N15235 win fast motherboard


The main cause behind this problem is :-
1) RAM JAM
2) HDD is taking extra power from SMPS
3) Motherboard faulty Capacitors / ICs
Try following :0-
step 1) Remove CMOS Battery (3V battery) + RAM
and now try to check whether Fan shows same symptoms or not

Step 2) if results of above step is fail then try to remove HDD powersuppy + CD/DVD power supply + Floppy Power supply (in short provide power to only motherboard) and now start the system.

If the result are same
3) then look for any swollen capacitors on motherboard, if they are then you need to replace them.

4) If no capacitor is swollen then check for every bigger IC on motherboard for whether it got excessive heated or not. If yes then you need to do serious operations on your motherboard .
Please not here i have used the word EXCESSIVE HEATED. and noth the normal heated
