I have actually just fixed the problem myself. There was a program installed called osd.exe, which is basically an on-screen display that show the status of various things. I have disabled it and now it all works fine! Just a shame that my treatment instore means that I will probably get my PC goods elsewhere from now on!

Hi all, back in september 09 I purchased 2 laptops, both exaxtly the same, on a Buy now pay later scheme. From the start there was a minor operational issue with both the units. Basically, when you turn Caps-Lock on or off, the screen freezes and the window that you are typing in deselects, meaning that you have to wait 3-4 seconds before having to reselect that screen to resume typing. I have lived with this since september but last week decided to report the fault back to pc world. The telephone tech-guys were helpful and arranged for it to be collected from one of the stores. I took the unit into store this morning to have it booked in for pick-up. The tech-guy in store asked me about the fault. After explaining and then showing him the fault he stated that it was not a fault but a feature of the machine and was not repairable. After discussions over my dissatisfaction I spoke to the manager who then informed me that as I have lived with the problem since september I have accepted it and have no right to any exchange/refund on the item! Needless to say I left the store with my laptop immediately and phoned customer service to express my concerns. After speaking with the online support I now have arranged for the unit to be collected from my home for inspection. What are my rights on this issue with regard to exchange/refund/etc?
