Still no beeps

Hello, I was putting together my build a couple of weeks ago, and the motherboard didn't give any beeps (speaker was in, went through the trouble shooting guide), which I was told that meant that it wasn't working. So I RMA'd it, and now I have a new one. I have the exact same issue. The Dr. Debug still reads 00 (which means it should be working, this is on ASRock boards), but it still does not post. What else could be the issue? Please help.

Thanks.

Oh, if it means anything, I put it on a piece of cardboard to diagnose any problems before I put it in the case. That was a big hassle last time.

Hey!

Have you tried booting with minimum hardware? Take out anything that isn't necessary and see what happens.

Yes, still no boot. 1 stick of RAM, the video card, CPU, 1 HD.

By the way, here's a list of my hardware:

New list:

Optical Drive (Mine is actually kind of loud, I figured a new one might be in order)

Case and Filters

Mobo (Still not had any comments on this, is this the one to go with? I do want to overclock. Is $90 too cheap for a mobo in a non-budget build?)

GPU (The better cooling and higher OC are worth it to me)

Fan/Heatsink and Thermal

Memory (No comments on the memory brand, just amount, but I want to stick with 8GB)

CPU

SSD

PSU (I already own this)

Also cool, since I posted this, the Mobo has fallen $10 in price, and the CPU $30. Still curious if the GPU will fall in price if you know about that.

Thanks for all your help :)

Does it make sense to put it together and take it to a professional to look at? I've built a computer before and didn't have this problem before, but a professional might know how to fix it.

Work through our standard checklist and troubleshooting thread:
http://www.tomshardware.com/forum/261145-31-read-postin...
I mean work through, not just read over it. We spent a lot of time on this. It should find most of the problems.

If not, continue.

I have tested the following beeps patterns on Gigabyte, eVGA, and ECS motherboards. Other BIOS' may be different.

Breadboard - that will help isolate any kind of case problem you might have.
http://www.tomshardware.com/forum/262730-31-breadboardi...

Breadboard with just motherboard, CPU & HSF, case speaker, and PSU. You do have a case speaker installed, right? If not, you really, really need one. If your case or motherboard didn't come with a system speaker, you can buy one here:

You can turn on the PC by momentarily shorting the two pins that the case power switch goes to. You should hear a series of long, single beeps indicating memory problems. Silence indicates a problem with (in most likely order) the PSU, motherboard, or CPU.

Remember, at this time, you do not have a graphics card installed so the load on your PSU will be reduced.

If no beeps:
At this point, you can sort of check the PSU. Try to borrow a known good PSU of around 550 - 600 watts. That will power just about any system with a single GPU. If you cannot do that, use a DMM to measure the voltages. Measure between the colored wires and either chassis ground or the black wires. Yellow wires should be 12 volts. Red wires: +5 volts, orange wires: +3.3 volts, blue wire : -12 volts, violet wire: 5 volts always on. Tolerances are +/- 5% except for the -12 volts which is +/- 10%.

The gray wire is really important. It should go from 0 to +5 volts when you turn the PSU on with the case switch. CPU needs this signal to boot.

You can turn on the PSU by completely disconnecting the PSU and using a paperclip or jumper wire to short the green wire to one of the neighboring black wires.

This checks the PSU under no load conditions, so it is not completely reliable. But if it can not pass this, it is dead. Then repeat the checks with the PSU plugged into the computer to put a load on the PSU.

If the system beeps:
If it looks like the PSU is good, install a memory stick. Boot. Beep pattern should change to one long and several short beeps indicating a missing graphics card. Silence or long single beeps indicate a problem with the memory.

Insert the video card and connect any necessary PCIe power connectors. Boot. At this point, the system should POST successfully (a single short beep). Notice that you do not need keyboard, mouse, monitor, or drives to successfully POST.

Now start connecting the rest of the devices starting with the monitor, then keyboard and mouse, then the rest of the devices, testing after each step. It's possible that you can pass the POST with a defective video card. The POST routines can only check the video interface. It cannot check the internal parts of the video card.
