your the 2nd person who told me that cooler master doesn't make good PSUs. I have checked several calculators and I'm above the recommended min. and thats with everything that runs off my PS. Before I start buying stuff, I need to know whats causing the problem.

Without symbols configured, that output is not helpful. Also, the file is binary, meaning it is searchable (which is what we do with it), which is where it's useful. So if it's too big to zip up and post somewhere, it's not going to be much help to any of us unfortunately.

The memory dumps do actually point to memory corruption, although it's not 100% clear if it's a driver issue or if it really is a RAM issue. You mentioned earlier that you had tested the memory earlier, so that would leave potentially a software issue. The PSU could still be an issue if the power is not sufficient or clean, but I leave that to the hardware folks. However, the error really is happening when reading memory due to an invalid memory address (passed in via an invalid PTE), but it's just not easy to say whether it's a software or hardware issue.

When you said you tested your ram did you use memtest86 and did you run it for at least 8 passes? If not, I would suggest you download free memtest86 and run it at least 8 passes (which will take several hours. 7 on my machine). Download the ISO file and byrn it to disk and boot from the disk. They also have a version that will install to a USB drive.

i tried the ram in another system and it was fine, and I ran memtest86 for 4 hrs, I'll run it again overnight.

Coolermaster has a decent 600 watt unit here. The unit does pretty well for stability and efficiency, doesn't get very loud, and... what? It's a 750 watt unit?
More at Johnny Guru.
This is a link to the last review page. Fortunately it has a 5 yr warranty. While the PSU may not be the root cause of your issue, I think you should look into it. If it is bad you could end up with more problem, such as a motherboard fried.

Also test your RAM modules individually. Then with all installed.

ok, I did 10 passes with no errors, with both sticks of RAM. Over the next few days, I'll test the individual sticks. I think I'm going to get a new PSU, because I'm begining to worry that this coolermaster wont last long, and like you said, could end up frying my computer. do you have any suggestions for PSUs. I'm looking for the best so price isnt really a concern, with around 800-900w.

In my opinion the best PSU's are Corsair, Antec and Seasonic. There are some other good ones, but I think those 3 are the best. Best suggestion is go to Newegg, pick some out and spend some time reading customer feedback on them. Reading the reviews from those that use them will give you a better idea of which ones are best.
