Computer won't turn on

[Khamslp]

Help!

 

After cleaning my computer case and some of its components last Saturday, my computer won't turn on or show signs that it's receiving any electricity whatsoever.

 

My computer components were a 2600x, b450 tomahawk, and the PSU is a tx650 that I bought like 8 years ago.

 

Checcking all through the internet, I placed an order for a different motherboard and psu just to see whether this would solve the issue, pinpoint the problem and return whatever one of the two wasn't the issue.

 

Turns out changing both of them didn't make any diference and the problem remains the same :( I've sent the tomahawk for RMA in hopes tht it would be the issue but it doesn't seem to be (haven't heard back from the shop yet, hardware is on the way to them).

The new hardware I purchased are a RM850 from corsair and b450 gaming pro carbon but alas computer continues not to work.

 

What else could it be????? I mean, I understand that ram, cpu or vga could be giving problems as well but the computer would still turn on, right??''

 

Sorry for the mess that this post is but am quite desperate to find a solution :(

 

Thanks in advance!!

did you use compressed air? if you used something other than that (maybe with static electricity) it could of killed your motherboard
sanity check for me, is the PSU switch on or off? (the Line is on, the circle is off)

did you make sure that your front panel connections were redone correctly?

The problem with compressed air from an air compressor is that air contains moisture and the tank can hold that moisture, hence why they have desiccants and inline filters to try and remove the water from entering tools. Also, if the air compressor is oiled and on the old side, it can leak oil into the tank that which gets blown through your air lines and onto your components. 

 

Have you tried shorting the pins on the motherboard connector on the PSU to see if it turns on?

Did in fact use a "brush" so it could had very well killed something and I'd own up to that but after changing motherboards and PSU, the fact remains the same, Motherboard won't show as tho it's receiving any signal, no light no nothing, no fans starting up or anything.

Yep, led + - l on the top left, power switch next to them. HDD LED right below leds and Reset sw. below power sw.

 

Thing is, even if that were the case, wouldn't the motherboard still show as tho it's receiving signal???

Did short the pins on both the old PSU and the one I just received today, both activate the fan when doing so.

 

Here's a picture of everything plugged in (albeit crappily, it's just for showing in here just now) https://imgur.com/a/TYi3lfQ 

 

I think I need a miracle. I could buy new ram sticks and cpu to really just try EVERYTHING but of course rather avoid it

yeah it would

Yeah, don't use a brush on electronics....1.  static.  2.  physical damage.

 

Ye old computer gods are not happy methinks

and I completely understand that, I was gentle but I understand static is a thing, even if it was an external cleanup.

 

The thing is, the situtaion persists with brand new hardware that was not present during the cleaning. (Motherboard and psu, cpu vga and ram are the same)

Have you tried just testing the system on top of the ESD bag the motherboard came in on top of the motherboard box with the CPU, CPU cooler, GPU, HDD, and PSU plugged in and tried shorting the pins to turn it on, unless it has a power button built into the motherboard?

To be honest, I've tried evverything I can think of.. including that, I did on the ESD bag and on the cardboard box. I've placed one ram module, two ram modules, swappng from one slot to the other.

 

I've cleaned the CPU and mounted the stock cooler (I'm waiting on a dark rock pro 4 tho at this point am not so happy to have purchased it) again but nothing seems to work.

 

I've tried with everything plugged in and with just the cpu and 24pin plugged in.

 

nothing ever works and it's driving me nuts! I got half a mind to get ram sticks and a cpu to definitely be able to try out evverything but I don't wanna end up with lots of stuff tht can' be refunde (Amazon might be alerted if I refund too many things.. )

Have you tried a new power cable? Cables can go bad.

Yep, got a new psu that got here today as mentioned and swapped between this and the old psu cable, as well as the monitors... doesn't make any difference

Is the computer plugged into the same outlet as the monitors? 

[NZKshatriya]

is the circuit that the system is plugged into tripped at the breaker?
