Motherboard: Gigabyte GA-G31M-S2l (BIOS f8b - stock)1
Processor: Intel Core 2 DUO - stock cooler
PSU : CoolerMaster eXtreme Power Plus 460W
HDD: 1 x 640 GB SATA, 1 x 320 GB IDE
RAM: 2 x 2GB DDR2 GPU: OnBoard
Everything is on stock.
The artifacts/Scrambelled screen comes up anytime after boot. even when I am in BIOS Settings.
I have the following sensors that monitor temperature
CPU : 35
CORE #1: 50
CORE #2: 50
HDD1: 39 HDD2: 36
What could possibly cause this issue ?
Can this be because of a underpowerd system? I had once given My PSU for RMA(and they gave me a repaired one after a week and from its serial no I can tell that the one they returned wasn't mine) so I doubt its output.
can it be because of high CPU temperature? I had this problem when I just turned on the PC with CPU at 46 C
I have tried :-
- testing one memory stick at a time as mentioned here but that doesn't help..
- Cleaning the dust on the board and CPU fan (without removing it)
- reducing the HW to minimum
- memtest86+ v2.6 - completed without any error temperature of CPU just after memtest was 65 C
- reassembling the system.
But none of them helped..
Updating drivers is not an option as this thing comes up before booting into OS.
BIOS version is f8b(stock) I haven't added any HW and the system was running fine for the past 3 years.
