I'm currently investigating the boot-up problem known as a [ITHR] problem for my work.
ITHR refers to the Internal Thermal Probes on the CPU. These probes check the temperature of the CPU. When something's wrong with the probes (or when the system detects something wrong with the probes due to the possible problems below) the system stops booting and it just gives following errorscreen
"Alert! Previous attempts at booting this system have failed at checkpoint [Ithr].
For help in resolving this problem please note this checkpoint and contact Dell Technical Support"
What can cause this error?
Well, this is the problem since quite a variety of problems can trigger the error.
1: the bios can be malfunctioning (a bios reset or flash can give a solution)
2: the cpu can be malfunctioning (this requires a new cpu)
3: the cpu socket can be failing (this requires a new mb)
4: the problem can be with bad usb sockets
5: even a bad uplink to a usb hub can cause this error to appear.
I've already got quite some info on this error and possible solutions, but it would be great to learn more. Can anyone give some more info concerning this problem? Causes or solutions ... ? Anything is welcome. Thx in advance ...
