I have a very strange issue that I thought may be due to bad RAM but after extensive testing seems to be something else... but I have nowhere else to turn so I thought I'd ask the experts here: A user reported that their PC would randomly go from normal operation to a garbled screen like this:

So I ran MemTest and I found a faulty RAM module. However, during MemTest, the screen ended up looking like this:

So, I replaced the memory and reran the test... the memory passes, but the screen still ends up looking like above (minus the red line)!! I ended up replacing almost every single part to test and the problem still exists. Does anyone have any idea what is going on?
Here are the relevant specifics:
GIGABYTE GA-B75M-D3H [replaced with spare & retested - same result]
Intel Core i5-3470 Ivy Bridge 3.2GHz [not replaced]
PNY Optima 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1333 [replaced with spare & retested - same result except no mem fault]
Thermaltake 600W [replaced with diff ps & retested - same result]
Any help is appreciated.
Thank you
Sunil
