Windows 7 Laptop - USB/Sound went yesterday, Pink pixels on screen today - motherboard failing?

Hello, I have a Toshiba L505D S5983 laptop (i bought a factory refurb in 2010). Over the last year I upgraded the RAM (3 to 4GB) and Microprocessor (from shipped to AMD Turion M640).

I have recently noticed that the computer displays “low on RAM memory” type errors (baseless since I run laptop in performance mode, kill all non-windows processes on startup ,etc), and there seems to be other slow behavior.

Just yesterday, the sound and USB ports became completely unavailable. In researching this issue for Toshiba Satellite L505d laptops, I came across a thread that describes this as a common issue that may be resolved by resoldering a specific chip: http://forums.toshiba.com/t5/Audio-Sound/no-sound-usb-on-satellite-l505d-gs6000/td-p/172564/page/15

I was readying myself to open the laptop and give soldering a first try, then the computer froze and I did a reboot to notice that pink pixel artifacts are all over the screen. They do not flash, seem to follow/shadow some window borders slightly. Then I got to wondering, do I possibly have a bigger issue?

I did try all other expected troubleshooting – power off / remove power supply; try to update all drivers; try to enable/disable device manager items (ie, Sound drivers don’t even display, HD Audio Controller displays unresolveable error; USB interfaces don’t even display in device tree); I did a system restore, I booted in safe mode, etc.

If anyone has a gut feel on whether this is a broader issue (such as - motherboard is probably “totaled”, could it possibly be hard drive related?), or suggestion on something else I might try, I would be most grateful!

Thank you!

It could be, daverf. It's almost impossible to tell with the motherboard sitting in front of me without knowing the intricacies of motherboard circuitry, let alone over the internet. Sorry that I couldn't be of much help.

The next thing I would do is take it to a local, reliable, PC-repair shop to get it evaluated. Personally, I've dealt with a few in my area, so I know which ones will give their all to fix it, so hopefully you can locate one that will do the same.

You could also get in contact with Toshiba, but they might not even look at it, since you upgraded the processor.

I probably won't be able to solve this issue, but are your sure the CPU you installed is 100% compatible? How long after the installation of the new CPU did it take for these problems to arise?

Are all your RAM sticks rated for the same frequency and timings?

Hi ihog, thank you for taking the time to review/reply. I did order the manufacturer-recommended DDR2 RAM specs (2x2G), and these were installed over 5 months ago. As for the CPU - I did think the CPU would be fully compatible - I googled to research- I'm a tinkerer, not an engineer, so maybe this could be part of the issue? The before/after processors are AMD Caspian units - specs below). What do you think? These problems seem to have a more sudden, recent onset.

Model number Frequency L2 cache FPU width HT Multi1 TDP Socket Release date Order part number
Athlon II M300 2000 MHz 2x 512 KB 64-bit 1600 MHz 10x 35 W Socket S1g3 September 10, 2009 AMM300DBO22GQ
Turion II Ultra M640 2600 MHz 2x 1 MB 128-bit 1800 MHz 13x 35 W Socket S1g3 September 10, 2009 TMM640DBO23GQ

Again, I appreciate your time.

No problem. In terms of TDP and socket, the new CPU should be compatible, but laptop motherboards tend to be finicky. But, the fact that the TDP and socket are the same and that it's been five months since you installed it, I don't see why it'd be the issue.

I got nothing except try a fresh install of Windows. Sorry, mate.
