[curiousgeorge]

Hi guys

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 ?

Hi Ken

i have a DPU250 just checked what you said cd/dvd is not even listed

[KenB]

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.

Hi ken just took back off pc no cd drive installed see pic

just had the back of the pc there is no cd drive installed[ATTACH=CONFIG]1484.vB5-legacyid=2572[/ATTACH]

[KenB]

no cd drive installed

I think that explains it :) :)

[curiousgeorge]

I guess it does my friend thanks again for your help

[curiousgeorge]

Sorry the reason i was given this is because sometimes the screen does this on start up sometimes it sorts its self sometimes not any ideas please[ATTACH=CONFIG]1485.vB5-legacyid=2573[/ATTACH]

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.

[curiousgeorge]

Sorry Ken what do mean central white area?

[Dalo Harkin]

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

[curiousgeorge]

i will strip it down later give it a clean....i only have the one port

[curiousgeorge]

Hi guys

stripped it down heres what i have although it does look quite clean in here[ATTACH=CONFIG]1486.vB5-legacyid=2574[/ATTACH][ATTACH=CONFIG]1487.vB5-legacyid=2575[/ATTACH]

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.

[curiousgeorge]

just tried it 3/4 times with no back on starts up fine so i will keep restarting it

[curiousgeorge]

Scrap that ..its cocking up again lol

[KenB]

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.

[curiousgeorge]

Hi Ken

is this any help?[ATTACH=CONFIG]1488.vB5-legacyid=2576[/ATTACH]

[KenB]

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?

[KenB]

the stress test is taking forever over an hour is this normal?

No - I would have thought that it should complete in far less lime :(

 

This video only runs Furmark for 60 seconds -

 

Did you get any results ?

[curiousgeorge]

No Ken it went on for 3 hours lol ill try again later

[KenB]

Hi George,

 

This may help - click here

[curiousgeorge]

Thanks Ken only got a bloody blank screen now lol

[KenB]

This doesn't look good George

I suspect that the "Graphics Card" was on its way out and the stress test has finished it off. :(
