Toshiba M-45 laptop with xp home(sp3), mobile intel pentium m730, mobile intel 915GM video adaptor.
When computer has been off, it boots up just fine, but after a period of use (sometimes as little as 10 minutes) if you reboot, the screen either goes completely black and nothing happens or it starts the reboot, displays the toshiba splash screen but using only 2/3 of the screen space and then freezes. In either case have to manually power off, wait a bit then power on, often repeating several times before it finally boots up again.
Actions taken so far:
In april I thought this was maybe a virus so opened a ticket on the virus side of the house and we spent several days trying all the excellent ideas given in the hopes that we would find something but nothing located. Since then I have reformated the hard drive and reinstalled xp home and ubantu along with a couple of utilities (winpatrol, everesthome220) Still have the same issues with reboot, although sometimes it also freezes when it goes into standby mode and won't come back up with out power off.
I am wondering if this could be a heat issue? It seems to heat up quickly,even when not plugged in and charging. I have been watching the temp with everest home and the cpu temp started at 35c and is now at 42c after about 15 minutes of up time and no activity (I am posting this from my desktop while watching the laptop). The hard drive has been steady at 85F. The fan runs and I can feel warm/hot air thru the vent. I have opened the bottom near the heat sink and sprayed compressed air to make sure the vents are clear.
Appreciate any thoughts or suggestions. Thanks
