Biggest Computer Problem

What's been your biggest computer-related problem that's been Hell to fix?

This summer, I bought a Dell. That right away should tell you how the story ends, but I got a Dell cause it had way more RAM than anything else in the store, and I needed something that was about 700 bucks to also get the 360 deal. So I bought it, and within weeks it had problems (Crashing, blue screens, turned on in the middle of the night). Finally, three months after getting it, the screen cracked. Probably my fault, as I brought it EVERYWHERE with me at college.

Nonetheless, I sent it in to Dell to be fixed, because it was obviously still under warranty. Two weeks later, I got it back. It worked for a week, then flat out turned off and refused to turn back on. No lights came on the computer, and if I COULD get it to turn on it turned off as soon as I touched it. I called Dell, they sent me ANOTHER box, and I sent it back for them to look at and fix.

They gave it back to me two weeks later. It wasn't fixed. They had a message saying "Thank you, we had our best people look at it, we fixed your fan" but as I called them, they admitted that no one looked at it and it was just sent back to my house without being fixed at all. That was a giant insult, so I was obviously getting kinda pissed. They sent someone to my HOUSE to fix it. The person they sent missed when they were supposed to be here, twice. Finally, several days later she fixed my computer by taking out the old motherboard and putting in a new one. Apparently something in it snapped off and broke, I'm not a big hardware person.

So I had a working computer again, BUT it broke two weeks later. Again. SAME PROBLEM. So I called them, again, and they sent someone out, AGAIN. He came when he was supposed to, at least, and fixed it. I didn't move the computer from where it was, but just sat there and played Civ4 for a few hours. Finally, I was gonna go back to my room when I picked it up and it broke again.

By this time, Dell basically said "fuck it" and just sent me a new computer. I guess they learned that it was costing them more money to send out people and cheap motherboards to fix it than it would be to just give me a new fucking computer. The new computer has problems too, it has weird sound problems and it crashes every now and then when the video card crashes. Nonetheless, this is the biggest problem I've ever had a computer give me. And I'm REALLY bad with computers.

SO, has anyone had an annoying problem with their computers that just couldn't go away?
