This is my first build. I put it all together and it there was no video at all. I checked my vga cables to make sure and they were plugged in and fine. Afterwards i googled past post and found out about the boot test, took it apart and did a boot test. The system appears to boot up, cpu, video card and all fans turn on along with mobo led.

I also tried using only one ram card and no ram card at all. the mobo doesnt beep at all.

i tried taking the mobo battery out for a few minutes and putting it back in but still no luck. My PSU is connected using the 24v and the 8 pin, tried booting up without the video card as well but still the same result. any idea?

Are you able to access the BIOS? Sounds like your motherboard is DOA otherwise. Just because things are spinning does not mean the system has booted, it just means that power is getting to your devices.

I suggest you try to start the system with no devices installed or attached (disconnect optical and HDD). With only the video card and memory installed, verify that the system will allow you to access the BIOS. If so, shutdown and add the optical drive back to the config and try again. Use the same process of adding things back until you add something and it fails.

The idea is to isolate the problem.

Good luck!

i tried with only the memory and video card and still no luck at all. just in case the mobo is DOA any recommendations for a better one? (came into some cash, might as well get a better one if i can)

Depending on your budget, this is a nice board:

An even better (and costly) board is (I have this one and am very happy with it):

Motherboard opinions are like rear-ends. Every body has one and they all stink!

Lots of opinions out there. Set your budget and then proceed. Newegg.com is where I go to buy all my stuff. I highly recommend them if you are in the US or Canada.

Good luck!!!

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 beep 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.

Make sure you plug the CPU power cable in. The system will not boot without it.

I always breadboard a new build. It takes only a few minutes, and you know you are putting good parts in the case.

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:
Running fans and drives and motherboard LED's do not necessarily indicate a good PSU. In the absence of a single short beep, they also do not indicate that the system is booting.

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.
