buzzing" is comming from the CPU ....or could it be from the fan or possibly the hard drive ?

dl65  I was able to login, but not anymore. I click on the user name I want, but it does nothing.

the buzzing is more like a continuous beep. I don't think it is coming from the fan, but maybe the hard drive
kernner:

The audible tone you hear may be the motherboard's BIOS beep codes.  Beep codes are a way the motherboard communicates what is wrong (it's something like Morse code, but not as sophisticated).  

If it is a continuous series of beeps that does NOT end, then try this:

* If your computer has an Award BIOS or a Phoenix FirstBIOS, the continuous audible tone indicates a memory failure.  To fix the problem, remove all memory (RAM) sticks except the one in the first bank (the one labeled bank one on the motherboard).  If the beep tone goes away, then one of the RAM sticks you removed is bad or was not seated firmly.  Add one RAM stick at a time till you get the beep tone again.  That stick may be bad.

* If your computer is an IBM, the continuous beep tone means the power supply or the motherboard is bad.  Have a computer repair shop replace the power supply for you.  If that doesn't WORK, have the shop replace the motherboard.

If the audible tone stops after SEVERAL beeps, then your system may have a Phoenix BIOS 6.x or later.  In this case, count the number of beeps and pauses between the beeps.  Write them down and let us know the number of beeps between each pause.  We will let you know what the cause is.

Take the case door off and inspect all hardware.

Thanks for hte responses.

The beep is one long contiuous beep, not a series or anything like that. I will CHECK to be sure nothing is loose inside, then the memory sticks.

Thanks againNothing appears to be loose. Only one memoey stick.

Sounds like either the motherboard or power supply.

Not that I know much about this, but it seems wierd that it starts and gets to the point to where I am ready to ogin into Windows XP HE, then it starts beepng. The curser moves but nothing happens when I click the mouse.

I was able to get in before, but it seems to be worse now.

GUESS I'll have to bring it in.Can you start in safe mode?
