i have a compaq presario 5310us with a tr100 motherboard in it......the computer was working fine and then all the sudden i turned the computer on and there is no video.......the fans and cpu fan all turn on , but, there is no beeps or anything. like it aint even posting. this computer has onboard video on it. so i tried a pci video card in the slot and the monitor screen still does not come on. also, on the keyboard the numlock light flashes at a steady beat. ive tried clearing the cmos and new battery, new sticks of memory,other power supplies,other monitors as well and all to no avail. if anybody has some tips for me to what could be causing this i would greatly appreciate your advice. thank you for all of your help.
