The other day my PC simply shut down and it simply won't turn on, no fans turning on, no lights, no sound, nothing...
I'm pretty certain it is the PSU and the PC should be under warranty, but the repair should take two weeks minimum.
Money is tight, so I'd rather have it fixed for free, but the wait is just too long so I think I can afford buying a new PSU, but only if I'm sure that the problem.
I've heard it's possible that the PSU can take everything with it when it dies, which is what worries me, I can't afford the spend the money on a PSU if everything is dead!
I had a similar problem last year and I could swear that when they fixed it under warranty they put some white sealant or coolant gel in the PSU, because I'm sure those white globs aren't normally there.
Anyway, any advice is welcome, but take in mind that I can't afford much now.
yes,your psu is 100% dead because it is not at all giving a slightest output.
Don't worry your other hardware will be safe but to make sure get a psu /borrow it from someone and try it.I am pretty sure that it will power your system and will let you use your system.
I am pretty sure that it would not affected your hardware because one of my friend's psu died and it was also giving sparking when the system was switched on.When he got a new psu his system perfectly worked without any problem.
In simple don't worry just get a new psu or get the old one replaced.
