It is quite likely a problem with a overheating video card. The CQ60 laptops had a overheating issue that was to do with the video card. This CQ70 may be experiencing something similar. The solution for the CQ60 was to download the latest Nvidia drivers and install them. Give that a go. If no luck then you may have to chalk it up to hardware failure and replace the laptop. The video card is integrated so you can't just replace it.

Just started up my Compaq Evo N600c about an hour ago as usual, the word COMPAQ came up(as it does) and then the screen went black, and around 40 short, thick, vertical, white lines appeared. Slowly they...


no photos presented of screen messing up, (sadly)
compaq = old, too old, why mess with so old a box/?
the screen is bad, and $100 is 5 times what it is worth as a whole.
find a PC 10 years or newer so its VIABLE and supported
and do not buy XP or VISTA anything,both are DEAD now.
Black with lines. (LCD problems, ('damaged")
most times means bad screen.
does the external screen work, ? at the 15pin jack there, called VGA.?
using and external screen (plugged in)
when did this PC last run good. 5 years ago?

using an external screen, re-install the unstated OS.

it came with WIN98 or XP (what it has now, click system in control panel and read what it is)
both those 2 are Dead OS/s now... dead and Virus magnets .

oddly HP has not deleted the over 10 year old support page
as most are..... that old. (you are very lucky, its like 1% chance this.)

Blue screen of death


It is the HD thats is the cause of you blue screen of death. To fix this problem you must run a scan disk in windows and let it repair the problem. If you cant repair it through windows you will have to use your windows disk. Boot Pc up with windows disk in CD Rom and fit F-12 select boot to dvd or cd rom option. Select repair windows, then you should get a black screen with comand line like a DOS screen. Type in C:/Fixdisk.

Blue out of focus; casting blue "glow"


Try changing the coolant in the blue tube. Contaminated coolant will give a halo look to the affected tube and you will experience difficulty focusing that color.Phillips/magnavox's blue is the tube most often affected with the contaminated coolant issues.
