I have had my comp for almost a year now, but it started to froze every time when it finished loading windows. So I reformat the HDD, ever since I have been trying to install windows I got errors. I kept doing the reformat process and now it only says when I try to install windows "The image ntvdm.exe is possibly corrupt. The Header checksum does not match the computer Checksum" been having this prob for a week now. Though I could fix it myself, but now I really need advice. Need to do so much work in my computer but can't cause I'm having this problem. Any kind of help would be nice
