|"since i have not loaded the bios in |
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.

Ultra Ga-p55a-ud3 - no such thing on the Gigabyte web sites.
" i5-750 cpu "
Your specific i5-750 cpu must be on this list
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.
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.
See Response 6:
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:
Correction to that:
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).
