Arduino nano unable to establish connection with laptop

[arsh217]

New to Arduino, can't get it to connect, help very much appreciated

Hello, new to Arduino and getting very frustrated. At the point happy to pay someone to assist! I have an Arduino nano (Duinotech) ATMega328p. It's connected via USB and lights up also the 'tx' light. However I get errors trying to upload the sketch. Error: avrdude: stk500_getsync() attempt X of 10: not in sync: resp= I've found a page for this and followed it, but didn't help. Tried ATMega328 Old Bootloader, and a few other things, made no difference. Looked up Device Manager and it doesn't…

I think it's the same chip as in this case but it's unmarked
