BSOD After Sleep Mode

After putting my computer to sleep, upon waking I receive an error code, which should be present in the dump file. I closed the error window before copy pasting it in here. I will update the post with the error information next time it happens. This only happens when putting my computer to sleep. Hibernate and shutdown do not have this problem, and I have not received any BSOD's during use. This has been happening for about 10 days. My memory set up is kind of strange. I have 2x1GB 1.8V ram and 2x2GB 2.1V ram, both DDR2, and both running at 2.0V. I didn't want to overvolt the 1.8V ones too much. The timings are slightly loosened on the 2.1V ram to match those of the 1.8V ram. I have run Memtest86 with no errors. My hard drives have also checked out fine.I have my q6600 overclocked to 3.0GHz, with a voltage increase, CPU-Z is saying it is running at 1.408V. I have run plenty of Prime95 tests. No stability problems, and temperatures are always acceptable. I have had it at this overclock for 7 months, ran at stock the previous 4-5 years. My GTX 460 is overclocked as well, always has been stable as well, with temperatures plenty low enough.
