Ok, so I have a Compaq Presario SR5023WM that originally came with Windows Vista, but I installed XP Professional SP2. Now, today I went to update it to SP3, so I downloaded it and installed it. It told me I had to reboot, so I did so. But now when I go to start the computer back up. It makes it to the screen with the XP logo and blue loading bar, and right after that, it shows a blue screen of death saying."STOP:c0000139 {Entry Point Not Found}
The procedure entry point GdiGetBitmapBitsSize could not be locared in the dynamic link library GDI32.dll."

Now, I have no clue at all as to what this means. I've tried booting it in safe-mode, no luck, same error pops up.So somebody please assist me with this.
