Ok...been fighting a technical problem for the better part of a week and I'd like to grab some advise before I start spending money or considering some more drastic measures.
My computer has been exhibiting the following symptoms:
- crackling and distortion through speakers while the computer is on and particularly during times when no audio is being played and I'm doing something like photo editing in Photoshop
- random and variable inputs from my X-52 HOTAS and Joystick (at one point when I was flying an IL-2 mission I could see the flaps going up and down rapidly and the throttle moving back and forth 1-2%)
- USB mouse connects and disconnects itself (just browsing a website) or exhibits random movements
- experienced several total system reboots
So far I've got Asus PC Probe working to watch the power inputs and I see the following (this is after a typical web surfing session, with mouse and joystick plugged in, and some music playing through Winamp)
There seems to be a fair bit of movement on the 5v display...is that more than I should expect? I've read several websites but not come to any conclusions on the matter.
I've also run Memtest86 and Prime95 in stress test mode (for 30 minutes) without any issues. So far the symptoms seem to occur at random times...typically I'm doing something so at idle it seems to not be a problem and I can stress the system right out and nothing will happen...OR it will happen.
My theory is that its either the PSU or the motherboard with me leaning towards PSU more than motherboard.
Any other educated guesses or feelings? I'm sort of stuck...but I figure if I have to chance it a new PSU is allot less of a problem to put into place than a new motherboard.
Important system specs:
AMD Athlon XP 2700+ (T-Bred B)
1GB of PC2700 RAM (2x512)
Onboard nVidia Soundstorm APU
XFX GeForce 6600GT 128mb AGP 8X
Antec TruePower 330W
The inside of the case is reasonably clean and isn't that dusty (dust filter is in place for all its worth). All fans appear to be functioning normally.
