    Should you put grease on top of processors then the fan or does it need it?silver grease.

Hi there.
Try clearing the cmos
Boot up - d015d7b.jpg<<<<< you will see in the picture a plastic jumper (in this case coloured green), move it to the other position and hit the on/off button, then put it back in its original position and power up the machine again. Hopefully the issue will have been sorted. If there is no jumper remove the battery for an hour and make sure the power cord is removed from the back before you clear the cmos

Good luck and thanks for using Fixya!!

    Yes its silver heat sync compound that goes on top of processors, this ensures that the heat is dispersed evenly

I put in my op sys. disk to reload operating system,its not reading the disk,tried pic cd, working foin .si its not the dvd/cd drive???

eMachines T5048?

Suggest you enter BIOS Setup, and in Boot Options, set the first boot device to CDROM.
This makes the computer boot from the Recovery disk.

How to enter BIOS Setup? (May be called CMOS Setup also, but I don't believe the computer is that old)

Look at the bottom of the monitor screen, as soon as the eMachines logo comes up. It will state what key to press to - enter BIOS Setup.

Usually it's the DELete key, or F2 key,. for eMachines. May be the Tab key.

Window of opportunity went by, and you didn't get into BIOS Setup?
S'okay. We just need to know what key to press, for now.

Got the key written down?
Open the optical drive, and put the Recovery disk in. Close the optical drive tray.
Now hold the Power On button in, and for a count of 10 seconds.
Turns the computer off.

WAIT 1 minute, turn the computer on.
AS SOON AS you press the Power On button, start tapping on the enter BIOS Setup key.
Tap in 2 second intervals.

Hear beeps? Ignore them. They are Stuck Key Error Code beeps, and it is you that is doing it.

Takes a few seconds. Now you should be looking at the BIOS Setup utility, and the Main menu.

BIOS Setup utilities change from computer to computer.
That's because there are 3(?) major BIOS manufacturing companies, and each BIOS has a different version.
(Phoenix/Award and AMI)

The menu headings may go across the top.
Just one example;
Main / Advanced / Power / Boot / Exit

Or they may be listed in a column,

(Scroll down a little)

When in the BIOS(CMOS) Setup utility, you CANNOT use the Mouse anymore. You have to use the Keyboard to navigate around.

With the menu's going across the top, for example; you would use the Right Arrow key, and highlight -> Boot
Then press the Enter key.

With menus that are in a column, use the Down Arrow key to highlight Advanced, or Advanced BIOS. (Or Advanced CMOS)
Press the Enter key.

You will see - First Boot Device, Second Boot Device, Third Boot Device, and Boot from other.
To the right you will see the various devices, the computer can boot from;
HarDDrive, (HDD-0), CDROM, Floppy, Internet, etc.

You want CDROM to be to the right of First Boot Device.
If the devices are just listed in an order, you want CDROM at the Top.

With First Boot Device, Second Boot Device, etc listed;
Use the Down Arrow, and highlight First Boot Device.
Press the Enter key.

Your cursor will now be in the device order list.
Use the Down Arrow key to highlight CDROM.
Now look at the navigation guide at the bottom.

To move CDROM to the Top, you may press the;

Page Up/Page Down key, or the +/- key. (Plus/Minus key)
Depends on what is listed in the navigation guide at bottom.

(If +/- key just press the - key)

With CDROM at the Top press the Enter key.
Things differ here too;

A small window may come up asking, Save Changes?
It may show F12 - Save Changes
Or it may show a Y for Yes, and an N for No
(Or Yes/No)

If F12 just press the F12 key, and the computer will restart.
If you have the Recovery disk in the optical drive, the computer will now boot from it.

If Yes/No, or Y/N; use the appropriate Arrow key, and highlight Y, or Yes.
(Note: If Y just press the lower case y. The uppercase Y is just shown for clarity)

Press the Enter key.
If the Recovery disk is in the optical drive, the computer will boot from it.

Recovery disk isn't in the optical drive? No sweat. Put it in there.
Now press the CTRL key, ALT key, and DElete key AT THE SAME TIME.
This makes the computer restart.

If you have never approached this procedure before, it probably looks like, "Wa-wa-wa".
(That's what my niece states when I try to explain computer technology. Wa-wa-wa from the Peanuts cartoon. lol!)

You pull up the BIOS Setup utility, and tell me what you see.
You'll be my eyes, and I'll step by step you through it.
We will post back, and forth in a Comment.

I just installed a new hard drive into my gateway desk top and put recovery cd in and its says missing operating system


You will need to go into the BIOS screen and set the first boot device to CDrom. You can get to BIOS when the machine first boots, as soon as you see writing on a black screen press the bottom to get to setup. When you get to the setup screen look for an option to set boot devices or "boot priority". The first boot device needs to be CDrom and the second device can be Hard Drive. Now save the settings. This time on boot the computer will boot to the CDrom restore disk and you can follow its guides to restore your system.

I hope this helps, if so please rate our solution.

I replaced the heatsink fan it booted up like three times.tryed put load xp wouldnt boot up from cd rom.Iset boot priority to cdrom.I tryed to reset jumper took out bat all night.the first time it booted...

Well, first you should check wether the fan actually starts when you turn on the pc. If it doesnt your cpu will be overheated in no-time, causing the pc to reboot. That fan then probably has the wrong voltage, or requires to much power, which your power supply may not be able to provide.

If it works, you should try to find out how powerful this fan is, meaning how much air it moves per minute. If this fan is less powerful than the previous one, your cpu will be overheated.

If neither of these solutions apply, I guess you should contact your vendor and request replacement. It may be just the fan that's broken.

Instantly shutdown

This sounds like it could be a heat issue. When you're in windows, you're using the processor more than if it just sits idle in BIOS. Using your cpu creates more heat. Make sure there is no dust in the fan or the heatsink on the cpu. Also, remove the heatsink and clean the old thermal grease compound off the heatsink and cpu and reapply fresh thermal grease.

Boot sequence problem

try booting to DOS screen only by inserting a boot-able floppy disc (I use Win ME disc at this point although my system is also Win XP). Then select "boot with CD-ROM driver". It will detect your CDROM drive and assign a letter. Now insert the CD and boot from there. I have done this sequence many times with no problems.

Your CPU may have a problem

Have you removed all memory, other cards and unhooked all other drives to see if a short exists there? With a 300W PS some other component may be pulling too much that the CPU can't start so it tells you the problem is with the CPU or The CPU its refering to is on the video card? Good Luck, Tim
