I have a Compaq Presario SR1750NX AMD Athlon 64 3500+ Processor 1GB PC3200 DDR Memory 200GB 7200rpm SATA Hard Drive ATI Radeon Xpress 200 Integrated Graphics with 128MB Shared Memory Windows XP Media Center 2005 I have Updates enabled. Today I decided to update to SP3. After installing the update the system wouldn't boot. All I got was a black screen with the following options: Some paragraphs saying that last time windows didn't shutdown correctly some, some, some. and the it ask u what do you want to do.Then Safe Mode Safe Mode with networking Safe Mode with command prompt Last known working startup Boot windows normally. I tried these 2 options: Last known working startup Boot windows normally After I picked either of those options the system would just cycle back to the black screen with the same options of u know: Safe Mode Safe Mode with networking Safe Mode with command prompt Last known working startup Boot windows normally I finally booted in Safe Mode. Thats where I am Right now. But is running a little bit slow it freezes up a little bit. Can some one tell me how to fix this. Please? Im going fu!@#$% crazy up in here. PS. I do not know if this has anything to do with it, but Im running 3 OSs Windows XP Media Center Edition (my default one) Windows Vista Ubntu 8.04 Well after SP3 was finished u know it ask me to restart it so I did. But everytime the PC restart it displayed the OSs I have and from there u decide to go where ever u want to go. Well after the restart happened accidentally when into Ubuntu and then I went back to XP and thats where everything happened. Do you think that has anything to do with it?
