Motherboard (Ma790x-Ud4p) Doesn't do the post beep?

[surreal1]

I've had alot of problems with my computer. (Mostly crashes through ANY 3d game.)
On of my friends came over, booted up my comp and said it doesn't post, but it DOES have a post screen.
This sent me wondering, why doesn't it post beep? I'm using the computer right now, and it's running fine, besides
the 3d games crashing with a horrible black screen and a looping music of death. Is the motherboard post beeps (the ones
not happening) maybe affecting that? Or is it what I thought it was and my GPU which I'm replacing soon.
Computer specs are as follows.

Amd Phenom II x3; Current driver
Nvidia (PNY) GTS 250 1gb; Beta Drivers 257.15
Gigabyte ma790x-ud4p; F9 Bios
A DVD Writer/750g @ 7200 RPM HDD;
Antec Truepower-750 750W (Or maybe a PSU problem???)


I'm switching the GTS 250 for a Radeon 5770 soon.

Hi newcomer and welcome to the Tom's hardware forum.

Uninstall the beta driver of ur GTS 250, install the last stable driver and test the rig again.

The beta driver is used instead of the normal one. They all do the same things.

^Maybe do the same thing but don't works in the same way. A beta driver can have some problems and cause some problems to ur rig (if u remember nVidia had some problems with a driver and overheating).

If u want use the beta driver is ur problem, but that could be the source of ur problem.

Nvidia told me to use the drivers. I tried the previous ones, rolling back. Sweeping, reinstalling. It all leads to the same crashing of the computer.

Use driver cleaner (can be downloaded from here) and install the last driver stable version.

If that doesn't help could be the RAM or a not proper installation of the CPU.

Yeah, i've done the safe mode sweep thing with it. If I run prime95 for a few minutes one of the cores workers stops running and the other gives me a weird error such as this,

I read around the internet and it *may* be the problem (RAM). What's your insight on that?

Problems like you describe are often caused by RAM issues. You could either have a bad stick(s) of RAM or not have the speed, timings, and voltage values set correctly in the BIOS. What exact RAM kit do you have?

Confirm that error with SuperPI or LineX.

 

[surreal1]

About the ram I'm not exactly sure (I know it's some sort of Kingston stick.) And I can't find a link to LineX (I'm also not sure how to use SuperPI but from forums I figured you would want the certain time for 1min? Here's what I got for super PI,

Your RAM should have a sticker on it that lists its rated speed, timings, and voltage. The sticker should also have a model number on it.
