Multi-colored lines cross-hatch screen when booting up?

old age and damn bad cold has caused me to re-post the question below. Want to delete it, but don't see how.

This has happened ocassionally: When first booting my Gateway desktop (DX-4720-03, running W7 HP 64-bit with a Samsung 193P monitor), vertical and horizontal cross-hatching lines (many line of different colors) would appear on the monitor...and nothing else. I would then manually turn the computer off and re-boot. On re-booting, the black and white screen gives me various choices on how to open, I choose "open normally," and all is well. Other than that, I have had no problems with the computer or monitor's functioning. Any ideas? If this is the wrong forum for this question, please redirect.

Sounds like your video is going out, might want to replace the Motherboard if it is integrated video, or get a graphics card if you have an APG/PCI-E graphics card slot so you could avoid replacing the Motherboard.

Integrated graphics chips cannot be replaced due to them being built into the Motherboard, if you want to continue using integrated, then you will need to replace the Motherboard.
If the computer is under a warranty then you should be able to get a replacement by sending it in, but if it is not under warranty or you don't want to send it in get a PCI-E x16 graphics card since they are replaceable.

Computer not under warranty, won't be replacing motherboard. Sound like getting a PCI-E card would be the way to go. However, could you bear with me on few more quetions?

Does the card go into an external slot, or into a slot inside the computer? EDIT: Thanks, James, and I also just saw (Googled) that there is an expansion slot for a PCI-e x16 card. OK that certainly will make life easy.

Will I have to disable Nvidia?

What would be a good card that will at least give me the functionality, or even a little better, than the Nvidia?

Either way, after installation, is there a lot to do to get it working? Obviously, I know very little about this aspect of computers. Thanks for your help.

The slot for the PCI-Express slot is inside the computer, upon opening the case the slot would be at the bottom were you would see multiple expansion slots, the PCI-Express slot is usually blue or black in color.

I have never installed a card myself, but I believe it might have to be disabled in BIOS.

These two seem budget-fitting and should work with you well, and don't worry about it being worse than the integrated, a PCI-Express video card is 99.9% better than integrated:
Newegg.com - ZOTAC ZT-72SEG7N-HSL GeForce 7200GS 256MB (512MB TurboCache) 64-bit GDDR2 PCI Express x16 HDCP Ready Video Card
Newegg.com - Galaxy 84GFE6DC2EMM GeForce 8400 GS 512MB 64-bit DDR2 PCI Express x16 HDCP Ready Low Profile Ready Video Card

It usually requires just popping in the CD for the drivers and following the instructions to get it working, they aren't usually much of a hassle.

I couldn't find any documentation regarding the bios, but generally, you will see an item (generally in the 'peripherals' section) called 'Onboard Graphics' or something similar ( you could contact Gateway or ask in a Gateway forum for bios help if necessary). The following are the steps one might follow in a given circumstance:

1) In Windows Device Manager, find the Display device. Right click and choose uninstall (all as per screen shot)
2) Shut down your machine, unplug the power, open the case.
3) Making sure that you are grounded against the case with bare arm or hand (devices are sensitive to static electricity), insert the new card
4) connect monitor to back of new card, plug machine back in, turn on, boot into bios (often the Del or F2 key)
5) Look for bios item (as per first paragraph)
6) Disable Onboard graphics
7) save & exit
8) Allow machine to boot into windows.

Chances are that windows will have a driver for it, although it may not be the best choice...I use ATI's drivers. You should DL the latest 64 bit driver from Nvidia (since your specs state that you are running 64 bit). Point windows to the driver (or use windows driver if you prefer). That should do it.

Post back if you have problems or further questions.

Good luck,
James

Edit: It might be worth mentioning that the PCI-E slot will likely have a rentention clip (usually plastic), which you should take note of and position accordingly.
