There was recently a lightning storm and it burned something out on my desktop computer. I thought it was the power supply, so i bought a new one. I installed it, and when i turn it on, the hard drive led light comes on on the front of the tower, and the fans spin, but the computer does not turn on. Can anyone help me fix this?

eMachines?

If this is an eMachines computer, this is a common symptom that the board is toast.
It's also a sign that the board is toast in most other brands as well :whistling:

Yep, in my experience this is how eMachines die because of the low quality power supplies they put in them that eventually send a big surge down the line and fry the motherboard. In your case the storm probably quickened what was due to happen anyway.

Recommended to replace the motherboard and the power supply. Whatever mainboard you go with it will be better than the one it came with.

Can you send me some links to some motherboards that would be compatible with this computer. It is an eMachines T2245.

The eMachines T2245 uses a Socket 478 board so therefore most Socket 478 boards will fit in the case that are called "microATX" boards. It also uses any standard decent (ie not Bestec :whistling:) power supply unit.

However since this machine came with a Celeron processor, while you can drop it into a new board it's not exactly going to set the world on fire performance wise whatever you use. The memory's slow, the processor's slow and the machine, in common with most eMachines of this generation, was basically probably the cheapest thing on the market at the time.

In my experience, you often find that the Windows installation is heavily damaged (which you only notice when you try to repair the installation which you would need to do with a Windows CD when you obtain a new board) and it won't repair. Then you have no choice but to wipe it. Then you sometimes find out the hard drive is dying anyway as its been shot by the Bestec power supply.

Unfortunately this is the reality of life with an eMachines computer. Cheap at the time, it lasts three years at best and then the power supply burns the rest of the components.

http://www.techspot....topic62782.html might be of interest on this issue as well just to prove I'm not making this up.

I have had this happen to 2 EMachines computers myself. The power supply will last not last long, seems like 2 or 3 years max. It doesnt seem to matter if it was hit by lightning or run over by a truck.

I ended up buying a new Gateway computer, and salvaging the hard drive before it would have been burned out too!

The power supplies are junk! Thats why you probably only paid $199 on Black Friday for it
