Hello, I have a Presario CQ56.
We have had this issue before. Several years ago my laptop began having startup issues, where it would get stuck on a black screen with the mouse cursor right after the Windows page. Since it's been over three years, I don't recall exactly what everything we did to fix the problem was, but I know that the problem persisted even after recovering to factory settings with disks. Eventually we gave up and replaced the hard drive and it's worked fine until recently.
Right now, the black screen w/ cursor happens for a maximum of ten seconds before and after the windows screen, but once it's up it runs fine. I know the issue is likely to get worse. If it IS the hard drive, is there a way to test this? Are there any diagnostics we can run to determine a possible cause? Should we nip it in the bud and replace the hard drive right away?
The hard drive that replaced the original was a completely different brand if I recall. I'm curious to know if this problem could be caused over time by the fact the laptop runs hot. It always has, the fans are very loud, and if I remember correctly that is a problem with every Presario CQ56. It wasn't exactly an expensive piece of equipment.
If anyone knows of possible solutions it would be much appreciated.
