is it the PSU's fault?

[omgitslong]

I ran memtest86+ for an hour in the morning when I just turn on my computer, and it ran error-free. But after ~3-4 hours of usage, I noticed it
s getting unstable, so I restart it and run memtest86+ again. This time, it shows tons of errors. But if I shut the computer down for like an hour, turn it back on again, and then run memtest86+, it would run error-free again. And pattern begins....


Is it my stock 420W that came with the case that's causing the problem??


PSU brand: TurboLink,
17A : +3.3V
25A : +5V
14A : +12V1
14A : +12V2
1A : -12V
1A : -5V
3A : +5Vsb


I did not trust it in the first place of building this first computer, but I didn't have enough money :x so I'm living off of it for like 1-2 weeks until I have the money to buy a new mid-range PSU.


And last, what do you guy think about this PSU??

Purists say you should never use a c**p PSU that comes with the case, but I have built 31 computers, all except one had case PSU's and I have never had a problem!

Could be a memory fault, but there is no harm in updating to a nice new style PSU. They look really good in the PC magazines

Don't go from one crappy psu to another crappy psu. what is your budget? spend at least the cost of your motherboard on a psu because if the psu goes it will take the motherboard with it...

Could it be that your memory is just overheating and you need more cooling? memtest86 does bang pretty hard...

What kind of memory are you running? What MB, what CPU, what GPU? How many fans? How many hard drives?

28A on 12V, 25 on 5v, 17 on 3.3, isn't too bad at all for a minimal system, what else is in the case with that dual-rail 420 watt generic power supply? You may want to check if there could be another reason for memory failing before you spend $100+ on a PSU and wind up with not fixing the root-problem...
