Trying to find out what the hell is wrong with my PC

Sorry for not being able to shorten this, I don't know how. Please understand and help me.

My PC:
PSU - Sirtec High Power Element BRONZE 500W
Motherboard - GA-G41M-Combo (rev. 2.0)
CPU - Core 2 Duo E 8400
RAM - 8GB DDR3 Corsair
GPU - (second hand) ASUS GeForce GTX 560 Ti DirectCU II Top
HDD - Seagate Baracuda 1TB

Short history on my graphics card, I had an old one, a GTS 250 that went kaboom so I bought a replacemenet Second Hand. The GTX 560 Ti was a steal, and I bought it from someone who agreed to all my tests and conditions, even have a copy of his ID. Had issues with it's driver, reverted to a known stable driver. I knew my PSU couldn't really handle it so I underclocked it to factory and undervolted it to 0.950V. With a few hours in the donut of death and Unigine Heaven I can safely say it is stable.

Now for the actual reason why I am here. I have been having weird freezes, even before tinkering with my GPU. I tested CAPSLOCK, it was frozen. I noticed that this happeened when I had a few things open and tried to also open Malwarebytes. I also have an anti-virus (Avira) so I figured that they had problems with one another so I made exceptions for each other in both programs. Freezes dropped a little after that. Fast forward to today where my computer simply refuses to boot properly, I boot but can't click anything other than open desktop folders, but can't run any programs. It was getting annoying at this point so I rebooted into safe mode and got rid of Malwarebytes completely. Eureka, it boots. Everything works well until I want to install a game one hour ago. System slows to a crawl but not in the normal way but takes years to respond. Task Manager - not responding, writing a word in search, first two letters written instantly, rest of the word, after 15 seconds, open a new tab, write an address and press enter - instant, but it doesn't show any loading, it just loads it after a minute. While everything is slow as hell I can still watch and pause the video I loaded on youtube, no issues. To top it all off I can't even install the damn thing, it always gets stuck, installing anything does that. I restart and things seem to have come back to normal, but I'm not trying my luck anymore.

Problem with this whole ordeal is - I just don't know what to test anymore, I tested 2 weeks ago (my issues started more than a month ago) 5 hour Furmark and 2 hour Unigine Heaven on my GPU, nothing. Prime 95 SmallFFT 5 hour and Blend 4 hour on my CPU, nothing, MemTest 86+ for 6+ hours on my RAM (did another run 4 months ago when my previous graphics card was behaving weirdly for 11 hours) nothing, HD Tune Pro - no errors, and error scan - nothing, Speedfan shows no smart errors either. Temperatures look good. I just don't know what to do next ? I can't even afford to get my PC diagnosed by a specialist if I am to buy a new component for it since I couldn't afford both. What do I do ?

I think your psu is giving out. Also even with underclocking your card (don't recommend it) your psu will probably fail to give it enough power. I highly adivce you get a new quality unit.

I can afford a cheap 600W PSU. It has good reviews, good rating and 3 year warranty which is enough for this old system even if cheap, but I have to ask, are you sure about this ? I really can't afford to replace something that might not be the problem. Is this how a defective PSU behaves ?

As I said I tested my hard drive with HD Tune Pro, no errors, no problems in SMART, same reading from Speedfan, no errors in SMART, just downloaded Seagate Baracuda software, no errors in SMART, will perform some tests, but given everything until now I know the answer.

As for Event Viewer last 24 hours I have a few Critical Errors, Even 41 Kernel Power, but I think these are from me pressing the restart button when my PC froze. Error I have 73 - Event 7001, 4 - Event 7022, 2 - Event 7034, 1 - Event 7043 all Service Control Manager, 1 - Event 20227 RasClient, 14 - Event 10010 DistribuitedCOM.

Update - Scanning the drive with the tools from Seagate and running an sfc /scannow I got the same behavior as earlier. Huge delays in actions.

Edit: My PC doesn't seem to like performing too many actions at once. Never had an issue until now.
 


A defective psu in its early stages will make the pc bleuscreen, turn off, give a black screen, make it fail to boot, freeze, etc. However these can also point to a defective hdd. The only real way that you can be almost certain is to make your pc run full power (no underclocking) by using furmark and prime 95 and seeing if it suddenly shuts off. If so then most likely the psu is dying of not then the hdd might be the dying part. Btw what 600w psu are you talking about? Because unless it is from a proper brand cheap 600w psus may only be able to deliver 200w of power or less.

It's a Segotep SG-D600SCR. 85% rating. 3 Year warranty. I really can't afford anything bigger, as the next option that has good reviews, has protections and is rated by the seller as being appropriate for gaming (not really, but those rated as such aren't as bad as those sold for office workers) costs 50% more. Here is the place from where I'm buying it - http://www.pcgarage.ro/surse/segotep/sg-d600scr/

Also, I just plugged in my old faulty PSU in this PC (it had problems with shutting down so I changed it to the current one) and guess what I found - YOU WERE RIGHT ! Had an error test running in HD Tune Pro, had my browser open, a movie open, CristalDisk and GPU Shark open, ran a sfc /scannow in elevated command prompt, all at the same time and it didn't slow down to a crawl... I can't believe that the sfc /scannow didn't take an hour to go from 87% to 97% and then proceed to get stuck. Pretty much seals it, I'm buying a new PSU.

I'll wait for your opinion on the PSU and I'd also love some advice as to what tests should I run after I get the new PSU to see whether it broke something else or not, I really hope not :((
 


That segotep looks to be a crappy unit. Is there any store you can buy from that has a brand like seasonic, corsair, antec,... even if you were to buy this one it will probably fail soon again or might not even give enough power to the pc.

I asked this on their forum because I needed a fast answer and they pretty much said the same. Long story short, given my inflexible budget this is the option that I uptimately purchased:
http://www.pcgarage.ro/surse/fortron/hyper-600/

I trust those guys so it should be at least an ok option. I thank you for your time and aid. Wish you a nice day.
 


Its bad but it should work for the moment do start saving up to replace it in the near future as it really sin't a good psu.
