Anyone who saw my previous topic knows that I'm setting up a PC to eventually build. However, before I jump into the fire, I thought I would try and see how it's done by taking apart my aging eMachine... well, mostly I was just bored. Nonetheless, I took the PC apart (components only), analyzed the components' architecture, and the put everything back together (I double-checked). However, when I tried to turn it on, the CPU fan ran for about two seconds, and then it stopped. Nothing else even started. I tried pushing the button again, and this time the CPU fan didn't even respond. I've checked the power cables to the components, the fans, everything and they're all hooked up. I know that the outlet that I use is getting juice because I plugged my monitor in the same spot, and it powered up. All the cables are positioned the way they were before the dissection. What the heck could be wrong with this thing? Any assistance would be helpful.


(P.S.: Also, I sorta broke the arm of the CMOS battery holder when I tried to remove the CMOS battery. Obviously, trying to glue it back together would be ill-advised. Will I have to get a motherboard replacement as well?)

Bingo! If the battery circuit is completely dead, You have no BIOS. No BIOS, no computer. Did the arm snap all the way off?
You MIGHT be able to wedge a small gauge of single-strand bare copper wire or some aluminum foil in it to maintain contact and tape it all together.
If, by chance, you do get lucky don't forget to reset the date and time in the BIOS

Having grandkids is God's way of giving you a 2nd chance because you were too busy working your butt off the 1st time around

To avoid messing up my motherboard worse than I already have, I may just get an replacement mobo. Also, should've mentioned this earlier, I removed the CMOS about two weeks after the initial incident. Also, just for future reference, if I were to get a replacement CMOS battery, where would I get one?

All the drug stores around here have them. They're by the watch and hearing aid batteries

Cool. So I can just stop by Walgreens next time I have my prescriptions refilled. Well, is there any other potential reasons it may not be starting up (ignoring the CMOS scenario)?

Did you remove the heat sink from the CPU when you disassembled the computer? If so, and you didn't add new thermal compound when you put it back together the CPU could be overheating. Fix the battery first, Mark is correct, not battery, no computer.

Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.

If your battery holder is like mine, you can roll up a tiny piece of foil and with the battery in place, push it in the square recess with a toothpick. The foil should contact the broken piece of the clip. Then just tape it to the battery. Not pretty by ant means, but it will work
