Hi,

I am having some computer problems that are starting to drive me insane.

At home, I have a wireless internet connection. We have a linksys router and I am one of the computers on the network. My dad's pc (the main pc), my sister's laptop, and my Macbook can all connect to the internet without any problems.

I also have a PC that I built over the summer with my uncle. The PC connects to the internet but after 10 or 20 minutes it looses connection. I will then either have to wait a long time or restart the PC. Sometimes it never comes back unless I reset. Also, this problem did not happen all the time. Only once and a while.

Before I moved into my college dorm, I reformatted my PC and started fresh. I installed my linksys drivers and graphic card drivers. I then headed off to college.

At college, our internet is not wireless. It is wired. I could not connect at all.

I took my PC to the computer help people at my college. It took them 4 days to get me online. They said that I was behind on Microsoft updates and that was the reason I could not get online.

They also installed Norton Antivirus and NViDIA Firewall for me. Before I left, they suggested that I add more fans and a larger power supply to my PC. I have two powerful NVIDIA graphic cards and they said they need more power and get too hot.

All way good. I went back to my dorm and connected to the internet. But now I am having the same problem but with a wired internet connection. I can only connect for so long before the connect dies and I can do nothing to fix it. I can only restart my PC and wait till it kicks in again.

I also tried turning off the Norton Antivirus and NVIDIA Firewall. I need the Norton in order to connect to my college internet though. It is required.

Still no luck. I really have no idea how to fix this problem. My Macbook connects fine to the internet and my roomate has a PC and he can connect.

Any suggestions or advice would be greatly appericated! :)

(Also, a friend of mine said it might be the power supply. Do you think that is the case? If so, if I go into BestBuy tomorrow, will any power supply of a higher voltage work? I am new to this stuff)

Before recommend a P/S, we need to know details of the system configuration you're currently running. Truthfully, I'd remove one of the video boards and see if that helps. That would give you an idea if it's a power issue.

One thing you havent stated is your connection type. Is it dialup, ADSL, ISDN etc?
As you say wired, I'll assume you are using the college LAN. You havent said if youre using static or DHCP addressing.
When your connection is working open a command prompt and type
ipconfig /all
make a note of your IP address, gateway and DNS servers. When you lose
connectivity run
ipconfig /all again and make a note of the changes. This should help to eliminate the problem, depending on the results.
When connectivity is lost can you ping the gateway? or your ethernet adapter?
