I have two issues:
1) Since the first boot, when i was loading Windows, there was some instability on the screen. There can be seen horizontal lines running down it, sometimes it's very subtle, but there are times when it gets worse. I experimented with refresh rates, it's set at 1024x768@85Hz, my monitor maximum. if I get the refresh rate lower the problem worsens too.
I did some troubleshooting:
-Updated graphics driver.
-Tested the monitor on my old PC (old Semprom 32 bits with an AGP card), no issues. Same VGA cable.
-Tested on another CRT monitor, the same thing happens; same monitor on old PC no issues. Same VGA cable.
-Made sure there is nothing close to the monitor or CPU that could be causing interference, CPU and monitor away from each other and no other electric artifact close.
-Latest Bios version.
-All things are connected directly to the wall outlet, no stabilizers or UPS.
The problem now is getting worse, sometimes the lines are more visible, and suddenly big wide lines run down and then stop.
I use that board with a sandy bridge cpu. You will have to weigh the cost difference when changing boards versus getting a low end card, such as my 210 nvidia chipset card with fanless heatsink. I found this one for 27 cents after rebate at frys earlier this year. Frys will probably have a similar deal on black friday. I've had no issues with my low end card at 1920 x 1080. For another inexpensive board, check out the B75 chipset boards, which have native ivy bridge support.
Sure. The z77 works well and has native ivy bridge support, but check the bios files anyway under "cpu support". Asus issues alot of bios updates, but if the board runs well after you install your cpu, I wouldn't flash it.
Neither, unless you live where prices are high. The 6670 shouldn't cost as much as the asus board. I would borrow another video card to see how the old board runs first; it may give you the same issues you have now. Your problem may be with the monitor. Why are using an old crt when led's are getting so cheap?
Actually I live in Argentina, most technology related things are not so cheap here, the thing is, for now, i don't really mind about this CRT. I figured out that it SHOULD work anyway, isn't that right? I'm afraid the guys at the store might say something like "The problem is you are using and old monitor, this new PC's are built for new LCD/LED monitors"
Best advice is to let windows 7 select the monitor settings for you. 85 hertz is too high for most monitors. Windows will often run at 75 by default. See if your issues go away at 75 htz. If your issues are the same at 75 htz, then the issue is probably the monitor, and not the motherboard. And your voltages are fine; some variance is normal.
