I was troubleshooting my BSOD for about a week and I need help.
Here's where I am. I cleaned the chassis and reinstall all components. Then I ran memtest for 8 passes without error. Then I got Majorgeeks through my dieting rigorous anti-malware. And there is no malware on the computer. I could not find any obvious driver conflict. So I ran SFC/scannow and it found some errors, he couldn't fix. So I finally did a repair installation to see if file system cleaning would eliminate blue screens.
I always get a BSOD.
Which leaves me with what? A bad GPU? Unknown driver conflict? Bad motherboard?
Here comes bluescreenview log for you to look over. If someone could help me please clarify, I'd appreciate it really any help I can get.
Thank you.

IRQL_NOT_LESS_OR_EQUAL (a)
This indicates that Microsoft Windows or a driver in mode accessed kernel memory paged at DISPATCH_LEVEL level or above.
This bug check is issued if the memory paged (or invalid) is accessible when the IRQL is too high. The error that usually generates this bug check occurs after the installation of the faulty device driver or service system, BIOS.

Hello
I have some unusual difficulty get my images to float left/right in order to have text next to the image. In the image I provided, the red arrow is where I'd like to be but little text whatever I put in the CSS file, the text starts at the lower right part of the left side of the image floated. Can someone help me understand what is happening? The code for the HTML code is located here http://codeviewer.org/view/code:1f51 the code for the CSS is here: http://codeviewer.org/view/code:1f52
I use the CSS code for a Web site I designed and that works very well in this Web site. Why isn't it working here? The name of the image is "fundraiser.jpg".
Thanks for your help!
Problem is caused by you not declaring the correct instructions for .float-left css class selector:
Change this:
{.float-left
margin: 10px 5px 0 0;
}
To do this:
{.float-left
float: left;
margin: 10px 5px 0 0;
}

Hello
We have a database of GR 11, 2.
I manually deleted a few lines of sys.aud$.
remove the sys.aud$ where trunc(ntimestamp#) < 16 August 13 ';
commit;
But I have still a few lines in dba_audit_trail.
SQL > SELECT COUNT (*) FROM DBA_AUDIT_TRAIL WHERE TRUNC (timestamp)
SQL > = 15 August 13 ';
COUNT (*)
----------
26110
SQL > SELECT COUNT (*) FROM SYS. AUD$ WHERE TRUNC(NTIMESTAMP#)
SQL > = 15 August 13 ';
COUNT (*)

0
Please let me know after you remove manually, it is something else I need to do.
Try this one:
SELECT COUNT (*)
OF SYS. AUD$
WHERE TRUNC (((FROM_TZ (ntimestamp #, ' 00:00 ') in the LOCAL CAST) AS DATE)) = 15 August 13 ';

My Macbook Air is only 8 months old. I only use it for word processing and surfing the internet. Yesterday, it started to make a noise maybe the fan. I've done all the troubleshooting steps described in Apple and to other useful sites, but nothing helped. Is it still fixable? What could be wrong? Is this laptop still under vices? Please help as soon as possible. Thank you.
This laptop is still under warranty.
It may be a problem with the fan, but it can also be a problem of some adware or other infections.
It would be useful to find when you download the application Etrecheck of etrecheck.com well known information
It produces a list, you can share it to the clipoard and paste here.

HP officejet pro 8500 wireless, windows 7 sp1, 'y' cartridge must be replaced on-screen, no change in software.
running out of ink during printing... draws 1/4 page and then fades down to nothing at the bottom of the page. History: necessary at the end of the work (a little), but completely run out of black ink. a friend gave me her used 1/2 940 gen ch black until I got a new. I have a new hp 940xl but it's always the same, I ran everything in the Toolbox align, feed, etc., but it will always print a full page? It's like the print heads are empty and do not fill the cartridge? Please help me. She was purchased on 29/11/11 but received 12/15/11 for my birthday children so its just out of warranty thank you, Darren
It seems that the print head was filled with air. Once there, the air is very difficult to remove.
try to clean the print head using the printer services.

want a row but get several lines
Hello
There is a report of payment details. He was asked to change such that there is only one line by the name of checkrun.
I made a kind of Group on all amount fields no and switched the field amount to the sum instead of retail.
Is what I get for each checkrun name, a line with all the information I want, but in addition and the additional row with the same amount of repetition. Verify the removal of duplicated lines does not help. Didn't help not make some kind of Group on the quantity; It gives just blank lines after the line required.
This is urgent. Can anyone help?
Thank you.
LeahHi Lea,.
Maybe the field you see and which has not been deleted causing the problem,
How complicated it will be to re-create the report with the kind of group you want?
I have a feeling that if you recreate it, it will work correctly.Tamir
