So my pc has been giving me boot loop pre-bios screen for about 2 years now and every time it had started (sometimes after 5 min other times after 1 hour) it worked absolutely fine with long gaming sessions and synthetic benchmarks and no issues on heat/lockups/crashes or bsods. Upon thorough inspection through software checks and breadboarding the entire system to check for shorts or other hardware failures, i continued to use it until yesterday when the pc remained in a boot loop for 10 hours. So basically no post on screen just starting some fans and then going off in a loop of start-stop like it had always done.

I narrowed it down to mobo/cpu/psu problem but since it always started and gave no other problems i could never be sure.

Now, im thinking of investing into a second z97 mobo and getting a new psu and even a case to see if i can get it going again but since i have no idea whats cause all this, i just dont feel like spending a good part of £150+ on a 5 year old system only to later find out that problem was with my 4790k cpu or hard drive or ram.

In short, do you think its wise to buy a few parts and try to make it work or just wait for a bit and then abandon ship and build a new system after nvidia's next gpu and intels/amds next gen cpus come around?

Im really torn between these options since my system is still very capable and all i would have done was to get another 8gb of ram and a new gpu.

Your thoughts/suggestions welcomed.

Rest of specs:

8gb ddr 2133mhz avexir venom
Ssd boot and other mech drives for storage
4790k at stock speeds
7970ghz stock gpu
Corsair 750w psu
 
Yup. Bios is up to date to latest f8 for the mobo which is z97 gigabyte ud3h bk cf revision 1.0 and went through ram stick test 1 by one and also had them replaced once.
 
Just to add on to that. All hardware was at stock since the day i started to get these boot loops 2 years ago.

I even underclocked cpu and disabled HT.
 
I had a similar issue once and it was the psu. Power was fluctuating which gave you sporadic boots. Might be a good starting point if you have spare you can try.

Thanks.

The thing is i do not have access to any other spare components hence the reason for this post. I wanted to know whether its actually worth getting other parts at this stage to narrow down the problem. I can probably get a new psu which I can use in the next build but what if its not the issue and the problem is elsewhere?

Perhaps borrow one if you can from a friend. If your really desperate you can take just the mobo cpu and memory to a shop to test if it's not too expensive. At least then it will help rule one of the 3 possibilities as you have to start somewhere. Else it's a guessing game.
 
Thanks again.

I unfortunately have no one to ask for spare components and the one time i took the pc to a pc repair shop and after spending some cash all they did was to say that there is something wrong with the cpu. I chose to not believe that since after that the pc did turn on after boot loop cycles and ran smoothly under load.

I guess one way or another, I will have to start somewhere, however, i was hoping someone can point me in a direction i have not thought of yet considering i have tried pretty much all obvious steps in troubleshooting.

It's handy to have a spare psu, can you perhaps get a low budget unbranded generic one just for testing bare minimum components. No idea how much but it shouldn't be too expensive. Have you tried ocuk mm?

I will actually get a low key psu, any specific wattage that i should aim for?

As cheap as possible, should not need that much to test mobo cpu and memory. Whatever minimum requirement. Any psu calculator will do. This might help http://powersupplycalculator.net/

One thing can I please reiterate. Not saying it's definitely the psu so be prepared to waste a little cash but look at it this way. It will help save you time and pain which will also be handy in the future so imo it's worth it and something I would personally start with. Good Luck mate.

Thank you very much for your suggestion!

I really hope to solve this problem that has nagged me over for far too long.
 
Forgot to say if it does end up to be your psu. Remember Corsair have great warranty cover. I bought a new one and had the old one as fallback which helped when my problem occurred. So depending on the model and how old it is, it may have 3 - 10 years cover to get a new one :)
