Hello, guys! Long time not writing anything here. Last time you help me a lot and I wanna thank you again. So here is the new problem. One friend has HP probook 450 g1 laptop. I reinstall his windows and its fresh Windows 7 64 bit. The problem is when he start the laptop a black screen appear with CHKD test of hard disk and the files on the hard disk. All the time test said HDD is ok but never stop. Sometime the laptop is loading slowly but he works without any problem. I saw the PAGE FILE is moving to another place in C drive which I think is an another issue that I need to tell you. Thats why I think its a problem with Hard disk or with HDD files system. Probably there is no problem with Windows because its fresh installed, all partition are new created and formated. If you have any suggestions or idea what may be the problem I will be happy if you comment and help me. Thank you!
