Gigabyte GA-7N400 Pro2

Yes, but please make sure you buy the PCI interface version, some of available USB 3.0 card in the market are mostly PCI-express interface. Just tell the store you will install it on the old PCI slot (white one). You also ask them if they have issue with the card that they recommending to you.

take out the processor chip and clock battery along with the ram while it is disconnected from the wall outlet and wait about 5 mins. after you put it back together, if the problem persists the processor might need to be replaced or the entire motherboard its self.

Possibly Ram, try and see if removing and replacing helps
Other causes may be voltage issues ( check the bios and see what the various rails are telling you)
eg: there should be readings for 12 volts 5 volts and 3 volts, if any are + or - by 10%, there is an issue with the voltge controller. You might want to try a replacement PSU?

After this.. bad video ( check by installing a video card)
Temperature warnings ( check in bios to see under PC health status) what the cpu and board temps are running at, if above 70 degrees...overheating issue or more likely at start up, board thinks that the CPU fan is not running fast enough or not working. If fan IS working, you have a problem with the CPU fan sensor, will need to replace mobo

There's a good chance that your battery is bad. It could also be that the CMOS jumper is on the wrong pins; which results in reseting your BIOS all the time. If it's not either of those then it could be that your CMOS chip that controls the real-time clock and other things is malfunctioning. If that's the case then you're probably better off replacing the motherboard. Getting someone to replace the chip will be hard to do and will cost you more than the motherboard is worth - most likely. Please leave feedback & a ratings vote on the info I've supplied.

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.

For starters you read your Instruction Manual or User Guide and you will find it there. If you have no manual, you will need to go to our sales department and buy one. CONSTANTIN (arzconst)
