I had a virus a month ago and I decided just this last weekend to remove it. I installed Kaspersky and it failed telling me I had a virus and I needed to install their Virus removal team first. I did and it found a trojan/virus and told me I needed to reboot to remove them. I rebooted and got my first blue screen of death. I restarted pc and it kept freezing at start up logo. I decided to use the first option, which was repair and it system restored it to previous day state and it worked. Then i rebooted a few times over next few hours and was fine until I did it one more time and same issue. I formatted/reinstalled windows 7 and this time my pc would randomly reboot and give me same blue screen and only windows startup repair would fix it. Yesterday it worked fine throughout the day, playing Max Payne 3 and all and shut it down at end of night and then issue arose again this morning. Can't get into Windows normal. Just hang/freezes on Start Windows logo and repair just hangs during loading. What is causing this and how can I get back in my OS? Safemode does not work as it freezes there too. Is this software or hardware related? This only started happening after I tried removing that virus.. But it cant be related to this because I have formatted/reinstalled windows 7 twice. The last time the Startup repair worked, half way during the "Attempting repairs" process, I got a blue screen of death there too which said something like Executive system... or System executive.. I don't remember to be honest.
