Greetings to all you great people here. I've already learned a lot by just reading. However, I have come to a dead end. This problem seems to be appearing more than once and I'd like to learn how to fix it. I'm starting in the Win XP forum, but this may end up belonging to the Virus etc, forum. Here's the situation:
I have a computer that suddenly stopped working, and refused to boot. I get the bsod and then Windows immediately reboots.
I managed to capture the stop code. This is it: STOP: 0x0000007b (0xb84C7524, 0xc0000034, 0x00000000, 0x00000000)
So my first question about this is what do the extra parameters mean? And are they useful in any diagnosis of the problem?
What I already did before posting:
* I tried booting in safe mode -> same BSOD -> instant reboot
* Returned to "Last Known Good Configuration" -> none was found. At reboot I got same BSOD and instant reboot.
* I tried to run the Recovery Console, but was left with a blinking cursor.
I downloaded a bootable disk from AVG (Rescue CD) which will scan the computer, but it didn't find or fix anything. This cd has a program called TestDisk that looks at the partitions, but everything looks good. It also looks at the boot sector, which it said was OK. I can't remember exactly what it looked at, but noticed that the original and backup were the same, which was concluded to be good.
I booted up to Active@ Boot Disk and ran CHKDSK /R but it didn't find anything. I also looked into the file system and can see all drives, partitions, files - everything looks normal. All the boot files are there. Boot.ini looks OK.
Finally I found the XP installation disc and ran Recovery Console and for good measure ran chkdisk /R again from there. It did say that it found errors and fixed them but I still have a bsod. I also ran fixboot, but no luck there. I did not do fixmbr since the first HD is partitioned and I was a bit worried about ruining the partition table (should I be?). I tried to run a WXP install -> repair, but strangely enough I couldn't get past the Licence acceptance screen. It was as if my F8 key was dead. I could page up and down or Esc to reboot, but no F8 - is that suspicious?
There has been no new hardware installed recently. The computer has 3 drives in it, the first is partitioned into 2, so there's 4 drive letters. BTW, I had to change the BIOS setting for the SATA drives to IDE from AHCI to get the Win XP disc to work. Then the stop code changed to 0x0000007E.
At this point I am faced with (I think) two possibilities. Either something's wrong with the HD controller or driver, or there's a nasty virus. If I can read the HD contents when I boot to ABD does that mean the HD controller is OK? Since TestDisk said the boot sector was OK does that rule out a virus? If the driver is corrupted can it be replace manually from a bootable CD? Fortunately there's a backup of all the data, so that isn't a worry. I'd just like to know what's going on. This has actually happened to two other computers which are, incidentally, on the same network.
Lots of questions.
I have at my disposal a BartPE disk as well as the above mentioned disks. I haven't used BartPE yet.
Thanks for reading all this and your willingness to help us out.
