During your boot screen press the F8 key to boot into safe mode. If that gets you to the desktop run virus/spyware scans. Reply with any results.

SOURCE: IBM Lenovo doesnt start
Sounds like your graphics card and display are not properly communicating. If the card doesn't sent out a signal to the display, you will see nothing on the screen. Did you check the graphics card on another machine using the same display? If so, something different may be wrong. I am assuming your display is powered on and plugged in properly. If there is more than one video connector on the machine, you may have it plugged into the inactive video connector. If all of this checks out I suspect you have some hardware problem with the system unit.

SOURCE: I have HCL Ezeebee desktop computer when we boot the system monitor, keyboard, mouse blink for a while and monitor (HCL) show 'no signal' message, and keyboard num lock led not display mouse i
No signal at the monitor indicates (if you know the monitor is working ok) a failure of the graphics chip or graphics card, The lack of indicator light on the num lock LED and the lack of power to the mouse would indicate that there is a major issue with the motherboard.
you can try using another monitor to confirm the problem lies with the graphics, and in the case of the keyboard and mouse, swap them for a usb version, if they work, the Ps2 ports are probably damaged.
I'd be thinking of replacing the motherboard
