Custom-built PC will not display anything

Ultra Ga-p55a-ud3 motherboard
March 2, 2010 at 19:33:21
Specs: Windows 7, i5-750/4gig
So i custom built a pc from parts that I got at
frys. However, even though i am 100 percent
sure that everything is kosher, at least
physically i am at a bit of a loss... as best i
can tell, since i have not loaded the bios in
yet, it cant see my graphics card and as
such, cant do anything.... what do i do?
there is no video outputs on the motherboard.
I have 4 gigs ram. i5-750 cpu and a radeon HD
5770 graphics card... thanks!

"since i have not loaded the bios in
yet, ..."

The bios is already ready to go !

ATX power supplies are always powering ATX mboards in some places, even when the computer is not running, as long as the power supply is receving live AC power.
Did you unplug the computer, or otherwise switch off the AC to the computer, at ALL times when you were installing components and connecting wiring ??

Markings on the mboard can be confusing.
Did you follow the directions in the mboard manual ??

What capacity does your power supply have ?

"radeon HD 5770 graphics card."

The video card has a socket on it an extra wiring connector from the power supply must be plugged into. Did you connect it ?

"450 Watt or greater power supply with one 75W 6-pin PCI Express? power connectors recommended (600 Watt and two 6-pin connectors for ATI CrossFireX? technology in dual mode)
Certified power supplies are recommended. Refer to http://ati.amd.com/certifiedPSU for a list of Certified products"

If you're a gamer....
In most if not all cases, the max capacity rating of the PS is an intermittant rating. It's recommended that you do not load your PS to any more that 80% of that rating if you are going to be using something that puts a constant load on it, such as playing a recent game for hours on end. In that case, you multiply the min capacity stated for the system with the particular video chipset on the card by 1.25 to find the min. capacity of the PS you should get.

450 x 1.25 = a minimum 562.5 watt capacity
two 5770 cards - 600 x 1.25 = a minimum 750 watt capacity
.......

Don't buy an el-cheapo PS.

" i5-750 cpu "

Your specific i5-750 cpu must be on this list
http://www.gigabyte.com.tw/Support/...

Blue highlighted numbers on the left are the Intel Part numbers.
If you click on the blue highlighted number, it shows you more info. Your i5-750 cpu must be one of those.
http://www.cpu-upgrade.com/mb-Gigab...
The mboard minimum specific bios version required for the i5-750 cpu s F4 - Gigabyte doesn't list any bios updates lower than F4, so your present bios version probably supports recognizing your cpu, unless you bought the wrong i5-750 model.
.....

"4 gigs ram"

That tells us nothing.
Quote the brand and part number !

If your Windows 7 is 32 bit, all Microsoft 32 bit operating systems 2000 and up have a 4gb virtual memory address limit, for both the ram and Windows. You can't actually use all of the 4gb of ram.

The 4gb virtual memory address limit for 32 bit operating systems.
An example of 3gb working better than 4gb in a 32 bit operating system.

If you didn't look up the ram you bought on the ram manufacturer's web site to make sure it will work in your mboard model before you bought it, in may not be compatible with using it with your mboard ! !

In the worst cases of incompatibilty your mboard WILL NOT BOOT all the way with it installed, and the mboard may not even beep !

It is easy to test for incompatible ram that has caused your mboard to fail to boot.

Make sure you have a speaker or speakers or the equivalent connected to the mboard so you can hear mboard beeps (see your mboard manual if you need to).
Remove the AC power to the case/power supply.
Remove all the ram.
Restore AC power.
Try to boot.
If nothing else is wrong, you will get no video but you will hear a pattern of beeps that indicate no ram is installed, or a ram problem.
E.g. for an Award bios or a bios based on one, that's often a beep of about a half second, silence for a half second, a beep of about a half second, silence for a half second, continuously.
........

See response 5 in this for some info about ram compatibilty, and some places where you can find out what will work in your mboard for sure:
http://www.computing.net/hardware/w...
Correction to that:
Mushkin www.mushkin.com

Once you know which module ID strings (part numbers) work in your mboard, you can get them from anywhere you like that has ram with those ID strings.

If you have brand name ram, it is usually easy to look up whether it's ID string is in a list of compatible modules found by using your mboard or brand name system model number.
If the ram is generic, that may be difficult or impossible.
.....

Some ram manufacturer's modules do not strictly adhere to the JEDEC standards that most mboards bioses use to determine ram settings.
In that case, the ram settings in the bios Setup that the bios has automatically chosen may not be correct.
Check the ram settings in your bios - the ram voltage, and the ram timing numbers - those should be the same as for the specs for the modules themselves. Often the ram voltage and timing numbers are printed on the label on the modules.

If the voltage setting or timings settings in the bios are different from the specs for the ram, change them in the bios. The timing numbers must be as close as you can get to the same, or slower timings (higher numbers = slower) - you won't notice the difference the slower settings make.

If you have a mix of different modules
- don't mix ram that different voltages arespecified for - the bios will force the ram to use the lowest voltage, if "by spd" or similar is used (default settings) - ram that a higher voltage is specified for is more likely to not work properly in that situation.
- the bios settings must be those for the slowest timing settings of all the modules, or slower (higher numbers = slower).

Ok so my ram is a ddr3 4gb 1333MHz
I was already aware of the incompatibility with windows x86
and more than 3.5 gigs of ram... the problem is not with
windows not working right, the problem is that i cant even get
far enough to load windows in the first place!
there is no beeping whatsoever...

i checked all pins and connections
i made sure that the graphics card had its power supply
plugged in.

what happens when i plug it in and turn it on is absolutly
nothing... i can hear everything turning on and running, the
fans turn on, the lights turn on, but there is no sound or
visuals on the screen.... does this mean the graphics card we
got was doa?

Please answer ALL questions, supply info asked for, in this !

"Did you unplug the computer, or otherwise switch off the AC to the computer, at ALL times when you were installing components and connecting wiring ??"

"i checked all pins and connections"
i made sure that the graphics card had its power supply
plugged in."

Good, but answer this...
"Did you follow the directions in the mboard manual ??"

"there is no beeping whatsoever..."

Are you sure the case speaker is connected so you can hear beeps ?

Did you connect BOTH the main 24 "pin" female wiring connector to the main connector, all 24 wires, and the smaller female wiring connector to a socket elsewhere on the mboard ??


"What capacity does your power supply have ?"

Is your cpu one of those ??

Try this and tell us what happens:

" Make sure you have a speaker or speakers or the equivalent connected to the mboard so you can hear mboard beeps (see your mboard manual if you need to).
Remove the AC power to the case/power supply.
Remove all the ram.
Restore AC power.

If nothing else is wrong, you will get no video but you will hear a pattern of beeps that indicate no ram is installed, or a ram problem.

"what happens when i plug it in and turn it on is absolutly

visuals on the screen...."

Lots of things can cause that.
Incompatible ram or improperty seated ram.
e.g. If the ram has heatsinks / heat shields on it, or a slot is close beside somthing, it's often pickier to get it to seat properly.
Failing power supplies often partially work, fans and hard drives may spin, leds may come on, yet you may get no video and the mboard will not boot all the way.
If you didn't do this...
"Did you unplug the computer, or otherwise switch off the AC to the computer, at ALL times when you were installing components and connecting wiring ??"
it's quite common that the power supply, amd/or the video card, and/or the video card's slot circuits, gets damaged.

The only to eliminate the possibilty of a failing or damaged PS for sure is to
- try the subject PS with a known working computer, if the PS has enough capacity to handle the other system's load
- try another known working PS with your mboard, if there's nothing else wrong, if the PS has enough capacity to handle your system's load.
(450 watts minimum with the radeon HD 5770 card installed).

" does this mean the graphics card we
got was doa? "

Extremely unlikely, but you may have damaged it yourself.
You would probably get specific error beeps from the bios if that were the case and nothing else was wrong.
E.g. if the ram is compatible and is seated properly, the video card is all the way down in it's slot, a video problem is often indicatee by three beeps, one of them longer.

If the card was made by ATI / AMD itself, they probably test every card they make. I've seen ATI videos that show the card is tested automatically right after it's made. If the card was made by another manufacturer, they may or may not test every ATI / AMD video chipset card.

So i got this fixed a while ago,I just wanted to post that it was fixed... I made a stupid error, i assumed other people understand computers... the person who i was building this for wanted to help and so i had them setup the monitor, thinking "how could he possibly mess that up" and he forgot to plugin the power supply :) durp durp, should have checked that first :)

thanks for all of the help.
