Emachines 2792 i have an emachines t-2792 and it keeps restarting itself before windows has a chance to load. it does the post fine and everything. i have tried a windows xp sp2 cd and it kept comming up with its missing files. then i tried the restore software that came with the computer and it seemed to take that but it still won't load windows. i get the xp simbol and then a flash of a blue screen and its restarts.

Reinstall windows and format the hard drive.

Please reboot pressing F8 to access safe mode. once there see below

You may be a victim of spyware/maleware infections. You will need to have your system cleaned. This should help resolve your issue.

I would recommend trying CCleaner first to see if this helps you. Please keep in mind this will not rid your system of everything just keep you a float and offer you a fighting chance.

Please keep me posted and updated on your issue. I am here for you and will see your issues out till resolved.

Have a great and wonderful day :)

There are many ways. Before windows 7 it might be more difficult but now this OS will not erase your hard disk so you can install it and it willcreata a windows.old folder with your old information and folder system will be intact.

If it reboots before you make the Windows load screen, chances are it's the power supply. You can go into the BIOS, look at the power setup and with most BIOS's you can watch the DC supplies. If they vary like mad while you're doing this (with the PC effectively in idle), either something is loading down the power supply or it's defective.

If it gets to the Windows startup screen and starts to load, then reboots, it's probably a defective RAM chip.

Restart your computer and as its starting hold F8. This will take you into system restore. Choose Factory Default Restore. This will take your computer back to its original state when it was purchased. You will lose all files that were previously in the unit.

there is usually a jumper with three pins beside the cmoss battery just move the jumper to the last two pins for 5 seconds and put it back that will reset your bios that may help

your computer is virus infeted.
when upower up the computer prerssF8 key then enter in safe mode.
then type "msconfig" in run then go to stratup it is last tab
then disable all stratup then restart your computer.
also if u have updated antivirus like avast scan your computer in safe mode.

You can manually download drivers from eMachine's site: http://www.emachines.com/support/product_support.html

The operating system, you'll need a disk...and product key.

Sounds like a reformat may be your only option at this point. How far will the machine boot up? Can you boot up in safe mode?

Did this problem just happen out of the blue? Were you using it and suddenly the PC just up and went belly-up? If so, it sounds like you may have bigger problems than merely a Windows problem. If you don't even see the eMachines logo at bootup before the Windows logo, then something more serious, like a motherboard issue, is your problem. Post back with more specifics, but if you don't see anything at all at booting, like any text or logo or anything, then at the very least the integrated ATI video isn't working. The solution then is either get it fixed with a new motherboard or buy a new one. As this particular model is >1 year old, it won't be under warranty, hence more expensive than it's worth.

On the other hand, did you make any hardware changes that you didn't mention? If so, post back with details.

If you are running XP, try starting in the Safe Mode. To access this, at AC power on, start tapping the F8 key; this should bring up a short text menu that gives you the Safe Mode option. If F8 doesn't work, try F5.
If you can get your desktop, open the Start menu, then All programs, then Accessories, then System Tools, then System restore.
If you have had your Restore feature turned on (it is by default) you chouls be offered the chance to restore your system to an earlier date. These will be shown on a calendar in bold if there are earlier backups available 
Choose a date a couple of days before your fuse blew. This restore routine does not lose any work of yours, but essentially checks and replaces corrupt system files and your settings before the roof fell in.
