Maximum PC

Nothing shows on the screen when I press the power button on my computer. I recently put an old desktop back together to give to a friend who needed it for college this semester, but I can't figure out why it's not posting.
The fans and everything work fine when it's powered on, yet the screen is blank. I'm trying to find the model number of the motherboard for ease of helping.

Thanks

Ok, I cannot find a clear CMOS button, nor can I find the jumper, but I did try the whole battery trick and nothing changed.

Why do you apparently suspect the MB?

Newegg

EVGA 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 bit and service pack installed.]

If that fails, this link provides a comprehensive list of what to do when the new PC won't post:

Does this mean if a Linux or Win OS disk is in the ODD it will start to load up? Because if yes, then it is likely a video problem.

The monitor is receiving no signal from the video out.

I'm doing the external build idea now. I've tried everything else that's listed.

If all else fails, then I guess it'll be time to buy new parts for the desktop and my friend will be SOL.

So far no good.
Quck question though, will my motherboard post if my CPU is completely blown?

No. It's extremely rare, however, that a CPU comes DOA (you might as well play the lottery if you have DOA processor, basically) and any time a CPU is busted prematurely is usually due to user error.

well... I DID just turn 21 And I DID do great at the casinos when I went.
Thanks for everyone's help/advice btw, I'm going to keep trying tomorrow and if I can't get anything working, then I'm going to just scratch the whole thing.

One more question: Do you receive any beep codes when you try to get the motherboard to post? If not, it is most likely a failed motherboard.

It could be a power issue too.

Sorry for the delayed response. Classes started back Thursday.
No, I have only gotten a really long beep one time. Other than that, the motherboard has been completely silent.
