I have been trying to fix this for a week. I had a problem with my mother board and had to replace it. After doing this we where having some problems with the computer where a few minutes after logging on it would go into a black screen for no apparent reason and get stuck there. We tried to use a windows recovery (which may or may not have been of a legit disk) and after doing this when windows loaded the screen would refresh in a "blinds effect" ... by this I mean, if I open my documents, or a program or anything of that sort... the program goes up as if a line ran across the screen from top to bottom. If I minimize something it disappears the same way, from top to bottom. Resizing a window has the same effect. If I maximize it is reversed, it goes from bottom to top.. the window appears as if it where being teleported in. When using internet explorer or firefox to scroll through webpages, they almost "wave" as you scroll down... again this is the line effect just faster. (when scrolling it is as if multiple lines are going up the screen to produce a wave look). So to fix this problem these steps have been taken. 1) Two different video cards and monitors have been tried. Same problem, either way. Windows has been formated an reinstalled, using two different xp disks to make sure it is not a problem with the disk. (this was done in the original computer) The hard drive has been switched for a new one and windows has been freshly installed on that hard drive. Same problem. Now here is where it gets tricky. A (test) hard drive with an existing functioning copy of windows was placed in the problimatic computer and ran fine. The problematic hard drive was placed in another computer and produced the running line problem. For this reason we thought it was a problem with the xp disk (since the originial problematic hard drive started the problem after being exposed to the disk, and the brand new hard drive had the same problem after using the disk, and the test hard drive ran fine and was the only one that used a different disk) So we finally thought we had things good to go, we installed windows onto the original hard drive with a FRESH copy of xp (this was done using a different cpu then the one of the original problem).. the hard drive was then moved into this cpu. It ran fine for a solid 5 hours. After feeling safe and confident that the problem was gone and it was infact a faulty xp disk, I plugged in a 2nd hard drive (which I had backed up a few files on) and a USB card. As soon as the computer booted up... I knew there was a problem. The drivers hadnt even had a chance to install for the new hardware, by the time the windows login screen loaded, i seen the line of doom run across it.... For the love of god, someone please help me. I'm out of ideas. (if anyone is having a hard time understanding what i mean by a line running across the screen... i can post a video) **I also just noticed that typing on some sites is impossible. For example on here, I type and it goes flawlessly. I just tried to type something on yahoo answers and it took nearly 5 minutes for a sentence 10 works long to appear, taking about 10 seconds for each letter to show up. During this time I was unable to click on anything else or scroll, it wasn't even my screen lagging, my entire computer slowed almost to a halt) I'm running a gig of ddr2 ram, it shouldn't have any problem running nothing but a web browser.
