I just installed a new CPU cooler. Everything is attached again to my mobo (I think ok - haha)

When booting my PC gets into a loop and I cannot log into Windows. A clicking sound is made and than boots again.

The BIOS can be reached. I already have set everything to its default values, without success.

The CPU is recognized as well as the SSD that boots. The Windows 8.1 bootup screen is displayed and than a loop.

Afterwards the Repair mode is coming up.

What can be the issue for this reboot loop? Have I overlooked something or maybe not connected the right way?

I think it's the PSU dying or already dead... (the PSU is 5 years old and almost constantly on)

damn!

 

The sound is a clicking sound, and my computer gets in a constant reboot.

 

Question is, since I'm already thinking of getting a new PC, will I just get a new PSU or now a complete new PC, mobo/CPU and everything...?!

Don't expect a reply in here in 8 hours.

 

PSU's can often overload components, therefore creating electric whines.

 

Get a new PSU. You can use it for your next build.

I installed the new 860W Corsair PSU.

However, problem is still there.

 

What I see:

- the BIOS is displayed

- the Windows 8 bootcircle

- 2 clicks

- Windows bootcircle continues spinning

- that the reboot

 

After that a screen is displayed "Preparing Automatic Repair" which cannot repair anything....

 

Help! What might be the issue here?

It's a cold boot after a day or so not used. Overheating can still happen than?

Before replacing my CPU cooler Windows did boot normally, although the clicks were still there (that's why I initially replaced only the CPU cooler)

I'd check all your connectors in case something got knocked loose in the process (fans, usb, SATA, whatever,) reset the BIOS, and if still no go reseat the proc and HSF (possible too much pressure, possible too much goo and it got onto the components)

 

920s are twitchy beasts.  I gave up on mine.

 

(If the PSU definitely isn't the problem I'd find a way to check the SSDs too.)

have you tried putting the original cpu cooler back on to see if it boots?

 

with your new cpu cooler did it come pre-applied with thermal paste or did you apply it when you switched out the coolers?

Disconnect the power connection for the new CPU Cooler (Fan?) to the motherboard and then try boot the system.

 

If it fixes the issue its the CPU Cooler.

 

p.s Just disconnect it for testing, don't keep using the computer as the CPU will probably overheat without the cooler with prolonged use.

I had a cooling fan that was plugging into a laptop causing the light to just blink but not turn on. After unplugging the cooling fan the laptop turned on. So maybe the fan is shorting it out or something.

Have you tried booting into safe mode to rule out windows being the problem?

http://www.howtogeek.com/107511/how-to-boot-into-safe-mode-on-windows-8-the-easy-way/

 

Where are these 'Clicks' coming from? hardware inside? speakers??

 

 

Also, does your graphics card have a separate power feed and is it plugged in correctly?

 

 

Whatever you do, do NOT try and turn on the PC without a heatsink attached.

 

 

Resetting the bios can sometimes also cause more problems. i.e it might disable SATA AHCI and revert to old IDE mode which will make windows fail to load if it is expecting it to be AHCI compatible.

I would triple check the hard drive connections.

 

Both the power connection and data cable -- including the cable to the motherboard.

 

You might swap out the data cable too, in case it is bad.

True, though I'd expect people modding their comp to be aware of that and change it to the right setting, since they had to when they set up the comp in the first place.

I tried this, but the BIOS error I get is that the CPU fan must be connected. No boot at all.

 

The old fan isn't working any more, so that won't be an option.

Tomorrow I will place the CPU once again and see if it's working. In the BIOS it's recognized. I applied the paste myself.

Keep you all posted.

I think it might have something to do with AHCI and IDE and some BIOS setting.

When quickly changing AHCI the clicks were gone, but an error message popped up that My computer/Windows has ran into trouble.

 

I will dig in this further tomorrow.

 

Thanks so far for the feedback!

If you're booting to windows it's not your PSU. The motherboard checks for sufficient power before even attempting to boot. If you have insufficient power, you might just hear fans running. An improperly mounted or insufficient heat sink would cause a thermal shutdown, not a reboot loop into Windows. If the CPU was damaged you wouldn't POST or get past the BIOS. I suspect you're hitting a blue screen in regards to the disk controller and the machine is configured to reboot on stop errors, hence the loop. Can you access the Windows boot options before it loads windows? Can you get into safe mode?

I've seen this issue recently, and it turned out that one of the RAM sticks was loose.  It occurred after cleaning dust out the case, so changing the orientation knocked it loose.

 

Not sure if it's the same issue you're seeing, but it's quick and easy to check.

That's good, one of the fault conditions which will cause the system to boot cycle (or shutdown) is if the CPU Fan is not detected. Your BIOS gives you a warning message when this happens so its safe to say the fan is being recognized and doesn't have an internal short or open cct which could be causing the failures. Make sure no cables are getting stuck in the fan during operation and that it spins freely and you can rule out the cpu fan.

Does it still try to do a boot cycle or is it staying in Windows now with an error message?
