Pc only posting 1 out of 10 attempts, method of diagnosis?

Unfortunately, I'm at an all time low of spare parts.

I've got someone's Advent pc here to fix, it rarely posts, when it does the cpu fan ramps up to full speed (no fan speed options in bios).

Ram is fine, just using the one stick for now. Cpu is a q8200.

I need to order spare parts anyway. But out of interest, what would your next test be? I'm hoping it's a PSU issue, but deep down I fear it needs a new motherboard.

Anyone else had a Psu that would only boot some times?

Excuse the formatting, posting on my phone.

No error beep codes to help you?

No beep codes. Take out of case to test is on the agenda too.

It stays on forever when it fails to post

Back in the day those symptoms would point to failing capacitors.
