I recently bought all the parts to build a new pc and when i finally get everything to turn on, it doesnt connect to my monitor(it only responds with 'no signal'). I've already asked this question but with no avail, so I'll put a lot more detail into this one.

SPECS:
Gigabyte 78LMT-USB3 Socket AM3+ MotherBoard
Phenom II X4 965 Processor
3 TB hitachi Hard Drive (been used before)
Radeon R7 240 2GB DDR3 msi Graphics Card
Evga 430W Power Supply
2 4GBs of RAM
DiyPc Microatx case

Just so anyone knows I've already done that post question thing that everybody links and it didnt work for me. I've already tried 1. Taking out my graphics card and plugging hdmi/vga into motherboard. 2. plugged hdmi/vga into graphics card only. 3. taking out my RAM and booting and I hear zero beeps(yes i have a speaker installed). 4. I checked my motherboard manual and made sure the RAM is in the right spot. 5. switching the cpu and still same problem. 6. plugging a different pc to my monitor and it worked. 7. I've tested the current cpu im using in another pc and it works as well. 8. Taken the battery out and let it sit for a minute. I dont believe its the power supply because ALL the fans power on as well as the LEDs whenever I press the power button. For anyone going to say to do something in my BIOS I cant because I dont even see the menu when i start the pc. I've connected my pc to a different monitor and still the same result. I'm sorry if this comes to you as offensive but Im just really sick and tired and I've done about everything I could think of(including taking apart my entire pc several times). So I just hope someone can help me with this because Im thinking about returning everything I bought and to start over

look in CH5, troubleshooting. There will be a list of possible beep codes and their meaning.

P.S. This info should be in your motherboard's manual.

to make it simplier i built a new pc and it turns on fine but it wont connect to the monitor using the hdmi cord or the vga cord. And i tried many solutions from other arcticles and none have suceeded.
 
Is this the post you are referring to:
http://www.tomshardware.com/forum/261145-31-perform-steps-posting-post-boot-video-problems
If so, what are the results of EACH step in the list? Since we can neither see nor touch your PC, the results of each step are very important in allowing us to eliminate common problems and give you a diagnosis that is other than guesswork. Telling us that you worked the list WITHOUT giving us the results gives us no information. Help us to help you!

This will take a while since im on my phond

1.Did you carefully read the motherboard owners manual? Yes, all the way to the end several times

2. Did you plug in the 4/8-pin CPU power connector located near the CPU socket? If the motherboard has 8 pins and your PSU only has 4 pins, you can use the 4-pin connector. The 4-pin connector USUALLY goes on the 4 pins located closest to the CPU. If the motherboard has an 8-pin connector with a cover over 4 pins, you can remove the cover and use an 8-pin plug if your power supply has one. This power connector provides power to the CPU. Your system has no chance of posting without this connector plugged in! Check your motherboard owners manual for more information about the CPU power connector. The CPU power connector is usually referred to as the "12v ATX" connector in the owners manual. This is easily the most common new-builder mistake. Yes, my psu has a 8 pin plug and i connected it.





3.Did you install the standoffs under the motherboard? Did you place them so they all align with the screw holes in the motherboard, with no extra standoffs touching the board in the wrong place? A standoff installed in the wrong place can cause a short and prevent the system from booting. Yes, i made sure everything was where its supposed to be.




4.Did you verify that the video card is fully seated? (may require more force than a new builder expects.) I had to adjust the case a bit using some tools but i got it to fit and i hear the click.

5.Did you attach ALL the required power connector(s) to the video card? (some need two, some need none, many need one.) It is best to use cables connected directly to the PSU. Only use adapters if absolutely necessary. Mine does not have a pci outlet to connect to.




6.Have you tried booting with just one stick of RAM installed? (Try each stick of RAM individually in each RAM slot.) If you can get the system to boot with a single stick of RAM, you should enable an XMP profile or manually set the RAM speed, timings, and voltage to the manufacturers specs in the BIOS before attempting to boot with all sticks of RAM installed. If your motherboard supports XMP profiles that is the best way to get your RAM running at its rated specs. Nearly all motherboards default to the standard RAM voltage (1.8v for DDR2 & 1.5v for DDR3). If your RAM is rated to run at a voltage higher than the standard voltage, the motherboard will underclock the RAM for compatibility reasons. If you want the system to be stable and to run the RAM at its rated specs, you should either enable an XMP profile or manually set the values in the BIOS. Many boards don't supply the RAM with enough voltage when using "auto" settings which causes stability issues. Yes, i put the RAM in every slot and replaced it and tried again to no avail. I cant open the BIOS because it wont connect to my monitor.

7.Did you verify that all memory modules are fully inserted? (may require more force than a new builder expects.) It's a good idea to install the RAM on the motherboard before it's in the case. Yes, i pushed it in enough that the two sides clicked and is properly holding it down.

8.Did you verify in the owners manual that you're using the correct RAM slots? Many Intel motherboards require RAM to be installed in the slots starting with the one further away from the CPU. Yes, mine works similier to this and i put the RAM in the slots my manual told me too. I also tried putting it in the second slot the manual said i could do.

9.Did you remove the plastic guard over the CPU socket? (this actually comes up occasionally.) Yes, one of the first things i did.



10.Did you install the CPU correctly? There will be an arrow on the CPU that needs to line up with an arrow on the motherboard CPU socket. There may also be a notch that will only line up in one direction. Be sure to pay special attention to that section of the manual! Yes, the cpu sildes right into the socket and fits perfectly.




11.Are there any bent pins on the motherboard/CPU? This especially applies if you tried to install the CPU with the plastic cover on or with the CPU facing the wrong direction. No, not that i know of atleast. I accidently bent a couple pins while taking it out once but i fixed them using a pocket knife and even used my old pc to test if it still worked, and it did.



12. If using an after market CPU cooler, did you get any thermal paste on the motherboard, CPU socket, or CPU pins? Did you use the smallest amount you could? Here's a few links that may help: I put enough thermal paste that the entire cpu was covered but only the lightest layer.

plugged in? Some motherboards will not boot without detecting that the CPU fan is plugged in to prevent burning up the CPU. Yes, the cpu fan is plugged in and working.



14. If using a stock cooler, was the thermal material on the base of the cooler free of foreign material, and did you remove any protective covering? If the stock cooler has push-pins, did you ensure that all four pins snapped securely into place? (The easiest way to install the push-pins is outside the case sitting on a non-conductive surface like the motherboard box. Read the instructions! The push-pins have to be turned the OPPOSITE direction as the arrows for installation.) No, i didnt use a stock cooler. which im assuming is a heat sync.




15. Are any loose screws laying on the motherboard, or jammed against it? Are there any wires run directly under the motherboard? You should not run wires under the motherboard since the soldered wires on the underside of the motherboard can cut into the insulation on the wires and cause a short. Some cases have space to run wires on the back side of the motherboard tray. No, no wires are under the motherboard and i made sure no nails were left inside.

16.Did you ensure you discharged all static electricity before touching any of your components? Computer components are very sensitive to static electricity. It takes much less voltage than you can see or feel to damage components. You should implement some best practices to reduce the probability of damaging components. These practices should include either wearing an anti-static wrist strap or always touching a metal part of the case with the power supply installed and plugged in, but NOT turned on. You should avoid building or working on a computer on carpet. Working on a smooth surface is the best if at all possible. You should also keep fluffy the cat, children, and fido away from computer components. Im pretty sure its fine, i was on carpet for a bit but i made sure to constant touch the case side panel before i touched any parts like the cpu, motherboard, etc.

17.Did you install the system speaker (if provided) so you can check beep-codes in the manual? A system speaker is NOT the same as normal speakers that plug into the back of the motherboard. A system speaker plugs into a header on the motherboard that's usually located near the front panel connectors. The system speaker is a critical component when trying to troubleshoot system problems. You are flying blind without a system speaker. If your case or motherboard didn't come with a system speaker you can buy one for cheap here: Yes, i have one installed and i tested it when i was installing the cpu without the fan and it started beeping(this was before i tested the cpu with the other pc so its not fried).



18.Did you read the instructions in the manual on how to properly connect the front panel plugs? (Power switch, power led, reset switch, HD activity led) Polarity does not matter with the power and reset switches. If power or drive activity LED's do not come on, reverse the connections. For troubleshooting purposes, disconnect the reset switch. If it's shorted, the machine either will not POST at all, or it will endlessly reboot. Yes, this is one of the connections i checked multiple times making sure its in the right position.




19.Did you turn on the power supply switch located on the back of the PSU? The switch should be depressed on the side with a I, the O means off. Is the power plug on a switch? If it is, is the switch turned on? Is there a GFI circuit on the plug-in? If there is, make sure it isn't tripped. You should also make sure the power cord isn't causing the problem. Try swapping it for a known good cord if you have one available. Yes, i remember to switch the button and ive tried a different cord as well as plug it into different outlets.



20.Is your CPU supported by the BIOS revision installed on your motherboard? Most motherboards will post a CPU compatibility list on their website. Yes, i double checked with a benchmark test, pcpartpicker i think the name is.

21.Have you tried resetting the CMOS? The motherboard manual will have instructions for your particular board. Yes, i have and still no effect.


22. If you have integrated video and a video card, try the integrated video port. Resetting the bios, can make it default back to the onboard video. If you are trying to use HDMI outputs, try using DVI or VGA instead. Sometimes the HDMI ports won't work until the correct drivers are installed. I dont have a DVI cord unfortunately but i have tried both hdmi and vga.

23. Make certain all cables and components including RAM and expansion cards are tight within their sockets. They are.


Hopefully that helps you guys.
 
In reference to step 17, the system speaker, on a normally functioning system there will be one beep to signify a successful POST. Do you receive that beep? If not, what exactly were the beep codes you got? If you do, indeed get the single beep, then we have to start looking elsewhere. After step 23, there are additional troubleshooting procedures. Have you done any of them?
 
What beeps did you get? If you received NO beeps, then there is a problem with either the motherboard or the CPU, possibly with the PSU. I would start with the PSU second choice would be the motherboard, and last the CPU.

With the processor im not 100% sure but i think it was 5 beeps since i didnt have the cpu cooler plugged in. As for the psu i tried it with my old pc and it worked fine. And since i already tested the cpu it must be the motherboard.
 

five equal beeps, or a mixture of long and short beeps? If a mixture, then what order were they in? Differences are critical here!

Im pretty sure it was 5 really quick beeps. However, i realized that i tested my processor in my other pc which gave the beeps. And since this one isnt giving any beeps at all it may be a psu issue. Though im pretty sure i plugged in the 12V and the main power connector.
