PSU, motherboard or something else!?

I've put up with this since early 2006 believe it or not but it seems now its gotten worse, cold boot freezes on the windows loading screen, seems to be exactly when the fan noise becomes quieter, the thing is i turned off cool 'n' quiet but it still sounds like the fans change speeds, worse still it now does it more often, not only on cold boots but even when its had power for sometime, it used to be once a day when i first powered it straight up, unless i left power to the wall socket on for up to 30 minutes (pc not actually on at this point), i have a feeling its the capacitors somewhere as this would explain why that worked, so now im wondering what to do? :confused:

I was thinking of getting a new psu but i don't know whats good these days and if im to get one i need it to be future proof for next year when i get a new high end system, my psu is an antec neo power 480w v2.0, motherboard is an A8V deluxe, i think those two are the main suspects, everything else is decent quality stuff for the time, which was bought around early 2005, i don't overclock and don't have a lot of stuff using power so i believe it may be the capacitors or something else power related like the fans changing speed at boot, the system runs good all around apart from that, would appreciate any help, thanks! :)
 
I only put the two main suspects because the rest is pretty usual and was decent quality at the time, antec neo power 480w v2.0 psu, 3500 64bit athlon, A8V mobo, 1GB crucial ballistix ram, sata 74gb raptor main hd, sata wd se 8mb 200gb storage hd, 6800gt graphics, audiophile 2496 sound, 108 pioneer dvd drive and a floppy drive.
 
Before you look at the PSU.. Have you checked that your memory is receiving the correct voltage requirements. Might be worth visiting the RAMs manufacturers website to check the VDIm requirements. You may need to set this manually in the BIOS.

Might also be worth running memtest86+..
 
Ah good idea, thinking about it that crossed my mind once ages ago but i forgot to try it, i've done a memtest before and it seemed ok though but in the bios most stuff is on auto so its worth a shot, thanks.
 
Im pretty sure the crucial ballistix ddr pc4000 ram i have is 2.8 volts but when i did this after a while the system froze twice when loading a game so somethings wrong somehow, im not sure what to do about it, i put it back to auto for now? :confused:
 
Shouldn't be necessary .. the timings for those modules are 2.5-4-4-8 . so try the timings on auto but make sure the vdim is set to 2.8v

When you are happy that the memoryu is ok, check the PSU..

Give this a read...

Yeah im pretty sure the ram is 2.8v but when i changed just that from auto thats when i got two crashes in windows on loading a game up, the timings were left on auto, because the ram volts caused a crash its making me wonder if it is indeed the ram, im not sure what to try now? Nice guide by the way! :)
 
This is strange one, after trying various stuff i managed to narrow it down to a lan related problem, in the past safe mode has always worked ok but when trying safe mode with networking for the first time that failed too, so i decided to try turning off the motherboards lan in the bios and guess what it booted up fine, after trying this a few times over a week i was sure that must be it, of course i need networking so i thought i may as well add a cheap network card, well it worked right up until i loaded firefox then it happened, i just can't understand why it does this! :mad:

Are the PSU rails stable and within the acceptable tolerance?

Apologies for the delayed reply, looking at asus probes voltage monitor over time i see the 12v rail is at 11.84 with tiny pixel sized fluctuations in the line now and then, 5.026 and 3.312 are stable lines, vcore is around 1.358 though cpuz shows 1.408 to 1.424! :confused:
