Dell laptop freezing

Hi All
Hopefully someone has some knowledge of this:
Dell Inspiron 1500 laptop
the machine started to suddenly freeze as different points.
Almost everything pointed to overheating but all diagnostics checks
passed
With an extended warrenty - dell was called and 72 hours later (on a
within 24 hour on site warrenty) a tech came out - ran the same
diagnostics - everything passed - and left saying that it was a
software problem.
The machine is protected by a network firewall -- was running zone
alarm - had spybot search and destroy, adaware se and pest patrol
used weekly as well as a virus blocker.
After the tech left - diagnostics programs were run again - all clean
- the start-up and services under msconfig were carefully scrutinized
and any unneccesary items shut off - to no effect on the problem.
The machine seemed to run okay in safe mode and all manipulation was
done in safemode.
But the machine still would freeze at different points. Sometimes it
would freeze while loading drivers. Sometimes it would freeze at the
password screen. Sometimes in the middle of entering a password and
sometimes after everything loaded, password accepted and then trying
to run a program.
Also - after shutting down (by holding in the on/off button -- NOTHING
would work after a freeze) sometimes (about 2 out of 5 times) the
machine wouldn't even get to the BIOS but would freeze on turn-on
with a blinking cursor in the upper left. IF we unplugged from the
AC adapter, it would then boot from the battery. (there are two
machines - bought 1 month apart - battery and ac adapter were tried
from the good machine with no difference.
Finally - we decided it must be a virus or something and decided to
reload windows. A full format of the C drive was done (partition 2 -
there is a very small partition 1 that probably holds some proprietary
Dell software) - the rescue disk was used and everything seemed to go
smoothly. But upon completion - we still had the exact same
problems.
Ran the Dell resourses disk and it said that drivers were loaded and
functioning
Again we ran the diagnostics programs - although now it was starting
to freeze in safe mode also. At one point - in full windows mode,
not safe mode - I actually was able to get to the device manager and
found quite a few devices with yellow question marks:
Base system Device
Ethernet Controller
Multimedia audio controller
network controller
PCI modem
Video Controller
Video Controller VGA
Was going to try and reload those drivers but as soon as I
right-clicked - the machine froze again.
I'm probably leaving a few steps out and I'd say we tried everything
but if we did - then we would probably know what was wrong.
It still sure seems like this is a hardware problem
I'm not sure what to try next.
Anyone have any experience or thoughts with this?
Thanx!!
