my power supply which was a good one years back went defaulty and fried my hardrive, and motherboard so i had to replace all 3. does this seam truthful?
I question him and he said the Power supply was not providing enough amps anymore as the day I bought it. it just was not stable. Which was probably why your hardrive and motherboard died.
"A good one years back" Link us to the exact model, even some of the worst units will claim they are "A good one" and even some of the best brands have released a turd or two years back.
PSUs can get worse over time - and when they do go out they can take other parts with them.
What you should do: Replace the PSU with a nice Seasonic PSU (At least 80+ certified) and see if the PC boots. If it doesn't then the parts he listed probably did actually die. --- I think I'm the only person on gamefaqs with a daughterboard - ToastyOne New with a moderation history more plentiful than karma. - Fossil (Moderator)
The only way to know for sure is to start by replacing the PSU and test it out. I've heard of PSU's damaging other parts, but in the 5 years I've done computer repair, I've never personally seen it. --- i7 3770k @ 4.5GHz  HIS IceQ X^2 7970 |1200|1600|3GB|  16GB Ripjaws Z 1866  ASRock Z77 Extreme4  250GB Samsung 840  2TB Barracuda  CX 600 PSU  H80i
Could happen years ago I fried a capacitor on one of my mobos and the while mobo caught on fire...
Should have seen the panic.
Last time I seen a motherboard catch fire was when lightning struck the power pole outside of my work back in 2007. The dell's motherboard was glowing with all of the circuits where a bright white and smoking hot. --- I think I'm the only person on gamefaqs with a daughterboard - ToastyOne New with a moderation history more plentiful than karma. - Fossil (Moderator)
