Hello,
Any and all advice appreciated folks-have just tried to upgrade my Dell XPS 720 H2C memory from 2gb (4x512 pc2 5300) to 4Gb (2x2Gb pc2 8500)
Initial first boot seemed fine, detected change in memory on boot and booted into windows okay and it started looking to install drivers as I may have replaced some of the USB devices at rear in different slots....no bigge,right?
Anyway all was fine, keyboard and mouse working and able to launch browser then BOOM....in other words very quick flash of the BSOD and power down.
Powered up again and into windows okay but now no mouse or keyboard functions!
Steps taken so far....have jumper cleared NVRAM, have reset BIOS to factory, have tried memory in different slots (3&4 instead or 1&2) and all with same results but here's the kicker....have removed memory and put my original back in and SAME THING, no mouse or keyboard functionality, I have tried 2 different mice to be sure and tried then in another system and they work....keyboard works fine in BIOS/set up menus just nothing in Windows....assuming all USB functionality gone in windows as cannot test any other devices without the keyboard or mouse....oh, same thing in SAFE mode as well.
System running Vista premium 32 bit.
Any and all help greatly appreciated as I need the system up and running ASAP as run a small business and completely lost without it!!!
