abscheele Posted July 29, 2008 Share Posted July 29, 2008 I have already tried a difrent power supply, but any other ideas on how I may begin trouble shooting? thanks, Alec Link to comment https://www.insanelymac.com/forum/topic/118261-just-built-my-first-computer-and-it-wont-boot/ Share on other sites More sharing options...
m16 Posted July 29, 2008 Share Posted July 29, 2008 Does your motherboard's internal light turn green when plugged into the PSU (and the psu is on) ?

adamsweeting Posted July 29, 2008 Share Posted July 29, 2008 Need more details... Can you get into the BIOS? Are the hard drives spinning up? Do you have your internal speaker wired up? - Does it beep when you power on?

abscheele Posted July 29, 2008 Author Share Posted July 29, 2008 OK so I have it pluged in to a working electrical outlet(tested it with a lamp) flip the powersupply switch to the on position, it makes a slight noise. Then I push the power button on the computer and nothing happens. The harddrives do not spin up. I dont have an internal speaker connected but I will connect it and try again. Is this normal or when you guys built your computers did they boot up the first time you pushed the button? I also was just reading a tourtorial to building computers and realized I didnt use the standoff's(I think thats what there called the little screw type things that screw into the case then you attach the motherboard into them. Could this be the problem? thanks for the help, Alec Link to comment https://www.insanelymac.com/forum/topic/118261-just-built-my-first-computer-and-it-wont-boot/#findComment-837850 Share on other sites More sharing options...
cat_7 Posted July 29, 2008 Share Posted July 29, 2008 IF you didn't use those, you might have already toasted the motherboard through a short circuit. Take it of the current, take the motherboard out and put those placeholders in there and re-attach the motherboard and give it another try. Also check if you connected the powerbutton connector correctly.

MacUser2525 Posted July 29, 2008 Share Posted July 29, 2008 OK so I have it pluged in to a working electrical outlet(tested it with a lamp) flip the powersupply switch to the on position, it makes a slight noise. Then I push the power button on the computer and nothing happens. The harddrives do not spin up. I dont have an internal speaker connected but I will connect it and try again. What kind of power supply do you have? Is this normal or when you guys built your computers did they boot up the first time you pushed the button? Well when I build a computer it gets tested outside of the case by placing just one stick of ram in the board, the video card and processor. Now you connect the power supply to it and use a screw driver to just tap the two pins on the board that connect to the front power switch to simulate a button push. This best done with the whole thing sitting on the motherboard box with the anti-static bag underneath the the assembled motherboard, you may want to consider this as well. I also was just reading a tourtorial to building computers and realized I didnt use the standoff's(I think thats what there called the little screw type things that screw into the case then you attach the motherboard into them. Could this be the problem? thanks for the help, Alec Some motherboard trays/bottom of the cases have little bumps in them that are used in place of the standoffs so sometimes they are not necessary and if they were necessary then your cards that you put into the board would not seat properly so you know right off if screwed this up. In short the best thing to do take the board out of case test to confirm boot in stripped down configuration if it boots put it in the case test boot again with all the front panel wires connected testing the reboot button as well. Put all the sticks of ram in test boot again if this passed then connect up hard drives confirm they spin up looking at the HD Led to make sure it blinked to confirm that works if not shut down turn its cable around that connects to the motherboard. Once these are working put in any extra cards one at a time confirm boot and detection looking at the boot screen for the IRQs that get assigned while it tells you the type of card it is. Now once you have all this working to post error telling you it cannot find the OS get out a copy of Memtest86 and let it run through one pass to confirm your memory works at the default settings without any errors. When this is done you are now ready to install an OS on the machine and do further testing with something like Prime95 to confirm the machine is stable at 100% load using the default settings.

abscheele Posted July 29, 2008 Author Share Posted July 29, 2008 this is the power supply/case I am using: http://www.newegg.com/Product/Product.aspx...N82E16811156074 Link to comment https://www.insanelymac.com/forum/topic/118261-just-built-my-first-computer-and-it-wont-boot/#findComment-837946 Share on other sites More sharing options...
MacUser2525 Posted July 29, 2008 Share Posted July 29, 2008 this is the power supply/case I am using: http://www.newegg.com/Product/Product.aspx...N82E16811156074 Well it says 450w with 21a on a single 12v rail which in theory I think should be enough to run your parts provided that they are actually true ratings and from the one view where I can get a good look at the bottom of the case tray looks like it has the raised bumps so there should be no need for stand offs. So as I said before it is time to take the board and power supply out of the case and test bare bones configuration then proceed step by step connecting everything up.

Orea Posted July 29, 2008 Share Posted July 29, 2008 Sounds like you've fried your board. Try it on the antistatic bag outside the case like Cat said. If that doesn't work still, attempt another PSU or quickly report to NewEgg DOA.
