Help needed with boot code 3A please

I have just replaced my graphics card to try and solve a different OS problem, however after re-assembly instead of full boot-up I received a code 3A which I don't know what it simbolizes and where I need to look for the actual problem to fix it.

Can anyone help to get me through the problem please ?

I am getting a bit on the old side now and my memory is letting me down so I am finding that getting answers much harder than a couple of years ago.

Thanks very much for any help from some of you very clued-ed up guys and girls :)

Hope to hear from you all soon

Is this a BIOS beep code? Did you check your mobo manual on its Support Downloads webpage? Gigabyte Technology Co., Ltd. F2A85X-UP4 3a beep code - Google Search

The closest I see there on Page 90 Beep codes is 1a-2a which are Reserved.

If the only change you did was replacing the GPU then I would check it's correctly seated and pull the CMOS battery to Clear CMOS - 3 Ways to Clear the CMOS - Reset BIOS. Make sure you pull the AC plug and hold power button to drain residual power first.

Gooday,
Thanks for the quick reply, however I am borrowing someone elses PC and I can't get it back till tomorrow
the person is taking it as soon as back almost as soon as I hit the "enter key" and my system is down & out at the moment.
As soon as I get it (or another) I will shoot a reply back.
I'ts 4:25 am here at the moment.

Thank you
