tidbit: just connect to your big screen and get a wireless keyboard and mouse
27"? try 60" and a nice comfortable couch or recliner.
just a thought... there are many reasons why a computer dies... you may want to yank out the hdd, then connect it to your new pc. boot up should load windows from right hd, but if it gives an option after post, select win10, not the old win 7.
once you boot up your new computer, see if you can access the old HDD. you may be able to recover things, besides ootp, that you want. you may need to enable it. disk management tools? somethign like that. assign a letter if it didn't get one, etc etc... make it active...
if the pc just started and never got past hte post (all the text you see before win starts to load)... you may want to try this:
unplug pc. press power button to use up any lingering electricity. open the case up.
physically swap ram around in the slots... if you have 4 slots, move 1 to 4, 2 to 3... a new seat should be enough -- also, try using only 1 or 2 instead of 4 and test each so that they are not bad -- in another "working" computer is best to ensure this.
Also, remove battery from bios/cmos whatever the word is... it's the only watch battery that you will see on the motherboard. Place it back in after a short period of time (3-5s). google your mobo for a schematic if you cannot find it.
try turning on the pc after this process. if oyu have a bad ram stick, that might be the only thing going wrong. the cmos should reset by removing the battery.. if it was corrupted, it might be fixed now.
if your pc does post, go into bios (usually hit "Del" when pc turns on) and load defaults.
anyway, alot of time there's actually nothing terribly wrong with the pc... just a little hiccup or a minor hardware issue (try 1 or 2 ram sticks at a time - some mobo require sets (2sticks - pair at a time), some do not (can use 1 ram stick at a time).
crystal diskinfo is an app that can assess the S.M.A.R.T. features of your HDD. it will tell you if it's having functionality problems. if i recall by rote c6 is a key one to look at - # of bad sectors or "fixed" sectors etc...
your hdd has X # of backup sectors for when some go bad. once this process starts it's not long before a hdd is useless. usually more than 30,000-40,000 hours are needed before this starts to happen (app has this info too). typically it will start to run at a snails pace before entirely breaking (snail = 1-4mb/s vs ~100+mb/s normally -- The OS will force pio mode)
in future if the app shows this occuring, get a new hdd ASAGDMFP (asap).. Just look once or twice a year and you will avoid losing all your data. it's good to be pre-emptive with storage.
c6 - "uncorrectable sector count" -- things will go badly, and soon... it may be "5" now, but within a month to a year it will escelate with an increasing rate of occurence... "0" is the only good reading here, unless you know you dropped it or somethign physical happend to it - still just maybe okay to be > 0.
(For anyone reading: Don't buy HDD based on RPM... Aerial Density is equally important... knowing one without the other is 100% useless information. for cheap hdd, the 5400rpm ones are likely the better choice and reach the same speeds with less heat and less noise.)
