Hey guys !
I've been having some problems with my HP nx7400 that is really spooking me out. The problems started a month ago, but because of school I haven't been able to act on it and had to learn to live with it (if this can be called living).
So... A previously perfectly-working system started to freeze up in the most awkward of moments:
- First I blamed the power cable, but I ruled that out when I switched cable
- I then blamed heating of the CPU but it freezes even at 49 C
- It never freezes while it's on battery power
- It freezes when I plug it in (about 50 % of the times I manage to plug it in without having it freeze up)
- If I manage to make it work w/ it plugged in, I'm deadly afraid to move it because "physical activity" seems to set it off. Again, most duplications of results (90% of the times it's plugged in) happen if I move the lid (which makes me suspect faulty wiring !?)
- Other 10%, it will just randomly freeze up after a couple of hours of media (music - movies -- didn't experience any freezes when I just reading a .pdf / writing a document)
- I have ran memtest / an hdd diagnostic tool, which both came up empty.
- I have also tried to boot off a linux CD but it also froze in the same conditions.
Googling didn't help.
If anyone is familiar with anything like this ...
Thanks loads !
Cheers !
