On my friend's older (recently upgraded) Compaq Presario 6010US w/ XP Home, this morning after being powered off overnight it hangs in the boot screen. Once, out of 12 tries, we were able to get into Windows XP safe mode, but after that, when Windows XP home starts to load normally, it just quits and kicks back out to the initial boot screen, and hangs there, as though waiting for a command. Even F10 which loads BIOS is sluggish, taking a couple of minutes to load BIOS. I tried changing BIOS settings to Full vs Quick POST (Power On Self Test) which I think helped us get into Safe Mode, but, no luck booting to normal mode of Windows XP. Then we tried using the ATI Rescue CD (v 9.2323), and it snaps to attention , loading Acronis at once, then using the 3rd option to Continue Loading Windows, XP Home loads normally as though nothing was wrong. So, it seems that the BIOS is hung at some point, perhaps asking the CD drive for a bootable option, though, no such message displays during Boot, even with info enabled in BIOS. Boot order is CD/floppy/HD. After recently rebuilding this PC we did not do a fresh install of Windows XP Home, which I understand might be the problem, as a new HAL (Hardware Abstraction Layer) was not created. Yet, once in XP, everything runs fine. Compaq Presario 6010US Socket A Motherboard AMD Athlon XP 1600+ added RAM (now 1 GB 2x 512MB DDR 2100) New WD 40 GB "C" ATA 100 system drive - full format - Primary EIDE Recent & good Seagate 100 GB "F" ATA 100 Data - Secondary EIDE (both HDs are jumpered Cable Select, on the same channel with a new Cable select cable) new AGP MSI 256 MB NVidia GFORCE 6200 Video card new Antec Earthwatts Power Supply new Via 1394 Firewire Card LITE_ON CDRW LTR-24102B new DVD_RW drive NEC ND-3520A new Antec Case (noted here as the power switch cable needed to be reconfigured to fit the Compaq Motherboard - Compaq also had the system fan cable run to the Compaq Power Supply, which was the only cooling fan onboard (there are now 3 fans plus the new power supply fan). We do have an XP Home Installation CD, and valid license, so could activate that installation, but am not sure an XP repair installation would help, nor even take with the Compaq version of XP Home already installed. We would also rather not reformat the System Drive and reload all programs, though can if that is the best route. After the rebuild, we tried using True Image in Rescue Mode to restore a fresh image from ext USB to the new system drive, once all data was transferred to external USB HDs, (disconnecting the old system drive before restoring, as suggested), but couldn't get that restored drive to boot...even though TI reported the operation as successful. TI v 9.2323 doesn't seem to have a separate MBR option, so we simply restored the Drive and Single "C" partition (from 100 GB to 40GB EIDE - only 20GB in use for OS and Programs). Next we used Seagate's Drive Transfer utility, to accomplish the drive transfer directly, which did create what seemed to be a functional and bootable system, and bootable MBR, until this morning. Haven't yet tried a full TI restore of the new system drive...would this help, or offer no benefit, since this seems to be both a BIOS and a boot issue? My wife says that at work they now leave their PCs powered on 24/7 - with occasional reboots, would this help skip this cold start issue? Of course, upgrading to another motherboard is always an option, but we are trying to keep this as simple as possible, and would prefer not have to go thru a complete reinstallation of all programs, or replace serviceable parts. Or, he could just boot with the ATI Rescue Disc...if that sounds workable long term to those of you who understand what may be going on here. Regards, [edited] A couple hours later, we found a Compaq document that came with this PC with instructions on how to use their XP Recovery CD to repair the Boot process. It goes on to detail how to use the XP recovery console, to run CHKDSK, using the /r command. Does this repair the MBR, or, would it help to run FIXMBR? Turns out that my friend tried to re-install XP once so there were two installations once, now only one XP Home on the new ATA 100 "C". After which, the system booted normally several times, then, after trying to uninstall AD-AWARE, the system hung at boot again. Several Control+Alt+Deletes later it booted to Windows. So, another mess with various programs and the OS conflicting. Any clues as to why the Acronis Loader can boot cleanly, while the OS flounders? And, in the absence of a clean System Image to restore from, other ways to proceed? Or, do I simply run the Recovery Console again? Any further steps would be welcome, as I hope to leave this PC working smoothly for my friend. And, once these boot issues are resolved, make a good System Drive Image with TI to use should further issues arise. Compaq also suggests removing all devices, then adding them back one at a time. I wonder if the new DVD-RW drive might cause this boot issue, in the secondary position with the original CD-RW as the primary optical drive. Easy enough to check.
