I've got an Ashton Digital Passport 2000+ (www.ashtondigital.com)... at this point, I'd highly recommend to stay away from Ashton... their service reaks of BS.
So I've used ME/XP, and have been having the same troubles for a month or so. My laptop out of nowhere just crashes, get the blue screen. It does it whether it's cold or hot, I've tried reformatting HD, scandisking to remove bad sectors, borrowing friends laptop RAM, troubleshooted software, updated bios, and still does it. Ashton Digital Tech'ies says it may be file corruption from bad connection of HD to motherboard. But the ironic thing is, there are these stickers everywhere in laptop that say if I break them warranty is void. So I can't take it apart to troubleshoot. This is bogus!
Any other suggestions? Oh, and where can I make some noise about how this company's products and support sucks!
