Boot up 3 times @ 800x600, 4th time at 800 x 480???

**RedGTiVR6** · 08-19-2008, 07:51 PM

For the life of me, I can't figure this out.

I recently purchased a new motherboard for the car: Intel DG45FC

I purchased it because of the new audio chipset that it has. This board is supposedly designed with home theaters in mind. I can say that this chipset, over optical out, sounds a lot better than my iBase MB899.

More dynamic and a lot more drive. All good there.

I have one major problem though.....

It seems like 3 out of 4 times when I boot up, the computer will boot to the desired resolution: 800 x 600

The 4th time, it will boot to 800 x 480.

If I go into the Intel Graphics Media Accelerator Driver panel, I can see that 800 x 600 is already selected...there is no option for 800 x 480.

95% of the time, I can fix it by picking 800 x 600 from the drop down (even though it's already selected) and hitting apply.

I have installed two different sets of drivers.

The ones that came on the CD, which were dated 7/something/2008, and ones from the web site for the graphics chipset, dated 6/10/2008.

Neither seems to work.

Anyone have any ideas what might be causing this?

On a suggestion I tried the following:

Persistence Mode driver (igfxpers.exe)? Just a thought.

Open Regedit and navigate to

HKLM\Software\Microsoft\Windows\CurrentVersion\Run

Find the entry for "igfxpers.exe" and delete it then reboot and see if that helps.

However, on the second reboot, I was back to 800 x 480...so no go.

is your screen turned on each time?
and do you have the igfx or whatever it is starting on boot?

seems mad that it dosnt stay the same...

The screen turns on with ignition....

right now though, it turns on, then off, then back on, then the computer goes through boot. I am running an M4-atx on the 1.0 firmware. I will be reflashing this firmware this week though. Wonder if that order might be messing things up some?

As for igfxpers.exe, I don't know, but that's a good question. I'll check that....will have to be tomorrow most likely though.

I did check to see if igfxpers.exe is running on start-up.

It is not running on start-up when it starts up at 800x480 or 800x600.

The only thing running is igfxtray.exe

You may want to try editing the driver's inf file and remove the 800X480 entry, if it is possible for this version.

Ever figure this problem out? I'm actually looking for a reverse solution... how do I get this mobo to boot only to 800 x 480. I havn't had any luck with that res at all.

changing processors solved it for me strangely enough.

**galvitron** · 09-17-2008, 11:41 AM

^^^ That is weird...

**RedGTiVR6** · 09-17-2008, 12:17 PM

EXTREMELY strange....it solved a number of other issues too...like windows randomly not finding a boot device.

I dono if it's a bad processor or what...
