Boot loop problem/issue

I've got like £130 credit at x, so failing that I was debating just grabbing a cheapo mobo and cpu
You could just about get a H610 motherboard and a 12100F for that (includes cooler in the box), but it would need ddr4 or ddr5 (depending on the board that you buy).
 
try unplugging the hard drive/ssd and see if it will boot into bios from there with the card you tried in your main pc which works, this eliminates any MBR/boot files from causing it to boot loop
if you can get into the bios from there all you need is a new drive and to install an OS
:)
I'll give that a last try!

SHANGZHAOYUAN B85m Pro Motherboard LGA 1150​

Found this for like £69, so was debating just throwing the stuff across so it can boot up and do its thing until I want to actually replace out that full PC for a new one tbh, arrives Friday so we see how that does with all the existing parts!

so Finally got round to installing that new motherboard all worked fine when I bench tested it, put it all back together, stopped working, onjly difference being when I benched I didn't have the CPU cooler on it at all (only remember as I burnt my finger on the back of the CPU head lol) so my thought is its the CPU cooler thats failed causing the CPU to mass overheat on startup? which is odd but I guess potentially the actual issue

Very unlikely, not a lot could cause a cpu cooler to break, and even if it did, then it's not going to cause boot looping, the closest to that would be the motherboard not turning on because it detects no cooler fan plugged into the cpu header, if that setting is on in the bios ofc, so I quess, maybe a fan that is failing and stuttering on and off might cause boot looping if that setting is on
if it worked when you bech tested it, then there are other, more likely causes for a bootloop, like there being a rogue extra standoff causing a short on the board, but again that is unlikely because of it not being a new build, did you bread board the old motherboard and components?
You've checked all the leads are plugged in nice and tight right, as it sounds like the pc might have been moved around quite a lot before you bringing it back out to use it again, yeah, that's far more likely.
The side of the case that is behind the motherboard never got a knock bending the face of it where the standoffs go in ?

you made sure that the old standoffs in the original case perfectly line up with the new motherboard?

the Last ditch attempt is getting a new PSU, and breadboarding that with the new, and old motherboard, don't go leaving CPU coolers off though, that's just lazy, and bad practice, don't want a definately broken cpu on your hands, do you? tut-tut! Don't break what you already have that is probably working fine, that's just silly, might as well just put it all in the bin if you are going to do things like that

If you have an AIO then they have some passive cooling that can usually prevent overheating when they're mostly idle, so I wouldn't expect a major failure as a result.

An air cooler can be over/under tightened or unevenly tightened which can cause boot problems, though it is not super common.
 
honestly im lost lads, I'll be real, so the new motherboard like I mention had it all apart, had it on came back to it being off again in its usual bootloop pattern so I was like urgh maybe not the MB, so I like I say undid everything put the old mobo back in breadboarded it, continous bootloops, back to being baffled as now both were doing it, re-wired the new motherboard, all the exact same components, removed the CPU cooler, started up and worked fine now im just like bruh wtf is going on, so at this point im lost hah this old PC was only needed for some mini little side pieces of work and its becoming a real frigging headache lol, do I just buy it a new air cooler and assume that maybe it was the CPU getting too hot, because the AIO cooler on it just aint working it is a 2015 PC, so I mean it aint out of the question it could be goosed!

at this point if that cheap mobo above + an AIO cooler rectifies the issue then im like **** it go with that yano :confused:

So you're saying that once you install everything outside of the case, it works.

If you install it inside the case, with your AIO CPU cooler, you get boot loops? Which happens identically with both motherboards?

Are there any things that you install when in the case that you don't outside? E.g. internal USB headers and the like? Sometimes those can cause a short.

In regards to the CPU cooler: to rule out mounting being an issue, can you get hold of some cheap top-down air cooler, even an old/used stock cooler, for testing purposes?

Apologies no so the new one (MB) worked outside and inside the case prior to cpu cooler being attached (worked at first with cooler on bit then started same boot loop pattern) old mobo footloose regardless where it's sat and whether CPU off or on, I was debating since I'd already bought the new mobo I just go ahead get a half decent air cooler to slap on it and try?

It sounds like a plan, do you not have any old stock coolers lying around (in an old cpu box) that you could use?
 
Yup it's being screwed down too hard I imagine and bending the board causing a bad connection, either that or the coiler itself is shorting something.

There is literally no other possible explanation.
