199706 2003-12-12 02:15:00 I've just been using AIDA32, and I've realised that the "5v" inside my computer is actually running at approx 4.25v. Is this likely to cause damage to devices such as hard drives etc.? somebody (208)
199707 2003-12-12 02:21:00 How are you measuring it?

Aida will just be reporting what the cheap A/D conversion chips report I suspect. They are *very approximate*, like the temperature.

Use a quality multimeter. The answer will be quite different (I have seen 0.5 volt difference as an example)

Before it could "do damage" the PC would shut down/freeze etc. Of course this may be the damage you refer to? How oftem is this causing a problem (or is the only problem that you now think the voltage is low?)

199708 2003-12-12 04:02:00 Thanks Godfather. I was just using AIDA to see what it said (was actually checking temperature at the time, but the voltage stuck out). I'm just a bit scared to use my multimeter on it while it's still switched on, but hopefully it won't do any damage.

I'll have a go with my multimeter, however it's one of those cheap Warehouse ones so I don't know how accurate it will be.

199710 2003-12-12 05:03:00 Even a cheap meter will be more accurate than a motherboard sensor I suspect. But I agree, leave it alone, or keep fixing it until it breaks. godfather (25)
199711 2003-12-12 08:39:00 Fair enough. I'll wait till there's a problem before I go about testing it. somebody (208)
199712 2003-12-12 09:49:00 Getting readings from software may not be accurate with some PSU/Motherboards. Try viewing it from the BIOS instead. utopia (2200)
