Question about ASUS A7N8X-E Deluxe NForce 2 Ultra 400 Motherboard (90M7A770GOUAYOZ)
What happened was i started my PC on christmas eve and10 minutes to it being on, i heard a loud bang and i could smell smoke, and all the electrical products knocked off, due to having a fuse box downstairs and when i lifted all the fuses back up the other electrical products came on apart from the pc at all, there was no light, no power coming from the power supply at all, the previous power supply i had was Esac ATX switching power suppl Model No PIV-500-2 It has AC input 115/230V~8/4, 5A, 50 - 60HZ, Output 400W Max, +3.3v & +5 Combined Load 240 W, + 3.3V, +5V & +12V Combined Load 380W, The New Power Supply I changed it for, Winpower Switching Power Supply Model ATX-400 , Max Output is 400W,
115V AC +12V 18A MAX
7A MAX +5V 25A MAX
60HZ +3.3V 18A MAX
230VAC -12V 0.3A MAX
50HZ +5V 15B 2.0A MAX
Please can you advise what i need to do to get my computer to work do i have a get a new motherboard or not. The Motherboard i got is ASUS A7N8X-E DELUXE.
New power supply looks okay; in terms of specs.
Sadly, when a system takes a direct voltage spike like the one your experienced, the motherboard often takes the brunt of the power spike emitted by the failing power supply (the pop you heard).
I you have replaced the power supply, and the system still will not power on:
1) check physical connections to the board, all components are seated, power is in place to the board.
2) You have voltage from the power supply (assuming you know how to use a multimeter)
12v on the yellow (this can vary between 10.5-12.9)
5V on the Red (same variance of +/- .3 V)
Black shows a ground (voltmeter centers out)
3) Replace the Motherboard
I found your MB on E-bay between $34-$50

More than sure if you have replaced the power supply already and the computer still not working,there must be a electrical damage to the board.
it is sure that.but you have to check some other components too seeing that they are stuck in the board,like the procesor and ramm dims or the video card..the electrical charge may have affect them too.
but 1st thing to do is to change the mainboard..
oh by the way...just to be sure..try to make a bios reset..maybe it will work and pull out the ramms from the computer..put them back after...ussualy this works...
good luck and let me know about
