I'm putting together a PC using a 865DGH motherboard from Intel an Intel P4 3.1 processor along with the raidmax scorpio which comes with a 480w power supply. I added a fan for the hard drive and the CPU fan. I put everything together but it won't turn on. I took everything apart six times, and i still have the same problem. This is the fifth computer i set up and i never had that problem before. One thing i noticed is that there is 4 pairs of connectors from the case ( power s.s, reset, H.D.D.). The fourth (unlabeled) one is connected to the power supply. I'm almost positive that there was suppose to be an (on/off) connector also but there wasn't ( maybe it's the unlabeled one). I checked my local store and there are all the same. I even asked the sales associates and there were as clueless. Any suggestions please. Thanks.

Re: Raidmax Scorpio ATX Mid-Tower Case
The on/off connector is the power labelled one.
The one thing you may have to do is (if you have'nt already)connect the power connector from the PSU to the processor power supply, close by to it as it may not just run off the motherboard ZIF socket for it's power up.

Most desktop computer cases have a range of standard mount holes, standard offs. I suggest you select a motherboard that suits your requirements. To be sure that the motherboard will fit your case, take the motherboard mount base with you to the computer shop and place the motherboard of your choice on the base to see if the mounting holes line up. You may need to upgrade the switch mode power supply to a higher power unit if the total power requirements is near the maximum the existing unit can deliver.
Here are some solutions:
1. Try to use some silicon oil in fan apertures to decrease rub
2. Try to manually (look for a mainboard's service software settings) decrease rotation speed if available
3. Less recomended: disconnect fan cable from mainboard and don't stress your computer (try not to overheat, - work with software that uses less resources) and buy a new one when available
Recheck the wiring. Make sure the fans are all plugged into the proper place. Then try reseating the RAM, video card, & cpu. Make sure you have applied a good thermal paste between cpu & heatsink as overheating can cause the system not to boot. Hope this helps & please remember to rate my answer. Thanks.
use a test pen and check if any power coming out from the power supply cable e.g. to hard drive, motherboard and so on.. this will help to to find out if it is actually power supply issue or components issue....
