BSOD's After Hardware & Operating System Upgrade

Q: BSOD's After Hardware & Operating System Upgrade

I recently upgraded my system's graphics card and processor to an FX 6300 with an R7 250X. I had some issues with my old OS, so I upgraded to Windows 8.1 Pro.

After these upgrades, I'm now getting various different BSOD's (Blue screen of death) upon boot and while using the machine. For example, NTFS_FileSystem_Error, Kernel_security_check_failure and several more which I cannot remember off the top of my head.

In addition to that, I get error messages on start-up for various different programs, sometimes Google Chrome fails to launch, and I'm unable to use any of the Windows Metro apps - they simply launch and then crash.
Iv'e got all the latest drivers, I've ran an HHD check within windows, and a RAM test using memtest86 and nothing abnormal was found. I can play games when I'm not getting BSOD's at solid FPS, which shows me that all of my new hardware is not at fault.
It's getting to the stage where I'm considering downgrading to Windows 7 again.

I'd appreciate any help that I can get on this. Thanks in advance. I can post anything else that would help you guys out with troubleshooting.

**System Specifications:**
Gigabyte GA-73LMT USB3 Motherboard.
AMD FX 6300 Hex-Core @ 3.5 Ghz.
Windows 8.1 Pro.
Sapphire R7 250X 1GB GDDR3.
8GB Corsair RAM (2x4)
Seagate Barracuda 1TB HDD.
Generic 500Watt PSU (Maybe the cause...)

USB peripherals disconnected.
On first startup go into the BIOS, check settings
and make sure CD Rom is set as 1st boot drive.
Restart computer with xp pro cd in cd rom drive,
and follow setup instructions.
Install SP2
Install MOBO drivers then other hardware drivers.

Edited Update: Since I never have owned a Dell or ever worked on one I was not aware of their built-in partition for hard ware diagnostics. As the system boot ups up just keep tapping F12. it ran all tests and everything passed -- except the Western Digital hard drive. It failed both the Short and Long DST. Now for the joy of putting in a new drive in system that is about the size of my car's glove compartment. :/
Can this be done? Here is the issue: My sister brought me her Dell Inspiron streamline 660S (manufactured 2012) and told me that her operating system has totally disappeared. Dell told her it was due to a virus and that the hard drive was probably damaged and she needed a new one. Her company's IT department did a diagnostics and said the operating system was not present.

When I started the computer up, it went to a blue screen and said there was an error with nostkrnl.exe (parts corrupt or missing) and error 0x0000185 which is a very serious issue.

It gave me 3 options:

Enter to try again
F8 to enter set-up
Esc for UEFI Firmware.

The first is a no go and the F8 is also not possible. Under the UEFI the system's BIOS is keeping the date and time correct but nothing else can be done.

The system was installed with Windows 8 and was a gift from her fiance. There was no Windows installation disk that came with it but she will be sending me the disc with drivers and utilities.

I'm not sure if this is in the right place because my problem covers many areas it seems so I apologize if I'm in the wrong place.
Yesterday morning my boyfriend gave my his old graphics card, a GTX 760, I made sure everything was compatible with my hardware before installing it. I uninstalled my AMD drivers, I had an AMD r7 250x, and shut my computer down, popped it open, and carefully changed the cards. I made sure not to knock anything or any cables, put it back together and booted it up.
I got a screen with a frown face, im not sure if this is the BSOD on Windows 10, I only had Windows 10 for a couple days, and it restarted my computer. I tried switching the graphics cards back thinking that was the problem but once I turned my computer on it said it couldn't find the operating system, I've gotten a handful of errors since then, most have to do with not having a proper boot device or not being able to find the operating system.
Here are the things I've tried:
Using a Windows 7 install disk
Using an old backup restore disk I made when I had Windows 7
Creating a restore drive on another Windows 10 computer on a USB
Unplugging, leaving it for a little bit 10-15 min, and plugging it back in
Changing the graphics cards
Opened up the computer to double check the wires, all is plugged the way it's supposed to be
Upon going into my BIOS menu, I discovered it is reading that my hard drive is connected but it wasn't in the boot priority list, so to fix that I disabled all boot pr... Read more

This is a new laptop, as yet unused, still in its original packaging. The laptop has installed Windows 8, which I would like to upgrade to Windows 10. This should be easy enough, as I've already performed the upgrade to Windows 10 on my desktop computer without any problem. However, before doing anything to this new machine, I'd also like to add a second operating system, Windows 7, to the same hard drive, and would be very grateful if anyone reading this post could explain, in very simple terms, how I would go about doing this.

Helping a friend on his Acer Aspire V5 laptop that was running an OEM Windows 8 to upgrade to 8.1.

After selecting the Upgrade to Windows 8.1 via the store, the system went through it's install procedure, however after it does an auto reboot, it gives you a blank screen with the message No Operating System found, in the upper left corner.

But, you can turn the machine off and back on, and it will boot just fine. However if you select restart it does the same thing "no operating system found", on restart and again you must power down and power back on.

I have searched for fixes, but all seem to point to some sort of re-install process. I am not to crazy about the idea of re-installing to factory settings or doing a repair back to Windows 8 and attempting to upgrade again, are their any known shorter fixes for this?

And if I do go back to Windows 8, and try to upgrade again, what is to say it won't happen again?

I hope this will help all the other user out there struggling to get their M.2 ssd to work with their HP Envy 17 laptops. I will give a step by step instructions on how to install and how allow the bios to recognize the m.2 ssd in slot 0, and how to install or run windows 10 off your m.2 ssd. 1. Download the latest updates from HP Envy from HP - I used Internet Download manager to download all the updates as of June 15, 2016. (Bios, drivers, software) http://support.hp.com/us-en/drivers 2. Install your M.2 ssd Boot into Windows - Right click on My Computer on your desktop and select Disk Management, and  Format Disk 0 If you want to do a clean install and you did not update your HP ENVY with the latest software and drivers this is the screen you will see when you try to intall Windows 10 on your m.2 ssd. The bios will not see the m.2 and will not allow you to select it in BOOT options.  Instead of doing a clean install, I highly recommend using the Samsung migrations software, it will clone your DISK 1 (2tb hard drive) to Disk 0 (m.2 ssd). After successfully migrating your Drive C to your M.2, when you reboot your m.2 ssd should kick in. Right click on My Computer on your desktop and select Disk Management, you will notice now that Drive 1 is offline, it will conflict with your m.2 ssd drive, don't worry, you can right click on disk one and select go online, you can then start to delete main partition, I have not yet figu...

Hi, I'm in need of figuring out if my laptop was infected by a trojan, the operating system went kapoot and i need to reinstall it, or if its hardware failure. I used it last night and my AVG caught a "small trojan horse" called cryptbase.dll and after removing it i believe is where it began. My computer restarted and ended up starting up with the acer splash with me able to click f2 for setup. But f8 doesn't work and causes a long beeping noise if i leave it alone it goes to a black screen with a underscore blinking at the top left. i've done some research but, im unsure which route to take without taking some advice for my own laptop. My laptop is a Acer Aspire 5741-3541, Windows 7,intel core i5-450 processor, 4 GB DDR memory, 500 GB HDD. if you need more information please ask because im unsure with what is needed to fix the problem.

I have a Lenovo U350 laptop. Windows 7 64bit.
I had a blue screen yesterday night.
I turned off the computer and went to sleep.
I tried to turn on my comp this morning and below the copyright info I get:
PXE-E61: Media test failure, check cable
PXE-MOF: Exiting Broadcom PXE ROM.
Operating System not found.
Here's what I tried so far:
I went in BIOS and restore defaults. (I noticed in main BIOS HDD Status: None)
I check the hard drive to make sure it wasn't loose.
I booted from an old Bart disk I had to see if I could do something
in CMD. But it won't let me go to the c drive, just d.
I don't remember if I could do anything in d. 
I remember having booting issues in the past with other computers and I would just boot from my Bart disk
and I remember everything working fine after. I just can't remember the commands.
I tried to access this one key rescue system I read about in my Lenovo user guide to see if I can do something
from there. But when I press the key for it  my comp goes to the operating system not found screen.
Usually when the computer doesn't have proper shutoff, the next time I turn it on, the screen that allows me to start in safe mode or the other modes pop up. But that didn't happen. So I tried to access safe mode manually and nothing, just goes to the operating system not found screen. 
I don't have my hard drive backed up so I know I'm probably screwed if it's my hard drive.

First off, I'm a total noob so you might need to explain in step by step format when there is something you want me to try to solve this issue.

I recently upgraded my desktop by buying a new motherboard, cpu and a ram kit. After changing the hardware I booted up (without formating and reinstalling windows) and installed some of the software (drivers + CPU-Z and some other stuff) that came with the motherboard, and then i started getting bsods. First i used the "SET DEVMGR_SHOW_NONPRESENT_DEVICES=1" so i could see the drivers for the old hardware and i uninstalled that, but i still kept getting bsods, so i tried to run a windows memory diagnosis and it said that everything was fine. But i still kept getting bsods, so i tried "sfc /scannow" and got the message:

"[SR] Verify and Repair Transaction completed. All files and registry keys listed in this transaction have been successfully repaired"

and it didn't fix a thing. So i tried "Dism /Online /Cleanup-Image /RestoreHealth" and got the message:

"The restore operation completed successfully. The component store corruption was repaired. The operation completed successfully"

but the issue still remains unsolved and i still get bsods. This might just be a coincidence but it seems to only happen when i watch video on youtube or twitch (i almost always do that tho, so might have nothing to do with the issue).

I then loaded a 1080p youtube video and let it play for about 5h, sopped because of an add that wouldn't load while i was sleeping, no bsod. Then i tried showing a 1080p youtube video on full screen on both of my screens (dual monitor, same video but in different browser windows) and i then finally got a bsod, got bsod by doing this 3 more times, takes anywhere from 5 to 45 min for it to happen. So i can now force the bsod, but since I'm a noob i still have no idea of what is causing it..

So for the longest time I was on my Bloomfield i7 920 processor and with a sale on newegg for the new Haswell i7 4770k I decided to take the plunge and upgrade.

I reformatted my SSD and reinstalled everything, however ever since, I have been getting BSODs almost every day. Sometimes it is the KMODE_EXCEPTION_NOT_HANDLED message, but mostly it is the IRQL_NOT_LESS_OR_EQUAL message. It has happened in all circumstances, be it active gaming, active web browsing, or an idle state with just a web browser left open (meaning I left the computer on, went downstairs to water plants, and came back to a rebooted machine 15 minutes later, with power savings features disabled).

Processor: i7 4770k
Mobo: Asus Z87-Pro
GFX: EVGA GTX 560 2gb
PSU: Corsair TX750

All the motherboard drivers are up to date, and the motherboard released a BIOS update which I installed, to still continue to see BSODs before and after the update.

Everything worked perfectly fine before the hardware upgrade, so hopefully the dump data can shine a light on the cause. Thanks ahead of time for any help.

A:Near Daily BSOD Since Hardware Upgrade


I'm not going to be the guy that provides the ultimate soultion for you; however, your plight has raised some curiosity on my part. Anyway, I looked up your specs and I see that Intel lists the i7 920 processor as being compatible with DDR3-800/1066 memory and the new Processor: i7 4770k is compatible with DDR3-1366/1600 memory. So, given that you have not mentioned anything about a memory upgrade that was coincident with your CPU upgrade, and given that your BSODs could point to a memory management problem, how did you handle the memory requirements for the new processor. Specifically, did you just overclock the old memory? Did you buy new memory and just forgot to mention it? Did you just leave the old memory running at 800/1066? I suspect that trying to use the old memory could be causing an issue for your new processor.
I see your mobo starts support at 1333Mhz memory so I assume all of my previous assumption do not apply

I recently reformatted my system and installed Windows 7 Ultimate x64. About a week after that, I installed a new video card. Shortly after installing the video card, my computer started to lock up and BSOD.

I removed the new video card(w/ drivers), and still had some issues. So I took the whole system apart, and reseated everything, double checking connections, just in case when installing the video card I had knocked something loose. I went ahead and left the new video card out of the system for troubleshooting.

It was going great for a day, but just decided to crash again and lock up. While looking for a way to open up the error files, I found you guys!

I would be extremely grateful if someone could look over my logs, and inform me the best route to take.

If I missed a single thing, please let me know.

Windows 7 Ultimate x64
Custom System, first OS was Windows XP Home Edition

CPU PhenomII 710- 1.5 Years old (Maybe a little less)
Motherboard Gigabyte MA78GM-S2H (rev 1.1) - 2 years old
Video Card- IGP, so the same age as the MB.
Power Supply Thermaltake 700w - 1.5 years old (purchased it same time as the CPU)
Memory DDR2 2Gb x2 - 1.5 Years old
Hard Disk - 1 year old
OS was just reinstalled about a week ago.

My rather new Sony Vaio started having BSOD crashes, usually (but not always) after being asleep.  After the BSOD, the restart would fail, with a message saying the operating system could not be found.  But, after a couple restarts or a cold reboot, it would find it and start without problem.  I reset the bios to defaults, did a system restore to before the crashes started- no luck.  To make matters more complicated, the BSOD flash so quickly I don't get error codes, and no matter what I do (check pagefile size/location, system settings), my computer doesn't make a dump file. The event viewer only lists a critical error that the system rebooted without cleanly shutting down first.  I called Sony, they had me run one of their hard drive check programs (not chkdsk and it passed), and then made me reformat/recover using the hidden partition and their recovery software.  Besides the annoyance of the clean reformat and all my software settings etc not restoring quite right, three days after the reformat and I have another BSOD, and again, no .dmp file or any other clues (and of course, all the previous error reports got wiped).

Well, Im new here, but I will inform you guys best I can.

It all started when I realized I downloaded the 32 bit operating system on my desktop. Now however, I got a BSOD when I inserted the CD into the desktop. People around the internet said that you must go ahead and format the drive, So, I went ahead and did that. Thus deleting the operating system in the process. Now, When I try downloading the operating system, I get this message:

Boot MGR is missing. Please restart the computer.

I have tried everything. Using my laptop to make a USB Drive to boot it up. I cannot do that because my laptop is a 32 bit operating system, and I want a 64 bit.

Please, I really do need help. The motherboard is a M5A 78L-M LX Plus with an AMD chipset. The monitors work fine and everything works until the boot MGR Pops up. I am puzzled because while working on computers in school, this only popped up when the operating system was on the harddrive. However, I cannot do anything at all.

Please, Help would be appreciated. Also, if you guys could give me a link to windows 7 Professional 64 bit download, that would be appreciated. I have both the 64 bit and 32 bit serial key.

Much appreciated.

Hi and welcome to SevenForums,

You can download the required Windows 7 installation ISO from this location:

Official Windows 7 SP1 ISO from Digital River ? My Digital Life

Use this tool to make a bootable USB (must be 4GB in size) with that ISO:

Universal USB Installer – Easy as 1 2 3 | USB Pen Drive Linux

Ensure that the PC can boot from a USB drive by checking that in the BIOS settings. Insert the USB, turn on the computer, and it will boot from the USB drive. Now install Windows 7 as normal.

Hey all! I am pretty new to this kind of Win7 issues, so I hope some of you will be able to help. Story goes...

After few hours of gaming the computer died. (It happened right after switching keyboards.) Now, on every setup BIOS(?) comes up with list of options (F2 enter BIOS, F11 boot options, F6 Flash etc.). After that a black screen with error message comes up: Missing Operating System.

I tried rebooting from USB (since I have no disk-drive) and I keep on getting the answer: Error Loading Operating System.

Any ideas?


A:Missing Operating System/Error Loading Operating System

All unlikely, but possible - (a) your HDD died. (b) your bios became corrupted (c) your HDD boot sector became corrupted (d) your HDD partition is corrupted.

Does the drive spin up when you switch on (feel it)?
Check the bios to see if the HDD is reported correctly and is at the top of the boot order.
Find a bootable CD - an OS installer, or create Easeus partition manager bootable CD http://www.partition-tool.com/personal.htm and boot from it. What does the HDD look like with Easueus?

These are the only 2 types of bsods that keep occurring. Also many times, when I try restarting the lap or maybe powering it up, I get a black screen saying "operating system not found". But when I power off and power on and follow this process a couple of time, I am able to boot up.

The blue screen errors has been occurring for atleast one and a half months now with a frequency of almost 2 to 3 times "EVERY DAY"...Its been very very agonising to say the least.

First of all let me tell you what are things I have done so far.
1) I have already activated "small dump file" in the advanced settings. Also the paging file is also I believe of the right size. My system RAM is 3740MB and the size of the paging file is 3834MB which I believe would be sufficient to be abe to write a small dump file. Also, I have disabled auto-restart upon system failure and hence the blue screen just stays whenever ... Read more

I formatted my laptop acer aspire 5735 and I installed windows 7 pro. ( i had vista before)
apparently my laptop does not accept neither windows 7 or 8. It suddenly crushes and displays "operating system not found" so I though that I have to update the bios. So I did (acer website provides them). After the bios update I get BSOD and then operating system not found!
How to solve it? I cannot bring my laptop to factory settings either. Please advise

Thank you,

Had the system for a few years just started getting BSOD. Went through updated everything I could think of. Ran 7+ cycles of memtest no faults found. Here are the two latest minidumps and my system specs. It happens at random time. In the middle of the night when no one is on up to high usage during game play. Started about 3 months after a full system format and restore.

Recently I had some issues with my Sony Vaio and found bad sectors within my HDD, and in doing so had a new HDD installed by technicians and my user profile transferred to my new HDD, but since receiving my laptop back I am now getting crashes after a couple of hours of extensive use where BSOD appears for a mere second before attempting to reboot but failing to find an operating system. From here I must power down my laptop forcefully then reboot again before it will find an OS. How do I stop these crashes from occurring?

Added an attachment of the dump Files.

I've had this new laptop (HP Pavilion dv6-1215sa) for about 3 days and it started playing up yesterday. I should mention that it came with Windows Vista but a friend upgraded it to Windows 7 the day it arrived.
The first issue flared up yesterday (after 2 days of perfectly fine running at home) and it wouldn't start up properly. Black screen, the lights on the keyboard came on and started flashing. After leaving it alone for a few hours it started working normally again, though it was a little sluggish at times. I didn't really think anything of it, and it may be unrelated.
When I got home and turned the laptop on, everything seemed normal enough. However, the laptop will now crash to a blue screen after about 20-30 seconds of being logged in. I think it also crashes if I remain on the log-in screen but it doesn't crash in safe mode.
The BSoD error reads as follows:
A problem has been detected and Windows has been shut down to prevent damage to your computer.

The system has encountered an uncorrectable hardware error.

If this is the first time you've seen this Stop error screen, restart your computer. If this screen appears again, follow these steps:

I have bought a new hardware recently ( Asus M4A78LT-M LE, AMD II X3 440 and Geil 2GB DDR3 1333 Value 9-9-9 ) I assembled everything togheter with hardware left from my old PC, which gave me this:

CPU: AMD II X3 440
Mainboard: Asus M4A78LT-M LE
Memory: Geil 2GB DDR3 1333 Value 9-9-9
Hard Drive: 160 GB Westgate
Video: Geforce 9600 GT
Power Supply: Chieftec smart 450W

I formatted whole HDD and installed fresh copy of Windows XP service pack 2. After few hours my windows started crashing ( BSOD, PAGE_ FAULT_IN_NONPAGED_AREA, STOP: 0x00000050, nv4.disp.dll, dumps of the BSOD in the attachment ) when I tried to play Crysis or Race Driver Grid. I checked other games and windows crash in all of them ( Modern Warfare 2, Need For Speed Shift, Left 4 Dead 2 ) with same BSOD. I tried reinstalling GPU drivers but that didn't helped, I also tried installing old ones, no success.
I have noticed that almost all of my applications suddenly crash ( Mozilla, Chrome, Office ) after few minutes of use. Furthermore, the files I download from the internet or copied from the usb sticks to HDD gets corrupted by CRC errors very often I reinstalled system two times but that didn't solved crashing and BSODS. After that I had all my hardware component tested and I also have found nothing:

CPU: Tested with orthos ( I ran two instances to test first two cores and the third one )
One hour test with no errors. ( 35 - 38 C when IDLE, 45 - 48 C when in stress )

A:BSOD and system unstabilitity after hardware change. Page Fault In Nonpaged Area

Requested data was not in memory. An invalid system memory address was referenced. Defective memory (including main memory, L2 RAM cache, video RAM) or incompatible software (including remote control and antivirus software) might cause this Stop message, as may other hardware problems (e.g., incorrect SCSI termination or a flawed PCI card).

nv4.disp.dll is a Nvidia display driver. Try the following:

1. Download Driver Cleaner Pro or Driver Sweeper (both have free versions; make sure the version will work with your OS) to your desktop screen and install.

2. Download the latest diver(s) for your video card but don't install them.

3. Uninstall your video card drivers and reboot your PC into Safe Mode. Run Driver Cleaner Pro or Driver Sweeper but ONLY for the video card drivers. I had someone use it on their chipset drivers! If it doesn't find any video card drivers that is quite okay.

4. Reboot and install new video card drivers.

Last night, my computer (specification in signature) was running the [email protected] client on both cores (nothing unusual about that) among other things and suffered a BSOD. After dumping something (memory or page file?), it restarted - it didn't stay on the screen, so I couldn't note down any information. After restarting, the computer got as far as:

Loading operating system_
Booting from CD_
(there's a random irrelevant CD in the drive and removing stops it from checking the CD but otherwise makes no difference).

At that point the screen dims (with the writing still faintly readable, and no progress is made.

I've run a Ubuntu live DVD and it sees the harddisks (both data and Windows drives) and the files are accessible.

When I attempt to repair the Windows installation via the Windows 7 DVD disc, no operating system is detected, even after loading the necessary drivers for my motherboard's RAID controller (the installation is not on a RAID-configured disk but I think the drivers may be necessary nonetheless based on my installation experience, about a year ago).

When I select "Use recovery tools that can help fix problems starting Windows..." and click "Next" and then select "Startup Repair", a repair is attempted and I am told to restart the computer to complete the repairs. According to the diagnosis and repair details:

Root cause found:
The partition table does not have a valid System Partition.

At the command prompt type:

Wait for completion. Type:

Determine which volume number and drive letter is your system drive/partition (where Windows 7 is installed) and make a note of it - you might need to use the label or the volume size as a clue.

Type the following, replacing c: with the drive letter of your system drive/partition and replacing # with the associated volume number - press enter after each:

bcdboot c:\windows /s c:

Now restart the computer, removing the CD from the drive as soon as the PC enters the boot process (allowing it to shutdown first).

I suggest you replace your registry hives from the backup.

You need windows boot media of some kind - the installation disc, or the win7 repair disc you ran off will do fine.

I'm new here. I already read a lot of posts to see if I could fix my BSOD problem but without luck untill now. However I saw that you guys were able to help a lot of guys and therefor I hope you'll also be able to help me with my problem.

Last week I did an upgrade of my PC. Basically I kept my 2 HD's, my PSU (recently renewed it because my old one got defective) and my case.

I bought these Items to upgrade my PC:
2X Corsair XMS CMX4GX3M2A1600C9 (so 8GB in total)
AMD Phenom II X6 1055T 2.8Ghz Boxed | HDT55TFBGRBOX
Asrock 870 Extreme3 | 870 EXTREME3
Samsung EcoGreen F4EG. 2TB | HD204UI (add on to my other 2HD's I already have)
Sapphire HD 6850 1GB GDDR5 PCIE | 11180-00-20R

I did a clean install (windows vista 64bit home basic) and installed everything on the new Samsung drive.
However from day one I'm getting sporadic BSOD's. Strange thing is that I have the impression it's more when I'm just downloading or streaming a video. Never happened during gaming (yet), I did happen during a 10-tabling poker session :/
I did se a few other times that my poker-tables were getting messed up (picture included) but I didn't get a BSOD in these cases.

I tried a lot of things but don't have the feeling that I'm close to solving it:

*I turned off (or disabled) all the items in the BIOS that state that it can cause instability?
*Checked the BIOS version of the mainboard but V1.60 is the latest.
*Performed driver sweeper (even after clean install) did find some NVIDIA drivers an... Read more

Hi, Hope i am posting in the correct forum.. Would like to apologise in advance if this is a little long winded but i need your help WhiZZ KiDS,n need to put you in the picture right away, Right here goes:

Recently decided to upgrade my system from:

AMD Athlon 64 4000+ 2.4GHz
Abit AN8 32X SLI MoBo
EVGA 7950GX2 Superclocked
1024 DDR2 kingston Value RAM (1 x 1024)
Hyper Type-R 550W PSU
Western Digital 250GB SATA HDD 7200RPM [on its way out]


AMD Athlon 5200+ X2 2.6GHz
Asus CrossHair SLI MoBo
Keeping same GFX Card cos im skint!
2048 Corsair TwinX XMS2 PC 6400, 800MHz RAM
Thermaltake Toughpower 700W PSU
Western Digital 320GB SATA HDD 7200RPM

At first when building the system i had problems on Powering up,
Wouldnt even get as far as the POST before powering off abruptly..
Eventually narrowed this down to the new CPU which was Dead on Arrival
through the component elimination proccess..

Anyway i RMA'd the CPU, which was found to be faulty and recieved
the new replacement a few days back.

Events since receiving the new replacement CPU are as follows

1. Installing CPU, All went to plan no problems this time, PC was able to power up successfully, complete POST & access BIOS.

2. Installing windows x64..Created default partition.
Obviously because its a new HDD [WD 320GB] i would have to format the drive, There were 2 options available for Formatting:

Right so a couple of weeks ago I get the parts needed to upgrade my AMD Phenom II X6 1045T system. I got a new motherboard, an MSI 990FXA-GD80 Rev 2, and 16gb of DDR 2 1600 GSkill memory. Also got a new Fractal Design Define R5 case. I also got a Western Digital WD2003FYPS-27W980 2tb Enterprise Grade hdd as a new primary HDD. Now, this gets a bit convoluted so please bear with. Originally I had a 1.5tb primary, a 2tb and a 640gb data drives. The idea was to make the new 2 tb drive the primary, and replace the 640gb with the old 1.5tb primary. So I get it all together, swapped over the CPU, etc and get it working. I reinstall Windows 7, get it updated, all running relatively well, partition the new primary as a 500gb C: and 1.5tb D:. 2 days later Win 7 *loses* the new primary, literally, Windows Explorer, which I had up copying files off the 1.5tb doesn't show C: and D: not there. Programs crash left and right, complete chaos. I reboot into the bios and bios shows the HDD is there. I reboot and it boots fine if you don't mind the data corruption out of the wazoo due to the drive going missing. So I limp along for 2 days until I have a day off of work and then reinstall Win 7 again. With in the first day it BSOD twice, both Kernel Inpage Data Error. A week later it does it again while attempting to play a video game. And now and again it'll freeze, I do mean whole system freeze, not even the clock ticks off, for several minutes. So I run Passmark on the HDD to see if it's fail... Read more

A:Computer Freezes and BSOD after a system upgrade

There is no reason to believe the old hard drive can't be dying. There are 2 times when it is most common for hard drives to fail: when they are new and when they are old.

The "It *seems* to be failing as it's going chick chick chick chick chick " is the dead giveaway however. Classic symptom of the heads not parking. That drive is on it's way out. Start retrieving and backing up data now.

How does the PC run if you remove the failing hard drive?

So, let me see. I upgraded my system to an MSI 990FXA-GD80 with GSkill Ripjaws X 16gb 1600 (in 2x8gb sticks that came packaged together so presuming they matched them.) F3-1600CD9-16GXM that GSkill says is compatible with the MSI board. Though the bios only sees it as 1333 when set to auto. No luck unsetting auto and setting the values to what is listed from GSkill, still BSOD errors almost daily and total system freezes that last several minutes that happen every few hours. So I can safely assume that isn't the issue or it's one symptom of a bigger issue. Already did a chkdsk boot up scan of the primary hdd and no errors where found. Did a boot up MemTest86+ test, in one pass no errors. Since I am getting one of two BSOD errors, Kernel InPage Data Error and a Stop 0x000000F4 error, I am pasting the requisite zip file and hope someone can point to what might be the problem. I already reinstalled Windows 7 twice, once after the upgrades and one a week later, already that was about a clean install, in both cases, as one can do, I formatted the partition Windows 7 is installed on before reinstalling Windows 7, didn't fix the problem. Oh! The dmp files in the archive are old, one is from the 17th the other from the 20th, even though according to Control Panel -> System -> Advanced Settings -> Startup & Recovery shows it is set to create a dump file and to not restart automatically.

Hello BelGarion mate the one thing you mentioned re the RAM only showing up as 1333MHz now if the new board is anything like my Asus Ivy Bridge one the EUFI BIOS has 1333MHz as a default speed for the RAM and it has to be clocked up if you want any speed out of the RAM - mine is fully clocked to 2400MHz.

Now have you got any new dump files at all??

I have an old HP Pavilion 8260 that I got for free which is having some odd issues. Any time I try to boot, I get one of these 2 errors (first it was always Operating System Not Found, now it's Missing Operating System).

Here are the steps I've tried so far: I tried to boot from a floppy with a disk I know works; tried to boot off of the CD Rom; Tried disconencting everything except Floppy, CPU, and RAM; Tried resetting the BIOS by selecting "Set to Default" and by pulling out the CMOS battery (it was after doing this that it switched to the Missing OS error message).

The hard drive is dectected in the BIOS, as is the CD Rom and floppy drive. It properly recognizes the amount of RAM.

I am fresh out of ideas, even though I'm generally pretty good at this. If anyone else has any advice, it's greatly appreciated.
