12. I installed the TCP Optimizer, and now Windows crashes, my programs don't work and my PC seems to be melting ?

The SG TCP Optimizer simply changes a few networking related buffers in the Windows Registry. It's almost impossible for the program to cause crashes or have any such negative effect on your OS, look somewhere else.

The worst that can possibly happen by using the TCP Optimizer (although highly unlikely) is for you to lose network connectivity, in which case you can restore your Registry to a previous state.

You can use the TCP Optimizer's "File>Restore Windows Defaults" or "Restore backed up settings" menu, or you can reset TCP/IP.

Try checking your colling fans, inside and out for dust and dirt. especially the one on the CPU! TCP Optimizer did not cause overheating.

This is not entirely accurate. When I set the "Optimal Settings" in TCP Optimizer and then rebooted my computer, I got a BSOD immediately when my wireless adapter tried to connect to my network. When I rebooted again, no BSOD, but winlogon.exe crashed with a fatal error. I restored my registry settings from right before I changed them with TCP Optimizer and rebooted and everything was stable again. So the registry settings TCP Optimizer changes can lead to crashes.

I stumbled upon this site when I was trying to troubleshoot my own BSODs that I never had on a particular computer before I ran "TCP Optimizer for XP" from comcast's site. I got 3 BSODs within two days after running it, but, after I reverted to old TCP settings two weeks ago, I had no BSODs since then. My interpretation is that it's the driver for the network card - changing TCP parameters in Windows registry could have such indirect effect. Of course, it's the driver to blame, however, normally, a user, naturally, should not care too much whose fault it is exactly.
