Cooler Master Elite 330 drivers?  

I'm a complete noob when it comes to computers. Background on my issue:
I was running on Windows Vista (Home basic I think) when AVG detected a virus; I closed my other applications (as I was about to go out anyway) and ran a scan (full scan) with malwarebyte's anti-malware. I then went out and walked my dog. When I returned my computer had rebooted, I logged on and for some reason explorer did not load, I opened malwarebytes again via the task manager, whilst it was scanning I also decided to look for a process that may have previously caused the reboot. I noticed there were TWO coppies of crss.exe running, so chances are one was the virus. As processes run in RAM, and neither had any info, I decided I'd end the first one, if it wasn't that, I could restart and end the 2nd next time. I kill the process, get BSOD and then my computer rebooted, however wouldn't load. It loaded to an empty command line with no text. I waited a small while, nothing changed, I rebooted, again, nothing. I asked online and was told I needed to format and re-install OS. However I had lost the installation disc for vista (vista sucks anyway) so I got myself a copy of Windows 7 ultimate, (64-bit, I've got 3GB RAM).
My problem: Upon loading the disc (booting from disc obviously as I could not boot from the HDD), I accept the terms blah blah blah, select "custom install (advanced)" (You coulda just put "fresh install" btw); and it takes me to a form where I have to select the driver... Except it's blank, and can't find anything. As I said, I'm a complete noob with technology, however I do believe drivers are the software required to run hardware? My computer model is the title thread; but I have no discs for that. I really don't know what I'm supposed to do, can someone please help me out? Thanks.

Well I can't get on the computer exactly, as to my memory I had roughly 500GB HDD, and 3GB RAM, no graphics card. I was running on Vista Home Basic 32 bits. What more information do you need? And how do I find it out?

That's indeed what I'm saying... *Opens case*
Wow, lots of dust, made me choke, it says on the label of the motherboard:
01798P7C0063004BD1DACLF

Damnit, I strained my eyes and used a torch to be able to read that label
ATA 133?

DDR11800?
SATA II?
Way too much stuff written on this thing.
