PC unable to boot / boot loop

CuteTurtle · 27 Jul 2014 at 20:42

Hello today randomly my pc just shut down and started again but won't get far. Every component is new except my PSU. I think it's the PSU problem but I want confirmation. Pc doesn't get as far as bios sometimes, but if I turn off my PSU and wait a little then turn it back on it can go as far as to Windows homepage but then shuts off and starts looping again

If it is the PSU problem can you suggest me a new PSU? I have i5, gtx 760, gigabyte h87 hd3

Is the spec in your sig?

CuteTurtle · 27 Jul 2014 at 20:54

No, just the PSU. I have what I mentioned above plus 8gb ram

RJC · 27 Jul 2014 at 20:59

Couple of things you could try is go to minimum components - just cpu, 1 stick of memory and use internal graphics.

Also check the temps in the BIOS and possibly try a CMOS reset.

CuteTurtle · 27 Jul 2014 at 22:11

Well I kept the PSU off and I got to bios, temps looked normal. How do I use on board gfx?

Remove the onboard gpu and plug the monitor into the motherboards ports.

CuteTurtle · 27 Jul 2014 at 22:59

I'm checking now but I'm getting no output to my monitor because probably hdmi cable doesn't support on board. I'll see if it still turns off and keeps restarting, edit: it does, I also removed 1 stick of ram but it still keeps restarting

I reset cmos and bios told me that on boot but computer still keeps shutting on and off

So it's not motherboard fault because it works, not cpu fault because I've gotten to Windows before and it works, not gfx fault because I removed it and still same problem, not sure about ram but I removed 1 stick and same problem, PSU is the only thing left?

ocz psu's are crap anyway tbh esp if its old

id test with another brand if you can

CuteTurtle · 27 Jul 2014 at 23:47

I can't, I don't have any. Should I buy a new one or is the problem still not clear where? If another, what type and how much?

wazza300 · 27 Jul 2014 at 23:50

what model ram?

and what cpu? devils canyon?

try and see if you can get to bios and see if you have f8 bios version on there

this looks decent psu

Kingston HyperX. I5 3570k (I think? The latest i5). What's Devils canyon?

I will look at bios tomorrow.

wazza300 · 28 Jul 2014 at 00:20

the 3570k is ivybridge

latest i5 for that board would be either the 4670k or the newer devils canyon cpu the 4690k

if 4690k im not sure but you might need newer bios to support it better (could be cause of the loops?)

but don't rule out psu either

theres also the non k haswell chips which should be ok

CuteTurtle · 28 Jul 2014 at 00:22

It's Ivybridge, 3570k not the newer one

wazza300 · 28 Jul 2014 at 00:30

you must have different mb then?

gigabyte h87 hd3 is socket 1150,your 3570k is 1155 socket?

if your seeing the bios its working so not important just confused,could be power supply only way to be sure is to try another

CuteTurtle · 28 Jul 2014 at 00:41

My mistake I meant

"Gigabyte H87-HD3 Motherboard (Socket 1150, H87 Express, DDR3, S-ATA 600, ATX, Haswell, Supports 4thGeneration IntelCore Processors, GIGABYTE UEFI Dual BIOS)"

"Intel Core i5 4670K Quad Core Retail CPU (Socket 1150, 3.40GHz, 6MB, Haswell, 84W, Intel Graphics, BX80646I74770, 4th Generation Intel Core, Turbo Boost Technology 2.0)"

"HyperX Genesis 8 GB 1600 MHz DDR3 CL9 DIMM Memory Kit (2 x 4 GB) - XMP Ready"

I'm not sure what triggered this though, it was working fine for like 3 months and now out of nowhere it shut down and kept restarting and looping

wazza300 · 28 Jul 2014 at 01:01

can only leave psu I would have thought

CuteTurtle · 28 Jul 2014 at 01:23

So I should go with SuperFlower Golden Green HX 650W "80 Plus Gold" Power Supply - Black?

wazza300 · 28 Jul 2014 at 01:26

its upto you

it is a good psu and should work fine
