I run Vista Ultimate SP2 on a HP Pavillion m9080n Elite. For Xmas, I got a BSOD. After loading BIOS, the computer freezes.

Startup from HDD gives the error message, "IRQL NOT LESS OR EQUAL". The error codes are 0x00040061, 0x0000001B, and 0xE28F950E.

Startup from Recovery Disc gives the error message, "MEMORY MANAGEMENT". The error codes are 0x0000008E, 0xC0000005, 0xE2A495D1, and 0xC818A0C4.

Running Startup Repair gives the error message, "CLASSPNP.SYS Address 87630053 base at 8762B000, DateStamp 4549b196". The error codes are 0x0000007E, 0xC0000005, 0x880059B4, and 0x880056B0.

Running Repair Computer gives the error messages, "An attempt was made to write to read-only memory", and "PCIIDEX.SYS Address 8768771E base at 87685000, DateStamp 4549b196". The error codes are 0x000000BE, 0x0EDF9121, and 0x878046B4.

Running Last Good Configuration gives the error messages, "DRIVER IRQL NOT EQUAL OR LESS", and "ecache.sys Address C8B92971 base at C8B8A000, DateStamp 49e01f2c". The error codes are 0x000000D1, and 0x0000001E.

Entering Boot Menu gives the error messages, "Run Driver Verifier", and "Enable Special Pool". (WHAT ARE THESE?) The error codes are 0x0000000C5, 0x3955FEA3, and 0xE33387D5.

I am unable to run System Restore; the computer freezes.

What is happening here?

Can you enter the BIOS and change default settings, hard disk mode or remove the CMOS battery for a couple of minutes for a hardware reset?

Try jhayz's suggestions first. Any success?

If not, I'm thinking bad memory module.

If you are able to get into HP Diagnostics, test hardware, especially memory.
  • Restart computer | press F9 at HP logo screen | select Diagnostics
  • If HP Diagnostics isn't available and only if the computer is NOT under warranty and you feel confident working inside the tower:
    • Remove A/C power cord from tower and press and hold the "power on" button for 30 seconds to drain all current from the board.
    • Remove the memory modules and spray each slot with compressed can air.
    • Take care to avoid static electric discharge and to avoid touching the gold contact area of each module.
  • If you have more than one module, replace only one module (consult motherboard manual for proper slot to use).
  • Attempt to restart computer.
  • If no success, try a different module.
  • Exhaust all available memory chips, then try a different motherboard slot.
