Every time I log on or switch to E-mail or other programs my resolution changes from highest down to 640 x 480. Can somebody help?

Hi kthorei,

I would like to suggest you reboot your computer in a Clean Boot state, below are the instructions. It's possible a program or driver is causing this issue. To help troubleshoot error messages and other issues, you can start Windows 7 by using a minimal set of drivers and startup programs. This kind of startup is known as a "clean boot." A clean boot helps eliminate software conflicts.

How-to run Windows in Selective Startup (Clean Boot)…​

1.Click Start, click Control Panel, click System and Maintenance, click Administrative Tools, and then double-click System Configuration.​

2.Click Continue, or provide Administrator credentials if prompted.​

3.Click the General tab, and click Selective startup.​

4.Under Selective startup uncheck Load startup items.​

5.Click the Services tab, check the Hide all Microsoft services box, and then click Disable all.​

6.Click the Apply, then OK, and then Restart.​

Update the bios.

Go to the HP site and fetch the latest Win 7 drivers for your model.
