Re: Optiplex GX100 - Cap failure? [NooB]

thanks for the quick reply. The CPUs should both be okay... they worked this morning [the 733 in another computer]...
Are those things Transistors, then, and do they look busted?
PS. Ah. It's a VRM Mosfet, eh? I'll go look that up.

Today I tried upgrading my Optiplex GX100's Celeron 433 to a Celeron 733 [I didn't think it'd pose a problem as they both use the same socket]...
After I plugged all the peripherals back in and pushed the power switch, it powered up but nothing showed up on my monitor. After about 15~30 seconds of noise and activity, the computer abruptly shut down.
I immediately opened the case and attempted to boot again. As I watched, there was a sudden emision of smoke from the area a red and white arrow points to it in the attached picture. The air also stank.
I immediately unplugged...
