Windows 7 Ultimate stops at Logo screen
Posted on 2012-03-24
My compuyter froze (Dell Precision M6400) when I inserted it into my docking. It has been working fine for the last 4 months. I had to do a reboot by holding the power button until it shut down
After this the computer will not boot. It stops at the Windows Logo screen. It does not freeze, the Logo is moving (pulsing) but it does not get further.
I have tried safemode with and without networking but it always stops at the CLASSPNP.SYS file and stays there. I have tried Last good Known Configuration but it still stops at the Logo screen. I have also tried "startup repair" but it keeps running forever with no luck.
I also tried booting from the Windows DVD and selecting repair. It then list up a partition D:\ with Windows 7 OS. But another box pops up which says searching for operating systems installed or something. This box never disappears so I just have to hard reboot the machine again. Also my OS is installed on C:\ so I don't know why it says D:\
I have removed the HDD (SSD) and tried booting with the original SATA drive the computer originally was delievered with (I have changed to SSD) to make sure there was no hardware problem (except for maybe a problem with HDD). It then boots up fine.
I have also tried connecting the SSD with the OS to another machine with a USB dock and it also come up fine. The HDD seems to be working fine so I guess there are some corrupted files that is the problem. I did a chkdisk from this other machine when I had the HDD connect to the USB dock and it found some problems and fixed it but it still hangs on the Logo screen when booting.
Anyone has an idea how I can solve this problem?
