[SOLVED] Weird Spikes bypass UPS

[DondoFX]

So, I've moved to France for a year now, had shipped my PC here and started noticing that whenever somebody would start an appliance [specific ex: hairdryer, vacuum cleaner] or the fridge would turn it's compressor on and off, my TV connected to the PC would turn off and make sometimes some weird video noise, just like the no signal, at times would change to green too, sometimes recovering back to desktop, sometimes not [in these cases i had to disconnect HDMI and connect it back to have an image]. I already lost a motherboard because of these spikes [see my topic about videocard problem, it was in fact the motherboard] Changed both, mobo and gpu and still got the problem. Recently I bought 2 UPSes, one 330W for TV and other small appliances like modem and second monitor and today i recieved my second UPS 700W power APC UPS, and in the begining I was skeptical about it, watched whenever my fridge would turn on and off to see if the spikes persist even though the UPSes should clear the signals. Problem is... it does, sometimes. I still get the TV turning off but not as much as before. No noise appearing, just the TV image turning off and on. maybe a little artifact but quickly recover.
[it just did it again]

What the hell should I do to clean these power spikes? I can't deal with it anymore ruining my PC experience.[gaming is a bish when you're playing online and suddenly you can't see sht for a few seconds.]

What is happening, I believe is not "spikes" but brownouts. The voltage is dropping when a high demand device comes on. You may have to get a double conversion UPS. That is a UPS that is always running on DC and creating AC. It may be because of the battery of it may be because the UPS has rectified AC current into DC. A double conversion UPS always outputs a constant voltage.

A recording voltage meter could confirm my hypothesis above. Unfortunately they aren't cheap. You might ask your utility company to check the input voltage to see if it is in spec.

After buying two UPS'es for around 200 euros I finally ended the suffering with a 8 euro VGA converter. But thank you for clarifying the problem. Will come in handy in future maybe!
