System Specs:
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: 50HDD1: 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.
or
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.

how long does it take the screen to freeze? since you can pass memtest this seems to be somewhat random. – Baarn – 2012-06-14T18:21:59.373
the first time this happened my system was running for more thatn 24 hours.. But then next day it happened immediately after turning on the system.. – Nikhil Bhandari – 2012-06-14T18:40:40.560
I am now running memtest gain in the usual position of my CPU case.. last time my case was lying horizontally allowing more air to flow in than usual.. – Nikhil Bhandari – 2012-06-14T18:43:46.793
Just curious, is it words getting messed up or colours? 46 degrees is normalish - my systems run at that most of the time. PSU seems sufficient for the specs. – Journeyman Geek – 2012-06-15T01:01:05.100
I just added a snap of the screen have a look.. – Nikhil Bhandari – 2012-06-15T11:22:16.007
are you speaking about scrambled text on screen right at BIOS?
it had happened with me. and i got past it after just taking out and cleaning my RAM sticks.
if you have another working PC, try using RAM stick from that machine... – tumchaaditya – 2012-06-15T12:07:05.407
Yes.. I also suspected a bad RAM at first but I checked the system with one stick at a time and that didn't work... Memtest86+ also didn't give any error.. I'll try testing RAM on a friends PC and get back here.. – Nikhil Bhandari – 2012-06-15T14:33:22.337
What is your GPU? If you are not using the inbuilt one, try using it to see if it is the GPU's fault. – Bruno9779 – 2012-06-15T14:42:48.850
GPU is onboard :| – Nikhil Bhandari – 2012-06-15T15:48:56.643
