Hi everyone, and thanks in advance for helping.
I have a Toshiba Satellite P205D-S7436 here. CPU-z reports the following specs:
CPU name: AMD Turion 64 Mobile TK-53
CPU specification: AMD Athlon 64 X2 Dual-Core TK-53 1.7GHz
Motherboard: Toshiba JASAA 1.0 with ATI chipset RS690/RS690M and Southbridge SB600
BIOS: Toshiba V1.4 (2/25/2008)
RAM: 2 Gig of DDR-2 (original)
Video: ATI Radeon X1200
OS: Fresh install of Win 7 Ultimate x64 SP. 1 fully updated
The issue is frequent screen lock up. It does not go to BSOD, but simply stops. So the screen displays a frozen snapshot of the moment of failure, and the PC will not respond to input from mouse or keyboard.
Things I have already tried:
Ran memtest all night with no errors.
Looked at mfg website for drivers
. None seem relevant to the hardware, so I just went with what Windows Update provided.
There is one error in Device Manager. It's for USB mass storage device. There is a physically damaged USB port on the machine. Looks like it was mangled at some point in the machines life when someone tripped over a cable and yanked it out. Computer owner reports that this occurred a long time ago and the machine functioned normally for a long time after that.
There are numerous entries in event viewer. I don't understand what any of them mean. (can provide dump file to anyone who would be kind enough to help educate me.)
HWMonitor reports no information as to GPU temperature or Fan speed on this particular hardware, but unit does not feel excessively hot, and I believe I hear fans and I feel what I guess is an adequate amount of hot air coming out.
I have a lot to learn about this stuff, but the reading I have done so far suggests this is likely a heat issue and leads me to the conclusion that my next step should be disassembly for the unit to look for obstruction of airflow or a poorly seated GPU heat sink. I'm hoping someone can tell me something I've missed or help me gain some insight from the output of Event Viewer before I go to that option.
