anyone have any probs with their puter freezing whilst using videoediting programs like tmpgenc, virtiualdub etc? its only happening when i use these processoe intensive apps. i've changed ram, graphics card and hard drive and done a fresh reinstall of xp. im also getting this with only xp and virtualdub and tmpgenc installed on the puter so it cant be a software conflict. it used to work ok so im totally stumped other than to think it may be a processor or mobo fault.btw ive got an amd 2600xp+ processor. any advice would be great.
