Help with crash w/ no BSOD

[jotec]

i built a computer last december and i have replaced a few part and updated drivers but i still get crashes mainly while gaming. some times it freezes and sometimes it restarts no blue screen.

my system
amd fx4100
asrock mobo
sandisk 120 gb ssd sataII
HIS dig 6770
subsonic psu
corsair h60 cooler
gskill 8 gb ddr3 1866 memory

everything is stock clock. i am thinking it might be the SSD. also i dont know whats causing it but my internet speeds are extremely slow. my connect is 4mbps and my other computers get near that this one hovers around 500 kbps.

i replaced the psu from a thortech, rma'd the graphics card, replaced the wireless adapter. i have no idea where to go from here maybe just a hdd to replace the SSD.

freezing and random restarts would either be from lack of power or overheating. I don't think you have a heat issue unless you are blocking the gpu's exhaust or your computer's case is a heat box. My guess would be the psu isn't providing enough amperage to your card.

i though it may have been a faulty power supply as well so i replaced my 650watt thortech psu with a 620w seasonic
my gpu claim to only need a 400 watt psu.
flow is good i have a large case with plenty of intake and exhaust fans. my wiring is tucked.

try these things
1) Update bios(if possible)

2) Clear Cmos, do this if you cant start or have messed with the bios (don’t forget to unplug the computer from the wall and let it sit for few minutes, if you don’t have a jumper than remove the battery make sure the computer is unplugged and let it for about10 minutes before putting the battery back in)

6) Run Burnintest (if possible)

7) If all else fails then try a gpu, Ram, or psu from another computer
Hope this helped!
