My system specs are Athlon 1.2GHz 200MHz FSB Socket A Athlon, 384MB RAM, two Maxtor 5400RPM 20.4GB HD's, a 52X CD-ROM, a 24x10x40x CD-RW, two rear case fans, one front case fan,3.5" floppy drive, Geforce 2 MX 32MB, and a Zerus Twin Turbo 5.25" bay fan. Now to my problem. I've been watching ITE Smart Guardian and the 12V- drops down to 11.30V allot. The 12V+ drops down to 10.50v too, but less frequent than the 12V-. When I use SIV(from Gigabyte) on my Ath 800 the voltages are stable as could be and rarely jump up or down like the 12V- and 12V+ of my Ath 1.2GHz. Well, this morning and almost every morning I noticed my system locked up on me when it almost got to the desktop screen, but it was a black screen and a frozen mouse pointer. I hit Reset and it came up fine...... except the screen res was 640x480 and 16colors, when I set them back up to 1024x768 and 32bit color the computer froze again. Those are my indications of my bad PS. Will a new Enermax 350W Dual Fan Power supply stop the lock ups at boot and freeze ups in windows(i've reformatted 3 times) and keep the voltages stable?
