HOW RE STORE T5274 TO FACTORY SETTING - eMachines T5274 Desktop PC

You should be able to upgrade to Windows 7 with little problem. I've done it on a few different laptops.

Have you installed a wireless card? It likely doesn't have one. Most desktops don't come with one.

My A2 effect not work properly

When looking at the motherboard with the back of the computer to your left, there should be a row of pins on the lower right corner of the motheboard (or close to the corner). These pins are normally marked as something like PLED (for the power LED), PWR SW for power switch, RST for reset, IDE LED for the hard drive light, etc.
The power switch is normally along the bottom row and the power LED is on the top. But--to find where the power switch goes, take a small screwdriver and short two of the pins to see if the computer turns on. If it does, you've found the power switch. When the computer is running, put the power LED plug across two pins to see if the power light lights. If it doesn't, try two more until you find it.
var fctb_tool=null; function FCTB_Init_88a0199091e74aa0ab8dd27b901b03c6(t) { fctb_tool=t; start(fctb_tool); }

Seems a BOOT failure. Try eMachines Support: Support Documents

It sounds like you may be trying to load a lot of temp files.
Go to CNet.com download Advanced Systems Care "Free Edition"
Follow the directions to clean up your system.
If that does not fix the problem Download a copy of Glary Registry Repair (also free) and run that.
These are two of the best software packages to have.
I have been useing them both for a long time,and have tried others, but these two are far and away the best I have found- and they are free!

It does not have a TV-out function as it comes from E-Machines, but it does have an open PCI-X expansion slot, so you could buy a video card with TV-out if you wanted to add that feature.
