Arif installed Vista on his previously XP based system and now the rear (PCI) sound card doesn’t work but the front (integrated) one does. The obvious problem is that your rear sound card needs new Vista drivers. Vista drivers may be available by default for your onboard sound card but not all additional PCI sound cards will be supported by default. You will need to find out the manufacturer of your rear sound card and download the latest Vista drivers from their support section if they even have any.
Jamie’s XP system is crashing after a RAM installation. I would say the obvious thing to do is remove the extra RAM you installed and see if the situation rectifies itself. If not, try to remember if you changed or installed anything else and undo that too. A system Restore is another option. The RAM you bought may be faulty or incompatible with your system or you may have a RAM mismatch. Also check the RAM is installed properly.
Amit is finding that GTA 4 runs fairly slowly on his pretty high spec PC and wonders if a RAM upgrade might help. Amit, my best advice if you’re playing games on a PC is to max out the RAM and get as much as you can. You can input your PC model in the ‘Memory Advisor” tool at www.crucial.com and it will tell you the type and max amount of RAM you can put in your PC. I’d also recommend you get the best graphic card you can too. Don’t forget the CPU can also be upgraded.
Varun can’t seem to install Windows XP. I would say maybe the hard drive is faulty so see if you can install on another one. Could be a faulty hard drive IDE cable too. Also, if you have more than one partition , try merging and installing onto a single partition C: drive. If you are installing over an existing operating system or upgrading, your Anti Virus software might cause problems.
Sanjeet is seeing a 6 way screen split and flickering on his monitor (below). I’ve had this before with my own monitors and it turned out to be a faulty video/graphics card which I had to replace. You could try refitting the card or maybe updating the drivers.
