Last night while I was watching NS LCS TiP vs TL, my PC just straight up shut off for no reason. I couldn't get it to turn on so I jumped onto the laptop to finish the series and went to bed. Today I decided to tackle the PC problems. When I give it power the CPU fan comes on, my LEDs come on, but my case fans, hard drive and graphics card don't boot up. What causes this and how do I fix it.

Does it make any beeps?

Do the fans go to max speed?

Have you checked if the RAM detached?

Have you checked all cables to make sure none are loose?

There can be a million problems. Dont know that much but try removing all RAM sticks and inserting only one at a time. See if it boots up.

 

Turn off the power and then turn it on on the power supply  :D

Is there a slight burny smell in your system?

If so, remove your PSU immediately.

 

Alternatively, check your components for any damage or if anything's loose.

Definitely sounds like the PSU, I basically had the exact same problems a few weeks back. Also on a Corsair PSU. Replacing it did the job.

No Beeps, not sure about the fans max speed, ram is in all the cables are tight.

You would hear the fans if they were maxed out...

Oh my been so busy I forgot to update this thread. Well he only had a spare psu and swapping it out didn't fix the issue. I've been super busy this week getting ready for uni and working so I haven't had time to really look into a solution thankfully my laptop can get me through for now but alas my gaming will suffer as long as Bombour remains in a coma.

PSU failure for sure unplug your psu before your intire system dies...

Or if you just build the system check the cables if everything is plugged in like the case fans...

If you bought a pre built , and add upgrades like gpu or extra drives , possibly over run on the power supply.
