    Hello Ikanate, Is your Power Supply fan spinning? Is this a brand new computer? Were you able to use your computer before? How many times has this happened? What's your operating system? What are the specs of your computer? I'm sorry I need to ask these questions so I can pinpoint what's exactly causing your concern to happen. Thanks! Cheers, Art Pena

Very noisy fan on a Zenith 50" Plasma (Model 50PC3DB-UE). Should I replace the power supply or just a fan?

if it has only one fan, replace that but look to see if fan dusty or not.

I have seen ones with two identical fans and one made noise and the other did not, swapped them and then knew for sure which was the bad one, in that case better to replace both fans at same time.

Computer won't turn on

try removing the battery and then plugging the laptop in. when you plug it in make sure that the light comes on that shows you the laptop is charging. If it doesn't wiggle the power chord inside the laptop till it does light up. Then press and hold the power button. With these Toshiba Ive seen that you may have to press pretty firmly. Hope this helps :)

My gateway laptop will not turn on when you push power button.

If you power it on and get the light it means either two things:

1. It needs a minimal charge on the battery to power. ( havent seen this since the old Compaq/Apple stuff ) or

2. The motherboard is fried. ( Just diagnosed a HPDV6000r special edition with this beautiful computer, dead motherboard ).

What is the warranty like:

NOTE TO ALL STUDENTS: Buy New laptops in November, so the warranty comes up in October, after you know you need more computer or repairs!

Emachine T3624 will not power up

Emachines are notorious for having faulty power supplies. If your lucky you just need to replace the power supply. I've seen a lot of them where the power supply also fried the motherboard.

Ballast or color wheel next?

The color wheel will normally spin-up even for a brief moment when the set is powered up. I have not seen a color wheel go out with a lamp. I have seen a ballast go bad with a lamp. I would replace the ballast first. You did not state wheather the color wheel was noisy or not. On the Samsung DLP, the color wheel is normally very noisy before it is gone. I hope this will help you.

Hard drive became noisy and now is not recognized

I am sorry to tell you that noisy mean's your media disk was damage. It is no longer usable but there is a way of recovery but I will not assure. Just try to used magnetic coil from 150-300 Watts sound box then place it on the top of the harddrive within 12 hours then remove it.

But the problem still the same it is possible your hardrive absolutely damage.

Please rate me as solved if my solution is helpful.
