I’ve noticed a weird problem on a clean Vista 64 SP1 install. It first happened when I was using Picasa. I selected some photos and then hit “e-mail,” but Outlook 2007 never popped up. I first thought it was just a Picasa problem, so I ignored it.

I then tried right-clicking a small file, choosing Send To, Mail Recipient, and again Outlook 2007 didn’t open. As I understand it, the program should have opened a new message with the attachment.

Do you have any idea what could be going on?

I built my computer about a month ago—it’s nothing special. I’m running an Intel Pentium D 820 on an Asus P5W DH Deluxe motherboard. For a videocard, I’m rocking a BFG 9800 GTX.

I stumbled upon the System Information at the bottom-left corner of the Nvidia Control Panel recently. When I clicked it, I took note of the plethora of information on the 9800 GTX. What caught my eye was the very last line: BUS: PCI Express x4. That seems off, given that my card uses an x16 interface. What gives?

My Tagan TG900-U96 Turbojet 900-watt PSU recently burned out. I returned it, but it was no longer being supported through the third-party vendor I got it from. The vendor sent me an Apevia Warlock 900-watt PSU to replace my Tagan. I swapped it out, but now when I turn on the computer it won’t boot all the way. I get power lights, and the keyboard and mouse light up, but the monitor never kicks on, nor do the other connected peripherals (external Zip drive, printer, and scanner).
What could be going wrong with my computer? I never had this happen with the Tagan. Could something have been corrupted when the original PSU died?

I finally took the plunge and built my own rig. Everything worked fine until I plugged my Boston Acoustic Digital BA735 speakers into my EVGA 680i motherboard’s onboard outputs: Nothing happened. I received no sound at all. I tried the same speakers with a Creative Sound Blaster X-Fi XtremeGamer card and got the same result: zilch. Am I missing something here?
