Problem with frequent BSoDs

[stiv12]

Hello there, I have problem with frequent bluescreen's lately so far I tried reinstall windows, clean the PC inside all fan's etc. BSoD's appear's at playing the games or watching something in flash sometimes even at browsing webs (but those are very very rare).

I tried to check voltages manually here are the resoults:

On line 12V I have 12,21-12,25 V
On 3.33V I have 3.39-3.40 V
5V shows 5.06-5.08 V

I have even tested the voltage under PC stress nothing abnormal.

Are there are any tests for motherboard I can do or something else to check? I have 2 piece of 2gb ram tried them separately and bsods are there, I will do memtest soon.

Memtest86 will be the place to start:

No errors are allowed and you may want to test each memory module separately. Run Memtest86 for at least 7 passes

I did that runned it for 12 hours, 14 passes, no errors. However I checked motherboard's capacitors and they are bulged ,im pretty sure that's the reason of bsods. Do u recommend to buy new motherboard (if yes which one) or give it to specialist to change the capacitors?

edit: wanted to paste link from speccy software but akimset prevent me to do it
anyways my motherboard is P5KPL/EPU socket 775

You will be better off buying a new motherboard. Ebay is a good place to start if you want to find an older motherboard like yours, so you can possibly keep the old CPU and memory
