Hi! Tried turning my PC on today but wouldnt power on. Lights turn on and fans start spinning but nothing happens.

 

My motherboard is flashing CPU and DRAM.

 

I have tried:

Reseating both sticks of RAM

Using only one stick of RAM 

Reseating the GPU

Removing the GPU

Removing and replacing the CMOS battery

 

Could it be a motherboard/cpu problem? I hope not because I literally have no money and will not have money for the next few months.

 

CPU: i7 10700k

GPU: GTX 1070

RAM: HyperX Fury 16x2

MOBO: MSI MPG Z490

Misery!

 

Could be any or all of the above.

 

Do you have another system to test / swap out components?

 

Ram, PSU and GPU are usually the easiest.

 

Have you tried doing a bench build? It wouldn't be the first time a wayward screw stuck behind the mobo in the case has caused me a headache.

 

If the the Mobo has a the facility to flash the BIOS without the CPU, that might narrow the possibilities further. I would imagine if a successful BIOS update without the CPU installed would mean the Mobo might be ok.

Unfortunately I don't have spare parts.

 

I'll try doing a bench build later, once I calm down LOL.

 

Thank you for the reply!

 Hi! Just wanted to update. I fixed it by replacing the CMOS battery. Not sure why that fixed it since I already removed and replaced the battery.

Great work. TBH, I wouldn't have spotted that. Probably replaced the mobo and wasted £150. Well done.
