Why do you apparently suspect the MB?NeweggEVGA support
To start out, GmsCool on Eggxpert has a concise checklist that I really like (and I have arrogantly made less concise) for a new build troubleshoot:
Make sure the 4
or 8 pin
power connector located near the CPU is plugged into the motherboard (MB) and it is fully seated.
Make sure the 20+4 pin main power connector is fully seated into the MB.
Make sure the PCI-E 6 or 8 pin power connector
is plugged into the GPU video card; if
the card has such a connector(s), and that it (they) are fully seated. [images of various power connectors
Make sure you used the standoffs
that came with the case to mount the MB and not have mounted it directly to the case. [note: Some inexpensive cases use raised nipples in the sheet metal for direct mounts instead which is OK as long as all
nipples correspond to mounting holes under the board.]
Make sure you used the rear I/O port panel that came with the MB, and not the one that came with the case. Make sure none of the little tabs have shorted out the ports.
Try one stick of RAM, and then another.
Make sure the CPU fan is plugged into the CPU_FAN header.
Try an External build
, tear it down to a minimal functioning system, lay the main board (helps if speaker connected to front header or embedded on MB for beep codes; or if any diagnostic LEDs, LCD are present) on a piece of plain brown cardboard or other non-conducting surface with only a Keyboard, one stick of RAM, CPU, HSF, PSU and monitor to rule out shorts as well as bad components. [Temporarily use onboard graphics if available otherwise use your video card.] Switch RAM stick and slot location. Add one component back at a time. This will rule out components and maybe rule in the defective part. If you have any known working parts that can temporarily substitute this is a good time to try them one at a time.
Please list all
of your hardware for more specific help. [List specific make and model number for every
component in system and attached to system and don't forget the case. If this PC is from a major PC builder, list the make, full model and complete model number too. List BIOS version too. Don't forget any parts you upgraded or are trying to install. Links
are greatly appreciated as they remove part ambiguity and why should we have to look them up
? Be sure to include the full OS version and
service pack installed.]
