Hi, My desktop PC, c 18mths old (Lenovo ThinkCentre) needs a repair as a) it is making an increasing amount of noise and b) shuts down after 30 minutes or so (increasinglly slow) use. Everything backed up!

Perhaps a problem with the fan? Anyway, any recommended computer repair firms. The SE23 mag always has an ad for "PC Repairs" (no address), but its interesting to get local recommendations. Thanks
