Bookmark topic
My pc was workin normally till yesterday...but now the thing just won't boot! Seems like a power supply error. The lights come on for a second or two then goes off! Any ideas as to why the system would power on and then power off immediately? Surely, if the power supply has gone kaput, it shouldn't power on at all? Or is this some kinda safety mechanism?
Any ideas?

The difference here is... The system DOES power on everytime... But switches itself off in a few seconds.. The monitor does come on...sometimes shows the windows startup options and then powers off abruptly.. Sometimes the monitor won't switch on at all...

Well yes, that is power supply. Don't panic man, replace it first, then panic if it doesn't work.

@whiz
Some power supplies do have safety cutouts for surges, sags, overheat, fan not spinning etc. As johnex say's, it's more than likely just the PSU. I'd suggest that you don't keep switching the PC on until you get a new PSU though because if it is faulty, you might damage your motherboard or other components.

@cyco, some things i have noticed: the system for a while displayed a "CPU voltage error" (don't recall the exact text) just before it gave me an Irq_not_less_or _equal error just before the final BSOD message i received. The system hasn't booted properly since then...so i'm thinking on the lines that the processor is receiving a higher than specified voltage and hence the system shuts down to prevent damage? Is there any such safety mechanism in ACPI?
