Original mobo (Trigem Imperial) in eMachines T2682 (I know, I know...never again) experienced partial failure. I installed new power supply, and discovered that the USB ports and audio were nonfunctional. However, Celeron 2.6 processor, RAM (2x256), HDD, floppy, CD and DVD drives all continued to function normally.
Decided to replace mobo. Backed up all important data files to CDROMs.
Purchased & installed Asus P4V8X-MX microATX mobo. Installed processor and RAM, connected up devices, LEDs, power switch, etc, no problem.
Powered up the machine, went to BIOS setup. Confirmed that CPU, RAM and drives were all recognized by BIOS. Hit F5 to set BIOS settings to default (which includes "no" setting for plug-and-play OS).
Exited BIOS, let system attempt to boot. Got to screen that states "OS may have been shut down improperly" and includes options for booting in safe mode. I selected "boot in normal mode".
The system only ran for about 2 seconds after making that selection, then initated a reboot, again arriving at the "OS may have been shut down improperly" screen. I tried the "boot in safe mode" selection, same result. I powered the machine off, removed battery, did jumper moves to reset BIOS to default settings. Powered back up, same result.
Then I powered down, substituted a smaller HDD from another computer that had W2000 on it as the primary IDE. The machine booted up normally. Hmmmm...
The XP OS on the original HDD is the OEM version that was shipped by eMachines. The computer came with a 3-CD set for "product recovery". I went into BIOS, set the CD as first boot device, inserted CD#1 of product recovery CDs, and rebooted. The product recovery screen came up, with its warning that proceeding with recovery would result in loss of all data files. In my opinion, if the original HDD with original copy of OS on it (still functioning up to the time I removed the original mobo) won't boot, why would I expect the OS to boot after doing a 'product recovery', right?
So I aborted the product recovery, and that's where it stands presently. Does anyone know:
1) Is there a process that I might use to get the original OEM OS to boot up with the new mobo?
2) Does the 'variant' of the XP OS provided by eMachines need to determine the presence of an eMachines mobo before it will boot up?
3) Is this potentially a driver issue, and if so, should I reinstall the original mobo, get the system running, and pop in the CDROM that came with the new Asus motherboard? If so, what should I attempt to install from the motherboard CD?
thanks in advance!
