I bought a Compaq Presario about 4 years ago. Within the first 6 months of having it, my foot got tangled in the cords and I accidentally pulled it off the desk and it hit the floor. Since then it has had the same problem, and although I've sent it to Compaq a few times (during the first year manufacturer warranty) and sent it to Circuit City (with the warranty I purchased with the computer), nobody has ever fixed it. It's been in my closet for a couple of years, and when I was packing up my stuff to move out, I came accross it again and I really want to figure this out. So here is the problem: IF it successfully boots up, things will work fine for a while, but the computer will eventually just turn off by itself. Most of the time it won't boot up at all. Sometimes, nothing will even show on the monitor. Sometimes, the compaq logo will come up, but it never goes past that. And when the compaq logo comes up, there is a bunch of matrix-looking shit scrolling behind it... ? Since it starts up sometimes and works perfectly for a few hours (normally), I assume that its not THAT messed up...maybe there is only one or two things that I'd need to replace. Any ideas, OT?
