Hi Mick, |
| 43 |
|
| 44 |
one thing, which is able to produce any kind of error except those, which one |
| 45 |
would exspect in a certain context, is a bad capicitor on the mobo (or |
| 46 |
sometimes in the power supply). |
| 47 |
|
| 48 |
If I understand your posting correctly, your PC is not the youngest |
| 49 |
one...? |
| 50 |
|
| 51 |
I had a motherboard, which completly fails to boot the very first |
| 52 |
stages of the kernel boot process, but perfectly runs memtest86.... |
| 53 |
Bad capacitors... |
| 54 |
|
| 55 |
More RAM means more power. |
| 56 |
|
| 57 |
What happens, if you change the RAMS in such a manner: |
| 58 |
|
| 59 |
slot 1 - 0.5G, |
| 60 |
slot 2 - 1G, |
| 61 |
slot 3 - 0.5G |
| 62 |
slot 4 - 1G, |
| 63 |
|
| 64 |
? |
| 65 |
|
| 66 |
Does teh computer have problems after accessing slot 2 or after access |
| 67 |
more than 1G? |
| 68 |
|

Best regards, |
