PC reacts to near by objects with electromagnetic induction

Yeah lol, just like the title says, let's say I come by the PC wearing around a blanket, the PC starts playing the USB device disconnect sound. And if I start shaking the blanket over it (~10cm away), it plays it until the blanket is out of all electrical charges.

So what the hell, how do I fix this or is this normal?

What's the power supply? Sounds like a poor ground or something.

midts · Mar 23, 2014

What you mean ground? PSU is INTER-TECH Booster SPS-520 AC 115/230V, 50/60Hz, DC 2.2/5 12V, 520W, Retail, Passive PFC, 1x80.

Also maybe offtopic, but i.e. when fridge turns on for freezing, or you just turn on or off light switch, the monitor blinks for a millisecond, the speakers glitch for millisecond and the keyboard turns on to a laptop version keyboard (it starts to think that it doesn't have a numpad, so half of the letters starts typing numbers).

Ground is the earth wire. It should prevent the chassis becoming live if there's a fault in the PSU, and should help with discharging static.

I'd strongly recommend a new PSU - those are signs of a very poor quality power supply.

Get something decent from the second link in my sig, and your problems should disappear completely.

That is a bit strange almost like the power going to your system is not very clean. I'd say the power in your house likely has issues. That shouldn't be happening.

Someone Somewhere · Mar 23, 2014

A heavy load starting/stopping can produce fluctuations, but the PSU should be filtering them out. Cheap PSUs don't.

New PSU would solve both problems? What power PSU do I need for i3, 8GB RAM, GTX650? I use it for watching and sometimes encoding blu-rays.

Also you're probably right, the PSU I got, new costs only 25USD at my local place, so it gotta be it.

Also if you're expert can you recommend PSU from this list, this is where I buy PC stuff http://www.skytech.lt/kompiuteriu-komponentai-maitinimo-blokai-c-86_85_300.html

About 300W would be fine for that. The second link in my sig has a list of good brands/models.

It should fix both, but I can't be certain. Cheap PSUs are a really bad sign, though.

midts · Mar 23, 2014

But how's 300W better than 520W?

Someone Somewhere · Mar 23, 2014

Because a) that 520W PSU won't be able to output 520W (marketing and lies), and b) quality matters more than quantity.

Well you can find lots of videos/reviews of exploding cheap PSU's that couldn't handle anywhere near their rated wattage. The reviewer tried to test certain modest power usage and they would go boom. And at this I mean using somewhere around 300W on a PSU rated at 600W.

Well I guess I'll need one of those Corsairs or Enermax, can't find any better in my store from your Tier 2 list.

Someone Somewhere · Mar 23, 2014

Google 'Jonnyguru Death of a gutless wonder' for classic examples

Does the store have a website?

midts · Mar 23, 2014

Hey people please stop talking about explosions. I did post link already, don't want spamming.

Someone Somewhere · Mar 23, 2014

Only two posts. That's not spamming.

You did ask for how it was better, though.

If you post a link to where you're buying it from, I can pick out a good one.

midts · Mar 23, 2014

But I did post. It's still there. Didn't know it's that hard to scroll up and look for it 🙂 http://www.skytech.lt/kompiuteriu-komponentai-maitinimo-blokai-c-86_85_300.html

Someone Somewhere · Mar 23, 2014

Oh, sorry. Didn't spot the edit.

Someone Somewhere · Mar 23, 2014

OK. I'd pick up a Corsair VS350. They've not been added to the list yet, but they're reasonably decent.
