Hardware: HP Compaq Presario 2170US
Platform: Windows XP Pro (clean install)
Video Adapter: Radeon IGP 340M
Driver 6.14.10.6436 (5/15/2004)
Chip RS200M AGP (0x4337) Integrated
64 MB, Internal DAC(400MHz)
Monitor: Digital Flat Panel
60 Hz Refresh Rate (only setting possible)
1024 x 768 resolution, 32 bit color depth, 96 dpi
Video Driver & Control Panel: ATI
Display Driver 8.003.3-040515a-016016C
Control Panel 6.14.10.5102
Issue: Flickering horizontal lines across the monitor.
The flickering is intermittent, it can be gone for weeks or longer without a flicker. Then it will develop and worsen over time until I canÂ’t even see the screen to shut down the computer. It doesnÂ’t seem to matter to the flickering if the computer has been on for a minute or a day.
When I plug in an external monitor, it has perfect display, even when the laptop monitor is unreadable.
Anomalies:
While playing a DVD on ‘Intervideo WinDVD 4’, it displayed perfectly if I didn’t open the player window to full-screen. Once I enlarged the player window past a certain point it would go from clear to (not just lines) huge blocks of rapidly scrolling graphical chunks. Totally scrambled. Before this last use of the player, I could maximize the player window without problems.
Right now I have lines (more prominently off the left edge of the screen) across the screen, but I can still see to work on it. If I place my mouse cursor in the lower-left corner, the whole screen rotates rapidly (bottom to top –or- top to bottom).
History: I acquired this laptop because of the flickering horizontal noise – So far…
I wiped the Hard Drive and reinstalled the OS from a new disc version, twice.
I flashed the BIOS to the newest version I could find from the laptop manufacturer.
I updated the AGP BUS driver and reinstalled the driver, several times.
I performed MemTest86 on the RAM for many passes including fade-testing.
I searched Google far and wide for similar problems to mine.
I contacted HP to no avail ;-)
I opened the box (partially) and re-seated the video monitor cable onto the motherboard.
(At which point it got really bad for a minute then became perfectly clear, for several weeks before it acted up again.)
Summary: Because of the anomalies of using my DVD player and re-seating the monitor cable, I canÂ’t decide if itÂ’s a hardware or software issue. Was the cable thing a coincidence? Was the DVD player just an artifact issue? Is this a refresh issue or ???
If anyone can help me diagnose this, I would be deeply appreciative.
