Having problems with your Dell Dimension 5100 (D51L1) PC Desktop ?

All the cords are connected but there is no power going to my tower so it doesn't turn on


Answers :

Hi,
If there is no power getting to the motherboard and there is no indication of life, no LED lights or response when you press the power button then chances are that your PSU (power supply unit) has failed and needs to be replaced.
Now with Dell machines power supplies are slightly different to normal PSU's so you will need to get one from Dell themselves or get one from a Dell machine or eBay.


Regards.
1. check your power cord if its working properly, replace it and see if it works.\015\0122. the SMPS(Big fan at the back of computor) may not be functioning properly. another this is that there is an SMPS on/off switch chsk if that is on.\015\0123.if the first two steps are fine then there your cables may not be connected inside with the mother board\015\0124. it may also be because of your power button with may have a problem, which may be because of loose conection with the motherboard or it must be damaged.
