I have had the DELL INSPIRON 9300 for 10 months now. The first 3 months were error free then I have had problems with the screen freezing, meaning no keyboard combinations or mouse movements work. I have seeked dell technical support running the diagnostic test and rebooting to restart the laptop to its factory settings. Even though the long process worked, it had now started up again - just after 2 weeks of being restored. Can anyone help me please, or have had the same problems?

I have to disconnect it from the battery (which is dangerous) and is very disruptive for losting work and so forth. I have up to date internet security and virus protection software, so that is not the case.

Thanks in advance.
