Hello Friends! I have a computer with Pentium II 400 Mhz Prosessor, Intel 810 Chipset Motherboard with a HP Lazerjet 1010 connected via a USB cable. Everything was fine before I changed my RAM from 128+64 MB to 128+32 MB. After changing the RAM, the computer started smoothly but all of a sudden crashed and restarted automatically. Since then I am having a problem with my printer. Evertime I try to print, it gives an error called "User Interface Required". When I checked the Device Manager, I found another problem. Under the System Devices category there is something called "CP2101 USB to UART Bridge Controller Art Registry Bus" which has a problem saying "The device is not working properly because Windows cannot find the file (slabvcr.vxd) that loads the driver from the device ( Code 8 ). I tried to find the file in both the Motherboard driver CD and the Printer driver CD, but found none. So at last, I ran the Windows Setup again but all in vain. I even removed the newly installed RAM with the old one, but still no help. Is there anyone who can help me to come out of this problem. I shall be really obliged.
