Hi there, I have spent hours searching for an answer to this problem, hoping someone can shed some light.
Details:
Asus PTGD1-LA Grouper GL8E in a Compaq Presario SR1239UK.
Intel 915G, P4 515(P) 2.93Gb 533MHz
Socket LGA 775
RAM: Elixer 1Gb PC3200U 400MHz
Cooler: Taisol fan w/large round heatsink with copper core.
Problem: No Post, No display, No Keyboard.
Symptoms:
Monitor blank, on/off led remains on standby, no response.
Keyboard PS/2 lights flash once on power up then does not respond. Tried a USB keyboard, same thing.
Hard drive formatted only, but light comes on briefly, then CD lights briefly, (draw will open and close if asked).
Tried:
I have tested the monitor and KB on another PC. Have removed everything connected to MB, removed MB from case, reset bios removing CMOS battery moving CLCMOS jumper for 10 secs and more.
Have removed power,disconnected everything including the RAM, pressed power button for 5 secs to discharge MB, three times in a row. (This action changed the fan speed to max on the third power up).
Removing the RAM, on starting gives long 10 sec beeps, no other times are there any beeps.
There are no obvious signs of component failure, MB is very clean, PS has slight dust on fan.
AS it has onboard VGA out, tried a Cirrus Logic video card, still no response.
Have not removed the heatsink or processor, because I believe I need some paste to reseat them.
Questions:
Is it the MB or a processor failure. ?
What is the next test to do ?
Whats the best chip/ heatsink paste. ?
Have I missed something simple. ?
Do I just give up and buy a MB and pro combo. ?
I would be gratefull for any suggestions,
First post, with thanks to a great forum. I have learnt loads.
