Hi, I've been working on this problem for about 5 days now. I have a compaq presario SR100 Running Windows 7 Ultimate x64 AMD Anthlon 64 3500+ Processor NVIDIA GeForce 6150 LE Graphics Card 2GB of DDR2 RAM I've had this machine for about 3 years now, and it's been running Windows 7 for close to a year. This was the same OS and version as i just put on. I did a routine reformatting to help speed up my computer. Setup ran smooth until it was preforming initial setup, where is had a BSOD (Driver_irq_not_less_than_or_equal). I haven't had a single BSOD since. After startup everything ran smooth. It wasn't until my first update where i began to have some issues. After startup (3 minutes in) my PC would begin to lag completely. This would occur for about 5 minutes until it would completely freeze, requiring hard boot. nothing else has been installed besides Windows Updates. I have the minidump file here http://cid-c63a80925183c1c3.office.live.com/embedicon.aspx/.Public/010211-35281-01.dmp And the Event Viewer Log of my machine the run where it did freeze up. There are a lot of, Installing Failed, errors but that's most likely because i cancelled the installer at one point. http://cid-c63a80925183c1c3.office.live.com/embedicon.aspx/.Public/events2.evtx If there's anything else needed i'll be happy to provide.
