Overheating or wonky power supply?

OK, I've been running the following system for nearly a year now and only recently have begun running into trouble. This may be heat related, but I'm not 100% sure, and not really sure how to check.

Raidmax Scorpio 868 case
420 Watt P/S (came with case) - one fan at rear of case
DFI NF2 Ultra LanParty mobo
Athlon XP 2700+ (non-Barton)
Corsair XMS PC2700 512MB CL2 RAM (currently running at CL2.5 as a test, but still see lock ups)
ATI Radeon 9500 PRO 128 MB AGP
WD 120 GB SE HDD (8 mb cache)
Asus 52/24/52 CD-RW
Coolermaster Aero7 CPU fan
Two 80mm exhaust fans in back, one 80mm window fan
Rounded IDE ribbons to cut down on blocked air flow within the case, and fairly tidy cabling otherwise

Doesn't really seem to matter what I'm doing with the system - it could be sitting idle (which is when this normally happens), and it will just freeze forcing me to power reset it. I live in Florida and am in the second story of my house, so yeah, it gets hot during the day, so that's why I thought heat first.

There is room for 4 more case fans at the front of the case (if I can figure out how to get in there to attach them), so my question is do you think this will help?

Also, I am planning on replacing the P/S with an Antec TruePower550+ in the not too distant future in case I'm dealing with a crappy P/S, but I figured 420 watts should be enough for what I'm dealing with at the moment.

Any thoughts or suggestions would be greatly appreciated. Thank you!

P.S. I checked the system BIOS the last time that I rebooted my system and here are the running specs:
System - 40C
CPU - 52C

+3.3v - 3.34 - 3.37
+5v - 5.08
+12v - 11.97 - 12.03
-12v - -13.26 - -13.18
VBAT - 3.18 - 3.23
5VSB - 4.99 - 5.01

I do not know what the last three items are or mean so cannot even venture a guess at whether these are good / bad / indifferent.

Yeah, seems to be on the warm side unless ur OCing. Can you take off the side panel and use floor fan or similar to blow air in it as a test to see if, in fact, heat is the prob?

Got a spare psu? If it's a cheapie psu, I'd be suspecting it for sure

I'd prolly run memtest86 just to check the ram as well.
