PCG-K215Z Freezes randomly - help!

[WarwickNP]

I have two PCG-K215Z one on original software, one had a clean reinstall, both run XP SP3. Both randomly freeze without warning requiring a reboot - especially when they have been left with no input for a few minutes. No issues are shown in the error logs and nothing seems amiss in the services or system hardware - no conflicts are shown.  Both are running 1GB of Ram  - I have tried everything including chkdsk, and driver update scans but to no avail and cannot fathom it - has anyone any ideas or suggestions? Has anyone had a similar experience that they've cracked? Please help!

i had the same issues. went to all the "experts" and paid a lot of money for people to scratch their heads. It turned out to be a CPU issue even though the notebook was not even 18 months old and everyone said it could not be the CPU as it was booting and working before freezing. Replaced it and its fine.
