The wifes aspire one has started freezing, sometimes upon boot, sometimes after a couple hours use. becomes completely unresponsive. Have done many different types of virus and malware checks with nothing outstanding appearing. used ubcd to check the hdd and it shows it to be healthy, though it is the hdd i suspect. without a 2nd hdd and the means to reinstall windows, what else can i look at? ideally before the wife attempts to fix her self by launching it out of a window !!
