My pc power supply keeps blowing up i had thermal tech 430 watts psu for about 8 months it was working great until one day it blew up. I got to my pc seller from whom which i bought my pc i have i5 3470, dell motherboard, 8gb ram and gtx 960. I bought another power supply a cooler master silent pro 620watts and after some time it blew on me again then i got my power supply repaired and bought a separate voltage stabilizer specially for my pc as advised by power supply seller and then my pc worked fine for some time like a month or so it always showed me high voltage red light on my voltage stabilizer and then panicking i always shutdown my pc and then again something blew up as i checked my voltage stabilizer 5amp fuse broke, what should i do? I'm scared enough to start my pc without the voltage stabilizer i have ordered online for a couple of 5amp fuses which will come till tomorrow, ill keep u updated plzz help me a bit im sick of fixing it again and again and im thinking of buying a gaming laptop after selling my pc.
Thankyou.

Get your main power line checked. Also check if anything is shorting the motherboard or any visible damages on the motherboard like bulging capacitors, blown capacitors, burn areas etc. Next time instead of repairing get a quality power supply like a Seasonic/corsair cxm450
