Windows 7: ntoskrnl.exe causing multiple BSODs, please help!

ntoskrnl.exe causing multiple BSODs, please help!

So, out of nowhere last night, my PC suddenly BSOD'd suddenly while just browsing things. It's never had any issues, it's about a year old now. It happened again at some point overnight as I woke up to the login screen and it telling me it recovered from a blue screen. Then, it happened once more today about 2 hours ago during a League of Legends Dominion match.

My girlfriend suggested from what little I knew that I update my graphics drivers, which I did and rebooted. Still, if I could get anything more concrete it'd really help.

The last error that popped up was

I'm using an HP Pavilion Elite HPE, with an i7-480 processor, 8GB of RAM, and a Radeon 5770 graphics card. I ran a monitoring program and the core temperatures were around 55-68 C while idling, and the graphics card never got above 57 C, so it doesn't look like it's overheating. I'm including the minidumps, hopefully someone can help point me in the right direction here.

Two issues


1-Please remove any CD visualization programs such as Daemon Tools and Alcohol 120%.


They use a driver, found in your dmp, called sptd.sys, that is notorious for causing BSODs.

Use this SPTD uninstaller DuplexSecure - Downloads DuplexSecure - FAQ

when you're done you can use this Freeware MagicISO Virtual CD/DVD-ROM(MagicDisc) in its place.


2-Memory exception

These crashes were caused by a memory exception. Please run these two tests to verify your memory and find which driver is causing the problem.


*-Memtest.


*Download a copy of Memtest86 and burn the ISO to a CD using Iso Recorder or another ISO burning program. Memtest86+ - Advanced Memory Diagnostic Tool

*Boot from the CD, and leave it running for at least 5 or 6 passes.

Just remember, any time Memtest reports errors, it can be either bad RAM or a bad motherboard slot.

Test the sticks individually, and if you find a good one, test it in all slots.

RAM - Test with Memtest86+



*-Driver verifier

Quote:
I'd suggest that you first backup your data and then make sure you've got access to another computer so you can contact us if problems arise. Then make a System Restore point (so you can restore the system using the Vista/Windows 7 Startup Repair feature).

In Windows 7 you can make a Startup Repair disk by going to Start....All Programs...Maintenance...Create a System Repair Disc - with Windows Vista you'll have to use your installation disk or the "Repair your computer" option at the top of the Safe Mode menu .

Then, here's the procedure:
- Go to Start and type in "verifier" (without the quotes) and press Enter
- Select "Create custom settings (for code developers)" and click "Next"
- Select "Select individual settings from a full list" and click "Next"
- Select everything EXCEPT FOR "Low Resource Simulation" and click "Next"
- Select "Select driver names from a list" and click "Next"
Then select all drivers NOT provided by Microsoft and click "Next"
- Select "Finish" on the next page.

Reboot the system and wait for it to crash to the Blue Screen. Continue to use your system normally, and if you know what causes the crash, do that repeatedly. The objective here is to get the system to crash because Driver Verifier is stressing the drivers out. If it doesn't crash for you, then let it run for at least 36 hours of continuous operation (an estimate on my part).

If you can't get into Windows because it crashes too soon, try it in Safe Mode.
If you can't get into Safe Mode, try using System Restore from your installation DVD to set the system back to the previous restore point that you created.

Well, damn. Are you sure it's a memory issue? Someone said the issues were also caused by poor drivers like the graphics card, which would be a lot easier (and free..) to fix, if so.

Mine were a few months out of date and I went and updated them yesterday afternoon, it's been running for about 18 hours now, whereas the 3 BSODs were about 5-6 hours apart...

Fantastic. I thought everything was fine, then suddenly, it bsod's again. I don't know what the hell is going on. I need the computer for work atm, I can't just shut it down for hours to let this memory scan run until overnight. I'm stuck until I go to bed.

I wasn't even doing anything intensive, just sitting here talking to someone on IRC when it just flickered to black out of nowhere, then popped up with this.

Attaching the most recent minidump as well. Someone please help more, with a better explanation of things.. (i.e. why it's memory, or whatever else one finds in the dump... )

I'm at wits' end with the inability to figure out wtf is causing this. It's not overheating, it's not the graphics drivers, running malwarebytes now to see if it's a virus, the computer itself says everything is behaving properly... idk what to do... ~.~ This computer isn't even a year old, and I don't have money for a new one. Could really use some more concrete help...

Still haven't gotten a chance to run the ram check... Just happened again. -_- Nothing running but Firefox, mIRC, and Steam... ~.~ I'm at wits' effing end with this stupid thing I have no idea what the hell the problem is or why it's just screwing up out of nowhere...

'Nother minidump. Can someone please explain what about the dumps I'm uploading suggests it's a memory issue, instead of just saying "It's your RAM do X"? I'd really like some concrete reasoning like "It says x, so do y". ~.~

I've gotten Memtest to work now, booted from a CD. It's made 5 passes and had 0 errors, so now I'm even more at a loss than I already was. I also removed the driver used by daemontools, even though I got another BSOD after doing so.

Given that it keeps saying caused by ntoskrnl.exe, could the installation be corrupt somehow? I'd hate to reformat but I don't know what else to do =.=

Ergh... Why is this forum so dead? XD;

I'm thinking IE might have something to do with this but I can't figure out how to uninstall it. Ever since the BSODs started happening, IE has also been crashing with the event name "BEX." I don't know if a Buffer Overflow can cause a BSOD but it might, and the timing fits.

Problem is I'm not using IE, ever. I've used both malwarebytes and Ad-Aware and neither of them turn up any Malware results, yet I keep getting "Internet Explorer has stopped working" out of nowhere. I can't seem to uninstall it either, as it isn't showing up in the Programs list or list of Installed Updates. >.<
