Specs: Windows XP, T2050
One of my two hp dv5000 laptops suddenly stopped working last Friday. It endless reboots. It goes to boot options first and starts Windows logo page, then restarts. Here's what I did:
- tried safe mode and last good modes; saw boot after mup.sys. Google
- I pushed F10 and hard driver diagnostics says everything is okay.
- I then tried to do recovery by normal recovery from recovery partition, failed.
- Then, I tried recover by reformat hard driver. Still failed.
- swapped RAM of two laptop; good laptop is still good, and bad laptop is still bad;
- swapped CD, same result
- swapped hard drivers. The problem followed the "bad" hard driver. The "bad" laptop became working with other laptop's hard driver. So, I guessed the problem is "bad" hard driver and everything else is good.
- I bought a new hard driver. After installed all recovery disks, the problem still happens.

Can anybody help?
