Motherboard

hdd

vga
sapphire radeon hd 4670 1gb ddr3

OS: windows seven ultimate, 32bits

Now, the problem

The computer works splendid, even though the system doesn't recognizes the 4 gb of RAM (yep i know i need a 64bit os), but suddenly it shuts down, specially when playing warcraft III w/o patch. The screen displays a huge mess of pixels and the speakers sound like hell. Then appear a blue screen that i can't read and the computer reboots.

This hasn't only happened when playing. Last time i was just listening music.

What is this about? hardware? software? both?

Please HELP!

Sounds like your RAM needs more voltage. Take a stick of RAM out it should stay on the sticker the timings and the voltage needed. Go into BIOS and see if it needs more voltage.

What are your temps?
You could also have bad RAM; use memtest86+ to test your RAM.

What if my BIOS doesn't let me change the RAM's voltage parameters? I tried, and the only options it gave to me were clocking and overvoltage. Should I try using the dimm slot B instead?

It should let you view the Voltages, Tell me what you see when you enter BIOS. Word for Word.

Hi again!

Let me thank you for the time you expended trying to tell me what to do, and obviously, the help you gave me. Actually, I checked the BIOS, and the voltage was Ok. The matter was that one of the RAM cards was bad. I tried using the RAMs I bought separatedly: one was OK, the other... I'll have to make use of the "lifetime" guarantee. Anyway, your help was indispensable to find out what was wrong with my new PC.

Thanks once again
