My son recently got this MB on eBay to replace the same MB he was running\nwhich had a broken SATA connector. The first AV49P/N was running perfectly\nfor almost a year until he wanted to add another SATA drive. After swapping\neverything, WinXP booted just fine but shortly thereafter kept giving\nbluescreens. He ran memtest and would get errors right away. He put the same\nmemory sticks in another computer and got no errors after 12 hours. These\nwere the same memory sticks from the previous AV49P/N. The CPU that came\nwith the MB was so hard to remove from the socket that one pin of the CPU\npulled out! It was a ground pin so that CPU is still good.When he pulled his\noriginal CPU out of the new MB, it was also very difficult to remove, but\nfortunately no broken pins this time. Any ideas what can be wrong with this\nboard or the CPU socket. The seller won't respond to emails, so I guess\nwe're stuck with it. He put everything back on the original MB and it's\nrunning perfectly (except for the broken SATA connector).
