Very weird problems with NF4 Ultra D

[Ge&#124atinousFury]

Hey everyone, my system has been running fine for months up until a few days ago. I started having random restarts, lockups, and BSOD physical dump screens very frequently (as in once every 20 minutes). Sometimes even the BIOS locks up. I get the BSOD physical dump screen/restart the most though.

 

My BIOS settings are exactly as perscribed in this thread with the only difference being I'm running my memory at 3v instead of 2.9v.

 

My finger immediately was drawn to pointing at my Mushkin BH-5 as the culprit but I've managed to run it for hours (both sticks, then just stick #1, then just stick #2) with no errors in Memtest86.

 

I've also covered the following bases:

1. Read on misc. forums that ATI Catalysts have given a few users restarts/physical dumps. Uninstalled those, installed Omega Drivers. Problems persisted.

2. I don't have the Nvidia IDE driver installed.

3. I took my memory out of the orange slots (2 and 4) and put them in the yellow slots (1 and 3). Problems persisted. They're back in the orange slots now.

4. All my voltages/temps are fine and dandy.

5. Tried running with just 1 stick of memory (did that for each stick). Problems persisted.

6. My roomate's computer runs fine with my Mushkin BH-5 in it.

7. I've made no hardware changes prior to all these problems starting.

8. All connections/plugs are fine.

9. Nothing is overclocked.

 

And now to top it all off.....this is the icing on the cake:

 

Right around when these problems showed up, my computer restarted itself one day. I noticed that when it rebooted, the video was messed up. What once covered 100% of my screen now only covers the bottom 70% of it. The initial boot up screen, the BIOS, the windows loading screen, the windows shutting down screen......EVERYTHING not covered by ATI/Omega drivers once WinXP is loaded has been squished to 70% of it's original height. Once WindowsXP loads up and the ATI/Omega drivers kick in, the screen reverts back to normal where my screen is actually as big as it's supposed to be. As soon as I'm out of WinXP though, sure enough the top 30% of my screen is forever black. I'm completely stumped...

 

I've tried clearing the CMOS multiple times and I've flashed to the 510-2 BIOS but my screen is still "squished" as long as ATI/Omega video drivers aren't loaded. This is a very very annoying problem.

 

ANY help would be appreciated...thanks in advance.

try your roommate's vid card if his is PCI-E...if not try a PCI card or other PCI-E card if you can to test the vid card for problems.

 

if you try that and vid cards give you same problems, or you don't have one to test, just RMA the board to us and that will eliminate the board from the equation at least
