Hi,
I have an ASUS CUBX-E mainboard in my PC. For the past three weeks I am facing a strange problem : The registry of windows xp is getting corrupted quite frequently. I have re-formatted and re-installed windows xp pro several times but its registry is getting corrupted frequently, and I get the following error :
1. "Windows could not start because the file c:\windows\system32\config\system is corrupt or missing."
2. "Error : \system root\system32\hal.dll missing"
I have tried repairing the windows installation and the registry using recovery console from the windows xp cd but the errors reappears. Sometimes I get the error within few minutes after windows installation completes. However, I would like to emphasize here that windows xp installs everytime without error. Also Windows XP Pro with SP2 has all the drivers for my PC, so I never have to install any other drivers. So that rules out a driver clash or mismatch.
My complete PC specs are :
1. ASUS CUBX-E motherboard with P-III 750 Mhz and 256 MB PC-133 SDRAM [PCI REV. 2.2]
[Windows xp pro with sp2.]
2. Hitachi 80 GB HDD as master on promise ATA-100 controller.
3. LG 52x CD-RW drive GCE-8527B as secondary slave on 440BX IDE
4. Sapphire ATI Radeon 7000 DDR AGP with 64 MB VRAM (IRQ 11)
5. Compex RE100ATX Lan card (IRQ 12)
6. Pctel 56k softmodem (IRQ 5)
7. Yamaha soundcard (IRQ 10)
8. Onboard Promise ATA-100 CONTROLLER (PDC-20265) (IRQ 10)
9. USB ports and hub (IRQ 5)
I have observed/tried the following :
1. The problem begins after the installation.
2. Error 1 is much more common and as per microsoft is related to corrupt registry.
3. I have also tried using different XP CD but it did not help.
4. I have low-level formatted the hdd but it did not help.
5. I have changed the IDE cables but that also did not help.
6. the hdd has no bad sectors and I have tried using both NTFS and FAT32 install. No help.
7. The error/errors may appear after the first restart or after a few days. But they DO return.
8. I have RUN memory diagnostics Memdiag (by microsoft); DocMemory and Memtest86+ (1.70)
BUT NO ERRORS.
9. TESTCPU program shows no errors in processor, and Sandra2002 benchmarks are OK.
10. HDD diagnostic DFT v4.05 and v4.06 show NO ERROR in my Hitachi HDD (80 GB).
11. chkdsk /r sometimes helps (windows is able to start) but it reports NO BAD SECTORS either.
12. when the PC is running I am able to install my programs (MS-office 2003, Acrobat reader, winrar, etc.) and I get no errors installing or running them.
13. I have scanned the PC for viruses using Norton 2008 and Mcafee 2008 (Eval. versions) with latest definitions but they found no viruses.
14. I do get BSODs i XP like : 8E,50,7F,0A,77,24, etc... but anyone who runs windows knows that they are a part of everyday computing.
But RAM tests show no errors.
I have been using this configuration with XP Pro for the last three years without any problems. I am unable to locate any error in the PC RAM, hdd, add-in cards, processor, yet I am repeatedly getting this problem.
The frequent crashes and BSODs indicate a RAM problem but then why do Memdiag ; Memtest86+ and DocMemory show no error ?????
Could it be a PSU issue ??? Ambient temps in winter here is about 10-12 degC w/o heating. With heating it is 18-20 degC.
Years ago had a PSU (on a P-I 200MMX) whose fan wouldn't budge at low temps and PC would beep strangely on boot. But there a reset after 30 secs would take care and the PC would boot.
Now this system boots up but the regular registry corruption indicates hardware error but nothing has turned up so far. Even benchmarks in Sandra 2002 standard are OK & agree with sample systems values.
I am totally baffled !!! Can anyone help on this?
Any advise/suggestion would be useful.
