Hi guys and gals, I'm currently having a few issues with my TX1001AU. I've been chatting to HP Support since February regarding my Broadcom wireless, which isn't detecting, but they've been about as helpful as having herpes in that department. I've lost so much faith in the brand due to their lack of clear and unambiguous responses. Anyway, enough whining. My TX1001AU recently displayed a: IRQL_NOT_LESS_OR_EQUAL bluescreen, and hasn't come on since. Essentially, I need to re-install Windows Vista, but would like to recover my data beforehand. I've spoken to thebranded on these forums, and he is sending me a copy of the recovery disks (thanks again bud) due to me being in the UK for 2 years and not being able to find my recovery disks, so should be able to do that. If not, will have to find a copy of Windows Vista Home Premium, which would like help on if anyone is willing. But the main point of this post is to ask about the HDD. If I wanted to upgrade the 120GB SATA HDD, what would the largest size be? The sweet spot, pricewise, seems to be the 320GB drives. However, I'm not 100% sure that the motherboard will recognise that. According to the ever helpful HP Support, I can run a 160GB HDD, but I know that another user on these forums is using a 250GB. Would anyone be able to help me out in this regard? Thanks in advance for your help.
