New Build Problems

post #1 of 8
Thread Starter 
So I put together my sig rig yesterday and it will not boot and I can smell something burning from the top vent of case. I pop it open to find out I didn't have the 8pin connected so proceed to power back on. Again smell something burning and no lights on the board. The standby and DDR came on at first but nothing. I take board out of case and put it on the box and power up but again nothing. No lights on the board but no burning smell either. I already RMA'd the board and cpu since I had a MB standoff in the wrong spot and from another thread it seemed like this was the problem.

However I decided today to take my Sig PSU (Corsair 750TX) and put it in my old P2 400mhz machine that is still running. I put PSU in that machine and flip the PSU switch and it powers on the fan in PSU and case fan and HDD then turns off. This is before pressing any power switch. No response from pressing power switch. Take it out and plug back in the old 200w that came with machine in late 90s and it works like a charm.

Could it be my PSU that was bad or went bad and I should be returning it as well? Or is the PSU not compatible with the old board? It is a 20+4 pin psu and a 20pin MB connector. Really trying not to run into problems next time around.

the standoff in the wrong place, if it shorted on the mobo, you most likely cooked the mobo, and possibly damaged the psu - but its kinda hard to say for sure. If youve rma'd the board I'd rma the psu as well and start fresh. This time triple check the stand offs. As far as the new psu in the old box, I am fairly certain the original 20 pins are the same across atx specs, and the +4 (24) were added later, so it should have worked. Double check that tho.

good luck

How can you put the mobo stands in the wrong place? I can't figure it out unless by that you mean you forgot to put them on.

I hope your RMA goes well. Don't fret too much.

I think he means he may have put one in the wrong hole altogether, forgot it was there when seating the mobo, so now he has a standoff up against the mobo, not in a place where there is a hole in the mobo for it, and now he cant see it either. power on....

I usually spend a good half hour studying where all the mobo standoff holes are and where they mount on the pan, then I test fit a bunch of times, and count them all off, making sure none are missing, and none are in the wrong pan hole - which is probably what he didnt do

I had an Asus p4p800 board in the case and when I put in the standoffs for it I had one in the wrong spot at the bottom and left it and was fine. So this time I put the DFI board in and forgot one was out of place on the bottom even though I added another on the bottom. It just never crossed my mind to remove it since it was fine with the other board. I guess I got in a hurry to get it together, running, and all my stuff installed so I can be ready to go Saturday.

Not sure how many of you folks have ever RMA'd through buy.com but all I want to say is that after RMA'ing to newegg and buy.com at same time, I'll be shopping at newegg from now on. Both received my stuff same day. Newegg will have my replacement board and cpu here today and buy.com still has not acknowledged that they have received my PSU. Both received my stuff Thursday June, 12th at around noon EST. How can buy.com be so behind? Anyone with half a logistical brain could have a system set up to have returns processed within 48 hours of receiving them.

Guess I should have just sent it to Corsair...
