Hello. I am fairly new to the world of homebuilt systems and had just completed putting together a fairly midrange 1500ish system for gaming roughly a month ago only to have it stop working completely on me. The LEDs on the front panel do light up when the system is connected but nothing happens whatsoever when the start button is depressed on the case. I have replaced the power supply that was under warranty but apparently that was not the problem. I have swapped in a new mobo but with also the same results. I apologize if this is in the wrong forum but any advice as to what to look into next would be great.
I've never hit a wall like this in troubleshooting before. Absolutely nothing occurs when the start button is pressed. These troubles started after a routine network card installation. The computer would hang in the bios and give a beep code that consisted of a series of rapid beeps (no long beeps) and then turn off only to attempt to boot again. After a few rounds of this I killed the power via the front button pressed for an extended period of time and checked components. The gigabyte manual states that this beep code is a generic power failure error (though I'm unclear as to whether or not there was a long beep at the beginning that would change the error completely).
Again I apologize if this is posted in the wrong forums. I can be more specific with components if necessary, but since the computer is failing at such an early state I am assuming that this is not monitor/ram/HD related.
Thanks for the replies. I have tried reseating and replacing the ram as well as removing the network card. The unit is completely bricked. I can't get so much as a flicker of the processor/case/PSU fan. Absolutely nothing happens when the power button is pushed
What make/model PSU? That is a high power video card, needs high quality PSU, not no name lightweight PSU. To trouble shoot, Remove everything except CPU and heatsink. Remove motherboard from case and set up on a newspaper, magazine or piece of cardboard. Connect PSU and speaker. Start by shorting power header with screwdriver blade, should give 'no memory beeps. If not, is motherboard, PSU or CPU. If beeps, start adding things back to ID the problem.
The PSU's that have been swapped in to try have been a corsair HX520w that worked fine for the longest time as well as an Antec truepower trio 550w PSU. I've checked about the start switch by using the reset switch instead with little/no response. Will try the mobo and the PSU by themselves when I can get off of work here in a bit.
