Hello, all. I have an old Compaq Presario C700 laptop that I've been playing around with recently, and I keep getting a white screen, followed by an instant shutdown. I've installed both Windows 10 and XP (individual, not dual-boot) and the same thing happens at random times. It's even happened with no operating system on the hard drive at all. Could this be a failing graphics card? It couldn't possibly be a driver issue. Thanks for your help!
