|So I made the stupid mistake that no man should make and bought a cheap PSU off ebay for an old PC I was putting together to make an HTPC. After very little use I got a smell of burning and nothing would come on the screen. Fans whirred as and all the lights came on.|
I replaced the PSU with the one from my everday PC but as expected things were the same, so something has clearly gone wrong permanently in my HTPC. I tried replacing the graphics card to no effect and tried removing the RAM or the graphics card to see if the PC would make its usual beeping sound to tell you something was missing, it didn't.
So clearly the problem lies with the CPU and/or Motherboard (and maybe the RAM but we haven't got there yet!). I tried removing the CPU and turning on, this caused the PC to react exactly the same, suggesting a CPU problem.
Now what I would like to know is when PSUs normally go what components normally go with it? From what I've told you does it seem that it might be just the CPU which has gone? If both have gone its an annoyingly expensive replacement for old components!
