new asus ul80vt constant BSOD

[vlad4]

Recently i bought a new Asus ul80vt.

I installed a fresh W7 system.. (even there i was having problems including install hang on "expanding files xx%" )

When i finally installed all drivers i started to get bunch of BSOD's which however managed to fix.

- drivers updated
- bios updated
- drive tested
- ram tested with memtest


Now i'm getting Cx000021a BSOD 0x000000 (0xc0000428 0x00100448) which gives no dump files.

Sometimes windows only hang on "starting windows" with HDD led on.
Windows starts ones / 10 times and even if it starts it it hangs or getting errors in device manager.

I'm seriously thinking about sending laptop for repair but i'm pretty sure that they will send it back with annotation that there is nothing wrong with hardware.

please help because i'm getting crazy.

Download a copy of Memtest86 and burn the ISO to a CD using Iso Recorder. Boot from the CD, and leave it running for at least 5 passes.

Try this free video stress test: FurMark: Graphics Card Stability and Stress Test, OpenGL Benchmark and GPU Temperature | oZone3D.Net

FurMark Setup:
- If you have more than one GPU, select Multi-GPU during setup
- In the Run mode box, select "Stability Test" and "Log GPU Temperature"
Click "Go" to start the test
- Run the test until the GPU temperature maxes out - or until you start having problems (whichever comes first).
- Click "Quit" to exit

Try this free stress test: Free Software - GIMPS

Prime95 Setup:
- extract the contents of the zip file to a location of your choice
- double click on the executable file
- select "Just stress testing"
- select the "Blend" test. If you've already run MemTest overnight you may want to run the "Small FFTs" test instead.
- "Number of torture test threads to run" should equal the number of CPU's times 2 (if you're using hyperthreading).
The easiest way to figure this out is to go to Task Manager...Performance tab - and see the number of boxes under CPU Usage History
Then run the test for 6 to 24 hours - or until you get errors (whichever comes first).
The Test selection box and the stress.txt file describes what components that the program stresses.
