[Techtalk] Frozen computer

[Lina Mårtensson]

Dear chix,

my best friend is starting to let me down. It's a 5-year-old Sony Vaio
PCG-F390 laptop, whose memory I recently tried to upgrade. My boyfriend
had some memory that should fit, and all was well for a few days and
then my computer started to freeze. At first I thought it was my new
kernel, but after that I've been running the same kernel I've run for
months, but the computer still kept freezing. To make a long story
short, I've changed the memory back and forth some times now, and
somewhere in the middle I thought I'd broken stuff permanently but in
the end it just seemed as if I hadn't put the memory in correctly.

A few hours ago, I just put back the original memory, thinking I'd just
have a slow but at least reliable computer. But it froze again. Could I
have caused a glitch somewhere while fiddling back and forth with the
memory? Or is it something else that just happened to coincide with the
change of memories? How can I find out what the problem is? I left the
computer running with memtest86+ all night (with my boyfriend's memory),
and it didn't report any errors, but as soon as I booted into Linux my
computer froze again. It has only frozen when I've been using it so far,
though, which I was obviously not while running memtest86+.

Can anyone help me?

Thanks.
