@Phaedrus: Yes, but we/i still haven't figured out where it's coming from yet, and moving individual parts out to listen to is useless because it only makes the noise when i'm in windows.

@greenbrucelee: Well i suppose i am worrying a bit too much, but i just haven't got closure on whether or not it's actually a problem yet, i mean the original person (Chris) did say it was not an issue, but he didn't hear it when it was pulsating (sometimes it just whines, other times it pulsates) and i really do not want this PSU to die; judging by a past thread response my PSU is crap, and chances are will take out the rest of my PC with it when it dies.

Besides i've had a sort of "breakthrough", i was listening to the noise when i launched GIMP (image editor for those who aren't aware) because it uses the HDD quite a lot during startup but doesn't take that long to load so it's useful for testing, anyway when the HDD was accessing the high pitched noise was affected by it; i can't quite describe it but it just sort of went quieter the more the HDD was being accessed during GIMP startup.

Edited last paragraph from above post, didn't let me edit the post:

Besides i've had a sort of "breakthrough", i was listening to the noise when i launched GIMP (image editor for those who aren't aware) because it uses the HDD quite a lot during startup but doesn't take that long to load so it's useful for testing, and COD 4; and the noise seems to be affected when the PC is doing something; i can't really explain what it does but if i do something like launch a program or join a game (loading the map) the noise will sometimes stop for a second or get quieter as it's doing something.

greenbrucelee

can you record the noise on video and post it on here or put it on youtube?

macgta16

Nah, unfortunately it won't pick it up; it's just too high pitched/frequency. The only thing i can compare it to is the sound a CRT TV makes when it's turned on, except quieter, and slightly lower pitch.

greenbrucelee

That could just be the standard hum from a psu, if you were having problems you would getting BSODS and freezing.

macgta16

Ah, it's just none of my other PC's make that noise, and it's just strange how it only does it when windows is running. Either that or i just haven't noticed it on other PC's; I could try booting up my old PC to see if that does it as well.

macgta16

so basically you're saying that if the humming was bad i'd get frequent BSODs and freezing? I was jus wondering why it only does the noise in windows.

greenbrucelee

check event viewer and see if you have any errors in the system log or application log

macgta16

errors like what?

wrench97

When windows loads the drivers it puts more of a load on the system then the Bios or even linux will in most cases.

macgta16

What sort of errors am i looking for in the event viewer?

wrench97

Any errors.

greenbrucelee

yeah any

macgta16

OK, i can't check it atm, i'll have to do it tomorrow; but i can remember an error about something called "WMI" popping up occasionally (i had to check it a while ago for a crash dump) Not sure if that's anything serious but i'll have to check it tomorrow. Also, i can't believe i didn't mention this originally but i presume this is related to my PSU. My monitor has faint horizontal bands (about the same size as a ruler but a bit smaller) running up and down on dark colours, most noticably when in games (it does it in windows desktop/firefox etc... but it's harder to see) it's done this for quite a while (longer than the noise) and i've just put up with it so far. I read that this could be to do with the PSU as well, not sure if this little snippet of info helps.

greenbrucelee

yes the psu may be struggling to handle the graphics card and the graphicsd is in turn failing this could have something to do with the noise.

macgta16

Right i checked the event viewer, and there isn't any errors at all except from WMI again; (error: Event filter with query "SELECT * FROM __InstanceModificationEvent WITHIN 60 WHERE TargetInstance ISA "Win32_Processor" AND TargetInstance.LoadPercentage > 99" could not be reactivated in namespace "//./root/CIMV2" because of error 0x80041003. Events cannot be delivered through this filter until the problem is corrected.) but it's done this since i got the PC, and i only noticed it when i searched for it.

@greenbrucelee: So basically my PSU and graphics card is dying?

greenbrucelee

Sounds like it. go ito the bios and post your voltages and temps

macgta16

Have done in a previous post; i don't think i've done the temps though. I've also had another issue which points to PSU; When i was typing in something in google it just stopped typing (keyboard froze) the caps lock/num lock icons weren't working, and when i checked the PC i heard a buzzing until i unplugged and plugged the keyboard back in. I think there is definately something wrong here; i'll post the temps + voltages from the BIOS in a minute (need to restart PC obv.)

greenbrucelee

locking is usually associated with bad ram or psu

macgta16

OK;

Voltages:

CPU Vcore: 1.296v
3.3VCC: 3.424v
12V: 12.144v
5V SB: 5.107
GPU voltage (off HWmonitor): 1.26V

Temps

BIOS:
CPU temp: 35c/95F (41c in Windows)
Sys temp: 28c/82F

HWmonitor
GPU temp: 51c/125F
HDD temp: 27c/80F


I presume the keyboard locking would be the PSU, since when it locked, i checked the PC, and it was buzzing until i unplugged the keyboard, and plugged it back again.
