Query: Problem- Is it HP or Vista

I purchased this computer several months ago. While I have enjoyed the computer so far I have never had a computer lock up and crash so often. I am not at all impressed with Vista and would not get Vista again if I had a choice. The hard drive seems to run way more then any other computer I have had. Sometimes when I run defrag it defrags in about an hour then the next time its a day later it's still trying to defrag and you have to hard boot the system. While I have had several HP computers not sure I would buy this one with Vista again until the bugs are out. Oh and by the way trying to get HP Tech support is next to impossible and when you do they don't seem to have a clue!
