    I will certainly try all those things, they sound promising. I have 3 SATA hard drives, with several partitions, but:

    I agree. With all the different drivers I've been using, I think the ones that came with the hardware are the most stable. It still makes no difference to Call Of Duty 2.

    Thanks for the advice. I'll try calling Asus, but I'm in Australia so it might be difficult to find a local contact.

    It's a Shaw 450W power supply, and the chipset is nForce 4. It's 1gb of ram, 2*512. I'm thinking of buying another gig, but I'm sure that won't help this particular problem. Anything else it could...

    The card isn't overclocked, nor is any other part of the computer. The temperatures are fine, CPU never goes above 35, GPU never above 40.

    Games stalling, intermittently

    I'm having issues with games on my new computer. They sometimes work, and sometimes stall, and I think either DirectX or my onboard sound has something to do with it. Here's my specs:

    Thanks for the advice. I'll fix those aspects up, do some reading, and get back to you on the improvement I get. Maybe I'll even do some efficiency charts or something crazy like that.

    That'd be great if you could have a look. rsa_dll.cpp compiles to a dynamic link library, and rsa_prog.cpp imports it.

    I can't use the Chinese Remainder Theorem because the whole point is that RSA encryption keys are too large to factor, so I won't know the factors of whatever 'm' is.

    I have some value 'a' that I want to raise to the power of 'e', then take modulo 'm'. I split a^e into multiple factors, each a binary power of a. Ie: a^7=(a^4)(a^2)(a^1). I calculate each of those...

    I added some counters to check if I'm destructing all instances and deleting all memory. I lowered the exponent just enough so that I wouldn't get a seg fault, and both counters were at zero,...
