No boot, fans spin except case fans

[Phllips]

My pc black screened 3 times and now it isnt turning back on, when i turn it on the lights for my case fans turn on but they dont spin unless i manually get them started. All other fans spin but slowly. 

Before the 3rd black screen I did some temperature tests and some benchmarks, gpu was maxing at 85 during the valley benchmark and cpu wasnt going past 70 on prime95. So I assume its a motherboard or PSU issue. Is there anyway to test which ones broken if not both without finding other parts to test with

I had this exact same issue, turned out to the a faulty PSU failing under load. So most likely that.

Really your best bet would be to sit down with your PSU and PSU manual with a voltometer and just start testing each lead and making sure the right voltage is coming through, after that your next best bet if the PSU tests fine would be to do a CMOS reset in case there's something that got modified in the BIOS

I had an issue with my PSU some 6 months ago when it turned out the fan wasn't always starting, fixed it by slapping a spare case fan  on top of it so I wouldn't be surprised if that were it.

Yeah I'd definitely get to trying a different one first.

I don't have a voltmeter nor do I really mind buying a new PSU, I just wondered if it was likely that the motherboard was fried as well and I should order all the new shit together

Might see if I can  find one somewhere otherwise I'll just buy a new one, my only concern is that the PSU might have fried some other things

If your mobo still posts and boots into windows, there "shouldn't" be an issue with it

At least in the experience I had, nothing else fried. Don't know if that's normal or if I got lucky, though.

Thanks for your help, in truth an upgrade isn't the end of the world anyway but I was hoping to wait till the next gen of cpu's were out

No problem, let me know how it goes
