Hello guys,
So when i boot up my computer it does 1 long and 2 short beeps. It boots normal after the jumper thing but when i shutdown it, same thing happens.
Also when it boots it says cant detect TPM device.
No i dont have a graphics card.
Pc specs:
Acer veritron s480g
Core2duo e7600 3.06ghz
4gigs ddr3 ram
2x 160gb hdd
300w psu
I will link a screenshot of the mobo.
Thanks.

I would try replacing the battery like Captain recommended. 1 Long, 2 short is a "damaged bios" beep code and that mobo is 7 years old. If that's a stock battery it could easily be dead or close to it by now and those 3 volt batteries are inexpensive and nothing to change. That or try re-flashing or installing the latest bios version.

You can download the latest bios version from the link attached below. You would then need to put that update on a thumb drive or another acceptable storage device it can load from. That mobo is a little bit older so the only way you will probably be able to update the bios is from the bios menu. So when you first turn the computer on, continuously tap the delete key and it should enter the bios menu. From there you should have a menu to update your bios from your storage device.

Guys how do you want me to update the bios if i cant even set the first boot device... I mean when i clear cmos i can boot and get to the bios, but when i save the settings and exit pc needs to boot again and the same beep code sounds over and over...
