I bought i5 2500k, i replaced the processor, but the screen was black, nothing happend. I did the CLRMOS thing, still nothing. after a while, i got a blue scren with PC NEEDS REPAIR. then i remember i still got the USB with windows on it. i tried to boot the stick, but when i restarted the PC, a little smoke came out of the motherboard and whenever i try to power on the PC, all the fans spin a little, then stop and continue doing this until i unplug the power cable. Do i have to buy another motherboard?
[1] TDPs are different... 65W against 95W, which does mean that you probably installed new heat sink and new fan on the top of the new CPU, but also you should recalculate PC's power budget since the new CPU adds to the old power consumption additional 30W (this smoke you experienced could come out of PSU, at the very beginning of Power On).
[2] I noticed that on-board GFX is different: Intel® HD Graphics 2000 against Intel® HD Graphics 3000, so you have to ask shop you bought new CPU out from, do you need new BIOS (probably you need to have new vBIOS component, which is part of overall BIOS). :grin:
Please, do forget what I wrote in [2], Feeder... Please! :angel:
If you go for replacement mobo, just be ensured that you have the latest BIOS programmed on it. My best guess, this BIOS should work for all intended CPUs on this board (so vBIOS is kinda generic one with different options depending upon CPUID, fitting for all on-die GFX). I would not explore this deeper (it is matter of completely different dimension). :whistling:
One more thing to advise: please, ensure that your replacement CPU is tight placed in the old mobo's socket (but NOT too tight). Maybe, after all, you have problem with some CPU pins having loose connections with mobo?! Please, try to re-seat CPU once again and see/experience the effect. :grin:
Only one way to find out. Test it on a compatible, known working motherboard. CPUs do die occasionally, so we cannot rule it out entirely until tests are done. A faulty board or psu will easily kill the cpu (and other components). Smoke from any part of the motherboard is a definite sign it's fried and it should not be used any longer. That poses the risk of damaging other peripherals and hurting yourself too.
When you get the replacement board, test the old CPU on it first, just to make sure the board is working, before testing the new cpu. It's wise to get a GOOD QUALITY replacement PSU as well. 1000W is overkill, don't you think?
Chief is correct and make sure the psu is a good brand name as 500 watts is all you need in a good quality psu. We like Seasonic, XFX Super Flower and Antec HCG as well as some models from Enermax and Thermaltake.
I am going to buy Seasonic S12II-620 Bronze 620W.
And this motherboard Gigabyte GA-B75M-D3H.
Is the motherboard pretty good? Since it has USB 3.0, socket 1155 just like mine.
