[SOLVED] Weird Issue : PC won't turn on

[abhirajsr]

I really appreciate your help because I'm really frustrated.


My PC didn't turn on at my house one day. No light's or Fans. I tried changing PSU, Cables, Plugs, Connectors etc . I took it to the repair shop and it worked perfectly everytime they start it ! .

I came back to my house and started it and it worked as normal! After 2 days another morning it doesn't start at all again ! Checked all plug pins in my house, checked at neighbor's house and still not turning on.

Went to the repair shop and it works fine ! They tested motherboard and psu said it was working fine.

If this is my area's electricity issue, how does it work when after coming back from shop?? I tried 2 different shops and worked on both.


Please Help. It's really tiring me.

check the back of the power supply sometimes they have a switch to switch between 120v and 240 v. check that out.

if your house has dirty power, meaning the voltages fluctuate harshly like overvolting or undervolting, then you might need a pure sine wave battery backup or inverter. because the power supply could be thinking its overvolting or something. so the power supply is protecting the pc. there was an episode of linus tech tips where they were testing out some computers and one didnt turn on because the room they were in had old wiring. i think it was one of the scrapyard wars.

here is a video that explains the whole sine wave things

My psu doesn't have a switch.

Also after I come from shop, it works for 2 days. If it's my voltage issue then this shouldn't happen right.

Thanks for replying

If you have 2 rams try using one at a time

I do have two rams. I tried using one and tried a ram from another computer. No difference. It just wont boot.

even if it's a ram issue. how would it work at the shop with same ram. not at my home

Sometimes cleaning the ram pins works
