I recently bought a ECS K7S5A motherboard from maincomp.com, and have been having problems. I was using on board sound at first and would be in a game and all of the sudden a "shriek" would occur and my computer would immediately freeze. Sometimes I have to reinstall sound drivers, sometimes not, and sometimes I have to reboot 2-3 times to get my sound working. I then went and bought a sound card and disabled on board sound, uninstalled all sound drivers and installed drivers for the sound card. I've done everything possible as far as that. Today I noticed there was a system monitor program on the motherboard cd.. After installing and opening the program, I immediately got a warning saying 12v and 5v voltage was too low and could damage my system. The program is called "SiS System hardware monitor" btw... Under the 12V section it is showing 6.78v, and under 5V it is showin 4.04... all I have plugged into the power supply in my system is the motherboard, 2 hard drives (10gig and 4gig), and a processor fan is hooked up to the motherboard via the cpufan connector. Are these levels bad??? I/O voltage and Core Voltage are in the blue (so the program is saying its ok) I/O voltage: 3.31v Core voltage: 2.74v In the red (supposedly bad) 12V: 6.78v 5V: 4.04v Help? lol Not too much of a big deal cause I decided to ditch this new motherboard and get an Asus pretty soon. Also getting a Radeon9700 Pro real soon so I DO NOT need power supply problems. Oh yea, the power supply is a 400watt. Obviously cheap because it came with the crappy case.. the case + power supply was $27 + tax. HA, nice eh? Getting a Vantech 420w PSU soon though after I get a new motherboard.
