Cant start computer

Hello,
I cannot get the computer to start. to boot. It turn on for 3-4 seconds fan starts then al quits. I have replaced the power unit thinking that was it ,, no go. I have replaced the memory no go any thoughts? I pushe the sart button and only runs for 3-4 seconds doesnt even get to a screen please advise

Thanks B

perhaps your bios is corrupted try setting clear cmos on the motherboard or pulling the battery from the motherboard for about 20 seconds might help to reset bios settings too.

power supply seems dead

yeah it would

been there done that with dying psu's

thats actually very characteristic of a dying psu

Big difference between dieing and dead...

In my original post i realized lots of spelling issues but dang I was so frustrated. With that said the system config it this

brand Emachine. T5234 (yes quit laughing) but its all we have right now.
AMD 64X2 4000+ (dual core)
2.1 ghZ 2x512KB L2 cache, 2000MhZ BUS

NVIDIA GeForce 6150SE
2GB ram DDR
Running XP

As advised -I pulled the cmos batters and reset the jumper, its started and ran and as it was loading the monitor stated no signal and went blank at about the same time the system shut down again So again I ask any more thoughts besides the one I keep hearing (get a new machine)

if it boots the fans and not the system its dead for all intents and purposes DERRR what belle is going through I have gone through several times and it was a dead psu, by dead i mean wont boot the system dead. what do i need cartoon colored pictures ?

it amazing how you guys are so intent on having her run around doing all of this garbage for a classic symptom of a dead psu, wont boot the system =dead

pff
yeah do that it would be easier than telling you to test the power supply.

eww well hdd's can do similar things but you may have a faulty mobo. also psu's can ship bad so id test it anyway. if you try ram booting you test one stick at a time if you only have one stick you need 2. If the bios is corrupted its a dead mobo.

P.d. make sure the motherboard capacitors near the cpu socket have no leaks.



well finally it seems to be the motherboard ,fortunatelly i researched your pc's stock motherboard and its just like this one:

for 50 $ usd can't go wrong..

I had same problem. SAME.
I did alllllll the throubleshooting possible and nothing. In the end it was a faulty motherboard. So if you got warranty then send it in.
Same as you the PSU was my first thought.

Well glad you could at least turn it on.....

hmmm...... i cant think what would be causing to not be able to delete Firefox. Sounds like an OS issue.

Although for getting into bios, When it's posting, does it say press F2 to get into bios?
Depending on the Bios/motherboard it can be a different button, like my gigabyte motherboard. i have to press the Delete button to get into bios While F2 deals with the dual boot stuff.

Internet, well there maybe a setting in bios not turned on if your using the integrated ethernet.

i always press delete on boot to enter bios

I found it, yes its the delete key. the router is linksys with a WAp key that I had to rest on the computer still dont know why cant get out to the internet

you may need to boot in safe mode and uninstall the old mobo drivers and then load the new ones. if you are using xp then id leave the hdd or chipset drivers and then uninstall them after the new drivers are in as there is a chance that if youre using an sata they may ned the drivers to recognze the hdd.

or that not that its a requirement but it is best to start fresh. assuming you can afford to wipe the disk. Its not necessary its just best policy.
