I decided to give my PC a clean this morning. This included taking the heatsink off the processor to give the fan a clean (it looks like this if it helps).
When I turned the PC on again I got a repeating, long, high pitched beep (no distinct number of beeps).
I'm not sure about exact models/numbers but it's a Foxconn motherboard with an AMI Bios chip. I've had a look at AMI beep codes but nowhere mentions the beep I'm getting.
I thought I may have ruined the thermal paste so I'm going to get some more. I've also tried with nothing plugged in in the back (keyboards/mice etc. Still have everything internal plugged in) but I get the same problem.
Is this beep code something standard?
Note: I'm not at home right now so I can't find model numbers.
