My System not booting even though power supply is well.?
Hi, I've recently purchased a second hand computer. 512 MB RAM and 80 GB Hard disk. Windows 7 Operating System. When I started my PC the CPU starts working but the monitor does not activate. I've checked whether the peripheral is connected well. Every thing is done well. But the Screen does not appear at all. Even the LEDs of Num lock, Caps lock, and Scroll Lock does not glow while starting my PC. Can any one help me Please?
