hi experts,
i have mother board Abit-NF7 V 2.0,
i was unaware of one capecitor 100Mf 25V near RAM slot was OPEN(fired)
dut to that( I guess but not sure) one another part the 8 legs IC ( i m not sure for IC or mosfat or what....)
digit written on it is " IOR402C- 7K8E F7313" burnt right away
now mother board not booting or anything .....
can any one guide me regarding equivallant of IC or easy to available at which place ??
or is there any equipment where this IC belongs so i can try it with my MOBO...
i chack several mobo but there is no same IC , i think it use only in DDR RAM slot .... although you expert can suggest something how to manage this ???

picture attached for more information

Could you clarify what the problem is with? The IC or the Capacitor?
Also, you said there was a fire on that chip? When did you notice this?
Last, what's the specs of this system, including the power supply?

thanks for reply...
I have power supply 450Watt working fine
Processer is AMD Athlon XP 2500+ mobile ( Barton core)
1.5 GB DDR RAM 3200+ 400FSB
60 Gigz HDD

it was not booting so i open cover and trying to do it at that time
i noticed that capacitor was pinched and pressed ( i think it was since long time when this system was assembled but may be long use it is damage now a days) but i did not take that seriously
than pull out RAM and put it back again
as i power on ..... that IC got excessive heat and over the top it got red , little SMOKE and black spot on it.....
stilll if i on power IC get Very HOT..... system is not booting alll fan and everything is working but NO disply.... on Monitor.... i chack AGP card another system it is working fine too....

after this incident i changed capacitor (i got it from another mother board) but now IC is damage so problem is with IC .... i am looking for same number or equivallant or any IDEA ....

thanks

that must b a problem with ur MOSFET.... even i had the same problem with my ASUS board.... MOSFET wud have burnt...dont worry... its easily available...or u can also go to any mobo service centre and get the MOSFET replaced for free... i am sure they wont charge u anything cos its such a cheap one... neways... chk it out...

you gave your own answer your only solution is to buy a new mobo and hope for other parts not to be burned (if your voltage regulator isn't a good quality one)

btw change the whole system if you can

athlon x2 3800 or core2duo 4300 will be even better choices than buying only a new mobo for your old cpu
