Continuous hardware problems

[crumornus]

So about four months ago a friend of my helped me build a computer. We installed everything and it worked fine for a few hours until the PSU died. So I sent it back and got a new one, and everything was working fine for about a week. Then one day my computer was unable to start due to some smart health status thing that said my hard drive was bad. So I sent that back to and got a new one. Everything worked for about 2 weeks but then my computer kept getting blue screens every time I tried to start it up. So I tested my RAM and it failed Memtest, so I sent it back. I just got the new RAM today and installed it into my mother board. But when I started my computer up I continued to get the same blue screens. I talked to my friend and he said that the next most likely cause of the problem might be my mother board, but suggested I make a post on here.

If anyone has any advice for me it would be much appreciated.

Also the only things that I have not replaced are my CPU and my motherboard, so should I just get them both replaced to be safe?

more than likely your psu dieing killed your hardware and it all needs to be replaced

I agree the PSU could have corrupted your parts. Do you have another computer you can test your non-RMA'd parts with?

I second that the motherboard is probably toast. Odds are your other components were not bad at all but rather that the mobo was the problem all along. I seriously doubt that your CPU is damaged as they are tough little buggers.

Also, Pyrothrillah's suggestion is a good one. I would try ALL my parts in a different computer if one is available. Do them one at a time and test each one.

What i Would try is checking what kind of hard drive it is. if it's a SATA drive make sure you bios reflect this. if it's an IDE same advice. check you mother board battery.
