So I built a PC 2 months ago and it was working fine but the last one month it started freezing up at random times, most times when browsing. Now it happens all the time I also got one or two blue screens but i didn't write down the code.

The freezes make the PC totally unresponsive, i cant use the mouse or keyboard it never unfreezes and I have to shut it down from power button. Intresting note is that after a freeze happens I check my pc specs and my RAM appears "4 GB(1,94 usable)" form "4GB". I can't find the probem i suspect the power supply from other articles I've read but their problem was not the same.

Things I've tried:
Memtest: No errors
Windows memory diagnostics tool: no errors
SeaTools diagnostics: No errors
Tried re-seating both RAMs and CPU


My PC specs:
OS: Windows 7 ultimate 64bit
Motherboard: ASrock FM2A68M-DG3+
CPU: AMD A8 7650K 3.30GHz
GPU: Nvidia Geforce GT 740 2gb
RAM: G.SKILL 4GB (2X2GB) DDR3 1333MHZ
PSU: FORCE FO19XD 450W
HDD:SEAGATE 1TB BARRACUDA 7200RPM

As LaborinjoRT said reinstall Windows and make sure to install latsest drivers
I had a similar problem and it was the PSU's fault
So if possible try a different PSU as soon as possible

OK, I did a clean install of windows 8.1 and also formatted the hard drive, no crashes yet, everything is working fine but I did order a new PSU with more watt's just in case. I'll post here if anything happens, thanks again.

Changed the PSU with a 600W and it happened again...Right now i would highly suspect the RAM because it crashed twice and after the second crash(both times i had to shutdown through the power button) again it shoed 4gb(1,96 usable) RAM instead of 4gb.

Sounds like theres something wrong with the RAM, im not sure tho
Try updating your BIOS
But remember if your Computer freezes or shuts down while the BIOS is updating, theres a very high chance that your BIOS will brick
What i would suggest is boot to BIOS and leave it for 1 hour and see if it freezes, do that just to make sure the Computer won't freeze during the BIOS Update
Again, BIOS Updating is very risky so be careful
Also is the "4GB Ram (1,96 usable) always there or is it there sometimes?
Please make sure that the ram is not being shared with your Graphics Card or your Integrated Graphics

I've bricked a couple of motherboards due to wrong BIOS updating, the last one I even tried buying a new BIOS for it but even then, every time I turned the PC on it was so crazy, only the cpu fan spinned, the graphics card wouldn't spin or turn on, so I got no image on my monitor and the rest of it didn't work either.

It sounds to me like you have a motherboard problem, maybe even your BIOS. If your motherboard has got a dual BIOS I would try and use that. Watch this video to do so:

Or, try clearing your BIOS by doing what this guy does on this video:

Do what he said,
If you still have the problem then try removing the Graphics Card and use intergrated graphics
If you still have the problem test your HDD
Still have the problem? then the Motherboard might need replacement, it might be the CPU's fault too.

Tried already boot the pc without the graphics card only with cpu's graphics crashed again, so that leaves only motherboard and cpu...but i'm a little bit confused because they are both brand new and they've been working fine for the first month. Could they be faulty from the factory?

Im really not sure since they were fine the first month.
What is suggest is ask for a replacement for the Motherboard and the CPU, warranty should cover you

Hi it could be the heatsink if not fitted properly or the thermal paste if any of those are at fault then the cpu will overheat causing the crashes when idle or full load.

I don't think so because i monitor temp's all the time...no overheating and also I did reseated the cpu fan and cpu.

Its most likely the Motherboard is faulty and needs replacement but it could be the CPU too
Ask for a replacement for the Motherboard first, as i said warranty should cover you

The hdd was not the only probem, RAM is too. I changed the ram with 2x4gb run memtest showed errors, the pc did crashed once with a complete withe screen and one blue screen, both times I had to hard restart the pc BUT once I rebooted the pc I the RAM appeard 8GB(3,96GB USABLE) from 8GB and the strangest thing is that it has not crashed once since then, no blue screens no nothing all perfect and I havent turned of the pc for 2 days to keep it to this condition so it won't crash again. So is it RAM probem or motherboard?

I don't think its the ram since it did the same thing with the old RAM and the new RAM
I say its the Motherboard
