Here's my rather sad experience with my less than a month old K42jr. It crashed two weeks ago and would not re-start. Sent it to the retailer and was told the mobo was busted and needed parts. Asked about the possibility of changing to a new laptop, the retailer said they'll see if it can be repaired first. Recieved the repaired unit yesterday but now the unit shows artifacting green spots. They only disappear when placed in battery mode or when the video card is only working at half the capacity. Will return the unit to the retailer on monday. If the retailer does change the laptop to a new one, there's another problem with the Windows 7 which I bought from the same retailer...

You are having Windows 7 Home Premium OEM.

If you are having an OEM (Original Equipment Manufacturer) license, you would not be able to transfer the license to another computer, particularly with a different motherboard, if you would like to use the same license , you need to purchase a new license for the other computer
