Well, the 350 watt generic spare PSU that I replaced the failed 400 watt that came in the system became very unstable yesterday.
I noticed the cpu fan was spinning at full speed all the time (I keep the case open at all times for extra cooling) and thought that it must be with the warm weather. Switched off last night to give it a break, back on this morning, same thing, except the weather was cooler here this morning. Only then did I think to check the PSU fan, and yup, it wasn't spinning. Have cleaned it out and managed to get it spinning again but gives up every 30 or so minutes!
I know I shouldn't be using a crappy generic unit, but never got round to replacing it properly. So, now I want at least a 500 watt because I am planning on getting an 8800GTS in 2 or 3 months.
Here's the rub....I have only about £35 to spend, maybe £40 at a push for the PSU because I also want to get a new CPU fan to replace the (bloody noisy!) Intel original. It's a P4 3.2, limit of about £15 - £20, enough? Any recommendations for either or both would be greatly appreciated.
Thanks a lot guys.
