But it is lacking valuable information. I am not a guru (only second year at using debian), but i am surprised that you feel the urge to reinstall each time. That removes the traces of the previous problem, which can quite likely be found in the system logfiles.
So i suggest, you explain a little, why you want to reinstall instead of just rebooting and logging in, when you would be able to inspect the system a little further. As i began with my new computer, i had similar problems. It was somewhat better after i installed from a DVD with nonfree firmware included. Only after several months, i discoverd a bad setting in computer setup (BIOS) that was configured by the vendor for the purpose of making Windows users happy, was causing MY problems. What may be your problem could be anything from hard- to software, but i suggest you have a look at /var/log/syslog and at dmesg while your computer is running fine. And let us know, what you found.
