Working on an HP Pavilion P7-1380T, Windows 10.
I turn on the computer, I hear it fire up, but nothing shows on monitor, keyboard light doesn't come on, and the hard drive light on the computer doesn't come on. It just sits there. Hitting keys doesn't do anything either. If I let it sit for a while, the computer will reboot and sit there some more.
Here are some things I've tried:
1. Removed connections to CD drive and HDD to try to get it to at least POST. No joy.
2. Removed one of 2 sticks of RAM to test theory of bad memory. No joy.
3. Removed all connections to MOBO and re-connected them. Nothin'.
4. Swapped out monitor. Didn't help.
So at this point I'm guessing I have a bad CPU or MOBO. But I've seen others who have this issue that end up figuring out it's a bad hard drive, which if true is really weird because it should at least POST in that case, right?? I also don't have the parts laying around to test my CPU or MOBO theory.
Anyway, could really use a little help here.
Thanks guys and gals!
