SOURCE: Gateway Intel 850 Motherboard will not boot

Please download a memory (RAM) testing program for free. Click the link. http://www.memtest.org/
This program will allow you to make either a bootable floppy disk or a bootable CD. Before you can use the above program I will need the correct model No# for the Gateway, found on a sticker somewhere in the PC case along with the serial number.
The information regarding you're board is incorrect. You can find the boards model number written in white lettering somewhere on the board or on the side of a PCI slot.
The link for the Intel 850 is listed here.

Gatway's link here.

I'll check back from time to time & check if you have found the correct information.

Good Luck

SOURCE: Adding Memory to Gateway 420r

If you mean a Gateway 420GR (there's no "420R" listed on their site), then you can have up to 4GB of RAM and you can use 1GB modules. Here's a link to the specs page on their site:
