Hi guys, I have a major problem with my pc. A few months ago my pc developed a problem where it would crash at startup. The way to resolve this which I found was to let it do a memory check and then it would load fine. For the past 4 days it's been a nightmare. Even after doing memory check it crashes at startup. I tried logging into safemode and out. I CANT log into safemode+networking. I was totally locked out for two days then by some miracle after logging into safemode and out again it let me login (day 3) same thing again today but this time I had to log in a few times. I done a quick hardware check and nothing seems to be broken/no dust. How can I resolve this? I really don't want to re-format the pc. Running Win XP Home edition. (PS: also have problem on another pc which is many years old - stopped working two years ago due to same problem).
