Hi all. I have been reading some of the threads on here about agpCPQ.sys problems, and although they have been very helpful, none of them are exactly the same problem as I have been having. I didn't want to go ahead and follow the advice, just in case it would make things worse. I have a Gateway Notebook MX6923b, running XP. I use this computer solely for running my business from and I have always kept it updated and virus free (as far as I know) and last Monday it wouldn't boot up. I haven't added any new software, there has been no new hardware attached. It was running perfectly on Sunday evening, and turned off and powered down properly as well. When I turn it on, it goes to the Gateway screen and then straight on to the screen saying "We apologise for the inconvenience...etc" and gives 5 options: Safe Mode Safe Mode with Networking Safe Mode with Command prompt Last Known Good configuration Start Windows Normally When I choose the either of the last 2 options, it goes straight to the Windows XP screen, with the loading light running along under the image, and then nothing happens. I have tried leaving it for hours to see if it will eventually start up but it never moves off that screen. When I choose either of the 3 safe mode options, I get lines and lines of writing, which at the end it says : multi(0)disk(0)rdisk(0)partition(1)\windows\system32\drivers\agpCPQ.sys and then it hangs on that for ages, and goes nowhere. At this point I googled the "agpCPQ.sys" to see what it was, and up popped threads from this forum. So having gone through all this, and having read excellent advice from here and from Microsoft having issues with agp440, my questions (after all this writing) are these: What's wrong and what can I do? Will I lose ALL my data and files on the hard drive if I use the recovery disk?(I know, I know, I should always back up my info and I do usually. Losing the info is absolutely not an option) Is there any other way to get round this without having to use the recovery disk? Can I do anything in the BIOS or BOOT menu screens? As a last resort is there any way to recover the data and files off the hard drive? Please help! If there are any other details that you need to diagnose what's wrong and how to fix it, I will try to give you it. Thanks for reading and for your time in helping me out.
