Hello all. I am in the process of building a SFF. Check out my thread in the SFF forum for the component details. However, I'm really getting frustrated with the problems I've run into and would appreciate some help.

I have just recently replaced some faulty RAM that was failing memtest before. Now, I cannot get any video at all. My graphics card was working fine yesterday, but now it won't even turn the monitor on from standby! I just reseated the gfx card, but to no avail. What the heck is going on here? I figured if it was the memory that was fracked, I would get all sorts of mobo beeps and a video display, but a memory error msg at boot!

Any ideas? Is there something I'm forgetting or do I have the world's worst luck that now my bloody gfx card has gone belly up.

Edit: Tried hooking it up via the onboard VGA too. No luck. Something is sour. The ram is brand new Gskill!

Edit2: Replaced the old RAM - system booted - with some error message about resetting CPU freq in CMOS. I went into the bios and changed the "overclock monitor" (Biostar Tforce 939 - thats where all the DRAM timings and important settings are) setting back to automatic, thinking that the previous 2-2-2-5 I had for the PC3200 that was in there before was the problem, then reinserted the Gskill. Black screen again. ARGH
 
Check the monitor itself. I once had the same problem as you. I thought it was the graphics card but it turned out to be the monitor.

Oh and can you test the graphics card in another PC?
 
I did test on a second monitor - same problem. However, when I switched back my old RAM, it booted just fine!

I guess I've narrowed it down to the ram itself, but what I need to know is if there is anything that could be causing this problem besides a bad stick?
 
Found the problem - for whatever reason the Biostar default settings for ram timings didn't work. I swapped out to old, damaged ram and manually set the timings to 3-4-4-8 T1. Then it booted. Ran memtest for 3 hours, 4 passes without problems.
