Computer powers on - monitor doesn't display

NoCola - Jan 10, 2012 at 12:30 PM
My desktop computer(Compaq Presario SR2030) turns on, but the fan continues to run without the monitor displaying anything. I have searched the internet several occasions reading about the same problem others have been having. I checked the power cord, I tried holding the power button for 30 secs to a min, I removed the battery (worked, but then the mouse and keyboard wouldn't work), the CMOS, cleaned out the dust, removed video card--NOTHING. I tried the pushing F8 button suggestion and holding the sleep button down, but I still get nothing from the monitor. What else can I try?
