PSU problem i think

[dgreensl]

Ok this problems got me stumpt. Lemme spell it out for you all and see if any one's got a solution up your sleeve.

The problem: Computer works fine in windows , go to play guild wars after about 15 min the whole computer reboots. As i start playing guild wars the PSU of my computer starts making a clicking sound. Like a base bal caard in a spoke.

My Rig:
Epox 8KRA2+ with AMD XP2600
1 gig of ram
ATI 9800 pro
DVD drive
CDRW drive

Aditional points of interest:
ON boot up the computer used to say XP2600+ now it just says KT600 DDR
Voltages:
Vcore =1.66
Vagp = 1.47
+ 5 = 4.83
+12 = 12.5
Vio = 3.24
Vdimm = 2.51
Vbat =3.12
5VSB = 4.89

I have been smelling a melting smell occasionally.

I have been having some video card probems as well recently, the card was over heating. Blew a fan across it and solved the overheat problem. I'm wondering if the card isn't getting enough power and is having problems functioning or what. The specs on my PSU are as follows:

+3.3 = 25A
+5 = 38A
+12 = 17A
-12 = 0.8A
-5 = 0.5A
5VSB = 2A

it is an Apower 500W
From what i've read here and there i think my +12 is wimpy for the rig i got and is starving the system for power

Thanks for any input

I would firts check ur cpu temps
if there normal see if u can test with another psu, the current one u have should be more than enough but ya never no

Sorry my CPU temps are 33C system and 50C processor.

I installed Speedfan, at a suggestion from a roomate, It's reading my -5 and -12 volt rails as -5 .18 and my -12 at 1.79 that seems bad to me

 

[impudence]

uh yeah

 

[montag451]

Can you just check it wasn't 11.79v?
If it was 1.79v, I'm surprised you get past POST

Ok put in an old PSU from my server 300W but on bare bones should be ok get the following: Vcore =1.66V, +3.3 = 1.49V, +5 = 4.76V +12 = 12.46V, -12 = 1.79, -5 = 0.18 , 5VSB = 5.4V, and Vbat = 3.12 V. hmmm, I'm gonna try switching out my Graphics card an seeing if that solves a few problems or not.

ok i put an old GF2 in and things didn't really change...
the only significant change is that +12 drops to 12.2 V. Something seems wrong i just don't have a clue.

Appreciate any suggestions on work to do to diagnose this problem. Thanks all
