Every 2 or 3 minutes, my Dell computer is "locking up", during any normal function for about 45 seconds, including internet browsing. I used to think this was simply a cable modem issue, but it isn't. For example, I will try to load a webpage and it just stalls for 45 seconds...not even attempting to open the page...and then the page fully opens 45 seconds later, in like 2 seconds. If I try to open ANY Window based program at the same time, it also won't load for 45 seconds. Then, EVERYTHING suddenly loads at the same time. It's like there's something holding everything up, at the exact same time. I tried to open Windows Media Player during one of these freezes, and it also froze. Then, 45 seconds later, at the EXACT moment the web browser kicked in, so did the Media Player. Like I said, this problem happens every 2 or 3 minutes...without fail. It's like clockwork.

I have called AT&T DSL CABLE, and we have both figured out that it's not the cable or modem. It has something to do with my system. They lead me through to deleting temp. internet files and clearing the history, etc...but it did nothing to fix things.

HELP!!!!!!!!!!
