I gathered all the pieces necessary to build a decent running computer to install ubuntu on to play around with. I couldn't even get the bios to startup. I got a no signal problem with my monitor.
I read through about 6 or 7 forums troubleshooting using others similar problems with no luck. Even tried just getting a signal by only having the cpu and heatsink installed and no beeping.
After some more tinkering, now nothing turns on. The only thing I see is the standby LED light and the power button light turns on. No fans, no psu, no whirring, no beeping, nothing. I started replacing parts until the only thing left the same was the motherboard and the case. The outcome is the same. Before running out and grabbing a new motherboard, I wanna make sure that there's nothing left to check.
The parts currently installed are as follows:
Intel D925XCV Motherboard
Intel Pentium 4 640
2x hp 512mb DDR2 Ram from old computer
ASUS HD 5450
I don't know how much experience you have with changing motherboards, so can't tell if a mistake was made. The usual suspects: one bad ram stick, bad or flaky power supply, etc. Try just one stick in dimm slot one. Also disconnect the hardrive; you just want to see a post screen. But I've seen bad boards that will post, but windows won't finish installing. Windows is a great way to check your board and ram; if something isn't kosher, it won't finish installing.
