This might be a stupid question bud do I have to have the ssd installed in the machine after programming the bios chips

nope , if you can get to post the board your good to go , you might try finding a good working ram or try to dissemble the board try using external monitor and only board , ram and if you jumper the power button you can do it also to just isolate the probability of some hardware issue

Great idea I'll try connecting it to the tv with a hdmi later and see if that works

Your CPU is skylake. It can`t be the 1st bios as that has ME 10 firmware, or the last one as thats too big. 0804E and F have ME 11 firmware, so its one of those. The 5:3 error can sometimes be caused by loose ram slot pins,so check all those carefully.

No worries its onboard ram ill double check the solder joints on the ram later thanks again for all your advice ill go and put another donation in just now and ill keep you updated on how i get on with connecting to hdmi to tv and checking solder joints

Now i checked everything and tried all the files again olso checked with hdmi to tv i have another board doing the exact same thing 5x3 cap lock flashes the other board was working great until i accidentally knocked 2 caps off with the crocodile clip taking a coppy of the bios file i replaced the caps but same thing i managed to get a replacement board so these two boards are for experimenting i was looking to get one up and running for a spare but im running out of ideas

Im thinking its a hardware issue probably the onboard ram went bad with the wrong bios been flashed if thats possible

Does anyone know the number of the bios chip of the hp spectre x360 13-4129na as the numbers on my chip are gone I've ordered a different programmer and I'm looking to program a new chip I'm thinking the original chip could be faulty

There are 3 different bios chips listed in the motherboard schematic

EN25QH64-104HIP 1C7017
W25Q64FVSSIQ EF4017
GD25B64BSIGR C84017

And in the 0804E/F bios these chips are in the VSCC table

Flash chips in VSCC table:
EF4017 (Winbond W25Q64)
1C7017 (EON EN25QH64)
C84017 (GigaDevice GD25x64)
