First of all, specs:
CPU: Core i5 750 @2.66 ghz
Motherboard: Gigabyte GA-P55M-UD4
RAM: 2x 2GB Corsair XMS3 @1600mhz
GPU: Ati Radeon X850XT 256mb
HDD: 2x Seagate 160GB SATA + WD Black 500GB
PSU: Corsair 550W
Other components: 1x no name DVD reader, 1x no name DVD burner
Case: Antec P180 Mini
All wires seem correct.
Now, here's the problems and what I have excluded:
* Every time I boot XP SP3 from one of the Seagate hard drives, I get a blue screen with a STOP 7b error after the XP loading screen has filled one "bar".
* When I boot Vista from a friend's hard drive, it sits in the loading screen for a while then reboots
* I have ran memtest86+, no errors detected
* The graphics card worked in the last PC, it's from another PC
* The two seagate hard drives are from another PC
* The DVD readers/burners are from another PC
* There's also a wireless network card plugged in, but I severly doubt this is the cause
* When I pop in the installation disc for XP (I have tried two separate ones), I have got these problems:
# Error at line XXXX (478 or 6591 for example), this occurs before it starts loading
# Blue screen after loading some drivers, I have got several different errors
# Sometimes it loads all the way through. I get to the formatting menu, and I try to format a hard drive. It jumps first to 20, then to 100% and says that it could not format. If I try to format a 160GB one, it does the above and I get kicked back to the menu. If I try to format the 500GB one, it tries to format the 160GB one with the above result - and then says that it could not format, and that Setup must be exited, where it automatically reboots my computer.
Another problem I have is that the RAM seems to be ran at 1333mhz at timings 9-9-9-24 in BIOS. I think it's supposed to be 1600mhz @8-8-8-24.
Thanks!

Well, there are so many *possible* things it could be that I will just have to answer generic things to do
0. I assume you ran Seagate disk drive diagnostics. If not do so, you could just have a bad disk drive.
1. To eliminate the disk subsystem entirely, get a big USB stick and load XP on it, and see if system behaves. If system works when booted to USB, then you know it is seagate disk or disk controller/cabling. Otherwise continue down this list.
2. If this is a system you bought that was fully assembled, just take it back, not worth the effort to debug (maybe this is a full commercial system, and you just swapped out the graphics card?
3. If this is a fully homegrown system then based on what you have already tried, then you probably have interrupt conflicts, timing issues, or basic hardware incompatibility that just prevents the entire system as a whole from working. Sorry about the soapbox, but you just learned why PC manufacturers like Dell, HP, IBM spend tens of millions of dollars designing any new computer .... they check compatibility. So even though every component works perfectly stand alone, the system as a whole fails. You have a frankencomputer, and have probably spent way to much time trying it to all work. Here is what the pro's do ..
Go to http://www.uxd.com and get their diagnostic card. (There are many other companies to choose from, I am just naming one that I have experience with). This card has it's own processor, memory, display, etc ... and will figure out where the problem is, whether it is interrupts, signaling, memory, cpu.. All guesswork is removed, and it will tell you exactly what the problem is ... which may or may not be fixable.
Now, there are many other PC diagnostic cards, and the uxd family is expensive. It may not even be cost-effective. Look on ebay for PC diagnostic cards and go to websites to find one that you can afford that you think is good enough to diagnose the problem.
But just don't waste a whole lot of time trying to run further diagnostics. Based on your question you pretty much ran all the diagnostics you can run that are based in software. Component incompatibility problems rarely show up in diagnostic software. This is a classic example of when you need to purchase diagnostic HARDWARE.
