D900K/NP9750 woes :(

After a year of problem-free notebook-computing, looks like my D900K/NP9750 (aka Game Xplorer X64-Ultra by CyberPowerPC) is experiencing troubles. It all started with BSODs, constantly checking/uninstalling/reinstalling drivers, to now reformatting. I thought I was home free with reformatting, but I guess not. I noticed most items I download off the net OR even copy over from a network share get corrupted. I ran memtest86 and all seemed fine (2 passes). It's not all downloads/file copies though; i tried copying with both the wireless and even gigabit ethernet, same results... Right now, I am swapping in some known good working memory (256MBx2 PC2700) sticks to try to reproduce the problem. Luckily I backed up all my files beforehand to an external. I just tested the system with the good/spare memory, and the system isn't corrupting copied/downloaded files.

 

Hmm... if your MemTest's ran fine...

then I would check:
- your HDD (swap it with another if possible)

 

I agree with the previous poster. It sounds to me like your HDD is failing, maybe one of the heads is gunked up and you are creating ton's of bad sectors..

Maybe you can get your hands on either a Linux LiveCD or Windows PE and give that a test since it would bypass your HDD altogether.

 

it was definitely the memory. I ran a BartPE disc, bypassing the HD and it blue screened a few times. I swapped in good memory and ran BartPE for the same period and it never blue screened again. I remember, with the old (suspected bad) memory, Windows setup would complain that it couldn't read files off my Windows disc (since it obviously goes from CD to memory to hard drive). I ran windows setup with the good memory and Windows setup didn't complain about the CD contents not being readable. My optical drive and CD were clean from the start. The system is up and running and a lot more stable than before. I notice CyberPower put in generic crap, so I bought some Patriot SODIMMs in there.

 

nice to hear.
