I recently built a new system, and it ran ok for several months but now it has all changed.

My system in specs are the Lanparty NF4 Ultra D board, 3700+ Sanny, 7800GT, 2gb pack of geil.

I have been getting a bsod over the weekend more than once, MACHINE_CHECK_EXCEPTION. Never encountered this before so did a bit of research and found out it could be a ram issue.

Booted into memtest86 did one pass, got to test #8 loads and loads of errors. So i decided to up my ram V's up from the defaults to 2.8. This stopped the errors on test 8 of memtest and it passed ok, so i thought the issue was resolved and reformated.

Run ok for a day then started getting same bsod and my pc would take forever loading up windows and never seem to get in. After 10+ restarts it would boot into windows. Now knowing that memtest 86 is never 100% accurate i swapped my mem over for my old matched pair of crucial ballistix. But it still had same problems. I decided to remove one of the modules of ram and just run in single channel for a while. When i did this my pc went straight into windows and it seems ok now.

I will prime it like this overnight in single channel to see if its stable. If it is stable im guessing its a memory controller error or something. The memory controller is on the chip in x64 chips right? If so should i be replacing the CPU or the motherboard?

Yes seems to be happening when its cold. I get into a cycle of windows not starting up reboot a few times, then get into windows and it usually bsods and falls over again. It seems to only happen when iv'e not been using the PC for hours.
