Windows 7: Repeated crashing, possibly faulty power supply?

I replaced the power supply (my manufacturer said I could do this so long as the PC wasn't damaged in the process) and it hasn't crashed on me yet. However, about a week or so before the crashes started, I started getting random lag in games that up until then ran beautifully. Really really bad lag spikes that would make the game basically unplayable and could last for minutes at a time. I tried a less demanding game last night and I heard coil whine, and every so often the coil whine would stop for maybe half a second and while it was stopped the game would lag for that instant. I'm currently wondering if this could all be cat hair building up in the card but as I understand it the only way that would harm the card is by gunking the fans and I watched it while it was being stressed: the two fans underneath it were spinning away and my monitoring software was giving me a steady RPM within the min/max. I blew on the card earlier and at least externally I don't see much hair but not knowing how it works maybe some is stuck inside and hurting it somehow?

Look in the lower left of this post and you will see My System Specs.

Those are the specs of my computer. They will follow my every post so other members don't have to go searching through a bunch of post looking for them.

Following the tutorials I posted gives instructions on just how to do that.

I filled that in and here's the snapshot link if you would also like to see that: http://speccy.piriform.com/results/e...dTBDekL5ilWy0U

Vacuuming the card did not help.

What I noticed in the speccy log was that you have Windows Defender and Firewall active at the same time you have Eset anti virus and firewall active.

If it was my computer I would disable Windows Defender and firewall and just use Eset.

Have you checked you cpu and gpu temps under load? If so what where they?

What cpu cooling do you use?

Because I can't hear what you are calling coil whine I really don't have any suggestion except do you know where the sound is coming from?

It's possible that the under powered power supply has damaged the card at this point I would contact the place you got it for warranty repair.

Thanks guys, I think swapping the PSU fixed the problem and while it may have damaged the card some I turned the GPU's fan speed up to 70% instead of the default 43% and things are running fine now. I'm thinking mailing it back would just put the computer through a bunch of trauma and I plan on upgrading the card in a year or two anyway so as long as it's stable I'm happy.
