I have aDell Inspiron E1705 laptop with
Win XP Pro, SP3 . I have 2 memory modules of 1 GB each for a total of 2 GB RAM memory. It also has adedicated graphics card: NVIDIA GeForce Go 7800 (which has been replaced
with NEW cards of same model TWICE, after they burned out due to its cooling fan failure).
The system ran fine for several years until August 30, 2010 when the audio and video became intermittent (breaking up several times each second) until system froze - this happened while I was watching a news VIDEO on FoxNews.com viaAdobe FLASH player .
1.) On reboot, the system gets as far as the initial Windows startup screen, then I get the BLUE SCREEN with the following message:
***Hardware Malfunction ***
Call your Hardware Vendor for Support.
NMI: Parity Check/Memory Parity Error
***The System has Halted***
2.) I ran a BIOS pre-boot HARDWARE DIAGNOSTIC in whichONLY one of the VIDEO tests failed :
Error Code: 5300:0119
Msg: Detected a failure while writing and reading VIDEO MEMORY.Video mode: 0h (320x200x16) Address A0674h, expected to read 0h, but read 10000h instead.
3.) In "Safe Mode" I attempted a BIOS flash re-install, then a BIOS flash update, but it fails every time with the message that the"BIOS cannot be installed while a FLASH application is running" (even though I have opened NO programs) MP061 BIOS FLASH A09
Application return error: 0x00000610
Windows return error: 0x0000043c
4.) Attempt to "restore" the Registry from several working registry backups (made with "Advanced Registry Optimizer 2008" (by SammSoft) and Windows "System Restore" failed to make any changes to the registry.
Is this a Virus, Trojan, malware, etc? [Searches for same using McAfee AV, Spyware Doctor,Advanced Registry Optimizer 2008, and other softwarehave yielded nothing that corrects the problem.] A failure of the graphics adapter memory? Interference by a hidden process (FLASH program) running in the background? THANKS !
P.S. I am an advanced user with 25+ years of PC and network administrator experience in large corporations.
