I had two such issues with building my own (only an amateur enthusiast). The first time I built a budget computer for about 400 bucks, and the cpu fan died after two years. I replaced it before it died, but the cpu still managed to burn out within six months of the fan replacement (maybe I fucked up the thermal paste application somehow?).
The second one I built last about three and a half years, but the motherboard somehow went bad and it won't start. I didn't move the parts cause they were pretty well outdated anyway (old amd athlon single core, 40gb hd, radeon 7500, not worth saving).
My dad bought a dell before I built that, and that thing still works after 6 years. He's had to replace his hard drive, and his dvd drive broke (I just gave him the one from my second rig), but I'm just shocked that thing still runs. He only word processes, browses the internet, checks e-mail, and plays solitaire so he doesn't have any need to upgrade so he says.
Dell's cheaper parts may be slower, but have outlasted anything I've built with $500. Is that just cause I suck, or do you guys replace your pcs often? When my Dell dies (been 2, hopefully in 3-4 more years), I plan to build my third pc, but don't want it to die that fast on me. I have learned from a few past mistakes, stock cpu fans from amd/intel suck. I think I'm just going to get watercooling next time. Also going to get the largest/fastest hard drive possible, two years ago I was like 160gb is enough space
