July 2011 laptop Computer Manufacturer/Model NumberSager NP8130 / Clevo P151HM1 OS Windows 7 Home Premium 64 bit CPU 2nd Generation Intel® Core™ i7-2630QM, 2.0-2.8GHz, (32nm, 6M MotherboardCouldn't figure out Memory8,192MB DDR3 1333MHz Dual Channel Memory (16MBs now) Graphics Card(s)nVidia GeForce GTX 560M 1,536MB PCI-Express GDDR5 DX11 So I've started getting BSODs constantly, 6 the past two days. They happen at random. The message is IRQL gt zero at system service. After searching the internet a bit, I believe it may have something to do with: BitDefender ZoneAlarm (something I had a long time ago, but was removed) I downloaded and ran adwcleaner which caught about 15 issues, including some old ZoneAlarm, as well as something called Claro, which MalwareBytes had identified as a PUP. I have been unable to complete a MB scan, as it takes so long. I've reach around 1 hour 30 minutes or so before being BSOD'd. My computer also becomes so sluggish that it is nearly unusable while MB is scanning. BitDefender seems to clash with it, thus I try to disable everything I can on it, but still can't get past a BSOD. It began early yesterday morning. I just moved to a new apartment two days, and have a new router, but that shouldn't matter. The only things installed directly to the computer has been moving various USB's around to different ports that did the auto-install software. After reading, I thought about running Driver Verifier, but due to the ehhh aftermath of that, I want to work step-by-step with someone before even running it. I also just noticed this in Event Viewer that hadn't appeared after prior BSODs: The computer has rebooted from a bugcheck. The bugcheck was: 0x0000004a (0x000000007749132a, 0x0000000000000002, 0x0000000000000000, 0xfffff88009b17b60). A dump was saved in: C:\Windows\MEMORY.DMP. Report Id: 120214-18782-01. And I also just remembered, the first two successfully completed the physical memory dump at the bottom. The most recent few BSODs said "Physical Memory dump FAILED": I've attached the Win7 with CPU-Z screenshots and the Rammon. Please help. I'm wondering if this is something relatively easy like getting rid of BitDefender, or a driver or something. Did not have system restore enabled until now, and do not have a windows disk to reinstall windows right now. Do not want to do that if possible obviously.
