I am hoping there is a computer specialist or IT person that can help me with a problem that has started with my computer in the last couple of weeks.<br /><br />I purchased a new computer a few months ago (HP Pentium IV 2.8 Gig /512MB Ram) running Windows XP. I wanted to have a home LAN to allow the kids to use the old computer (Pentium III) so I purchased a 4 channel Lynksys hub/router connected to my SpeedStream DSL modem.<br /><br />I set the system up and all worked well for the first few weeks and then suddenly my e-mail connect on the new computer failed after about half an hour after re-booting the computer. I can still surf the web and can actually send and receive e-mail using the old computer without problems. If I reboot the new computer the e-mail connection works again for 1/2 hour then I get the error messages "the connection to the server has failed".<br /><br />I have tried to eliminate the old computer by disconnection the LAN and just have the new computer talk to the router/modem.<br /><br />I have run Norton Antivires and no problems found.<br /><br />I was originally using the full Microsoft Outlook and tried Outlook Express but the problem still exists.<br /><br />This re-booting every 1/2 hour is driving me crazy, any body have an idea what is wrong?<br /><br />Thanks in advance for your time!
