Ok, I have a very very strange problem. Not sure what category should I put in, so move it appropriate category if you would like. I have an assembled computer, i5 3rd Generation, 1 TB, 8 Gigs and a 500 mb nVidia graphics card. I have only one fan. This pc has Windows 8. It worked like a charm. Suddenly it crashed, and refused to boot. Tried lot of different things. Re-installed my OS and then it worked for few hours and then crashed again and every time it crashes, refuses to boot completely. This is what I have found, I use computer for sometime, it freezes (the fan keeps on running) and it stays frozen until you manually forcefully restart it. Once you restart the machine, it doesn't boot. So the workaround I have found so far is: switch off the computer, remove the Hard disk Sata Cable from either of the point, add it back. Start the PC, and it boots. Sounds funny? yeah, but it has screwed my productivity for so many days now, I cannot work, and really dont have time to go to hardware shop and hand it over to him for a few days, please help...........

Appreciate your help and time to debug this issue. It can save me hours.

Thanks,
Vikas
 
Well, let's check if it's not overheating. First thing you may want to try is to launch some kind of temperature monitor. There's a lot of apps that can do it. First link in Google leads to http://openhardwaremonitor.org/ that seems to even be free. What temperatures should you monitor? First one - CPU. Normally it shouldn't be over 50C without load (even this value is high enough). Second - Videocard temperature. About the same value. Third - HDD temperature. Without coolers it may be high, but I don't think it will be too high, but check. Also, would be good to check the PSU. Maybe it's overheating or became faulty? Check if there's dust on the metal cooler under the CPU fan. If there's, clean it. Plus what does "it doesn't boot" mean? It means you push the power button and nothing happens or something starts to work and then stops? Or OS goes to BSOD? Also you may try to start working without the left side of the computer, so that air goes inside and makes cooling a little better. If nothing of these solutions works, we'll think what to do next.
 


Thanks, Doesn't boot means it tells us that there is a problem in boot device and it cannot boot. Gives the error message. What I don't understand is, if it is heating issue, then why it will refuse to boot next time? Doh, anyways, following is my analysis of the temperature monitor tool:
