I have an emachine t5010 that wont turn on. i do have the green light in the back. when i try to turn it on however,the power button lights blue just as i press it but thats it. if i hold power, the fans run, the power light flashes and nothing else happens. do you know what may be causing this? (no recent hw changes. ram added 3 mos. ago)

check all the leads to the hard drive and check that the fan starts spinning when you switch it on if it dont start then the problem is the switch these do often go and can be easily replaced and they are not expensive i had the same problem and found that it was just the switch hope this solves your problem for you you can bypass the swith so that the computer comes on when you turn the plug on but when you shut down the computer this shuts everything down but the switches are cheap enough to buy if you have changed the power pack then the only thing it can be is switch .................................

Are the pins from the switch to the motherboard connected properly?

Could be a faulty switch on you case. T

ry shorting out the two power on pins (on motherboard) with a screw driver but be carefull not to touch anything else with it!! :)

hope this helps?

no just put the cd/dvd in the drive and follow the instruction

SOURCE: computer won't boot after adding ram

It could be one of the following:
1. You fried the motherboard when you replaced the RAM. This is the worst case scenario, but it does happen. In any case, don't replace your PC yet!
2. Your system was off too long, and the battery drained. This does actually happen, believe it or not. The battery stores the computer's BIOS setup information and if it drains (goes dead), the computer doesn't know what to do when you turn it on. The first signs of a draining battery are usually time being lost on the clock (slowing), or "C Drive" errors/warnings that come up but the system is still booting up all the way too. If you've had either of these happening before you added the RAM (and they're things you'd probably notice), then I'd suspect the battery.
3. You unknowingly knocked something loose when you were dealing with the RAM. I only did this once, because it took me FIVE HOURS to figure out. To fix this, be very careful and make sure you are GROUNDED. Don't touch anything on the motherboard that you don't have to, but for all plugs and other removable connectors, make sure they are snug. Do the same with all of the drives while you are in there.
3. The obvious question is: Did you purchase the correct RAM? I'm assuming you already verified this (if not, it could be the problem). If the RAM is ok, are you sure your motherboard can handle the addition? There's a limit to the amount of RAM any motherboard can recognize. Putting too much RAM in can confuse your computer.

There are other reasons, but I'd hafta vote for the battery. It just sounds like your computer is turning on and doesn't know what to do. If it is the battery, it's very simple to replace. You will find it on the motherboard - it looks like a watch battery on steroids (it's about the size of a penny or nickel). Take it out and take it to your friendly computer store. A new battery is about $8 or so.
