Hello people.
I opened up my Compaq Deskpro EN SFF to clean the dust inside.
After that, the hdd wasnt detected anymore, and when I entered bios, the pc froze while I entered the bios and looking, in bios, for ide devices.
I replaced the hdd with a known good working one, and it was the same. Then I resitted the ide and molex cables, and the new hdd is detected again. Probably the cables were not making good contact.
BUT, now I get at Compaq splash screen some corrupted charectors, like in that picture.
The pc works well with Windows 98. I played, for a few hours, Tomb Raider 2, Quake 1, Heretic 2, Quake 2, NFS 3, Motoracer 2. No coruppted textures or anything strange.
I tested even Quake 3, at very low resolution and crapy low textures, and is stills get 14 fps. Is working, not playable. But that is just the limitation of the ATI 3d RAGE PRO.

Has anyone encountered this corrupted charectors in bios splash screen? Should I be worried? I found a Bios for this compaq variant 686T5. Should I try to reflash the bios?
