I have a problem with a laptop that I have not seen before. The original problem was the original heat sink assembly was not working so I ordered a new assembly straight from HP (It's an HP Pavilion dv9728ca running vista home premium). I installed it and the laptop booted into windows. The problem is, when in windows, is that anything I tried clicking on, it would say "windows has stopped responding" and could not do anything. I tested the hard drive with seatools and it passed both the short and long test. I then ran a chkdsk /r from a different computer (I hooked it up as a secondary drive and ran the chkdsk /r from a command prompt.) It said it found/fixed errors so i put the drive back into the laptop and since then, I am not able to boot into windows. It posts and then goes to a black screen with a bunch of weird characters/numbers in the upper left hand corner and I never seen anything like it before. Since it still was not booting into windows properly, I took the drive out of the laptop and hooked it up as a secondary drive again and ran a program called partition table doctor. (Used several times in the past and never had a problem with it). It said that there was a partition error so I let the program fix it. Everything seemed good but still could not boot into windows. I booted to a vista cd and tried running startup repair but it says it cannot find anything wrong. Tried a system restore but there are no restore points available. I also ran memtest and that passed. I cannot boot into safe mode because the weird letter error comes up before I can attempt to boot into safe mode. I'm out of ideas and would greatly appreciate any other ideas to try. Thanks in advance for the help
