Windows 7: Blue Screen only during start up or reboot

21 Apr 2013   #1

Windows 7 Ultimate SP 1
Blue Screen only during start up or reboot

Alright, so i've had this issue for a while, and it's only been getting worse.

Whenever I have to reboot my computer, or when i'm turning it on after it's been powered down, it is rebooting just as it gets to the Windows loading screen, and usually fails to start up on second boot sending me to the start up repair tool.

Typically to resolve the issue temporarily, I have had to use the last known good configuration, but recently that isn't even working. I am now having to use system restore to go back a couple of days, no matter what i've done, or have been doing.

It has also been having issues waking from sleep (which is the primary method of "shutting it down" as of the last 6 months) Often times my computer will simply say "No signal" until I restart or shut down the computer.

Most often during these auto-reboot loops a BSOD will flash up briefly before it restarts. It has also been mentioning something of possible graphics card issues, and most recently has mentioned hardware being recently connected that could be causing the issue. Though if I remember correctly, that is a generic message.

When going through the start up repair last night I gathered this information.

Root Cause Found:
Unknown Bugcheck: Bugcheck 124. Parameters = 0x0, 0xFFFFFa8008231038, 0xb2000040, 0x800.

Repair Action: System files integrity check and repair.

Result: Failed. Error Code = 0x490
Time Taken = 753594ms

I then later got a BSOD:

Stop 0x0000009C

And finally I had a list of 15 unreported problems that popped up on me after I finally got into Windows last night. All 15 were exactly the same, which are as follows:

Problem: Video hardware error
Files that help describe the problem:
View a temporary copy of these files
Warning: If a virus or other security threat caused the problem, opening a copy of the files could harm your computer.

This is all the information I have, and i'm more than willing to provide what ever else is needed to help resolve this issue, thanks ahead of time.

The only dump included indicates a BugCheck 124 and is an unrecoverable hardware failure. These are hard to track down even when the WHEA record is present. In your case, it's indicating a CPU L0 cache error. This is the primary processor cache from which all data and code flows. Processor cache errors can be caused by low voltage, high temperatures and/or system memory errors.

If you are OCing the CPU, return it to default timings and voltages.
If you are not OCing, use a hardware monitor that will display voltages and temperatures and monitor for excessive heat and low voltages. Intel specifies a maximum of +/- 5%

Why doesn't it crash, freeze, or give me a BSOD while i'm actively using it?

Personally I feel it's virus related. When I was using Ad-Aware, I was continuously receiving alerts that it shut down unexpectedly.

I haven't tampered with the CPU timing or voltages, i'm not that advanced of a user. This computer was built by a co-worker of mine, wasn't a fresh install of Windows either.

So, where would I start by tracking down these potential hardware issues?

*On another note* It's nearly impossible to boot up with my DVD ROM connected. The initial boot screen that shows the IDE slave and master connections. (Which is also strange because it's not IDE connection, it's SATA) Figured that might be useful.

Open up a new thread inside SYSTEM SECURITY and we will have the malware removal experts run a few programs and see if you have any adware or viruses roaming around that is causing your BSODs . Just as a precaution .

This computer was built by a co-worker of mine, wasn't a fresh install of Windows either.
Unless it's a Dell computer, the version of Windows the builder installed is fraudulent.

BIOS Version/Date Phoenix Technologies, LTD 6.00 PG, 9/1/2008

Return the PC to the builder and have him install a legal version of Windows 7 then update it along with the BIOS and drivers for the motherboard. We can't assist with repairing fraudulent software.

On a side note:
I don't particularly trust Ad-Aware. It's considered malware in its own right. Also, AVG is often troublesome in Windows 7. I would recommend uninstalling both and use Microsoft Security Essentials (MSE) as a real-time AV scanner and the FREE version of MalwareBytes Anti-malware (MBAM) as a stand alone scanner.

Issue Resolved

Yeah, that's all well and nice and everything, good to know my co-worker lied to me, but whatever.

I just wanted to point out that it was my graphics card that failed.

Boots like a charm now.

Yep, I see that now. I misread BUSL0... to be the cache. Sorry.

Good to hear you got it going. Do check on your OS though. The product code comes back on a Dell OEM machine and you may find it not working after a period of time. Or the builder installed an old Dell motherboard in your new build. The BIOS is old. Good luck.

Eh, it happens. Yeah, my neighbor actually had the exact same card, but wasn't using it. Actually had two, which he said I could hook together and have some fancy doodad that i'm gonna look into later.

Regardless, yes, i will look into my OS, my buddy is gonna see if he can find a cheap copy of 7 Ultimate for me.

I hear that you can install the OS over the current one without affecting user installed items now (like the Mac OS) Is that true?

You can do a Repair Install but only for the same product code. A new product code will require a new install with a valid key for that product code. There are many product codes for Windows 7 Ultimate. (That how we can tell the origin of the product code.)

Good to know, but that kinda sucks.

Is it possible that he just installed in on another computer first, and then on this one?
