Does anyone know how to test for a *DYING* (not yet totally dead) PSU?
Because I suspect mine is dying.
1) Random PC freeze during lightweight activities e.g. browsing sites, checking mail.
2) Sometimes when I power on the PC, the fans spin, the power LED is on but the system fails to post. Need to retry several times, while I hope and pray that it boots.
3) Sometimes it freezes while Windows (Vista) is loading, i.e. that black screen with a progress bar.
4) Freezing within minutes after successfully booting into desktop, while doing nothing. (This rules out a heat problem)
5) Freezing in BIOS!!! Hit DEL, entered BIOS, and freezes while navigating the menu with the keyboard.
6) Freezing before or during POST. For example, the first words you see on your monitor are that of your video card type and VGA BIOS version/year. My system froze there before it proceeded to detect for drives and devices.
This is frustrating and annoying, and now I have the phobia of turning off my PC when it boots up and is running successfully for quite a while (about 10 to 20% chance). Because I simply do not know if I can turn it on again the next time.
P.S: Inside Windows, the freeze does not have a BSOD. The mouse cursor just stops moving, and in any text input field the keyboard cursor stops blinking.
