I have recently bought hp pavilion dv-1275mx for myself and I have reformatted it and then problem that I am facing now is that I am getting a error message saying that the "Base system device" driver is missing. I donít think that I have missed anything during the reformatting but I am still having this problem. I was not having this problem before formatting. I donít have idea about this so is there anyone who can help me out to get rid of this. Any help regarding the same will be appreciated.
