First of all, sorry if there are any Engrish. And sorry for the quite long post because I tried to explain my problem as clear as possible.
To avoid TLDR, this is my question: can USB devices cause problems with the computer power, specifically the CPU fan?
I have an about-one-year-old PC built from a modified tomshardware's December 2012 $500 Gaming PC: (Pentium G860, ASRock H77M, Corsair 2x4 GB, GeForce GTX 560, 500 GB SATA3 Harddisk, Samsung DVD Writer, Corsair VS450 PSU). It works very well for me (although it can't play newer games at maximum setting, perhaps because of the G860).
After a year, things get dusty. So, I opened the case, plugged off all cables, cleaned the dust, and plugged everything backward again. The PC works well, but suddenly it turned off by itself when I was working. I turned it on again, but nothing shows up on the monitor. I opened up the casing again and checked if there are any mistakes in plugging cable. There wasn't. I noticed that when I turned on the PC, the CPU fan wasn't turned on, and the PC will turned off by itself after several minutes.
I tried to reset the CMOS BIOS using the jumper, and the PC turned on again (the CPU fan also turned on). However, it suddenly turned off again by itself when I tried to login at Windows 7. The problem appears again (CPU fan wasn't turned on).
I tried to boot up the PC using minimum devices (with harddisk, keyboard, mouse, and monitor). The PC turned on and everything worked well. I plugged on the DVD drive and still no problems. I tried Bioshock Infinite benchmark to stress the PC, still no problems. The PC had running without problems for over a day now.
At this point, I suspect that the problem lies in USB devices I used. I used these USB devices: a 4-USB hub, printer, scanner, USB keyboard, USB mouse, a gamepad, and a USB cable (to plug in USB keys). I haven't tried plugging each of them again, but I'll try meddling with them as soon as possible (I'm currently traveling away from my PC).
This is my question: can USB devices cause problems with the computer power, specifically the CPU fan?
Thanks in advance.
