Windows 7 Windows 7 graphics problems

[AberdeenBill]

Hi all,

I will try to keep this brief...

We have an Acer Aspire M3802 (Windows 7 home premium, 64-bit), with a generic 1280 x 1024 monitor, which has worked beautifully for three years, until last week. We started to get random BSODs, which increased in frequency to about one every five minutes. Running Memtest revealed the presumed culprit -- one of the Transcend 2 GByte memory modules gave about 1 million(!) errors after a few cycles of Memtest, so it was removed, leaving the other 2-GByte module.

The computer was, shall was say, overloaded with junk, so after saving documents and photos etc. I reloaded the operating system, and the graphics problems began (Intel G45/G43 chipset on integrated graphics). Everything was very buggy, with black checkerboard patterns in right-click windows and the Windows gadgets such as the clock. Random black and white bars appeared on the desktop and a couple more BSODs occurred. I uninstalled the graphic drivers, ran Driver Sweeper, reloaded drivers, but all to no avail.

I then switched from 32-bit color depth to 16-bit in the Intel graphics media accelerator driver and everything is now (I hope) working perfectly. 16-Bit color is probably OK for most purposes, although 32-bit would be better for photo editing.

So...

Any thoughts as to why 16-bit color is working and 32-bit is not? I presume(?) that the pre-crash system was working with 32-bit. Would buying a replacement 2-Gig memory module change anything? Would it be a good idea in any event?

Thanks for reading,
Bill

Bill, It sounds like you've been through quite a troubleshooting journey with your Acer Aspire M3802. Let's address your concerns step by step: 1. Graphics Issues and 16-bit Color: The switch from 32-bit to 16-bit color depth that resolved your graphical issues could indicate problems with either the graphics card or its drivers. When you're running at a higher color depth like 32-bit, more graphical data needs to be processed. If there are underlying hardware issues or driver conflicts, this can lead to visual artifacts like the black checkerboard patterns and random bars you experienced. By lowering the color depth to 16-bit, you reduce the amount of data being processed, potentially bypassing the problematic areas that were causing the issues. 2. Memory Module Replacement: Since you identified one of your memory modules as faulty, replacing it with a new 2GB module could potentially improve the overall system stability, especially if the remaining module is also showing signs of wear. Faulty RAM can cause a variety of issues, including random crashes, freezes, and BSODs. Replacing the faulty module might help in preventing further crashes and improving the overall system performance. 3. System Cleanup: You mentioned that your system was overloaded with junk before the crashes started. After reloading the operating system and removing the faulty memory module, it's a good idea to ensure that your system remains clean and well-maintained. Regularly cleaning up unnecessary files, updating drivers, and performing system maintenance can help prevent future issues. If you decide to replace the memory module, make sure to purchase a compatible one with your system's specifications. Additionally, keep an eye on the system's performance after the changes to ensure that the issues don't resurface.
