Question about E-Machines T2792 PC Desktop

1 Answer

Power Problem I have not used my computer in about 3 months. It has been untouched for that time (the room door closed, no kids, etc). When I attempted to get on the computer, there was no power to the tower. I double checked the cords, they are in the right place, plugged in tightly, etc. Tried different outlets and different power cord. Monitor and perifpherals all have power. What could it be ??

Re: Power Problem

It sounds to me like your power unit inside the tower smoked. If you have the time and patience, replacing the power unit isn't to difficult to accomplish. You need to go to your computers manufacture online and download instructions via e-mail. There might have been a power overload that caused it to go. You can also remove all connections and take the whole tower to a repair shop to be tested. Usually $25.00 or less to verify problem. Hope it works.

My HP DC 5800 PC, Shut down unexpectedly. It is not happen regulerly. Some times it happen twice a day and some times it happen once a month. My operating system is Vista business.

Most unexpected shut downs like this are caused by over heating. Is the computer in a closed in space? If so try moving it to where it has plenty of room to breath. If this does not help I would suggest trying to replace the current fans to be sure that they are in working order.

How to tell if a motherboard is toast?

May be a fault on the connection with the surge. Connector leakage might be. And of course the power unit it might be. One or both as I feel made the trouble. There are various methods to test mother boards. Most simple method is to check each and every component on the board using a separate motherboard or using component testers.

Need to bypass the password to access windows...friends kid put password in and does not know what it is


You need to shut it down and remove the power cord. Press and hold the power ON button for about 5 seconds.

Open the case to the computer and do one of 2 things:

1) Pop out the CMOS battery which is about the size of a quarter and is usually a 3 volt battery. Leave it out for several minutes, then reinsert it in the slot. Close the case and connect the power cord. Power up and then you will have to enter the BIOS, verify your settings and do a Save and Exit. This will eliminate the password prompt. (Note:Different computers use different keys to get into the BIOS. It is usually an F key or the Delete key. Watch for the message as it boots.)


2) Most motherboards have a jumper labeled CLR or RESET. There are 3 pins together with a jumper on 2 of the pins. If the jumper is on pins 1 and 2, remove it and place it on pins 2 and 3 for 15 seconds. Then remove it and place it back on pins 1 and 2. Replace the cover, power up and again, enter the BIOS and verify your settings and do a Save and Exit.

Thanks for using Fixya.

HELP - I have an Acomdata External Hard Drive (I think 160GB). Have used it sucessfully 1x month for all of my kids pictures (about 100GB) for the past year. Just tried to use it with the same power...

Try a different power supply. Also check cables from the Ext. Hard Drive to the computer. If none of that helps and you know how, open the Ext. Hard Drive case and remove the Hard Drive from the case. Connect the Hard Drive to the appropriate BUS and power source inside the computer. You may have to adjust the jumpers, probably to a slave setting. If it still doesn't work then the Hard Drive may be toast. This is the reason I always back up important files onto two different devices. If one fails the info is still on the other one. That is all I can think of right now. Hope you get your kid's picts back.

My mac won't recognize linksys router.

It sounds to me that u are using windows_vista ?? Vista has to have its OWN o/s software\programs made specially for it!
TRYOUT::turn off all virus scanning software,firewalls,etc,etc, EVERYTHING that loads automatically .One way is to wait after u turn on the computer.wait!, wait!, then close everything that sits on the bottom of the right screen.Connect your Linksys so that your o/s sees it., Load the drivers AFTER that, then see what happens.
TRYOUT 2:: goto [start]bottom left of screen (no!, the other left!!)ONLY KIDDING! [run] msconfig,select "secective startup", UNcheck everything that looks like it is protecting your computer.[reboot] then follow TRYOUT_1
GOOD LUCK, jardy
