I just purchased a Compaq Presario SR5310F tower and i have it plugged into the vga plug in my hi def monitor with a SVGA monitor cable. The problem i'm having is when the loading screen pops up my monitor goes blank and "No Signal" scrolls across the screen. i have tried to go in through every possible way i could to figure out the problem but i just end up with the same result. my buddy said its either 3 things: the tower itself is bad, the hard drive is bad, or its trying to read or set up kernels and it cannot. has anyone ever had this problem? could it be my monitor. it's nothing spectacular just a 19" flat panel hi-def tv/monitor with 720p resolution. i know my explanation may be a little vague so if there is anything you need more info feel free to ask, i'll answer to the best of my knowledge.
