This afternoon PC making qn intermittent grinding noise from one of the fans. Cleaned fans out still same so took it to local PC shop. They ran the PC for 45 mins and didn't make the noise sods law.
So I brought it home and now there is no power to it. Tried different cable its just dead. Off back in morning with it but odd how it worked 20 mins before in the shop. Wonder if the grinding was the psu dying?
