GOOD NEWS: I finally got the
replacement power supply I needed, based on
this post.
BAD NEWS: ...My PC can't boot. Period. I never made it past the BIOS.
Based on yet more trial and error, I can only go as far as the BIOS Setup (F1)--IF I keep my SATA HDD disconnected! I can't even go to the boot menu (Esc) anymore!!! I had thoughts of trying the miracle of booting into CD-ROM to see if it were possible to clone a factory-restored HDD image from one USB HDD to another, and booting from it, just to see if I could reflash my BIOS to fully working order, but apparently, even that ain't possible! x.x
Oh, and the BIOS could see the SATA HDD, but it hangs.
So, apparently, I have a partially-working BIOS now, I'm GUESSING caused by the sudden heatstroke outages my PC suffered two Sundays ago. What do I do? (keeping in mind that I myself can't afford 'professional' PC repairs, as I just spent $60 on a hopefully much-needed power supply)
