Hello, A friend of mine felt like formating his computer, because it was filled with a lot of crap and really needed to be cleaned out (he hasn't reinstalled for quite a while). He figured out how to get it formated himself and he tried to reinstall windows xp pro. Then he told me he could not get it to work and handed it over to me. I have tried to reinstall with a windows xp pro disc and a vista 64 bit (info on the system later). With the vista 64 disc, it just hangs when it has loaded, won't even go into the install. With the xp it installs, but I'm not completely sure if it actually installed it all, seemed a little fast. At least, when it reboots and tried to start it just hangs right after the "windows loading" and shows a black screen and nothing else happens (waited for 10 min. to see if anything would happen). I read a little on the internet and decided to see what would happen if I removed 2 gb of the 4 gb total. Tried a clean reinstall and the same happen with both discs. And now I got no more ideas (haven't had a lot of trouble with this for a long time, so I'm a bit rusty about what to do hehe). It seems like the motherboard is a MSI, it says "K9N SLI A7250NMS" when it starts up. (I don't have the right specs here, but I'm able to get them if it has to be even more exact). The CPU is an AMD Athlon 64 x2 5000+ The ram blocks are 4x1gb Corsair 800 mhz - CM2X1024-6400 The hard disk is a Maxtor STM3250 - 300 or so gb. There might be someone who had experienced it before and has asked about it, but I don't really know what to search for. I hope you can help me out here Thanks, LeCattez Edit: Oh yeah, I forgot to say that I'm actually able to go into Safemode without any trouble.
