Spent 3 hours diagnosing a PC that just needed the CMOS battery swapped

Got a call from a buddy last week about his office PC that wouldn't boot past the BIOS screen. He said it kept losing time and date settings too. I spent almost 3 hours checking drivers, reseating RAM, even ran a disk check. Finally noticed the clock was reset to 2005 on a hunch. Popped in a fresh CR2032 and it fired right up. Felt like a dummy but learned to check the cheap stuff first. Anyone else have a simple fix that took way too long to figure out?

Man I felt that one deep. @valh32 totally nailed it with the power adapter thing too. I had a similar situation where my old Dell tower kept freezing randomly and I spent a whole Saturday reinstalling Windows twice before realizing the CMOS battery was dead as a doornail. Now I keep a pack of CR2032s in my toolbox because that lesson STUNG.

Man, @hugo_bennett that Dell story hurts just reading it?

Had the same thing happen to me with a router that kept dropping connection. Used to think complicated problems needed complicated fixes, but this totally changed my mind. I tore apart the whole network setup, swapped cables, even factory reset everything. Turned out the power adapter was just barely putting out enough juice and a cheap replacement fixed it in 30 seconds. Now I always start with the dumb stuff first, it saves so much time.
