Installed it in my old dell 4400 Sunday, loaded XP, set up users, wireless working, printer etc. shut down for day and it has not booted since. Power on, lights briefly on cd, DVD, keyboard, dell logo appears for a SECOND but not long enough to get a response from f12 or f2. No instructions came with this WDHD no cd, just a box with a hard drive. I tried the dell boot cd with no joy as well. Dell recommended this drive but will not answer questions about it because it is not dell. I have limited comp knowledge and I have hit that limit. Need some instruction or hints dumbed down from most of what I have seen here. Thanks in advance. Terry
