Hello,\n\nI recently purchased a HP a6200n which works relatively well. The only\ncomplaint is that frequently (at least once daily) the system will lock\nup. When this occurs the only way out is to hold the power button down\nand reboot.\n\nWhen the system locks, the screen will actually freeze the contents and\nmake it appear somewhat 'snowy'. This happened on a factory system OUT\nOF THE BOX. So I know this wasn't due to application software I loaded\non top and I doubt very much it was a virus the system picked up.\n\nSince this started I have done a full virus scan and also have reviewed\nthe event logs after each fail and nothing in there is obvious. There's\nan 'unexpected reboot' message there from my forced power down.\n\nI've gone to nVidia to download the latest nForce 430 drivers which has\nnot helped. It seems ahead of what MS is pushing as the version I have\nis dated 12/07 and the auto updates are telling me to pick up a 7/07\nversion.\n\nI've also loaded SP1 and all of the HP/MS updates a person can handle.\nHas anyone experienced this or have any suggestions on what might be the\nnext thing to look at?\n\nThanks!
