Windows 10 fail to boot with 0xc0000001 messeage

Q: Windows 10 fail to boot with 0xc0000001 messeage


Hello, I'm running multiboot installation on machine with UEFI. I have Windows 10 and Ubuntu installed managed by Grub at startup and I have laptop working like this for about half a year. By the time... I'm using Windows 10 very rarely I rather
use linux for my everyday work. But yesterday I need to, and very disturbing BSOD appeared.


Your PC couldn't start properly

A required device isn't connected or can't be acessed

Error code 0xc0000001

I cannot log into safe mode. System just hangs at the boot screen and shutdown laptop itself after couple of minutes.

I haven't made any hardware changes ever.I haven't made any driver changes.I do not mess up with any Windows directory but I have Windows partition mounted in Ubuntu.I do not mess up with EFI partition recently.Last time I have using Windows installation is about 2 weeks ago.System sometimes instead of showing BSOD is hanging at the boot screen.

I have googling for fixes fo hours. So I made USB with my Windows 10 installation (exactly the same from which I have Windows installed) and run Windows Recovery Envoirnemt. My laptop is hp 8560w.

Fixes and failures

Restore default settings in firmware setting (aka BIOS) - nothing changes

Windows Recovery Environment

System restore

I got message. "To use System Restore, you must specify which Windows Installation to restore. Restart this computer, select an Operating System and then select System Restore."

Automatic repair

Fails - with no information in event log.

Reset your pc

I got message. "The drive where Windows is installed is locked. Unlock the drive and try again."

Windows Command Prompt

S: is my EFI partition

chkdsk c: /f /v /r /b /offlinescanandfix

no problems found

sfc /scannow /offbootdir=*s:\ /offwindir=c:\windows

I got message "there is a system repair pending which requires reboot to complete. Restart windows and run sfc again"

Bootrec /fixmbr - nothing changes

Bootrec /fixboot - nothing changes

Bootrec /scanos - windows found

Bootrec /rebuildbcd - message "The requested system device cannot be found."

del s:\* /s /q

bcdboot c:\windows /s s: /f UEFI

nothing changes

I even format EFI partition and make it again.


Ubuntu still works fine so AFAIK it's not hard drive or GPT issue.

I can't login to recovery mode by Shift + F8 but I had never could. So I don't think it matters especially that fixing by Windows Recovery Mode from USB work neither.

It seems to be ridicolous for me that Microsoft provide not even detail but in fact any useful information about why system fail to boot.

Pleas do not tell me to contact hp support because I really doubt that they help me.

Preferred Solution: Windows 10 fail to boot with 0xc0000001 messeage

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)


   Evidently while trying to take advantage of the Windows 10 Upgrade, somehow some damage was done to a file(s) from my old  Windows 8.1 OS pertaining to a missing, or damaged, file....  \windows\system32\boot\winload.exe  ...  which
in turn rewflects an Error code:  0xc0000001...
  At any rate, as a result, I am not able to boot up without an installation disc, nor perform the requested "Restart" to continue with the Windows 8.1 reinstallation because of this Error, and missing file(s), and am at my wits end...
  Please does anyone have any idea what my best course of action might be at this point, as I have seeminglly tried everything that I could think of for the better part of two weeks now.
  Last night a gal that lives a few doors down checked in on me, because she hadn't seen me for those two weeks and was just pretty concerned about whether I was allright or not, and she suggested that I take the laptop to an outside Technician, but
unfortunately, I am a disabled  U.S. Veteran, and I just don't have alot of money to work with.
  If someone could please help me with this litlle bit of a predicament, I would surely appreciate it more than you could ever know.
  Thank you....  And I Wish you Happy Holidays!

Hi All,

I'm running into a significant amount of trouble trying to re-install my copy of Windows 7 Professional (x64). I recieved my new Dell Studio 1557 yesterday, and was installing all my new software etc only to be met with a various and (pretty much) unsolvable blue screen error about 12 hours into the process.

Anyway, after an agonising few hours on the phone with Dell Customer Support, they suggested that I do a clean/manual install of the O/S from the Boot Disk I was provided.

I have attempted to do this several times now, selecting F12 as the computer restarts and choosing to boot from CD/DVD drive. However, each time I am met with this error:


FILE: \windows\system32\boot\winload.exe

"The selected entry could not be loaded..."

Would copying the boot CD contents to a USB HDD, then booting from there help?

If anyone is able to help me out with this, that would be fantastic. It's so frustrating that I just bought a new system, and already it's died!!!!



A:Dell Windows 7 Boot Disk will not function (0xc0000001)


Sounds like you got a bad installation disc. That would explain your first problem too.

I would recommend contacting Dell and having them send you new installation discs.

You can try creating a USB installation key first if you like. It certainly can't hurt. Be sure to read this tutorial: USB Windows 7 Installation Key Drive - Create

From my Windows Boot Manager It stated that Windows failed to start. A recent hardware or software change might be the cause. My problem started after I went to the
https://www.healthcare.gov/glossary/affordable-care-act , and my google chrome requested that I kill the website for inactivity. It asked me 3 times. I told it to wait twice and the third time the program froze
and would not let me close it. I disconnected my laptop from power including the removal from of the battery. This shut it down and stopped the connection. When I restarted the computer, I checked to see if anything had affected the bios, and it did not, until
I tried to restart the OS. Then I received the message from the Windows Boot Manager. I have tried repair, and reformat the hard-drive to no effect. I wanted to find out why the affordable care act would require the use of a

Hello everyone,

After my HP pavilion g6 crashed the other day, I bought a new and upgraded hard disk, Samsung 830 SSD.

Had not burned the HP recovery discs, so I downloaded and ISO with Windows 7 to be able to boot the computer.

The HP won't boot:

Windows failed to start.
File: \windows\system32\boot\winload.exe
Status: 0xc0000001
Info: The selected entry could not be loaded because the application is missing or corrupt.

The ISO dvd is fine, I checked it on another computer.

I ave been searching a dozen of fora but so far with no luck.

Could somebody point me in the right direction? Any help is welcome and much appreciated.

Greetings from DK,

Did you get the ISO from here. Official Windows 7 SP1 ISO from Digital River ? My Digital Life This is the only place I would recommend. Burn it at 4X and make sure you have the same version as what was on there before.

core i7, 16 GB, 120GB SSD, 2TB HD, radeon graphic, MSI mobo Win 10 up from 8.1.

Rather perplexing boot problem. I use my computer fine, turn it off. Next day I can't boot. You get the screen that takes you to the screen with the 8 options (safe mode, safe mode w networking, boot logging, etc) but no matter which option you choose, you wind up back at the same screen - can't boot.

I said to myself, no problem. I had cloned my SSD with the OS earlier when it was working fine just for these situations. I put the clone in, access the boot option, and boot from the clone and FUDGE! still doesn't boot.

I put in my 8.1 OS disk, (since I upgraded there is no win 10 disk) get to advanced options, rolled back to a sys restore date when it was working fine. No go - still can't boot. What good is it to have this stupid feature if it doesn't work ?!!!!

So I go to advanced options again, and try the command line. Ran bootrec with various options to rebuild the boot record and MBR, etc. They all say completed successfully, still no go - can't boot.

I've run that dism command, but it just aborts with errors.

previously, I'd run separate disk utilities to check my SSD that has the OS on it, and it showed no errors.

I'd also periodically ran anti-virus (avira) and MB anti-malware. They either never found anything, or they just found mildly annoying things, but no serious problems.

Have you tried resetting the bios to "optimum defaults"? At the bottom of the options you see i.e. Safe Mode etc.....do you see "Repair My Computer"? If yes go in and try "Startup Repair". The other thing I would do is boot to Safe Mode with Networking and then "Run", cmd, from "c" prompt "chkdsk /r" and run checkdisk on the hard drive by agreeing "Y" to mount drive or "Y" to approve run on restart.

HP Pavilion 15 originally on Windows 8.1, had been upgraded to Windows 10.  Failing to boot.Would not boot into safe mode.Had tried all manner of recovery options including the built in Factory restore options and still would not complete the boot sequence.Decided the restore image must have been faulty.  With nothing on importance on the disk, was able to successfully install Windows 7 and boot.With the laptop completing the HP built in diagnostics, I bought the restore disks from HP.Have just run these through, having first reset the BIOS to defaults and after installing all the required data and following all the prompts, it still won't boot.Unit is not under warranty.  Have now replaced the HDD and run the restore disks from HP again, same problem.I can get it to a state where it gives me the 0xc0000001 error and tells me that after multiple failed attempts to boot, I must boot from a windows disk and try other means to repair the install.Help?

An old HP Pavilion 32 bit Vista A6000 began giving me 'Header checksum does not match the computer checksum' errors. I inserted my 32 bit Vista disk and performed a Startup Repair. All was good.

I ran Windows Update until it was current, ran Malwarebytes, TDSSKiller, Hitman Pro 3, ADWCleaner and JRT, correcting any errors I found. The computer ran beautifully for 5 days, and it was rebooted at least a dozen times over those 5 days. Then I didn't use it for a day...

Today I get the black screen with white lettering pointing to a file in Windows\System32\Drivers\Tcpip.sys with a status code of 0xc0000221, and am prompted to use my Windows disk.

Starting it with the same disk I'd used before, I get the 'press any key to boot from CD', I see it loading files, then I get another black screen pointing me to Windows\System32\Boot\Winload.exe with a staus code of 0xc0000001. Subsequent efforts will sometimes give me the same file, but a status of 0xc0000221 (same status as I'm getting with a normal boot), always telling me to use my install disk. Duhhh... I am using a disk - the same disk that let me fix the checksum problem.

Anyone have any ideas?

To Whom It May Concern:
Long story short:
My son has a Win 8.1 notebook ASUS model: R500VJ . I asked him to make a recovery disk when he bought it, but alas, he did not listen to his dad. Anyway, here is the message:

your PC couldn't start properly
after multiple tries, the operating system on your PC failed to start, so it needs to be repaired.
error code: 0xc0000001
you'll need to use the recovery tools on your installation media. If you don't have any installation media, contact your system administrator
What should I do?

Thank you in advance,
David Durbin

A:PC wont boot...error code: 0xc0000001

Contact Asus to see if you can purchase recovery media (I've been told that they stopped providing recovery media).
If not available from them, then purchase it elsewhere.

FWIW - you can create a repair USB drive from any Win8.1 system.
Don't bother copying the recovery partition as it likely won't work on the Asus
You won't be able to reinstall Windows with this (unless you can access the RESET function through the tools), but you will be able to run the different repair functions.

I suspect a problem with the hard drive when I see an error of 0xc0000001 - but that's just a guess on my part.

Hi there,

I've recently built a new rig and I've had continuous problems trying to boot. I have two HDDs and one SDD. It seems when the two HDDs are plugged in, i can sometimes boot ok, and most times i get:

Windows failed to start. A recent hardware or software change might be the cause.

Status: 0xc000000e

Boot selection failed because a required device is inaccessible


Please select a boot device, or something to the affect.

I've updated to the latest bios on my new mobo ( Gigabyte z97x SOC Force ) and ive done a fresh install of windows several times on the SDD. I also ran crystal disk to check health on the SDD and it came back healthy.

It seems mostly my boot problems are linked to plugging in the two other HDDs, though I've no idea why this would be, and how to fix it? Is it a motherboard problem or a HDD problem?

Any help greatly appreciated.

Friend of mine gave me her Acer Aspire 5742z-4813 because it fails to boot and eventually asks to repair, which it doesn't. Can't enter safe-mode, either.

Only thing she's said is that her daughter installed Norton 360 a few days before it crashed.

Things I've tried:

At command prompt, ran the following with no effect: bootrec.exe /FixMbr, bootrec.exe /FixBoot, bootrec.exe /RebuildBcd, chkdsk /f E:, and finally chkskd /f /r /x.

I also entered BIOS and changed HDD mode to IDE from ACHI. No joy.

I'll try to make sense of this to you. My computer has been working great until last night. Today, it bricked on me.
Last night and until a out noon today, I was seeing occasional corruption of the image on screen (strange blocking/pixellation like a bad hd tv picture). I started getting locking-up freezes, which I could sort of unfreeze with ctrl-alt-del. This happened frequently while browsing the net las night (oddly games worked fine).
Today at one point the whole image started flickering/fluctuating up and down and then the image scrambled totally and was locked-up, so I hard reset.
Upon restart, bootup fails. Chkdsk, memory scan (from startup repAir and the installation disk), image and system recovery fail. When I read the detailed results from start up recovery, it tells me that no drive is present.
So, did the drive fail, or maybe it came unplugged inside the tower (unlikely bc the tower hasnt moved). Or, did intel smart response technology screw up and the cache is screwed and it's messing up the primary drive it accelerates? Windows 7 64-bit OS on z68 mobo with 64gb SSd accelerating 500gb primary.
Any insight is VEry greatly appreciated, as I'm stuck working off my iPod touch for troubleshooting.

Hello, sorry for my english but This forum is probably the last thing that could help me.
I rode other topics about this problem. When I start computer it stops right before "Starting Windows" and there is only a black screen. I cant start windows any way.
So i put a disc with windows and try to repair but it said: "there is no problem with windows starting"
Than I started a console and try to insert c: and then
bootrec /fixmbr and fixboot
but fixboot doesn't work - I dont remember literally but it said something like: there is no filesystem/wrong filesystem

when i try to scanos it say that there is 0 operating systems.

Then I tried to run gparted to flag a disc, but it showed me different partitions configuration then ive got on windows - there is no windows disc!

oo.. i tried also to build BCD but when i had to put command: cd boot it said there is no comand like that

Please help me... I dont want to make a format...

Recently I just tried starting my computer on and it wouldn't boot.

I left my computer in locked mode then it eventually went to sleep.

I kept trying to restart it and had no luck, I checked inside the cpu was running and the dvd drive was still able to open and close. My USB mouse or keyboard weren't powering on though neither was my monitor showing anything I didn't hear any beeps. So I kept disconnecting the power outlet from the wall since that's the only way I could restart it.

Eventually it came back and I got startup repair opening by itself
That's what I got from the error.

Here are my computer specs
400 Corsair PSU
4GB Memory
AMD Phenom II x4
GIGABYTE GA-MA78GPM-UD2H AM3/AM2 with ATI Radeon HD 3200 onboard GPU
Windows 7 Build 7100 64 Bit

Eventually the system started backup fine after going through startup repair. All my files still there.

If it matters I was using the onboard graphics having one monitor running in VGA and the hdmi connecting to my tv.

I will try to sum this up a bit..
I have Windows 7 64-Bit, and about a month ago I was having problems booting.. I went straight to safe mode and was able to use Diagnostic Startup from MSConfig.. The machine booted fine and I was able to get in and run virus scans. Nothing was found using AVG, Ad Aware and other programs.. So I thought well lets try Limited Startup and that worked! So I downloaded a few registry cleaners and what ever else I thought I might need.. I ran all the scans I could think of.

So then I decided lets try full startup and that was not a good idea.. I now get hung just after the Windows Logo screen before the Login Screen.. Actually I have made it to the Windows Login Screen a few times and put in my password but it says windows starting and then windows shutting down..

I can not get into safemode now either as it will hang with the last line showing "avgdisha.sys" So I goodled that and I get a response from AVG claiming they screwed up the Windows 7 64Bit edition with their latest upgrade. They put out a CD to help wipe out whatever the issue is, but my computer has wireless internet so the CD didn't seem to want to do anything..

So now I have a partition of Win 7 but it is not getting recognized. Is there any way to help this?

Alright guys, this is gonna be a fun one.

I bought a new AMD AM3+ 8 core processor and Asrock mobo from Microcenter tonight, got home and stripped the old outdated Intel gear, for the AMD.

I've got all of my AMD setup wires tucked neatly, get it to it's bay, turn it on and fail..
It boots past the BIOS okay, and starts Windows loading screen, but about 20 seconds in screen goes black, and it starts the whole process over again. Same deal with trying to boot in safe mode.

I feel like I'm in deep now and didn't research enough before trying to make a big change. Probably a driver issue that i'm experiencing.

Any suggestions? I would really hate to put my old mobo back in, just so I can go and uninstall mobo drivers.

You can however try the Repair Install method to see if you could save the existing copy of Windows but may likely run into any number of possible problems between lingering device drivers for hardwares and chipset no longer seen as well as other things!

The best practical advice anyone can give you for this however is still to see a Clean Install Windows 7

I had to do a clean install of Windows 7, because while trying to fix dual boot with Windows 8 problem, after I no longer wanted dual boot with Windows 8. My main HDD failed, I had to install another HDD, tested it, checked good, I then installed Windows 7 on it, also I used other software and erased everything from the drive that had Windows 8 installed on it.
After installing Windows 7, found that my computer won't bnoot with out Windows 7 install DVD in my dvd drive. The boot order is (1-dvdrooom, (2-First HDD), the first HDD has Windows 7 installed on it. When I try to boot computer with out install dvd in drive, it displays this at bottom of screen,

I shut down my computer, restart it insert dvd into drive and let it boot into windows, and then everything is ok. After Windows 7 finished booting I went into MsConfig, then clicked the Boot Tab and this it what is there, I am including a screen shot of MsConfig.
This is the first time this has happened, and first time I have ever encountered this. I am not sure how to proceed to fix this problem. Please help, as this has really gotten me frustrated. Thank you.

I've installed Ubuntu 11.04 on my notebook ASUS U36SD. It worked perfectly fine for 4 months.
Recently, I decided to install the last version of Ubuntu, 11.11. From now, Windows 7 doen't want to boot: It freezes at the boot screen. I tried to use the repair mode, but it failed. I also tried the safe mode. It still does't boot and freeze when loading CLASSPNP.SYS.

Please, do you have an idea about how to solve this problem?

A:Windows 7 fail to boot after ubuntu installation

After an installation of ubuntu, my C: partition, where Windows 7 is installed is corrupted.
From linux, I can read it and access the disk, but the windows recovery environment doen't detect it.

I think that it is because my partition is also hidden (0x17)
Do you know how to unhide this partition from linux, or to make a chkdsk on it from the recovery environment?

Had Windows 8.1, attempted upgrade to Windows 10, upgrade failed.  Laptop won't boot.  Getting error that Interwebs indicates is an AVG anti-virus issue with W10 upgrade.  AVG recommendation is to rename avg system files and try boot again.  I can't access the file system of the hard drive to make the changes to the files.  Also, I would like to access the file system to backup the existing data files.
Long story below....
Lenovo G580 laptop.
Was running Windows 8.1.
Upgrade to Windows 10 attempted.  I wasn't there for this part but I was told the laptop took a long time and rebooted a few times but then eventually it comes up to this error:

A:Windows 8.1 to 10 upgrade fail; No boot; avgidsha.sys

Hey...  I was able to access the drive when connected via the USB hard drive cradle on the latest version of Ubuntu.  The older version of Ubuntu only showed the drive but gave me no options to access it.
It appears that the drive might be failing.  I was able to copy the data I wanted.  I was also able to modify the avg system files as directed in the AVG support link provided in my previous post.  However, the system will still not boot.  Now it gets me back to essentially the same place as before but now it balks at file avgboot.sys or something like that.  However, this file was renamed in the earlier step, so I'm not sure what is going on there.
Anyway, I got my data and suspect the drive is failing, so I'm just going to replace the drive and install Windows 10 fresh.

So yesterday I installed Windows 7 on a laptop, there wasnt enough room for an upgrade so did a new install. The install went find until I had to enter information, Name, password, internet settings etc.
Here a red cross came on the screen and the laptop crashed
When the laptop restarted nothing happened. It went to a black screen and there is a a flashing underscore _ in the top right hand corner. that is it.
I can access the boot menu but cant boot from either hard drive installed in the computer which makes me think its an IDE cable fail. I can basically only boot from disc which just tries to make me install Windows 7 again and none of the repair options work. But if it lets me install windows to hard drive again it cant be an IDE fail surely? I need help ASAP

I would go to the manufacturers website of the make of hard drive you have. Download their harddrive diagnostic tool or, use a third party one to test your hard drive. If all goes well you may have a bad copy of Windows. Might be a corrupted file on the disk or bad disk.

alright, so i had an issue with deleting a steam folder that was corrupted. after googling a while i learned i should run chkdsk (checkdisk) when you rightclick on your hdd 'properties, under tools tab' etc.

so after that i just rebooted my pc and everything was normal, i could delete the folder. then i got a few windows updates, which i just ran. and rebooted normally. after a while, surfing a bit, then playing a videogame, my computer just crashed with bluescreen.

ever since then i couldnt boot up my pc normally again.
i do manage to get the BIOS screen, then the windows logo 'loading', but then it just gets me a blue screen again.

so the errors on the blue screen im getting is:

and something along these lines:
STOP: 0x0000007E
(0xFFFFFFFFC000000S , 0xFFFFF88000E0DE3A, 0XFFFFF880009A8B78, 0xFFFFF880009A83D0)

it might be worth mentioning i had intel rapid storage techonlogy, which uses an ssd for caching. i thought this was the problem, and removed the ssd but no results.

Hi guys I have just had my computer in for repairs and the ssd disk was changed. I was running windows 10 before and everything was perfect until an update ruined it all. Long story wont go into that  Anyway so i unstall all my software and do an update to windows 10. All the preps and so seems to go fine. Then it reboots and is stuck. Never moves. I see faint HDD activity but i let it run for 8 hours and still nothing, still gangs in the acer boot window. It is after the bios load, because i can access that if i am fast and press f2. After a while i gave up and thought perhaps it was just a fluke so i used my recovery dvd's and reinstalled my system and office and outlook and .... After about 5 hours installation my system was ready to go. So i decided lets try again. And yet again same failure. Simply hangs with the Acer Logo. I called Microsoft and the told me to do a startup repair. However that is not possible, i can get it into the repair mode but none of the functions work. So they said it was a hardware thing but everywhere i look it states the v3-772 should have no problem with the windows 10. I am normally quite good at fixing my own problems but in order to fix a problem i need an error or errorcode or something to go from. Does anyone have any idea what to do?

Thanks for looking.

This problem has been driving me crazy, presumably since I got the SSD, 'though since I mostly suspend the computer, I wouldn't have noticed initially, which is why it took me so long to narrow it down.

The issue is as the title describes, but here are more details:
The computer will receive power.The BIOS and OS become unavailable, intermittently. (no display on either, 'though it wakes the monitors)The HDD light flashes only a few times.The displays come on from their suspend modes.I've tried resetting the BIOS.I've flashed the BIOS; it's current and making no difference.Having the USB devices in or out makes no difference to the problem.I've checked the RAM, using different DIMMs and different lanes?no difference.I've scoured the BIOS settings a number of times and cannot find anything out of place.Windows 8.1 boots perfectly fine as well. (provided AHCI mode is enabled in the BIOS)Suspending in Windows always works; it seems to entirely get around this issue.I have no speaker, so I cannot report beep codes.

Welcome to ideas, 'though I fear I've tried it already. However! The reason I've said it's the SSD, is due to what I've just now experienced: I unplugged the SSD, and it booted up just fine, minus an OS, but once I plugged the SSD in again, it booted up, on par with what I had previously done as a temporary "fix".

Until now, I've had to unplug one or a few of my SATA cables from the motherboard (doesn't matter which socket the SSD i... Read more

Hey guys.

I run a WinXP with SP 3.

My computer has been running fine until yesterday when I got a couple of error pop ups, which I clicked by fast, followed by a bluescreen. I restarted my machine and now WinXP can't boot. It gets to the loading screen, but when the loading is done, the computer just restarts itself. Then i'm prompted to chose if I want to start windows in fail safe mode. In fail safe mode everything runs fine. I ran through my computer with Kaspersky once, then once with Avast. Also I ran it through once with Anti-Malware Bytes. All done in fail safe mode, but with no results.

I got prompted to use WinXP system restore when into fail safe mode. But apparently I have no old configurations from a past date to use!

I turned off auto reboot to be able to see the error message, and I got the following:

STOP: 0x0000008E (0xC0000005, 0xB9F92091, OxBACC7384, 0x00000000)

k71.sys - Adress B9F92091 base at B9F90000, Datestamp 48849e41

I still can't get windows to work normaly, i'm writing this in fail safe mode. I'm not really sure what to do from here. It's very frustrating!

Any help would be much appreciated, thanks!

Hello really need your help as i have hit a brick wall.

My new build with windows 8.1 installs fine but keeps crashing not even long enough to create account.

The specs for my pc are:

AMD A8-6600k 3.90GHz
TeamGroup Vulcan ORANGE 8gb (2 x 4gb)
Gigabyte F2A88XM-HD3 AMD 88X
Kingston 120gb SSD
Superflower 300w Power Supply

When i first installed windows it worked for an hour or two then crashed, but now keeps crashing after minutes, and get the error code 0xc0000001 on startup.

Heres what i have tried so far:

Reinstalled windows 8.1 on same ssd and also tried it installed on a different HDD
Made sure cpu was correctly seated and checked everything is correctly connected.
Swapped RAM for another set which i know works from another computer
Flashed Bios to latest version
Run a cpu stress tests using UBCD which gave no errors
even tried installing windows 7 which still does the same

The pc never crashes in bios or when using UBCD.

Theres nothing more i can think of to try so would really appreciate any suggestions?

I presume you have installed the correct drivers from the device manufacturers. Have you tested for a defective component in the system? Mismatched RAM sticks can cause problems also.

You could also do a stress test, see this site:

In order to access the Windows Dump files, you can do the following :-

1. Download Ubuntu ISO file from the official sources and install it on a PenDrive/FlashDrive.
2. Boot the laptop using the Pendrive. Incase it is not booting via the Pendrive, make sure that on opening the Boot Manager, the priority for the Flash Drive is set at topmost.
3. Once, you are given the option to either Try or Install Ubuntu, click on Try.
4. Open the Explorer in Linux and browse in the default installation directory of your laptop.
5. Goto C:/Windows/MiniDump/
6. In the trial mode of linux, you can do almost everything so connect to Internet and upload the dump files here after zipping them up.

Let me know incase any further help is needed
