Blue Screen in laptop with clean installation of Vista (Zone Alarm?)

Short after doing a clean installation of Vista on my HP dv6700t, I started getting the blue screen of death. Actually it happened twice in the first few minutes. I had installed Office, I think, and AVG and Zone Alarm. After installing all the drivers from the Swsetup and HP website, the Blue Screen problem doesn't happen that often, but occasionally I still get the Blue Screen with a 'IRQL less than or equal' message.

I've been doing some research and apparently, there are a lot of reports of this sort with Zona Alarm and the 'IRQL less than or egual' BSOD. I also have ZA on my desktop and everything workd fine. It's just the laptop. Any ideas what should I do?

PS. I ran Memtest86+ with a RAM I bought off Ebay and got 3 errors. I removed it, used the RAM sticks that came with the computer, ran the test, it showed no errors, restarted the laptop, and a few minutes later I got the BSOD again.

 

There are a lot of BSODs, and without a full error code, no one would be able to help you. So the next time it hits, take a full note of it, and post it here, and then maybe we could help.

 

IRQ errors generally mean a conflict with one of your devices. If the BSOD happens pretty consistantly to the point where you know if its going to happen or not, what I would do is open your device manager and go one by one disabling devices (obviously don't disable the necessities such as a monitor) untill you don't get a BSOD anymore.

 

I don't like Zone Alarm and it's a pain in the neck to uninstall because it leaves bits and pieces in the registry. Office and AVG works well with Vista so my guess is Zone Alarm is the culprit.

 

Thanks. I replaced the RAM stick and the problem is gone.
