Ok, I've had the current PC sinc february this year, bought it from my local PC store so it's not a brand one (like HP or Dell etc) they built it themselves. Its running Windows XP and some of the programs I've loaded don't/won't/can't open/run. You click on the desktop icon and after a few seconds the PC freezes, the mouse still moves but won't respond when you click on anything and the keyboard doesn't respond. Only way to end it is to shut the PC down at the power.
So far it's done/doing it with the following 3 programs
Microsoft Conquerers (game)
Microsoft Age of Empires (game)
Lexmark Productivity Studio (application for my 3 in 1 printer)
The daft thing is they all worked fine on my old pc which died earlier this year as I messed up installing more RAM in it!!
Any ideas what might be causing this please?
