Hello. I bought a new CPU E7500 for my home PC and I'm having a problem that won't let me sleep. After installing the new CPU my Sapphire HD4870 won't send any signal to my monitor, unless I manually turn the PC off by pressing the power off button for a few seconds. Turning the PC on after this action would result in a normal booting. This way i could play for hours and the PC it's been on for 3 days now with no problems. So after any restart or shutdown from software, won't work. I used the HD4870 with my old CPU E4500 and there was no problem. I also tryed the new CPU with the old videocard and it didn't work so the new CPU is the problem for sure.

Thanks in advance.

Btw this is the configuration I'm using:
CPU: Intel Core 2 Duo E7500
Mobo: Intel DP35DP
Video: Sapphire HD4870 1gb (standard one)
PSU: Gembird 650W
Memory: 4Gb (4x1Gb) DDR2 Pc2-6400 (400MHz) Kingmax
Monitor: BenQ 2420HD

According to Intel, SLGTE requires minimum BIOS version 0345 and SLB9Z requires minimum BIOS version 0484. If your BIOS is the minimum version or newer, then you should contact Intel support.

BIOS version is DPP3510J.86A.0572.2009.0715.2346 acording to CPU-Z. Not sure what this means as I'm not that good at this stuff, but BIOS release date is 07.15.2009 so it's quite recent if you are asking me. I guess you are right and I have to ask Intel for help but I don't realy espect any as the Mobo is quite old, unfortunately.

Thanks alot for your answer.

I checked and it's the latest BIOS version for my Mobo but only for WinXP and WinVista while I'm using Win7. Should this be the problem?

Win7 probably isn't causing that issue. If there's a setting in the BIOS to set the default video to PCI or PCI-e, then make sure it's set to PCI-e. Is your motherboard more than 3 years old?

I found the BIOS setting, it was set on default, now its on PCI-e but still nothing changed.

In what regards the motherboard it's been exactly 3 years since i bought it. The model must be a little bit older of course, so the answer is yes, it's older than 3 years.

I would still contact Intel and report the issue. There isn't much else that you can try.

Thanks alot for your answers.

VICTORY!!!
I downgraded BIOS from the latest version to the minimum required version 0484 (usaing the old CPU) and now everything works as intended. :o 
I have no idea what the reason is but i don't realy care :D  ... it's working and I'm a happy-happy panda!
I can only guess that for old motherboards the latest version of BIOS is not always the best.

Cheers!

There's a bug in the new BIOS that should be reported to Intel.
