Alright, so:
Yesterday, I decided to get a new case for my PC (as the one I had was giant and I wanted to make it more compact), so as I'm taking it apart, I discover something lying on the floor: a capacitor. The only place it could've come from is the motherboard. Still, I keep going, in hopes that I'm still able to get it to work without a capacitor. As I'm putting the PSU in, I accidentally slip and cause the PSU to fall...right into my laptop's screen, cracking it. So, after I finish up, I plug my recased PC in, expecting the worst...it works!
It worked all of last night with no signs of anything breaking, until this morning. I go to get on my PC, hit the power button and see the hard drive light flash, then nothing. I look inside and see that the green light on the motherboard is still lit, and then I try to turn it on again. Nothing. I remove all power (power cable, CMOS battery, etc) and put the motherboard into "recovery mode", turn it on, again, the fans barely spin and the hard drive light comes on, then nothing.
So now, I basically have a laptop with a cracked screen and a broken desktop PC, and I'm stuck using my Eee PC.
