It could be because of many things. Too many temp files, Too many temp Internet files, your C: drive may need defragmenting. You could have spy-ware/mal-ware, or a virus, not enough free space for the operating system.

Or the number one cause for a Windows system to slow down, The updates from Microsoft. They seem to think that a computer should start out fast and then start slowing down, that way when the new computers come out you want to go out and get a faster PC and they get to sell another operating system, again.

What's a modem initialization string?
Before your modem software dials a phone number, it initializes (inits) the modem by sending it a series (string) of commands, typically Hayes commands. These commands configure the modem's options for things like error correction, data compression, flow control, and many other parameters. The modem manual should list the Hayes commands the modem recognizes, and what effect each command has.
The important thing about modem init strings is that having the right one often makes the difference between connecting and not. Init strings are fairly specific to each modem. The string that made your friend's modem fly may not work at all for your modem.
Not all programs use simple init strings. Some use settings files, such as Windows 95 .inf files, Mac CCL modem scripts, etc.
Tip: You may also want to try one of these generic init strings:

* AT&F
* AT&F1
* AT&F&C1&D2
* AT&F1&C1&D2

modem strings:

Tip 2: For K56flex modems, try one of these generic init strings:

* AT&F+MS=56
* AT&F+MS=56S202=32
* AT&F1+MS=56
* AT&F1+MS=56S202=32

Answer 7

Your computer slows down due to too many things to mention, but go to the explorer properties and delete all files. cookies, & history. Then go to my computer and open this up, then go to properties and do a disk clean, which will free up a lot of space for you. Make sure you have sufficient memory to accomodate your needs on the compter. If you have your unit set to hybernate, uncheck that box as to not delete the files for that.
