I wasn't sure where to put this because it doesn't really apply to just my OS, and my computer is custom.

Okay, I've had my computer since about August, and it's done this a few times, but this really is not fixing. It seems like the computer is running fine, but the screen is all scratchy.. kinda like it's artifacting. It's really hard to explain so I took some pics with my phone.

It was working fine just yesterday, but I had to move out of my dorm and back to my house, and all the sudden... boom, its doing this. I usually just fiddle with the power management in the BIOS, and change some stuff around, maybe switch the plugs in my GPU and hope for the best, and that usually seems to work! But this time... not so much.

Here are some pics of what happens during bootup, and it's very very odd..

1. EVGA Logo on initial boot:

2. In the BIOS (tons of 0's or something...):

3. Still in boot stage, but gets to the point where it says "BOOT MNGR cannot be found" or whatever, but I just reinstalled vista:

My specs are:
EVGA 790i Ultra
4Gb Patriot DDR3

ANY Help would be extremely appreciated, so please please put in your 2 cents. I'm thinking about flashing the BIOS, but I'm not sure how. I've already done all the "reset to default" nonsense, but I really just don't know what to do anymore.

Thank you SO much for your help, and Happy Holidays!

Normally that happens when you have either overclocked your g-card too far or you g-card is overheating or both. I would try and find a different g-card maybe barrow one for a minute and see if you have that problem at least for pic # 1.

For the Bios picks seems like there are some errors. Did you do a bios update yet? I would search yahoo or google for say "Evga 790i problems" or something alog those lines to see if anything comes up. Maybe other people have had the same problem with this mobo but seeing all those 000000000 i would say the bios is bad.

You said you moved it. The first thing to try would be to re-seat the video card if you haven't done that already

I have not overclocked the GPU at all, and it shouldn't be over heating, my case temps never peak over 27 or 28.

I actually tried reseating it, and it worked to get that type of screen off, but then it froze when I was loading Vista, so I rebooted, and it's doing it again! UGH!

And I've installed the new 790i Ultra BIOS, but the bios looks like that every time I get the scrambled screen, so I think that's just going along with it.

Any more info would be greatly appreciated :thumbsup:

How clean is the stuff inside your case? Is it really dusty? I would think not, since the specs make it seem like a quite recent build.

Cleaning helps with some things, even though it might not solve the problem. Moving it could have knocked some dust free.

Can you get an old BIOS and try that? Did you install anything before moving it?

What about completely removing your graphics card? can you connect to onboard video and seeing if the problem is through your card?

Is it possible that the move out of the dorm could have damaged either the motherboard or graphics card? Remember that if you revert back to an older BIOS, you may have issues with Windows. You could try using a different GPU or on-board graphics, if you have any, to see if it is the card or mobo that is causing the problem. If one is damaged, you may be able to RMA the card back to eVGA.
