System Crashing / Blue Screen after 8GB RAM Installation.

I just built a new system and installed Windows 7 Professional. Originally with 4GB of RAM, running very smoothly.

I just installed 4GB more and the Windows will either crash into a Blue Screen in the middle of starting up or randomly crash without notice after a few minutes running.

Any reasonable explanation?

System specs:


4x2GB Corsair RAM

Corsair 750 watt power supply

1TG Hitachi Hard Drive

PNY Nvidia Quadro FX580 Video Card.

I appreciate any help. Thank you, Arturo.

Do you have the blue screen details, or can you upload the crash dumps to SkyDrive?  It may be that the memory is bad - consider testing it with Windows Memory Diagnostic or memtest86. Try removing the original RAM modules and running with only the new ones.  Do you still get the blue screens?

Are you using the latest BIOS available?
