Hi all, this is going to be a long read, and I hope I find a solution to it. Here goes My laptop (Acer Aspire 5738) is not more than a year old and was running on Vista home premium, about 2 weeks ago I received a BSOD with an error message BAD_POOL_HEADER. I searched google and related forums and the advice was to remove some files from the registry. Well, I couldnt figure out how to delete the files because it kept saying, 'Unable to delete'. I tried to delete the file as admistrator and gave the users full control over files however still with no luck. Then tried to use the built in acer recovery management however for some reason it would nt let me use 2 of 3 options. Keeps giving me a message 'Reboot Needed'.So I rebooted and yet again no solution to that problem. So yet again I searched google for an answer however was unable to find anything on this matter. A friend of mine then gave me his Acer recovery cd so I backed up my important docs and restored the pc back to factory settings. This process took a good 2 hours to take place. After the setup was complete I get a warm welcome message of WELCOME TO WINDOWS 7!!! He did not tell me that it was a windows 7 cd! I shouldnt be complaining right? Wrong, after the installation was complete and windows opened up I get another BSOD, 0x0000001E. And now the laptop won't stay on for longer than 2 minutes, slightly longer in safe mode. What I can't understand is why on earth didn't the laptop shut down when I was formatting for 2 hours and now it fails to stay on for 2 minutes? I used the Startup Repair feature on windows 7 however it found nothing. Any help is very much appreciated. I am sorry if this should be posted somewhere else or there are topics on this already however due to the format and upgrade, I thought I should post a new thread. Thanksamillion!
