Cant Turn on pc

[Chiken1232]

hello some days ago when i turned off the switch on the psu it came a wired sound i dont know how to explain it well when i tryed to start it again it didnt start so i went to a local store so they fixed it they got it to start fine after taking out and put back some cables well i dont know this stuff so good but then i went home pc started i did some benchmarks to stress the system as they told me to it worked fine then i turn off pc again and now it wont start help me ;( no bios or anything nothing shows that it got power but at the place they tested the powersupply and sayd that it worked fine

Is the socket switched on? Is the switch in the on possition? Is it plugged in??

Before you do that open up you computer and check if all the cables are plugged in properly! Then re-connect it to the mains

i dont know much about pc parts so i should not touch and do things so much

[Chiken1232]

and everything should be in because it happend when i turned off then tryed to start 1 min later

if i cant fix it i got to pay like 55 euro

i looked in it and seems like all cables are on place

Had the same issue before. Sounds very similar to a faulty PSU. Fails under load, whether that's when you get to benchmark or even as little as powering the components. It sounds like a faulty PSU. I wouldn't go straight ahead and buy a new one (unless you'd rather save this whole trouble) until you've checked with another PSU, a friend's maybe?
