Hi all RISC OS X-scalers, Nixiyo, my X-scale RISC OS 5.13 computer, often freezes at some time during boot-up. This can be anytime during pre-desktop through to desktop. I know this has been discussed before, but after searching the freelist archives I can't find quite the answers to my queries. Nixiyo never falls over once he gets through boot-up, in contrast to what some others reported. The problem is becoming more frequent, but re-booting is nearly always successful (occasionally I have to re-boot a second time). When it happens nothing works and only a re-boot gets Nixiyo going. I know that some say the PSU is at fault. What is the price of a new PSU? Is there a recommended make/model? Can a non-expert fit it or do I take it to Castle or RISC OS dealer? If Nixiyo's PSU is not at fault, what could cause it?
