the ram has been tested the cpu has been changed im using the bios and speed fan to check temp so i have just forked out £70 for nothing when its the motherboard
The people on this forum are just trying to help. When several people who probably know a fair amount more than you suggest you change your PSU then I suggest you do it and thank them for that advice. Although it didn't fix your problem, running a £20 PSU is like running your PC with a timebomb inside. That £70 you spent 'for nothing' is probably the best £70 you've ever spent, regardless of whether you know it or not.
