I installed some new components in my computer today and now it will not boot into windows. I had an x850 which I am replacing with a hd-3870. Right after replacing it my computer would freeze as soon as the windows login screen loaded. My first thought was messed up gpu so I went to go back to my old one and my computer would no longer turn on. replaced the power supply and it turns on. some how I messed part of the install up and smoke poured out of my x850. so now I'm stuck with a burnt x850 a hd-3870 that will not boot and a dead power supply. Furthermore, I thought well maybe it's just a drive issue but when I try to reinstall windows if freezes as soon as it brings up the install menu so I can't use the recovery console and I can't reinstall. If it is any help here are my complete system specs: athlon x2 5600+ with stock clock currently asus 580x motherboard hd-3870 512mb antec 500w powersupply(I know it's crap but my corsair that I just recieved was doa) 2 gb of ocz dd2 677 memory raptor 150 what should I try to fix my problem?
