Asus Probe shows a warning in my computer that there is problem with the 3.3V supply. It shows the voltage as 2.75 only. Till yesterday it was around 3.25V. For the last 6 months since I assembled it, there had not been any problem and all the voltage were well within the 5% tolerance. What may be causing the problem? Which components use the 3.3V. And what is the remedy? A64 3000, A8N-E, Transcend 512x2 -400, 80 GB Hitachi SATA, Sony DRU 810A, Priya 400W SMPS, 4 cabinet fans, Win XP SPII with all critical updates. No FDD Pl help.
