My PC Is Broked :(Follow

Sooo, I'm not 100% sure as to the cause of the problem (or what specifically IS the problem) but I'm 99.99% sure that the cause of the problem is from multiple (and very multiple) "power outtages" from the idiot landlord flipping every fuse in the the fuse box because he blew a fuse and doesnt know how to fix it without flipping them all, and each and every time he flips my power off I happen to be doin something on my PC, which doesnt really like it when it suddenly loses all power :(

Now that we know the cause, on to the problem! What is happening is at random times, (sometimes once in a day then not again for a week, other times 2 or 3 times in a row about 30 mins appart) my screen goes completely one color with sorta vertical lines on it, almost always it is a redish kinda color but not solid red, kinda like a fuzy read if that makes sense, and the vertical lines are space out maybe 3cm apart. Last night it went a light blue color once, and then a yellow color once. Im not sure if the color it changes matters, but thought I would throw that in there to give as much detail as posible.

This only ever seems to happen when I am running an instance and there is alot of special effects shooting accross the screen. Based on this I am thinking it is the graphics card which is damaged? Is there any sort of way to run some sort of diagnostics test on my hardware without taking my system into a shop for repairs as I dont have the money to dump into my PC at this time of year. I am gonna try and install my old graphics card back into the computer and see if that solves the problem, but first I thought i would post here about my woes and see if there was any advice that someone more knowledgeable could lend me!

there is the speedfan data... temps look really low is that a bad thing? i live in a basement suite and its kinda always cold down here lol the PC tower itself is rather cold to touch...

i opened the case dusted it out was pretty dirty gave it a brief test run earlier today and ran last half of H SFK without a glitch but still not convinced yet everything is okay just from a cleanup guess just wait and see now?

i have the same kind of problem,and i,m told it is outdated drivers.have you checked to see if all your drivers are updated.for me i need to update the pci bus driver and a video card driver. hope this helps. some times it is the simple things that get us .

What Video Card, what CPU, and what is the rating of your Power Supply? How old is the Power Supply, and do you know if it was 80+ Certified?

Power Supply is something often overlooked these days. Wasn't always a big issue, but the newewr cards are so power hungry. If your video card isn't getting enough juice, it can cause all kinds of weirdness when it is under stress. If your PSU is marginal for your setup, it could have been dying a slow death from peak overloads, and spikes from someone tripping fuses would just amplify that issue (and might be something to bring up with your landlord--ie, he is damaging expensive electronics...label the fuses ffs).

Corsair has a page for getting suggestions for PSU ratings. It's kinda oversimplified, but gives you an idea of the ratings you should look for. Keep in mind though that a non 80+ certified model may have dips into the 65% efficiency range (or lower). In other words, a generic 650 watt PSU may only be able to provide a STABLE ~420 watts of power under high stress, where as an 80+ certified (80% efficiency or better) will give 520 watts under high stress. If your rig needs 400+ watts...you may eventually be in trouble with the generic 650 watt model.
