First "new system" information: PSU: Tagan 2 FORCE II TG900 900W. Motherboard: gigabyte GA-MA790FX-DQ6. CPU: AMD Phenom 9600 Black Edition. Graphics card:Asus Extreme Radeon HD3870X2 (only 1 card, not two..). HDD: Seagate (cant remember number) 250Gb SATA-II. Memory: Corsair TWIN2X2048-8500C5D (2Gb DDR2, PC2-8500). Problem: I was playing BF1942 until the early morning (and damn, it looks beautiful now!), and then about 4 hours ago it just freaking died . It just turned itself off.. And nothing I do can get it working again, I searched on the web on my laptop (this one) on how to "power up without a computer" thing, found it.. took my multimeter to measure if there was something wrong.. It still didnt power on. It doesnt smell like any blown caps. There hasnt been any thunder or so, so no lightning has struck system. I must inform that it was not connected to a grounded outlet since only the kitchen and bathroom has that.. I talked to my uncle who is an electrician and he was talking about "power spikes" or something (dont know english word for it, too damn frustrated and angry). He said that could be the reason. So is my entire system dead now? Has all of the $$ I spent gone up in smoke?? Cant find words to express how I feel right now... I dont want to open the PSU since that would void the warranty on it. Could it be the fuse? Dont even know where its located.. FFS, why me? Why now?? Why today... However I have the 480W psu from my old system (that is in parts, ready to be sold), is that PSU strong enough to power the system? I mean just to check if the mobo and so on is ok??? I swear, if my system is completely gone... im gonna... Thankful for any replies given..
