Random BSODs with random causes

PC Specs are below. This is a Windows XP 32bit machine that keeps having very random BSOD often with different causes. I've had it stable for weeks on end doing everything from heavy gaming to just web browsing. Then other times gaming will cause it, but mostly just have a music player and web browsing. I've ran memtest86 with no errors. Dump files are attached thanks for any help in this matter.

OS: Windows XP Pro SP3 32bit
Mobo: Asus M2N SLi-Deluxe
CPU: AMD Phenom x4 9850
Video: eVGA GTS 450

What antivirus/antimalware programs are you running? The minidumps show "LF30XP.sys" (Lock Folder XP) Do you have this installed? The minidumps also suggest general Windows instability. What is the power supply's make and model number? How old is it?
 
I'm running Zone Alarm as firewall, NoD32 as AV. LF30XP is a folder hiding software. Power supply shows 11.5 on the 12v rail from software but test 11.8 at a molex on DVM. Do you think I should get a new PS? Thanks for taking a look.
