This is one of the best practice to troubleshoot SYSTEM BOARD

1.Reset the bios
2.Check the power supply
3. Make sure you didnt over tighten the screws.
4. Make sure that the mb standoffs are only in the places where there are holes. if not it can short the Motherboard.
5. Check for loose screws
6. Verify in the manual that the Power Switch is on the correct pins
7. Verify that the switch works. You can do that by finding the pins where the power switch connects and then take a screwdriver and touch both of the pins (dont worry it will not shock you)
8. reseat all cards and memory
9. Unplug all fans, cables and cards from the motherboard. Only have the powerswitch, powersupply and cpu fan + memory hooked up. then try to post (this will eliminate the possibility of other things shorting out the mb)
10. As a last resort remove the motherboard from the case. and Only have the powerswitch, powersupply and cpu fan + memory hooked up and try to turn it on. (this will elimate the possiblity of having the case short out the mb)

if all above don't resolved your problem. then listen to this one last resolution, removed all parts from motherboard unscrew it all and removed all funs,memory,vga,cmos battery and process from motherboard. then get a paint brush and kerosene gas and was only the board removed any dirt on it and clean it carefully after cleaning it you must hang-it on tobe airdry for few days (3-4) air dry only. note: handle your memory with care handle only at the pvc or board do not touch any pins that well create an electric static that well destroy any electronic parts on the computer like memory.

after few days: assemble all it back (but let it set on a table first do not place it on the casing) to isolate MB short.
for first just place the power button switch then Make it POST....

if it displays! then great .... continue assembling..

otherwise: if it dost not display then you check for physical blown capacitor on motherboard if none, check power supply , memory or vga try to isolate each parts for problems.


nice advice ' i like it !


is water advisable to use to clean up your pc?


@ freddie

you can use water based cleaners for the CPU casings but for electronics parts dont use water you can use wd40 to clean up electronics parts of your pc. Thanks.
