intermittent connection loss

I have had ATT dsl for 8 months now, on the day they came out, turns out the att box on the side of the house had no connection from the pole, so they scheduled a guy to come out and run a new line to the box on the house, he did with a ditch witch, then my landlord saw some of it above ground, so I called att back and they came back out and reburied the line, I wasn't home, so I have no idea how they did it, I got here at the end of the reinstall, I assume they reburied the same line.

Well after that, I noticed when it rained, or seemed to be when it rained, I lost connection, I called them, they sent a tech out, he said everything was fine on their end, but the problem kept happening, every time it rained, I called again, they sent someone out, he couldn't find any problem and said it was fine, but he then wanted to crawl under the house and look at my line from the box to the house.He was under there awhile and said he found a splice in the phone wire and said he thought it was getting wet when it rained, and he thought it was the problem/maybe. Re said he did a temp resplice and recommended I rewire the house with cat5 cable.
Meanwhile I kept losing connection, and was even losing it when it did not rain. then in the last few weeks I have been losing my connction every few mins or so, very intermittent with no rhyme or reason. so I went and rewired the line with new wire, just one wire temp, as to figure it all out, I even got a new phone jack and new N.I.C., and the connection still drops, every few mins. so I called att back last week and told em I was fed up and told em it was on there end, and I had been losing conn. for 8 months and I demanded it be fixed, she ran tests and said it wasn't them. so she put me on hold, I was on the phone with them for over an hour. She talked to a tech. and he told her, since they have came out so many times, he told her to send me a new modem so she did.
the old modem i was using was an att westell, and today I recieved the new modem and it is a motorola.
While doing the self install wizard of the new modem, I lost conn. like normal a few times, until I got to the part where the wizard and net was configing my modem, and then it stayed on, then the next step of the wizard, said detecting modem, and it seemed to get stuck in an infinite loop of "detecting modem" for over 45 mins I let it say that, until I went and opened another browser and went to att chat support, I told her how it was stuck, she had me check the modem config, and at that time, the modem had been on over an hour without losing connection.
I wasp umped as I figured it was all good now, then after being on almost 2 hours it dropped conn.

I am so fed up with this and am now wandering if a virus or program can be doing this unbeknownst to me?
I am lost and need any help, as att seems to say its me and not them.
this has now dropped conn. a few times in a few hours, which seems to be longer periods on than the normal drops.
I am no tech but can build a pc and work on em, to a degree or with the right help and guidance, any help would be so greatly appreciated.

This is a custom built pc, running xp home.

Should I run hijackthis? and have it looked over? as my avast and other security stuff is not finding much.

Thanks so much.

 

You can close this thread now, problem resolved, att tech came out and found a "hard short" in the line between drop box and station.

Thanks...
