So I built my system in summer 2008 and since monday my computer has been locking up for some reason, my mouse and keyboard stop responding. Then when I reboot my computer locks up on the windows load screen. No errors show which make this really hard, my components aren't overheating and I have no idea what to do. Normally I'd reformat and but my info on my external, but at the moment I do not have my vista disc and won't for about a month. I currently am running Vista home premium 64 bit, the rest of my computer specs are in my signature. Please people of Tom's hardware lend me your advice!!
