My PC was connected to a Sony LCD for over a year without resolution issues. Yesterday, it suddenly restarted and the resolution changed to 800x600. I tried to change it back to 1600x1200, but the screen shows a warning 'Unsupported signal, please check the device output.' I checked all connections and outputs, and everything works fine except the resolution. What happened and how can I fix it?

I am using a monthly sales spreadsheet formula that calculates daily units, customers, $ sales, and the average $ per sale. I have included a week ending total row with the same formula, but it is now adding the week end total to the month to date total at the bottom of the page. How do I change the month to date total so that it excludes the week ending totals?

I have just opened Outlook Express 6 and my system crashed, causing me to lose all emails received from my inbox from late 2009 to yesterday. Everything else appears to still be intact. Is there any way I can retrieve the missing emails?

I bought an IBM NetVista PC on eBay, but when I tried to boot it up, the fan comes on, the green light on the front lights up, and the CD-ROM tray opens. However, when I try to boot from CD, it blinks 8 times with no beeps, and nothing shows on the monitor. I tried different monitors and confirmed they work with other computers, but with this PC, the monitor only shows a blinking yellow or orange light. Can you help?
