I have a PII 400, 64MB SDRAM, Intel BX chipset, and the Viper v550 AGP version. Everything works great! BUT.... this morning, I went to turn it on, and the monitor gave this high pitch squealing noise, and the picture was totally screwed up(from the startup "DOS" screen, all the way into windows). It looked like an old TV stuck on horizontal scroll or something. Anyway, has anyone else seen this happen? It was just fine the night before! I waited a couple of hours, and what do ya know - it worked fine! I was thinking that it might have something to do with the power supply not having enough watts. OR maybe the memory? If anyone has any ideas, please let me know. Thanks!
