Frequent Blue Screen errors Windows 7

[Mercer_1]

I've been having frequent bsods recently, not sure what is really causing it. bsod displays uncorrectable hardware error and i tried cleaning the components, replacing thermal paste of the cpu, tested the hard drive and ram it was okay. sometimes the pc would not crash for a day, sometimes it crashes immediately after booting. The pc is a desktop.

pc specs: (acer aspire m3970)
cpu: intel i5 2300
ram:8gb 1333
mobo: oem acer
psu: delta electronics 300w 80+ bronze
gpu: zotac gtx 1050 mini 2gb
windows 7 Ultimate 64 bit

That is a very weak PSU, maybe its failing.
There are also forums that analise your dump files.

they system bugchecked because of a error detected by the cpu
the error is typical of a overheating problem. check that the cpu has proper power levels and that the fan is still spinning up. I would also do a visual inspection of the motherboard for failed capacitors (swollen or leaking brown fluid) check the power supply voltages and make sure the fan is spinning if it has one. blow out dust if you have not done so already.

it will help your virus scanner work better.

see if you can find a bios update for your motherboard, get the newest one, try to find one newer than 4-1-2012 so that your usb subsystem will work correctly.
