Hey Guys,

Hoping someone a little more tech savvy can help me. Been having this issue for the past few weeks where my pc freezes whilst playing a game which then requires me to force a shutdown by holding the power button. After doing this it refuses to turn back on for a while. It will also take a while to start in the mornings with me having to press the power button numerous times for it to start. When it's running, it works perfectly fine, I haven't had any errors or beeps while trying to start up, no blue screen or anything before the shut downs. I thought it was an issue with the PSU but after swapping it out, I'm still having issues.

Run a number of temperature tests and it doesn't look like temp is an issue.
Does that mean it has to be the motherboard or could it be another component or any other suggestions would be helpful. Physically inspected the motherboard and no bulging or damaged capacitors from what i can see.
