I've tried most of those, but then my pc started hanging on the startup screen of Limewire, then I started having some other crashing issues etc. I ended up reinstalling windows fresh and reformatting my hard drive due to Dell's MAGNIFICENT support!
ughh... waste of time. Then they tried to tell me that my motherboard was fried. I didnt believe it. So I tried something different and It ended up being what I suspected all along.. the power supply. So now that I am back up and running and have a new slate to start on, I'll try reinstalling limewire, if I can find it on my backup drive, and try again at connecting. But I have been having problems with my other 2 pcs connecting also, so I doubt that it was a technical problem with my computer but rather something is blocking it. I was fine connecting until about 6 months or so ago. Only thing I can think of that has changed is that I now have a wireless router, but I also tried connecting direct to the router and that didnt work either. So I don't know.
I'll keep searching the boards to find something that may jump out a me. Thanks
