Hi George,

does this mean there is no cd/dvd installed on my machine?
No not at all George - sometimes the upper and lower filters are not there.
If they were - in your case - you were going to delete them anyway :)

If you go to Device Manager [ Start > type in...devmgmt.msc ...hit Enter ]

1. what is listed against CD / DVD ?
2. Any red Xs or yellow exclamation marks ?

3. Which model number Samsung do you have ?

Just checked the Samsung site - click here - only VGA and WiFi drivers available which is ODD !!

just checked what you said cd/dvd is not even listed
When you reboot the system if there are no drivers present Windows should detect "new hardware" and install default drivers.
If it isn't doing this there may be a fault with the hardware itself.
It could be as simple as a bad / loose connection to the DVD drive.

Try this FixIt - click here
[ for XP - Vista - Win-7 ...]

Hi George

Is the screen just the central "white" area ?

This could be linked to a faulty Video Card or driver.
You could look at updating the drivers using the link to the Samsung site that I gave you.
I doubt that this is the cause - but it is worth a try.

If the motherboard is easily accessible you could try using a can of compressed air to shift the dust.
You can do this through the vents [ less effective ]
Compressed air available at most computer stores / car spares places etc.

You normally get distortions like that when there is excess heat within the system (normally the graphics card, which will be onboard in yours by the looks of it)
you can try the compressed air as has already been suggested.
If you have more than one GPU port on the back of the PC try another because its not uncommon for one to stop working with all the plugging in/out

Hi George,
I thought that your pics were after you had cleaned it. [ from your comment - obviously not :) ]

Can you run it with the panel off?
If so - give this a try.
You could also direct a fan onto the motherboard.

If it runs better with the panel off it would seem to be an over-heating issue.

Hi George,

If you can ......

Download Speccy from here onto the problem computer - click here - the FREE version.
Install and run it.

Click on "File" > Publish Snapshot
Copy the link and paste it here please.

It will give us details of your system [ no personal details ]
I am interested in temperatures.
You can post these separately if you wish.

Those temperatures are OK - but this is taken when things are working.

Click Start > Run
Type in .....dxdiag .....Enter
Click on "Display" tab
Are any problems indicated in the Notes box ?

Furmark do a stress test software. You can download it here - click here

I found test results for a similar card to yours

Hi Ken
no problems detected in dxdiag but the stress test is taking forever over an hour is this normal?
