HI no startup beep on my emachine and no signal onscreen

The beep signifies an error. But different bioses have different beeps. You can check with the emachine site to tell you what 1 beep on the machine signifies and you can be guided accordingly. Could be bad power supply, connection, peripheral, etc

you should not leave PC on for more than a couple days.

It may have gone into Hibernate and if there is a bad sector, (i.e. read errors,) when that is loaded into RAM, then that can cause many symptoms. Try to boot into Safe Mode, then if that works, Restart and use Normal mode.

This could possibly be a driver issue. Please disconnect all devices connected to the computer other than the mouse, keyboard and monitor during installation. If installation completes successfully, then you may reconnect the devices.

Go to http://www.emachines.com/support/product_support.html?cat=Desktops&subcat=T Series&model=T6532 There you will find all specs and downloads for your machine. Then once you get the motherboard type you have you can go to tigerdirect to find motherboards.

Sounds like windows resolution or refresh rate is too high for the 15" monitor. Try starting in safe mode and setting the resolution below 1024 X 768 and refresh at 60. Restart.

Hi momawarbucks

Check if your secondary screen is attached by going to desktop and right click , then go to properties and advanced.

Also check if your refresh rate is on 60-70 Hz

And that the resolution your PC is on , is supported by your Projector - i.e. XGA Projector - 1024x768

Good luck and thanks for using Fixya !

Getting into Windows Safe Mode Start Windows Normally Reboot Return to OS Choices Menu
Good Luck, Should get ya back up and started .

Please dont for get to Vote.Thank You.

Bad capacitor(s) on the motherboard can cause this problem, corrupted BIOS maybe... try flashing BIOS.
Probably the CPU if your not getting any error code beeps on startup.. NO Processor for the BIOS instructions thus no Beeps !
