[i built this pc myself 2 years ago]
I moved my pc from one house to another and was cleaning dust off the fans. I cleaned the PSU, heatsink, and video card fans. I took off the heatsink and vid card to wipe off the dust, the psu stayed in place. I turned on my computer and it was working for 5-10 minutes until it suddenly turned off. It wouldnt turn back on, i checked all the plugs inside, and when i'd try to turn it on the fan in the pc case would move a tiny bit and make a noise, but that's all that happened (the fan that is installed into the pc case). Then all of a sudden the pc turned on again but shut itself off after about a minute.
I figured the power button on the case malfunctioned and bought a new case(laugh), and plugged in the PSU, MOBO, PROCESSOR.. and all the fans turned on, pc fan, heat sink and psu fan.. lights and everything, then i turned the pc off (by the 1/0 on psu.. not thru power)... attached the gpu, hdd, and the pc wouldnt turn on again!! the pc fan did the same little noise.
any ideas?! so the psu has to work since the mobo light is on? the processor and heatsink work b/c they turned on after computer malfunction. Shouldn't the pc fan turn on when i push the power button? It's connected directly from the psu.. so from power button -> mobo -> psu -> fan. I'm not sure in what sequence a computer turns all its hardware on but im guessing th emobo tells the psu to turn on and power the rest of the system.
Thanks for reading!! and any ideas are appreciated.
