Sorry I think i was just having a hard time understand you. I don't think it's very likely that the power draw from a power supply is enough to power the computer and perform under stress, but at the same time as it's drawing enough for it to power, it's not drawing enough to be at a safe level of operating and it's damaging the motherboard/cpu.
This happened after a format.
Can you try reformatting again?
???????
what?
let me explain. when I moved to this house 8 years ago, this house had a old 100 amp fuse box and ancient wiring. we were replacing light bulbs at least once a month (they alway flickered) and they dimmed like crazy when using other stuff. our electrical stuff would die prematurely. we had 3-4 computers hooked up too. I was scared that the house would catch fire
in 2004, me and my electrician buddy pedro rewire the house. I got the 200 amp outside block for free, but I had to pay for everything. I bought 0000 also known as 4 0 guage wire and accessories to run from the outside to the inside of the house. I bought a 200 amp fuse box. we borrow my neighbor electric amd it took us a day to install most of the stuff (we did minor stuff the next day).
I ran a new line to the kitchen for the fridge and microwave. I ran a new line to the living room (I use a 30 amp circuit and ran 12 gauge wire instead the usual 16 for this one ) for the computer and stereo. I ran new 220 volt lines for the new electric water heater (to replace the expensive gas one) and main floor AC. I ran a new line to the upstairs for computer and the iron (for some strange reason they had the whole upstairs ran on 1 15 amp circuit). I did this to alleviate stress from the old wires. it too troublesome and expensive to replace them.
it solved all of my problem. the voltage was rock steady and solid in every room now. there is no flickering problem.
it cost me $300.00 in part and my buddy charged me a hundred dollars. my neighbor paid a electrician 6,000 and they put the same fuse size fuse box in which left them with a lot of the same problems
with electricity, you need rock solid stable voltage to ensure longevity. you don't get that by under powering stuff. I repairs computer for a living. I see this issue all of the time.
people buy a brand name computer that they already cost cut on it to keep costs down so they put the cheapest psu in it that they could get by with. then people upgrade and put a lot of stuff in it and overload an already taxed psu, then they wonder why it's dead
