Unfortunately I can’t get far enough to do a clean boot before the screen freezes.
I’m wondering if the non-results of memtest would indicate maybe the rams are the main cause of the problem?
I picked up a PC diagnostic card and got this far:
The BIOS are Phoenix, but I can’t get far enough to find out which version.
When I started the laptop multiple times the initial readout on the PC diagnostics card is: 9d55
9D55
9d - Initialize security engine (optional)
55 - Enable USB devices
After the boot cycles pressing S1 the readout are (multiple starts with freezing):
5755 – 569d – 55CC - 588A
55 - Enable USB devices
56 - Enable keyboard
57 - Test for unexpected interrupts
58 - Test for unexpected interrupts
9D - Initialize security engine (optional)
8A - Initialize extended BIOS data area
CC - Redirect Int 10h to enable remote serial video
