[URGENT] PC would not boot up after dusting it.

[VladyVlady]

So i got this new custom build PC about 6 months ago and i had no problem with it till now.This morning i decided to clean/dust it as it was pretty messy.I took the side panel off and used a vacuum to clean it.(I have done it on other PCs before).When i plugged everything back and i pressed the power button nothing happen. I checked that all cables inside the PC are plugged in properly and it seems like they were.I looked up at other threads on this website and i could not find an answer.My dad got home and i told hem about it, so he got a voltage pencil and checked the power supply cable, to find out that there is electricity on all 3 holes (I am pretty sure there should be only on 1 ). I got another power cable to try it and it is still not working.

I was thinking to get all the parts out clean them and build the PC again outside the case and see if it works . Do you think that is a good idea ?
Please help .

Try testing firstly the power supply: https://www.youtube.com/watch?v=5FWXgQSokF4
See if a connected fan does spin.

I have just done the paper clip test and the PSU fan starts spinning so i guess it works

Then leave only CPU and CPU fan installed, 24 and 8 pin power cables. Remove all othercomponents/cables. Start the board by shortly touching with a screwdriver the 2 pins on the motherboard where the case power button gets connected.

Be aware that you should NEVER use a vacuum cleaner to clean electronic circuits. The rush of air over the nozzle builds up a huge static charge that can zap chips.

Hopefully that is not the case and you have just overlooked a cable, but I wouldn't clean your computer like that in future.

So do i just connect the cpu and the cpu fan ? do i need to connect a monitor too or what is it supposed to do ?

i am pretty sure i checked all cables because i had to take out the PSU to do the test . I took a look at the power button just in case but it does not seem to be the problem.

I think there might be a problem with the motherboard .

Is there any chance for my CPU to be the problem?

Yes. No need to connect the monitor, as you'd check only if the fan does spin without stopping.

I have done the test that you told me (CPU and CPU fan only ) when i connected the 2 pins with a screw driver nothing happend

Then it might be a motherboard issue. One more test. If removing the 8 pin power cable and connecting a case fan to the motherboard, does the fan spin when starting the board?

I have no idea what to say... i connect the 2 pins and the fans/lights work for like 0.3 sec and then stop

Then I'd say that 99% it's a motherboard issue (if no other cables/components connected that could short the board). If under warranty, try RMA-ing it. Hopefully the other components are OK.

I want to say Thank-you so much for all the very useful help that you offered me and that you just made my day better by knowing what the problem is

Thank you so much <3 <3 <3

I got the board and it works now !

I was going to ask about the temp of my processor .It is about 50'c on idle ,60'c on games like csgo and lol and about 75'c on games like gta5. Is that bad????

also here is a picture of my pc,http://imgur.com/XZZXdQy is it good?/any tips on improving?

Using the stock CPU cooler?

yeah , as you can see in the picture xD

Its an I5 4690K btw

Then I suggest replacing it with an aftermarket one. Clean the old thermal paste and apply new one.

is it going to be ok for like the next month or so? as i don't really have that much money right now

 

[alexoiu]

50 when idle is a bit too high, even if stock cooler used. Are you OC-ing? Have you cleaned and reapplied new paste before installing the cooler?

i have cleaned it and put thermal paste today and i am not OC-ing

Right now when i am watching some streams is at 45

Try not straining the pc too much until replacing the cooler and monitor the temperatures. It would be good to not go over 60-65.
