Windows 7: Win 7 crashes when installing new software, everytime

Win 7 crashes when installing new software, everytime

Back story: two year old nephew hits the power button while I was browsing the net. Nothing out of the ordinary with it. However, since then everything has gone to batshit crazy. First ChromePlus, a browser, goes bad. It would freeze Windows the moment i launched it. I deleted that and things seemed to return to normal. Then the exact same problem happened to MSN Messenger.

So i deleted MSN messenger as well. And the PC is running perfectly fine, However, whenever I try to install something, anything for that matter, Windows crashes and eventually gives me a BSOD.

It seems it has locked itself. I have no idea what's causing it. I wouldn't like to reformat and I am hoping there is a solution to this. Unfortunately, for some reason, there was no system restore point! So can't do that as well. I am really hoping some of geniuses have an answer.

Windows 7


Following my issues, I formatted my PC. The PC ran fine for two days - i installed softwares, games, and watched couple of movies, and everything was just fine. But suddenly last night, it started crashing again.

CHKDSK fails. Rebooting from crash saying no boot device found. System restore didn't help either.

I am not sure what's the problem. Maybe the HD? But why would it run fine for two days and then error out so suddenly?

Any help would be appreciated.

Firefox crashes everytime I try to launch it.
It had too many tabs and it keeps crashing every time I try to launch it. Maybe there is a bug? I created another account and it works there well but I want it to work well on this account too. Turning the computer on and off didn't work.
