Build doesn't start. Motherboard outdated. What to buy?

HigginsHEre · Jun 21, 2017

Hi I built a computer for my dad with a few old but presumably good parts. However, after not starting, a repair shop told me something like the motherboard cannot handle the newer power supply. Ideally I would like to be able to keep as many current parts as possible. What should I buy? What's the best value option? Low budget, just looking for parts to get the computer in working order. Bells and whistles unnecessary. Thank you!

i5-3570k
ASRock Z75 LGA1155
Corsair 500W

The repair shop is clueless.

There is a whole different reason as to why it is not starting up.

Seems you're right. So far I've determined that one of my sticks of ram is dead. Thank you.

OK!

They just didn't want to spend any time diagnosing, and wanted to sell you something new.
