I have a fairly new pc (two months old). Since I have the PC, it keeps crashing every two or three days (or sometimes two times a day). The system gave me the 0x00000050: PAGE_FAULT_IN_NONPAGED_AREA stop error. This is the error that I got time after time again. I can not detect any logic in it. One time, I was running a virus scan and a defrag (PANDA antivirus and Auslogics Disk Defrag). Another time I just started Photoshop. As there are like 20 reasons why you can get this error and it is nearly impossible to test all of them in a short time I decided to completely reinstall my computer. So today I did a clean install. I formatted all my harddisks and the filesystems and reinstalled a clean copy of Windows XP Professional. A few minutes ago, my system crashed again. However, this time it was giving me a different error, namely: "Error code 0000001a, parameter1 00041785, parameter2 c0e00000, parameter3 00036f8f, parameter4 00000000" I had photoshop open, Google Desktop was indexing and I was browsing with IE 7. My computer is driving me nuts and I have absolute no idea what is causing these errors. One thing that happened is when I restarted my PC speaker (i guess motherboard) was giving alarm beeps. Does anyone have an idea what is causing this errors? I think I am going to call the store where I bought my PC tomorrow as I am almost 99% confident that this is a hardware error or a driver error. At times like this I really wished I stayed with Apple. If you like to have additional information feel free to ask because at this moment I am not sure which files I could send you.
