3.6ghz e8400 worked before. Why not now?

[carrot1401]

Got my e8400 and Gigabyte P35-DS3P rev1.1 with 4gb of ICZ PC-6400 and was excellently stable at 3.6ghz (400x9), yet now when I turn the PC on, I get one long beep followed by 2 short ones before the PC turns itself off and reboots with default bios (333x9)

Any ideas as to why it last perfectly fine for a whole day at 3.6ghz and even ran Call Of Duty 4 fine, yet now won't work? And I couldn't find the beep code definitions in the manual, can someone explain that error sound to me?

The beep code is normally specific to the bios , not the motherboard, therefore find out what bios you have (American Megatrends, etc) and google for that.

It is Video failure I'm sure. Try taking out the graphics card, replacing it and reset the CMOS on the board.

If you still get it then maybe something is wrong with the Graphics card.

Did you overclock your gfx card?. If you still have the X1900 then try clearing any dust build up that you can see.

The above post seems you're having some graphics issues .

Must admit I have noticed temperatures seems to be a couple of degrees higher on the gfx card recently (its a HIS x1950 pro). Its wierd that setting the cpu frequency affects it though...
I've tried setting PCI-Express speed to auto or the normal setting (100mhz I've been told, please correct if wrong.

As for that COD 4 problem, it only happens on that game, Sega Rally and co is fine.

indication is it doesnt like the overclock if it resets the bios back to 333.

when you ran the overclock at 3.6 had you rebooted it prior to switching off the night before you had the problems ?

try the pci-e at 101.
