some additional details: EVGA 500W bronze PSU, 2x4gb corsair ddr3 1600, and a 120gb SSD. everything works absolutely perfect when the pentium is in.

I agree with your assessment. If your bios is version 1.5 or newer, it should be working so it probably is a DOA. Now, just for fun... clean the bottom of the CPU with alcohol and try again.

Might be doa, cleaning under side of cpu is a good suggestion.

Something you can try too if you haven't yet is with the Pentium chip installed, boot bios and load defaults, power down then clear cmos.

hey guys i looked and it does look like there is one bent pin on the socket, would this cause the weird behavior listed above? i will attach a picture in a bit. would a bent pin make one cpu not start at all and the other one start but be really unstable and then stop working?

Bent pin can cause all sorts of problems though this must of just happen swapping cpus around because your system was running fine before all of this. Think the case of the 4690k migjt have been the case of cmos not cleared properly. Wouldn't know for sure unless you can straighten that pin and get your Pentium running again without problems.

Use a credit card cross ways to straighten the pin.

Problem Solved!!!Sorry for not posting earlier but i wasnt able to look into it cause of work.I did what the clear cmos guide said and it worked.I dont know for sure what i did wrong the last time but my best guess would be not pressing the power button after removing the battery.Thanks to the administrator and everyone who helped .Have a great summer!!!
From this guide: https://forum-en.msi.com/index.php?topic=31222.msg178956#msg178956

New cmos clearing method = motherboards with a clear cmos button rather than a jumper.

Cmos battery is still plugged in. Make sure the jumper in the original position is off the pins if you're going to short with a screw driver.

Just had a look at the manual online, can only see one jumper so what you did was right. Bummer.

You flashed bios to v1.9 yeah?

Maybe flash again with the pentium cpu, once done power down and disconnect power cord and hold power button for 10seconds to discharge remaining power from caps. Reset cmos, short pins with battery and Pentium cpu still in. Enter bios and load defaults with the Pentium.

Power down and try the i5.

one thing i have noticed is that the when the pentium is in, the cooler always starts, stops, starts again, stops again, then starts full speed and the rest of the pc comes on. not sure if that means anything though. updating the ME right now, after it is done ill try what you said

Latest bios version contains all modifications prior so shouldn't make any difference but you can try.

Has the fan always done that? It may just the board checking the cpu fan before the system powers on.
