Thread: Windows 7 random collapse

Thus, there is a extreme strangetrouble on my PC. Windows 7 randomly crashes; either on a BSOD,restart or a complete hang up. Although Memtest & Prime95 doesnot appear to display any troubles, I substituted the memory sticks,but the trouble is however present.

As well, later W7crashes/hangs, I require to rebegin the computer several times thusthe system can boot up again. Not doing thus results in no POST andthe RAM led with the MB glowing. My system config can be watched withmy profile.

what are you running - video card brand and model , CPU , m/board , RAM , power supply , brand ,
model , wattage. Examine the listings in the bios for 12v line voltages and temperatures and post them. Run modestest with the RAM 1 stick at a time.

ASUS M4A77T/USB3, Athlon II x4 640 3GHz, 2x2GB Kingston DDR3 1333MHz, ATI Radeon HD4670 1GB DDR3...I am not certain about the PSU, but it is a good one.

I attempted checking with every stick simultaneously a few days ago, but there were no errors. The voltage is 12,376V & the temps feel alright to me.

Remove the case slope and feel at the label affixed to the PSU for the Brand Name & Model Number.
In the Voltages you have posted, (12,376V) could you be more clear with what is what?
What are the brand/specifications of the other RAM you have attempted. Ir is not uncommon for Kingston to have intermittent matters.

Ok, I will test the PSU brand & model, but not today.. The 12,376V is the 12V voltage listed in BIOS. Really the first sticks were Micron and the replacements are Kingston. Their specifications are fairly much the same.

There are no readings for 3.3V & 5V in BIOS. Still, PC Probe reads out 5.07V with the 5V line and 3.31V on the 3.33V line. By the way, now there are few other symptoms. Random beeps happen, the system asks for the MB CD thus it re-flashes the BIOS. I have no clue what causes the trouble. The power supply brand looks to be CCivo, and unluckily there is no model number. The PSU wattage is 500W..
