Windows 7 Desktop Display - Columns Of Horizontal Lines

[Del56]

Columns of Horizontal Lines appear randomly and frequently on my desktop. Not always but sometimes 2 or 3 times a day. Images of the display on my desktop are attached along with my pc specs and a detailed version OURPC.txt. Some days they never appear. My computer freezes as a result and only a reboot (Front panel button on hd) solves the fault - but not always. Occasionally, the lines appear at boot up immediately after the 'Welcome' screen. A reboot into Safe-Mode usually is fine. I got them today once, and a normal reboot was fine and no problems as i type. Adding to this i get the BSOD instead (hardware? i know) but have no way of telling if this is related to the above problem or not. This is increasingly annoying when working online, emailing or viewing. The lines appear over the desktop display or browser. I know when it's going to happen from a buzzing sound through spkrs/headset and The red flashing hd light just switches off. The whole thing freezes and as i've said i have to restart via the start button on the hard drive itself. (the small button on right in image 1054). If i get the lines 2 or 3 times i just boot into safe-mode networking and work from there. Of course i only have the basic windows display available to me so am limited.
The most uptodate driver for the Intel HD adapter is Jan2012 and i have that. Incidently i had the same problem with the previous driver so have ruled that out. Is it something simple like adjusting settings or some kind of tweak maybe? Or a physical problem with the onboard graphics? Whatever it is, is damned annoying when in the middle of working on something online , the lines appear and have to reboot. I have trawled google for an answer to no avail but the nearest similar visual corruption image to mine is Type A on this page. Link Removed - Invalid URL -but i dont have a Lenovo anything. Mine is a desktop pc. I have run various programs to check the system incl Intel SIU, Speccy etc. but NONE report any problems with the system. I hope i've provided enough detail and pics (each taken at occurrance) for my problem and would welcome a solution. Thank you for reading. I appreciate it.

Sounds like some type of noise is getting in the system. Perhaps try changing the Electrical outlet you are using. If you have any machine running on that same circuit, it might be related.

Maybe try getting a Universal Power Supply that could smooth out the power. If this doesn't help, perhaps look into a new power supply.

There is always, of course, a possiblility you have a problem with the Graphics device, but I do not think it is a driver.
