CPU fan MUST spin everytime the computers starts otherwise your CPU would grilled from medium to well done..check if your cables are intact and not loose(VGA Cable),or the monitor loses power.

There are 3 ways that a display could go blank while the CPU is still running.(self experience)
>>> 1st Way: Screen saver:
Change Screen Saver Settings

1. Right click on the desktop, then click Personalize.
2. Click Screen Saver on the bottom of the Personalization window.
3. change it to “NONE” or increase the waiting time(your call.)

>>>2nd Way: Power Settings
Go to
Control panel > Power options >Choose when to turn off the display (look for this in the side bar)
1. Set “TURN OFF THE DISPLAY ” to NEVER
2. Set “PUT THE COMPUTER TO SLEEP ” to NEVER.
3. And then continue to “Change advanced power setings”
4. go to "SLEEP"
4.1. set "SLEEP AFTER" to NEVER.
4.2. set “ALLOW HYBRID SLEEP” to OFF.
4.3. set “ HIBERNATE AFTER” to NEVER.
5. go to “DISPLAY”
5.1. set “TURN OFF DISPLAY AFTER “ to NEVER.
Press APPLY and then OK .

>>>3rd Way: {(THIS IS A VERY RARE CASE)} Any external hardware can cause this (like a keyboard or mouse can cause system to sleep to save the power )
1. To change this go to “MANAGE ” by right clicking on the “MY COMPUTER “ icon on the desktop .
2. Go to DEVICE MANAGER.
3. Click on the keyboard or mouse or any other USB devices and right click on them and go to PROPERTIES and select POWER MANAGEMENT and untick the appropriate box.
