Windows 7: Random BSOD after start and Random stuck on windows logo screen

22 Jan 2015   #1

Windows 7 Ultimate x64
Random BSOD after start and Random stuck on windows logo screen


So yesterday due to a sudden power outage (happens allot here), my windows started behaving erratically.

First when the power came on my windows 7 ultimate 64 bit, was stuck on windows logo. i waited for about 20 mins and it was still stuck. The HDD read activity light on my casing was active the whole time and it was red.
i restated the system and the same thing happened. I tried the safe mode and it didn't boot..It was stuck at classsys.pnp with solid red light of HDD..i restarted my system again.

After about 10 restarts the system finally booted up after ..i thought the problem had been solved but after 10 or so mins a damn BSOD appeared..i restated the system and the same thing..stuck at the logo with constant read activity on HDD..
Today also..the same things..stuck on logo..restart again..after 3 tries windows starts..then BSOD..then again stuck on logo..Its has become an unpredictable cycle of what the system will do next..

The exact same thing had happened before about 3 weeks back, and i formatted my HDD and reinstalled the windows new..Now i dont know what to do..Is it a software problem or my hardware like motherboard, RAM or HDD is failing..plzzz help urgently..

PS..i have attached my crash dump and other files necessary fro evaluation.

Test your HDD with Seatools for DOS. Take both the short generic test and the long generic test.

Let us know the results.
