I have been experiencing problems with my internet connection for the past one month. I must have caught a virus, because every time I went online the whole network in the office wouldn't work. That used to upset my brother, so for a month I haven't touched my computer. Yesterday my bro left for a few days and I thought to fix the problem on my PC. I tried to reformat booting Windows XP from CD, but it didn't work. So I went to the Bios and made sure *Boot from CD* was the first choice. Still it didn't work. I tried to reformat from floppy in Dos. Again I went to my Bios and changed the first option *Boot from Floppy*. Guess what? It didn't work. So I thought to over-write Windows XP on top of the existing OS. That worked. But the old problem persisted. Every time my PC was on, the network collapsed: no computer could access the internet. I am pretty stubborn and don't give up easily. I thought that maybe now I could try and reformat. I went back to the Bios, made some changes, saved, rebooted, and now all I get is an error message. *** STOP: 0x000000ED (0x8179BAF8, 0xc0000032, 0x00000000, 0x00000000) I tried to boot in safe mode and I failed. I tried to boot with the last known working settings and I failed. All I get is this error message. I looked around the internet for answers, I couldn't find any solution. How to disable the Bios memory options? To be honest with you I have no clue on where disabling the memory options will bring me, but it's one of the things that comes up with the error message: *Disable Bios memory options such as caching or shadowing* Where I start from? Any help is truly appreciated.
