After having read these post: Mathematica 10.0.x freezes in Initializing kernels, Mathematica sporadically crashes on open, Front end freezes on start-up, I have borrowed the title for this question from the former, for reasons that will be soon clear.
I think that this question isn't a duplicate one because (1) the problem is a reboot, not a freeze (2) all what advised there is fruitless, hence the cause is perhaps different.
On a pc (Windows Xp 5.1.2600) there are installed Mathematica 7.0 and 8.0.
Now 9.0 has been added also, because I need
Cell, and that's my sorry tale:
... Mathematica\9.0\Mathematica.exemakes the system reboots just a second after the "
initializing kernels ..." message
I have inspected
$UserBaseDirectory\KernelBoth contain no other file than
init.mand those files are void. Same holds for
I have launched
... \9.0\MathKernel.exeand performed some simple calculations (
I have tried a clean start using CTRL + SHIFT. It doesn't help.
- I have tried a clean start using
Mathematica - clean. It doesn't help.
- As above many times ...
- Now the splash screen is shown at start of both when 7.0 and 8.0 and the list of recently open files is void (Has the previous option been resetted to its default value ?)
In kernel 9.0
PacletSiteUpdate /@ PacletSites PacletUpdate["CloudObject"]
produces an error:
PacletInstall::notavail: No paclet named CloudObject is available for download from any currently enabled paclet sites.
I have disinstalled all my printers.
- I have turned off
Automatically check for data updatesand
Automatically check for documentation updatesin the Internet Connectivity tab of the 8.0's Preferences menu.
- I have removed
C:\Documents and Settings\user\Applications Data\Mathematica\Paclets\Configuration
- Mathematica 9.0 started one single time and I have been browsing Documentation Center for few minutes.
- Now we go again with reboots.
How can I climb out from the cliff ?
