Its fixed now but i'd like some info on this if you have any please,

Yesterday morning i had updated a driver for my D-Link Adapter, when i had restarted it had killed my internet. So i did a restore and it was fixed until i got on GunZ, after 10 minutes of playing it shut down...sometimes this happens(no stop screens) so im like ok fine ill just turn it on again..until it reached the user screen...BSOD'ed. I freaked out because i had NEVER had any problems with my computer and ive had it for 6 years, no major viruses, crashes blue screens, until now. So i booted it in safe..did another restore..to about 2 months ago. It completed succesfully so i tryed in normal mode again and i received another BSOD. then i tryed safe mode w. Networking, unsuccessful...blue screened. So i called Dell tech support, they didnt really help but i admire their information, i ended up flashing my BIOS(now when i boot up i get "Value Deleted: BootExecute Hex:7:0:0) and running the tests you do in your BIOS. Everything was fine. so i gave up on tech support and tryed working myself. so finally, the thing i forgot, unplug all hardware, i unplugged my adapter, started the computer and hey guess what it booted PERFECT, so i plugged back in and i got BSOD'ed. as i saw the BSOD i noticed a file called A5AGU.sys. In normal mode i found out it was a D-Link Adapter driver, so i called D-Link, and ended up reinstalling and everything worked perfect. i spent 7 HOURS before i unplugged the hardware -.- . Does anyone know why this file was corrupted? I dont think its the update because i restored it worked fine =| .

Thanks,
Nick

An file could have been corrupted by another program accessing it, by normal degradation of the magnetic charges on the hard drive, or by almost anything else that affects the file system/structure.

The update could have been:
-corrupted on their server
-corrupted while transmitting the download to your system
-corrupted while executing the installation on your system

The usual "fix" is to re-download and try again (after removing all the previous stuff).

The system restore likely restored everything to a time when it wasn't corrupted (so, the corruption occurred sometime between the system restore date and when you first noticed it).

So, keep your eye open on what you're doing for a while (just in case the problem pops up again) - it may help you to determine exactly what caused the corruption.
