Laptop powering off

Wonder if anyone has any ideas on how to even troubleshoot (laptops aren't an area I know much about)
Tonight my laptop (an HP Pavilion dv7-6c60us, ~2 years old) decided to enter the terrible twos. It won't stay powered on for more than a few minutes; sometimes it's able to actually boot into windows (where after a few minutes it powers off, similar to if you ripped the power cord out of a desktop), other times it has an unrecoverable error in bootup or shuts off during booting. It does seem that the longer it sits off, the longer it can stay on.
When I bought it, I swapped in a hybrid hard drive (one of the Seagate Momentus XT drives, I copied both the HP fake recovery drive as well as the C: drive when I installed it 2 years ago); I was able to pull that hard drive out and connect it to my desktop (had a couple extra SATA ports), and it doesn't seem to have any issues (i.e. backing up the most recent things has been fine). Conversely, the laptop still crashes when I put the old (original HP) drive back in.
Right before it crashed the first time, a USB-drive plugged in mouse stopped working and the laptop popped up an error message about a device either failing or not being recognized; the last time I tried to turn it on, before it shut off I was able to pull up the device manager and there was an "unspecified -> unknown device" with errors (checking properties, it looked to be the USB controller).
Is it possible that a failing USB port / controller could cause all of those? Or a short in the USB system somewhere? Any ideas how to troubleshoot that / other ideas?
thanks!
