I have a gateway gt4022 at first i had the power issue but after sometime it solved itself out i guess......but after that i started getting another problem which after the PC boots into windows.....the screen goes fuzzy.......please i need help.......cpu amd athlon 64 3700, 1.5 gb ram, 200gb hdd

Probably hardware failure. To test that remove all disks and extra components and try again to boot into BIOS. If you can't then you will know for sure. If you can then take the opportunity to change the boot order and put the cd first and the hd second. Now connect an optical unit and try to boot in a bootable disk, preferably a Linux Live-CD. If you can then the hard disk is dead, replace it.

Try a different monitor (borrow one). If that doesn't work, you need to take it to the shop.

Power supplies shut off automatically when one of the voltage wires is shorted to ground somewhere. This is why you see the fan kick over for a second and quit. This is probably a bad motherboard.

Well, I think gateway is just a computer manufacturer, so if you are still under warranty, you could possibly get a replacement. But before doing anything, and if you are comfortable with doing so, open up the side of the casing, and take a look around, see if any cables seem unconnected.

If the power went out while it was on it may have been given a surge. If that is the case the motherboard is going to need to be replaced. Check the power supply connection on the motherboard if it is discolored then that is the problem.

if your motherboard is getting power .try changing the boot sequence

i got a gateway computer too. And i got the same problem with u guys before from 2 reason.....
- first was when i messing inside my computer ( i dont really know maybe something get unplug), and how i fix it was touching everything inside my computer hehe make sure everything is pluged in
- second was i was trying to overclocking my computer and bam is shut down, i turn it on again, the fan keep running faster than normal and not slowing down hehe screen doesnt turn on either. how i fix it was unplug the power of ur computer, hit the power buttom couple to let the the power in ur computer run out, plug the power back in and problems fixed. Good luck

Hello,

Open your system and fix any cable inside the system, maybe gor a loss connection. i guess that hard drive not detected. so fix it. please tell me what happen next i will surely give you more solution in it.

Looks like your motherboard is actually pretty good. What do you need to replace it for?

Here's a good website: http://www.tigerdirect.com/
Click motherboards or motherboards with cpu included.
Another website, http://reviews.cnet.com/4566-3049_7-0.html?tag=dir gives you a list of motherboards and where to buy them.
Usually, motherboards under $100 are old or cheap.

If you need an exact copy of the one in your GT4022
this is your motherboard on gateway.com: http://support.gateway.com/s/MOTHERBD/FIC/4006105R/4006105Rnv.shtml
just google that motherboard and you should be able to find an exact copy to buy.
