Hello the homepage is here:

The cpu list:

The intel cpu will not fit this mainboard it`s a AMD socket 462.

Good luck

Your GA-7N400 PRO2 motherboard does not have a built-in video graphics card. You need to install an AGP 8x graphics card into the AGP slot on the motherboard. When you removed the heat-sink & fan assembly the CPU starts to over heat & the CPU will shut down the system. That's why you heard the, european ambulance sound.
If it wouldn’t, you would fry the CPU. Make sure you add thermal grease on to the CPU before re-assembling the heat-sink & fan. Don't forget to plug the CPU fan power connector on to the board.

You need to Plug the Fan to the motherboard. I uploaded an image. http://img140.imageshack.us/i/overviewl.jpg/ Hope this helps

i think the cpu may have a problem with the board or the memeory. either its bad, damaged or incompartible with your system. try out another cpu

It sounds like your CPU might be overgeating. Check the CPU heatsink fan to see if it is spinning. Also, make sure that you clean out any dust, as this can lead to overheating also.

Hi sebaswis, am I correct that this Gigabyte GA-7VRX is a replacement MB? (I read your other posted questions). http://www.fixya.com/support/t1399506-computer_boot_when_power You mentioned you put your old system back together & it worked fine. If mother board is shorted to the system case you will see the CPU fan spin for a second. Most motherboards use a green led which represents there is stand-by power running to the board.(This is normal). I am unsure why your led is orange. (Its not mentioned in your manual & manual does not show the led?s location). Was the other GA-7VRX MB led always orange or was it also green? Suggest you disassemble the heat-sink from the CPU. You mentioned you installed a new XP 2500+ CPU. If a pin on the CPU was bent during installation of CPU into the socket or if no thermal grease was applied or too little to the top of CPU, either would give you: CPU fan spins for a second & nothing else seems to run. Look over the link provided below. It is a guide to how to install a motherboard. (You may not need this but Its worth going over all the steps). http://www.hardwaresecrets.com/article/145 As far as the power supply. If the MB's are the same (GA-7VRX) & the old system ran with 220W, the newer one should also function. Clarify these questions for me sebaswis. Mike

Gigabyte actually has a very good website. I pasted a link below to the CPU support list.

As far as what would be the best to buy I would say the closest to the top that you can afford ignoring the P4-Extreme CPUs.

you should check vrm section &cmos jumper & ram & cmos battery&bios

hi reason y it wouldn't start is because the 2 is not compatible, what u can do is get a Intel P4 not a celeronD check the socket size and make sure that it correspond with the board that u have. The board that u have uses a 478 socket size so u need to get a processor with the same socket size ok... that should do the trick

Check the speed of the fan in the BIOS and set it lower, although 58-63c is alright for a CPU (P4 is rated to go up to 70c) you might want to make sure that you have good air flow in your case to make sure the CPU doesn't overheat. Usually you can find the fan control in the Advanced section of the BIOS. You'll also want to check the specs of the fan that you have installed as that will tell you how loud it's supposed to be. You might have to get another fan with lower decibels if you want it to be quieter.
