Hi Silas, My apologies for delayed response.  You can check the SATA Operations in system BIOS. Change the SATA Operations from AHCI to ATA or vice versa as shown in image below: [IMAGE] Also please make sure to remove all the external peripherals connected to your computer and remove the SD card from the slot if connected.  See if it makes any difference. 
Hey all, I have recently tried installing Windows 7 on my brother's laptop to try to upgrade it from Vista. The install went well, but when it tries restarting for the first time, the screen stays blank without booting. I've tried formatting the drive and trying again and still nothing. Any idea what it could be? Silas
