I've been having a terrible times with my PCs. I do stack up back-up machines fanatically, as I've been through real weird moments without a computer to login. Freak world, all my 5 machines got some problems. I cannot use any of them now. And I'd been using my phone to connect to my teams for all my interactions from yesterday. It was highly crippling.
Now the 5th machine to go down, was a Dell OptiPlex desktop. I never used it much, it was always on the shelves, sleeping. I took it out, installed a fresh copy of Windows 10, but when installation was on, I had to leave the machine and go out. I could only come the next day, installation was done but I found my keyboard & mouse frozen. I couldn't finish the installation by answering the set-up wizard.
I had to do a hard reset. When I switched off the main and switched it On again, The display wasn't showing up.  I was just relying on this machine as a final hope. I screwed it up.
I thought I had burned the Graphic card. I removed it & tried to connect to onboard graphics. Nothing worked.
Then I stopped & looked at the CPU BOX , it was showing "3-4" in Orange LED. It struck me! I have never seen these codes before. Then I quickly googled for it, it was just pointing to the DIMM memory errors(RAM). How handy these orange LED codes are!. I just precisely removed the RAM chips from these slots & got the machine back on. 
I usually detect the RAM failures with a long beep the machine throws. Don't know why this DELL BOX didn't do that. Anyway I just loved the orange LEDs talking straight. amazing. Thanks Dell. 
I love these extra care hardware makers show. Even the CPU box, Heat sinks were nicely done.
(btw, I'm seeing a new ORANGE bulbs at the head of each post here in Lounge, wondering if it's indicating something  )

Had similiar experience a few weeks ago; went to fire up la machine (Optiplex 980 / Win 10) and nothing. No beep codes emitted to try and decode. But I did have the pair of orange LEDs which were going at it. Checked support and said memory issue. R&R'd the DIMMs and working fine.

Just noting the possibility that maybe you knocked it up a bit and maybe they jiggled loose.

Yup, something jiggling loose after a few months is usually what happens after getting knocked up.

Widespread problems across multiple independent machines like you're describing could point to a bad power source - do you get brownouts in your area? Too much crap all running off of the same circuit? Refrigerator or power tools nearby?
Actually the first question should be, are you using a good UPS?

Its connected to a 1KVA sine-wave inverter line. I've spent enough money on these. But though its connected to the inverter, I'm not sure if flucuations in main line would affect the systems or not. I need to get a clear idea on this before I lose more money replacing my hardwares. All machines are even connected via a spike-guard. Display cards, Adaptors, memory chips has been the primary victims.

Dry area, causing static electricity then? Any carpets?

No carpets , and our place has more humidity.
I checked with one of the hardware guy. He's asking me to check with an electrician. I dont have clue how they are going to check it. We don't have a "NewRelic" for power supplies to monitor and warn things. When electricians check, I think they are just going to say it's all perfect. Is there any way we can measure the fluctuation on a longer run? May be it's happening couple of times per week , dont know.

I'm really not in any position to offer much more beyond this. Based on what you described however it's really difficult not to look for some external factor that's affecting all your hardware, especially if you have other appliances or devices, like TVs or DVD players or game consoles, that also have had a short life.

Sure np. thanks for your replies. Home appliances, the electrical ones all have had a healthy long life. May be the electrical disturbance is tiny enough to attack digital ones. TV, Dvd, etc - I don't keep them ON most of the times. So the chances of getting hit might be lesser. I'm gonna check with the electrician and see if we can troubleshoot this clear.

I wouldn't mind a follow-up after your electrician's assessment - I'm genuinely curious. I'm sure others would be too.

Sure I'll post the details

Nice one-liner, but it is an empty statement

{}; could be. Is an empty codeblock a statement, or is it a block that contains no statements? I figured the latter one
