After removing the annoying spams, you can then look for the culprit that's causing the GoDaddy email server to crash. There might be some hardware problems on your system. Have a hard disk and memory scan performed by a reliable computer technician or PC optimizer. If your ISP has provided a spam blocker, you can then use the software program to rid yourself of any remaining spam. You should also use an updated antivirus and anti-spyware program that you have bought especially for this purpose.
