What Tobias wrote - voltages look way too much off. Onboard sensors are not always trusty, so I would go with real voltmeter. If you do not feel comfortable with electrical stuff, ask somebody for help. I would: 1. turn computer off, open the case 2. find molex connector https://en.wikipedia.org/wiki/Molex_connector#Disk_drive 3. pull it out of the case so I could reach it without touching insides of the case 4. turn computer on and start memtest 5. put black probe of voltmeter into black hole of molex 6. put red probe into another hole of molex (yellow or red) and see what voltages it measures Do not touch or move any cables beyound molex while the hw is powered on. This means if you move molex cable, it should not push on other cables - because some cables are very touchy touchy, like hdd data connectors. >From what I recall, PSU voltages are good when within +- 5% of what they should be. Yours look bad, because ~30% too big. Bear in mind, I am not electrical engineer. If you do not own voltmeter, this probably means you should ask for help of someone who does. -- Regards, Tomasz Rola -- ** A C programmer asked whether computer had Buddha's nature. ** ** As the answer, master did "rm -rif" on the programmer's home ** ** directory.
