There appear to be lots of missing details here. After formatting C: I assume you reinstalled Windows? Where did you get your drivers and helper apps?
Greetings
Umm, so in the past couple weeks, my family pc has gone quite "rogue" on us. It all started when the screen started to glitch up and showed a blue screen, this repeated until I just left it alone for a few hours and it became normal again. My brother thought it was simply because of memory overload, and so I deleted some of my files (which he assumes are mostly the cause).
Then when everything was seemingly fine again, the glitchy screen and the BSOD came back. My brother then decided to reformat the partition with the large files (we have 2 partitions; C and D; and we backed up everything at D and reformat C)
But, everything went a little wrong, when after we reformat, it was able to boot but we'd get stuck on a black screen with only a cursor. Then a few days after, the glitchy screen and BSOD came back again, and this time it was worse since we couldn't even go to Safe Mode (or even use the Command Prompt).
So I'd really like to know how to repair this. I do have a choice of absolutely reformatting the whole drive, but if even that doesn't work, I guess buying a new unit wouldn't sound much of a second-choice.
