Black screen blues.

Hi All,

Now where do i start! SO basically i have a 4 year old Alienware that likes to black screen every so often, more than not i will get a single ear piercing beep or maybe i will get looping sound and the monitor will have a flashing power button.

I always have to do a hard reset after this and maybe 1 in 10 of these will give me a long beep followed by 3 short beeps which on the phonenix bios list says its a keyboard error?! (very confusing) then it wont boot at all and i have to hard reboot.

It mainly crashes while playing games(MechwarriorOnline) but sometimes i can be browsing the internet and it will just go black screen. Earlier i was running a mem test and it did it.

I ran the recommended CPU-Z and the GPU-Z monitors and kept them recording just as it crashed to which the GPU reached 79Degrees

The biggest mystery i have come across, well 2 really is that in the bios my PSU is showing a steady 12.01v but in the CPUID screen shot i took you can see it shows 9.200V.......any suggestions? could this be causing my PC to black screen? PLus i also heard that my Motherboard Nvidia 790i ultra, never liked Ram that was under 1.65V but in my bios my ram is running at 1.5v, once again could this cause issues?

I'm looking at upgrading my GPU to a 660GTX ti and maybe my power supply but that depends on what you all think is my issue here.

My PC spec is as follows

Alienware Area51

Intel Q9450
Nvidia 790i Ultra
4 meg DDR3
Nvidia 280GTX
X-FI Fatal1ty sound card
PSU 750watt (no idea what make as Alienware like to strip it all off!)

I hope i have included enough information for you guys and that you can help me with this annoying problem.

Thanks in advance!

I dont see a screenshot (work mighta blocked it) but if you're seeing 9v then you definitely need a new PSU. 11.4 is as low as the atx spec allows.

Hope this helps! one more thing, this may be a small thing but when i boot up and turn my monitor on i get a screen where it looks like someone has just turned the contrast down but with a strip across the screen which is the normal colours i would normally see, i turn my monitor off then back on again and its all back to normal?!

Hi I just copy and pasted, i don't know how to attach shots etc of ym screen! sorry! isn't it weird that my Bios shows 12.01V though and yet the CPUID monitor shows 9.2v ??

I'm confused lol
