URGENT HELP NEEDED

[NukaCola]

My original OCZ PSU died on me a week or two ago. I got it RMA'ed and they sent me a new, better PSU (600W as opposed to 520W).

I installed the PSU, connected everything, the PC powers on no problem, but after the CMOS check and everything it suddenly says DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER.

What is going on? What do I do? I have three harddrives:

250GB SATA w/ WIndows XP installed on it

500GB SATA (just files and stuff on it)

160GB IDE (just files and stuff)

What's the deal here? Please help. Thanks.

UPDATE: I unplugged my 500GB SATA and Windows booted fine. I then checked BIOS and changed boot priorities. IT'S ALL GOOD. Problem solved. Deep breath. Phew.

BTW, how can I get my mouse to be recognized as USB instead of PS/2 (I have it in a USB --> PS/2 converter, but when I plug it in as just USB it won't work in Windows XP)

Odd that USB mouse doesn't work but check that you have USB mouse enabled in BIOS.
