How to restore default BIOS settings on Toshiba 1410 / 1415 / 2410 laptops? Option to CHGBIOSA?

Question

I  have problems booting to any operating system but DOS on Toshiba Satellite 1410 (in very good physical condition) after few years of inactivity (drained down main battery and CMOS battery - now they're charged)
Windows stops with BSOD (error 0x0000008e), Linux stops with kernel panic, bad_area_nosemaphore and IRQ error.
Plain MS-DOS 7.10 seems to run OK.
BIOS was 1.40 with main password set. After first boot it displayed request for entering password and pressing F1 key to set the hardware clock. Now it doesn't display this message anymore.
Two memory modules (Nanya - 256 MB, 266 MHz, CL 2,5) are OK - checked on different versions of MemTest86+
(Windows Memory Diagnostic Tool hangs when starting!)
I dismantled laptop and cleaned very small amount of dust inside with compressed air.  Changed thermal paste on the processor (Celeron M 1,8) and bridge. Turned laptop on with extension cards, battery and disk and without them also.
It didn't help.
I flashed the CMOS with BIOS 1.20, 1.30 and 1.40 back again. None of the versions didn't let booting neither Windows nor Linux.
MS-DOS, PC-DOS, FreeDOS still run OK.
What's more interesting - after flashing procedure all BIOS settings were intact (booting priority, battery saving mode, etc.). And yes - I removed the password before flashing!
I was suspicious about problems occuring when laptop was entering 32-bit mode and checked it with Video Memory Stress Test.
When CMOS was flashed with 1.20 BIOS above test was running flawlessly. However, with 1.30 and 1.40 version it stopped >>Unhandled Exceptopn "Access Denied"<< in 8th iteration when lucky. Most of the time it stopped after 2nd or 3rd iteration after framebuffer subtest.
So my question are:
- did CMOS lost its settings or somehow they were corrupted after long period of laptop's inactivity?
- is Video extension of this BIOS flashable?
- why the settings are NOT restored to defaults after each CMOS flashing?
- or maybe there is some hidden switch/option to CHGBIOSA flasher to reset non-flashable CMOS area?
- or is my built-in Video Card (nVidia NV17M) or IRQ enumerator dead?

Hi Jerry! I think I'm on board now, anyway I hope so. I removed both devices and switched them around. The device manager shows two USB devices. One is Mass Storage and one is Composite. I don't realy know which one is the 1TB and which one is the 16 GB. In my boot menu, it just says USB now?? My laptop only has three USB ports. Two on the right and One on the left. I have a wireless mouse plugged in one of the ports on the right as you can see in device manager. I hope this is what you were asking. I can be a little thick headed at times, so let me know what else you want me to try Thank you for your kind reply. It really means a lot to me.
Dokie!
