[SOLVED] PC Won’t post

Hi all,

Playing my PC today and it randomly turned off and when I startthe PC back up the PC would power up but not post. I can’t even turn the PC off unless I turn off the power at the back of the PC.

A few months ago I did upgrade my graphics card, new PSU and motherboard. This issue did happen before and I left the PC on and it did eventually randomly post but it’s happened again today and I can’t get it to post.

I tired a CMOS clear which didn’t seem to work and try powering it up by taking parts out but still can’t seem to find the issue. I would naturally think it’s the PSU but with it new I can’t see that being the issue.
Any advice or help would be great

Problem is not power, it's quality. It's a common misconception that "more power = good" when in fact people needed better quality, not more wattage. To put it simply:

A good quality 650W = Fine, no problems, can run most systems with headroom.
A poor quality 650W = Potential stability issues, restarts, damage to other components etc and in worst cases, fire.

I'm going to assume based on that you have a Corsair CX650 - in which case it's a decent PSU, depending on how long you've also had it, as PSUs - like all components - deteriorate over time. A top quality PSU I would've used 10 years ago is not one I would use today.

All in all, with just the barebones of info described, I'd sooner be looking at PSU. I'd be checking motherboard debug LEDs if possible and have a motherboard speaker installed to see if there are any indications by the MB in the future.

This sounds crazy but it’s working now after I let it run for around 1 hour! Sorry for wasting your time.

but any reason why this happens? I don’t understand how it fixes it self? Is this a common issue I’m just so confused.

thanks

I would be asking the same question as above my friend :) Would need to know full spec first.

Usually if something "fixes itself" it tends to mean it could just happen again later on down the line -as it appears you said has already happened once - I would say there is nothing fixed, instead you have something going wrong that can pass for a period of time after it's left for a bit.

Exactly what i was thinking to!

Ryzen 5 Core 6 1600
Gigabyte AB350
GeForce GTX 1660 TI
16GB RAM Vengence
Im not sure of the PSU as I took the PC to the shop to get fixed but they assured me it was more than enough power and i know its a corsair maybe 650x?

Do you need any more thanks :)
