Built a PC, but no response

If your motherboard supports SATAII (and be sure you have it going to a SATAII header, some boards support both SATA150 and SATA2) and your HDD is SATAII... well, then you're running in SATAII.

When I have both SATA and IDE drives in the system, it will always try to boot from the IDE. I go into BIOS, it has both IDE drives and SATA drives listed, but only allows me to choose the IDE drive to boot from. How do I fix this?
 
In my BIOS there's the standard boot device order selection (HDD, CD, floppy, etc) and then a sub menu that lets you select which order he tries the HDDs. Maybe your board has something similar? Otherwise it's time to consult the board's manual...

Oh and be sure that you're running the latest BIOS version.
 
The BIOS is fully updated. When I have both IDE and SATA in the system, the BIOS sees both drives, but I only let me choose the IDE drive as a drive to boot from. The SATA drive is not on the list of the drives to be selected. When the IDE drive is removed, the SATA drive gets back on the list.
 
Try this and see what it does-

Set your CD drive's jumpers to be master, and the IDE HDD to be slave. Then get a 3 connector cable and plug them into the IDE0 header.

I can't imagine that they'd make it so the SATA drive can only be a boot device when it's alone. I'm really thinking there's a setting hidden in there somewhere, which is why I'd go digging for the manual if I were you.
 
Another problem is computer won't power off completely. Windows XP seems to shut down okay, the screen goes dark and all, but the power remains in the PC as fans are still spinning. My BIOS seem to support ACPI, as it has a separate ACPI section. What can be the problem?
 
Bad PSU? Bad motherboard? Bad BIOS? Wrong BIOS setting (check the power off feature) Malware?

Take your pick.

One thing to try - with the machine off, switch off the mains power, then hold the power button down. The PC will try to start with no power - the LEDs will flash, the fans will jerk, then all will be calm. Keep the button down for 10 second, let go, turn on the mains, then power up and see if it happens again.

It draws off stored power from all the capacitors in the machine. Solves this sort of problem maybe 1 in 10 times.

I'm betting the BIOS is set to "Suspend" or "Hibernate" rather than "Power Off" but I could be wrong.

Speedo, is that you trying to hack my system? Cut it out.
