I just bought my new mobo which is a Chinese brand. So when I installed to to the case it wouldn't boot at all so i tried to find the problem and hey it was my PSU , i tried to change the PSU and yay it worked I had another 4gb ram stick that I need to use since I have windows 10 so i shut down my PC and installed the 4GB stick when I tried to boot it up i got a beep codes say it is memory problem(4 beeps) I took it to a local repair shop he said I might have damaged the motherboard when I was installing it and I remember when I tried to boot I up the second time I use a screw driver and had a little contact between the power SW and the reset SW . so what could be the problem ?
The Brand (first tech) haven't a website even nor a registered trademark and it does look like this :
