Ok recently I upgrade my bios with the latest update version as usual. But this time I forgot it reset all my settings. So now when I am on my computer it could be 30 minutes or a few hours my monitor says NO SIGNAL and goes black and I gotta reboot my computer. I got a couple things in my bios that I don't know what they do and what I should set them to. Your advice is greatly needed as I try to trouble shoot these problems. MPS REVISION: CHOICE 1.1 or 1.4 ICH DELAY TRANSACTION: ENABLE OR DISABLE SPREAD SPECTRUM: ENABLE OR DISABLE PCI IDE BUS MASTER: ENABLE OR DISABLE ALLOCATE IRQ TO PCI VGA: ENABLE OR DISABLE SUSPEND MODE: AUTO or S1 (POS) ONLY or S3 ONLY REPOST VIDEO ON S3 RESUME: ENABLE OR DISABLE ACPI 2.0 SUPPORT: ENABLE OR DISABLE ACPI APIC SUPPORT: ENABLE OR DISABLE BIOS-AMI ACPI TABLE: ENABLE OR DISABLE My hardware specs are ASUS P4C800-E-DELUXE P4 3.0 GHZ 800 FSB with H/T ( NO PRESCOTT) 2 sticks of KINGSTON DDR 3200 512MB 2 RAPTOR 36 GIG DRIVES SATA RADEON 9800 PRO 256 MB SOUND BLASTER AUDIGY 2 PLATNIUM GIGABIT ETHERNET CARD DAZZLE CREATIVE CAPTURE CARD PIONEAR DVD-R 2X burner TDK 48 X burner I was curious if anyone could point out why I could be having these reboot/ monitor going out problems, they only started recently, my monitor goes out if im browsing or sometimes just idle. I could turn my monitor off leave my computer on for 5 hours, I turn it back on signal is lost. I used DIAGNOSTIC with SYnamentc and it said my hardware all good so I got a feeling its a bios issue since all my settings got reset. If anyone can point out what those settings do and what I should set them to , please help me. I greatly appreciate this , and this problem has been causing me a ton of headaches.
