Hi everyone, After restarting the computer following a malwarebytes scan, I could not get into window, nor safe mode and system restore by pressing F8 at start up. What I only had after running a little while is BSOD. Btw, I ran diagnostic test a few times. All passed. After this happened and I did some searching online, I decided to run a windows xp repair by using the original OEM window xp installation CD (sp2) when the system inside the computer is sp3 after I updated it long ago. I followed the processes suggested by the following webpage. http://www.windowsreinstall.com/winxphome/sp2sp3installxpcdrepair/indexfullpage.htm It was all fine until Part 4 in that webpage. A BSOD popped out after the windows symbol in Part 3. And I noticed some new sentences at the bottom of the BSOD which are like ‘physical memory dump’. Hopefully, solutions for all of this would be recommended by someone. I don’t even really dare to switch the computer back on now! Sorry if I have posted in the wrong section of the forum. If I have done it, please move this post to the right section. Thank you in advance.
