My laptop is turned on, but there is no display.

Hey there,

About a year ago, I bought a laptop for my company. My laptop recently stopped operating, and I figured it was due to a Windows issue. When I turn on the power, the fan works for a few seconds and the lights turn on, but the display remains blank. I thought it was a RAM issue, so I cleaned it out, but the issue still exists? What are your opinion on the subject?
