The most popular Blue Screen of Death error in Windows is the STOP 0x0000007B error, sometimes called the 0x7b error or the "INACCESSIBLE BOOT DEVICE" BSOD. This BSOD (which is actually the common name for a STOP Error) could mean that there's a serious hardware problem with a hard drive controller, a driver issue, or even a boot sector virus. In your case though, this is most likely one of 4 capacitors that are known to blow out on any SX270. Slide the bar at the back of your PC to the remove cover side and look inside for swollen caps. Remove the fans and cpu cover as well and check around there. Replace any bad ones you can find with old caps borrowed from an old motherboard if you have one, or new ones from any decent electronics parts warehouse. This fix has worked for me on every SX270 I have ever had.
0x0000007B Blue Screen Errors in Windows XP Some Dell computers ship with both ATA and AHCI support. Both are methods for communicating with the hard drive. AHCI has benefits above standard ATA mode that increase performance. Microsoft® Windows® XP does not support AHCI mode by default, which causes the STOP 0x0000007B error message if AHCI mode is enabled before the AHCI driver is installed. To resolve this error, disable AHCI mode (by changing the SATA Operation setting in the System Setup), and then install the chipset driver. When the chipset driver is installed, you can enable AHCI mode. Change the SATA Operation Setting From RAID Autodetect / AHCI to RAID Autodetect / ATA in System Setup 1. Restart the computer. 2.
