Error loading OS.. hdd failure or Mup.sys?

  1. alrite you guys are my last hope..

    specs are on my sig and profile..

    on thursday nite i was editing a video and exporting it to .mpg for a friend, and like any sort of export i had to leave it on to do its job (few hrs). Checked it again friday morning before i left for uni and it was still going, so i turned off the monitor and left. When i came back to check if it was finished yet i turned on the monitor and out came a plain black screen saying something on the lines of "Error loading OS".

    So as you would do, poped in the winxp cd and boot up to recovery console thinking that either the hdd crashed again (which happend before, fixed by wipeing the partition with xp home and reloaded it again) or got some errors on the hdd.. so first i did a chkdisk /f and it scanned ok so i then typed in dir to get the directory list and it came out with my secondary hdd's contents for C:/. tried to change directory cause (maybe drive letters got mixed somehow), didnt get anywhere, so went into diskpart gui to see what its picking up and i got the 2nd hdd (as C:/), a whole lot of unknowns (which i assumed was the int. card reader). So i turned off etc and unplugged those, turned it back on and went to the cd boot, winxp installer says it cant find any hdd. restarted, went to bios and it dissapeared from the sata list..

    by this stage i was thinking
    a) hdd kaput
    b) hdd had a heat stroke
    c) dust or foreign object (found a dead spider on the bottom of the case.. scary...) caused something to have problem...

    went and got the air compressor and gave it a good clean that was due for a while, and took out the hdd and had a good look, seemed ok, no irregular noises, proceed to boot it outside the case and it spun up, bios picks it up as well and proceeded to load windows and freezes on the win boot screen. restart the pc and went through safe mode with command prompt and it seems to get stuck with mup.sys.

    by now hardware is at basic stage (vid, mobo+sound, hdd, ram, 1 dvd drive). used my laptop to google mup.sys and it mentions something about replaceing it or disabling it through recovery console.. in goes the winxp cd and it does that "inspecting hardware configuration" screen then flashes then nothing. 5 minutes later still blank screen...

    and that is where i'm stumped.

    the hdd has 3 partitions, 1: windows 20gb, 2: applications 30gb, 3: data 137gb. i did forsee windows crashing hence the three part setup for a quick recovery, but i didnt forsee a full hdd faliure, and hope to still be able to fix this short of a full hdd wipe, as like every other pc, has some vital and important data inside with hopes of recovery.. and the sad irony is that i was planning to ghost the data partition that day... (ran out of dvds)

    other maybe usefull info to mention.. case temp hovers between 31`C to 46`C (or maybe a bit more, not too sure) which is kinda normal, thats with an open side pannel. psu turns out to be a no name (or a brand thats called "K"), 320w, although bios sensors give me normal voltages.. although that is soon going to be replaced by a Shaw 500w dual-fan low noise psu

    mup.sys is often blamed, but seldom the culprit. It is the last driver loaded by Windows and that's why it is the last thing you see in the diagnostic startup - usually it is Windows crashing on something completely different.

    then a few questions if i may..

    you say windows crashing on something different? like hardware or what?
    why, when i put the win xp cd in to boot to its installer it just hangs (blank screen) after it checks my system configurations?
    do you think that the hdd is past recovery to cause this?
    do you think that i can repair the drive or at least grab the data off by using some sort of sata->usb hdd case?

    i remember that a minidump did appear sometime in the week before, but since uni and other projects and assingments came up, didnt have time to get it analysed....

    thanks for the info in advance.... :) just need to know what i need to purchase before i go to the shops

    Test your RAM. Test your hard drive.

    Since the HD is SATA, did you load the SATA drivers when you tried the Recovery Console thing?

    Speaking from the experience of yesterday, Sometimes it may be better just to run a repair from the CD if you have absolutely no idea of the cause after a little investigation.

    This may or may not be what you'll end up doing here, but I just thought I'd mention it.

    You might as well go ahead and replace that PSU, at least that variable will be gone. I forgot in your spec, did I see 2X512Mb or 1X1Gb? If 2X512, did you run with 1stick then the other? Did you reseat them/it?

    Have you tried fixmbr from the recovery console? I'm a little fuzzy whether or not you can stay up long enough in the Recovery console, excuse my stupidity.

    well psu will have to wait untill teusday when i have a day off uni, but im sure it should be able to handle barebones system for now..

    as far as i remember with reformatting/reinstalling the windows partition (crash, spring clean etc) 3 times before - tho hadn't have much trouble since my last format, installed windows without any need of SATA drivers, since i dont use RAID nor does my mobo support it which maybe the reason why it lets me off...

    its 2x 512 ram, although i cant remember if it was ddr or sdram, just that its brand is Geil or something along those lines (blue metalic/alloy case). i think they're high quality (at the time), the last time i ran memtest it passed with flying colours, but that was a while ago.. i will try to run with one stick and reseat em and see if it makes any difference..

    but what i am trying to say is that i pop in the windows xp cd, it boots from it etc.. and the screen before it goes into the blue "windows installer" screen it checks my hardware, then nothing, no windows installer (and meaning no recovery console) just a black screen.. if i could get into it i would have done a repair or some sorts already...

    Alright. i pulled out a spare IDE hdd from one of the other pcs here and managed to load it with winxp. so the cd works.

    conclusion: hdd is stopping windows to load, including the windows setup disc....

    Now i am in the market for one of those external hdd case for sata + ide with usb 2.0 or firewire.. any suggestions?

    oh yeh.. whats better for psu brands:
    Shaw or Coolermaster?

    Edit: well now i got a windows system up and running (bare system, no updates yet), i tried pluging in the sata hdd back into the mobo, and first time the bios picks it up, but when i restart the pc (after exiting bios of course) it dissapears... even at my computer/disk management.. do you guys think i still have a chance off pulling some of its data off via a external hdd case? its got 3 partitions with the biggest 137gb...

    ok.. well my thing is solved, although now i start to think this should be moved to HDD's section of the forum...

    so yeh, my system is up and running with a new hdd (W.D 160GB SATA), gonna send the seagate hdd back for an RMA and am considering their data recovery service to get files back...

    turns out this hdd is dead (I/O error) even when connected through an external hdd case...

    Moral of the story: Ghost as soon as you buy the software.. and dont forget to backup regularly...
