PC will not start!

Reptile Guy · 18 Sep 2015 at 12:07

I shut down my PC on Sunday night, everything was fine. Went to turn it on the next day and nothing happened! Tried everything, test psu and plug. I've never had any problems with it before. I have no clue what's wrong with it! Thanks in advance

I'd start with:

1. Clear CMOS and try to start it again.

2. Take out GPU and try with onboard graphics.

3. Unplug PSU power cable, wait a minute then unplug SSD, HDD, DVD (if any) and try to post with just one stick of RAM (switch sticks around/use other DIMM slots if needed).

Fuse?

What are you getting on your screen?

Reptile Guy · 18 Sep 2015 at 15:29

Cleared cmos and tried without gpu, changed the fuse and nothing happens on the screen, just dead!

I have the same issue with the exact same board with my i5-3570k. I can get it on, barely. Reset CMOS, turn the psu switch off and unplug kettle lead for 5 mins, turn off at mains. My screen is black and it switches between hdmi and analogue don't know if yours does the same? Notice that your leds don't show on mouse and keyboard? When / if it's looping, on for like 10 seconds and then restarts, the above was the only way of getting it on. When it's on its on I've had it under load etc and left it on for over 24 hours no problem. Do you know if your using F18 bios or have got rapid storage tech driver installed?

Edit - I've tried a new CMOS battery, fuse and kettle lead no luck yet need to test my board cpu and psu.

are you using any extension leads for power or a UPS?

try connecting directly to the wall socket if so and see if this helps.

is the PC getting any power at all? when you turn it on does the fans or any LEDs come on to indicate the PC is getting power? try a different power cable as well for one you know is working

My guess would be a dead PSU.

FloppyPoppy · 18 Sep 2015 at 17:32

Imo this sounds like a psu has quit its job. Hopefully in its sleep lowering the chance of it taking the rest of the system to the grave with it.

+1. psu is a simple fix. Could be worse.

dromi · 18 Sep 2015 at 18:36

Like everyone says first suspect surely the PSU!

Reptile Guy · 19 Sep 2015 at 09:30

Tested psu and it works fine!

vantastic · 19 Sep 2015 at 12:11

Hmm, it must be a hardware failure somewhere. Im stumped.

Danny75 · 19 Sep 2015 at 12:23

Did you try disconnecting the drives yet?

Reptile Guy · 20 Sep 2015 at 00:15

Yeah, tried disconnecting the drivers no luck! Would a cpu failure curse this problem?

freddie64 · 20 Sep 2015 at 08:54

What case are you using?

Could be the case power button has failed somehow.

Try bridging the relevant pins on the motherboard front panel socket.

docsonic · 20 Sep 2015 at 09:47

Re-seat ram? Try with just one stick of ram?

vantastic · 20 Sep 2015 at 15:35

I think he has already tried that
