I am using a laptop using Win7 HomeBasic and a Remote Desktop connected to a PC using Win7 Ultimate. I can connect with no problem but I cannot access an external USB hard disk that I attach to the remote PC (the Win7 Ultimate PC). The USB HDD shows up in My Computer but when I double click it I get the message "F:/ is not accessible. Access Denied". The USB HDD works fine when I connect it directly to my laptop.

I would appreciate any advise to fix this problem. Thanks

Hi

I bought a PC with Asus motherboard which has also a built-in VGA and Sound card. It's been two years already since i been using the built VGA. then one day suddenly my PC got a black screen.

Thinking it was just some virus infected my pc  i reformat and install the important drivers like the VgA, chipset, sound, and others.  Then after finish installing everything and restart my PC and when i check my screen i notice that my VGA driver wasn't correctly installed   because my screen is still too much lag. So i decided to install the driver for VGA but i got some message

Previous Drivers Found

I use Windows XP. A few minute after startup, it gives me a message that say's, "update your computer".

Hi All,

I decided to upgrade my gaming laptop but due to budget constraints I need to choose one first as a priority. Should it be my RAM or graphics card that I should consider first? My RAM is 1 gig 800 MHZ and graphics card is nVidia 7200GS. Obviously, I just want to avoid lags while I play online games and at the same time, no freezing screen.
