Distorted POST screen

hello,i'm having a problem fixing an old pc.

sorry i forgot to write down the specs,but it something like ami bios(default time setting is 1988)
not so old CPU
samsung on the post screen....


case: distorted bios screen
=unplugged and plugged the memory then it works but problem persist after rebooting.
so i recommend them to go to a pc repair shop for diagnosis, maybe it's on the mobo or ram.
=it's the RAM. But the owner can't afford the service price.

case2:
1.replaced the RAM and it worked fine,I format and reinstall the os but after that ,the OS's screen resolution cant change to 800x600.

2.upon rebooting, i cant acces the OS, it just load then a black screen.



what seems to be the problem?is it the bios(outdated),battery.harddisk or what..?

,THANKS!

[Do you mean you tried to change it to a resolution higher than 800x600? 800x600 is the lowest XP can go I think.

I hope you've loaded all the drivers (hunt them on Internet for latest) after a clean install of the OS. If you didn't then you're looking for trouble.]


it's a CRT monitor.

i meant i tried to change the resolution from 640x480(4 bit only) to 800x600 but it cant.I'm just confused because in normal installations, it's not just a very poor 4 bit resolution.
-okay, i'll try for the drivers.


replacing the RAM solved the distorted post screen.
