Sometimes it would make it to the desktop where there would be a lot more artifacting, in the form of squares all over the place. I would boot the computer again and there would be a message: previous fan failure. I realized the fan in my geforce4 ti 4600 stopped working. The monitor is ok as I tested it on a laptop and it was fine.

I just bought a new heatsink and fan for my gpu. I installed it correctly and applied the thermal paste. The fan is running perfectly and the first time I started my computer it was ok.

I came back to it and it was in sleep mode. I tried to start it again and now I'm having the same problem. The cpu fan is also working. Anything else that would cause this? ]]> PSU and Overheating Issues Frabbi01 http://www.pchelpforum.com/psu-overheating-issues/80988-dell-dimension-8200-overheating.html http://www.pchelpforum.com/psu-overheating-issues/80754-random-shut-offs-now-no-display-boot.html Mon, 16 Nov 2009 02:53:50 GMT My computer was randomly having massive lag spikes when I was using it.

I tried running some cleaning software, and virus scanned it, but everything was clean (took about 10 hours to run everything because my computer was so laggy at this point.)

The next morning I restart my computer and it would randomly turn off, then turn on again. After about 2 hours of this it refused to boot normally. Nothing would show up on the monitor, and the fans would spin on max until i forced the computer off. When I took out the graphics card, the fans spun at regular speeds.

Could this be a processor problem? Power supply? Graphics card?

I have no way of testing the graphics card. I already tried replacing the motherboard but it didnt work (still same exact thing).

I already cycled out all the ram and tested them one by one to no avail. ]]> PSU and Overheating Issues rrigor22 http://www.pchelpforum.com/psu-overheating-issues/80754-random-shut-offs-now-no-display-boot.html http://www.pchelpforum.com/psu-overheating-issues/80619-power-supply-unit-making-clicking-sound.html Fri, 13 Nov 2009 01:59:01 GMT Hello everyone. First off, I don't know much about the guts of a PC, so bear with me.

I'm having a problem with my PSU making a clicking sound. I'm 99% positive it's the PSU.

When the problem first started, it would click for about 2 minutes when I first turned my PC on and eventually stop. Then I cleaned out my PC (I have to admit I smoke near my PC and don't take good care of them.. so it was ugly) and the clicking stopped for a few days.

Then earlier today it started clicking while I was in the middle of playing a game. So I started messing around seeing what I could do to fix it.

Right now I have my PC leaning up against a wall, almost laying flat on the ground (probably bad for the PC, eh?) and the clicking is gone.

I'm thinking the fans in my PSU need to be cleaned. Is it alright if I open it, or should I leave that to someone that knows wtf they're doing? :p

Or could it be an entirely different problem? ]]> PSU and Overheating Issues Mime Victim http://www.pchelpforum.com/psu-overheating-issues/80619-power-supply-unit-making-clicking-sound.html http://www.pchelpforum.com/psu-overheating-issues/80498-my-pc-restarts-when-i-game-overheating-power-supply-unit.html Tue, 10 Nov 2009 10:02:05 GMT Hello im new to this website i have a overheating or psu problem i believe and i hope this is the place to post Ok here is the deal: Whenever i... Hello im new to this website
i have a overheating or psu problem i believe and i hope this is the place to post
Ok here is the deal:
Whenever i play demanding games such as call of duty 4, prototype, oblivion, fallout 3, farcry 2...my computer shuts of and turns on again after 5 seconds. I do not get any blue screen or anything. Only when i restarts it asks if I want to start normally or safe mod and such.By the way, the pc shuts of and on after from 5 to 45 minutes of gaming.

Ok the only things that I think can happen are:

CPU overheating issue
Video Card overheating or malfunction
Power Supply Unit not doing the job right

I posted this problem in another site and they were not sure which was my problem. Ok here go the specs of my machine:

Processor: Intel 2 core Quad Q9550
Ram 4 GB
OS: Vista 32
Video Card: ATI Radeon HD 4800 series. 1 GB
Motherboard: Asus P5Q-E
Chipset: P45
Hard Disk: 1500GB
630 watt power supply and the brand looks like ZION (a no name brand i guess).
Ok and here are some temperatures, and amperages:

idle:
Processor: 36C
Mainborard:43C
Power:25C
Core 1 :46C
Core 2:43C
Core 3:42C
Core 4:42C
Hard Disk: 38C
Video Card: 85C!!!!!!!!!!!!

vcore:1.1V
+12V:11.3V
AVcc:3.3V

and in pc wizzard 09:

voltage cpu: 1.09V

+3.3V:3.26V
+5V:6.12V

video card amperage : idle 30A


Gaming :

video card:51
processor: 35
mainboard:38

cpu:54
Aux/Power:26
HDO:34
Core 1:67
C 2:59
C 3:64
C 4:65

Voltages (Volts):
Voltage CPU:1.06
+3.3 Voltage:3.28
+5 Voltage:6.12
+12 Voltage:11.30

video card amperage: from 43 to 45A

Ok something else. Like all, i noticed the high temperature of graphics card, even idle. I checked and i saw that the fan was at 20% capacity. So i changed it, and after this change the idle temperature is 45 C which is normal i guess. So i was all happy about it but then i tried gaming and the pc shuts off even earlier than before, after 2 to 5 minutes of playing.

Ok tell me what you think and sorry for this long post but I'm really frustrated
Thanks a lot.

Mobo : MSI K9N NEO V2
Processor : AMD 4000+ x64 (something like that:p)
GPU: XFX GeForce 8600GT
2 GB's of RAM (1GB+1GB)
Windows 7

I have been having this problem for two months now.I press the power button , and i hear the fans and everything starting to run - and that is pretty much it.Nothing ever comes on the monitor.
YES - I have tried meddling with the jumper and the CMOS
YES - The monitor is plugged in and running fine ( I checked it by plugging in the monitor to my laptop )

Almost everyone tell me that the graphics card has gone to hell , some people tell me that the mobo is screwed , and the most likely theory is that my PSU has gone kaput .But if the GPU is broken , then i would have heard a beep , right ? The same thing is with the RAM - a beep . But i don't get any beeps.No abnormal sounds AT ALL.

My parents , being the asses they are , see this as a wonderful opportunity to make me study even more so they won't buy a new PSU.Fortunately , i have another PC and I am a bit afraid of meddling with the power supply.The older computer was assembled in 2003 so i wonder if the PSU from the older one is compatible with the new computer.

Please answer me - If i spend another weekend away from Team Fortress 2 or Facebook , I'll go insane :oZ

I really need some help with my PC. I have this power supply: Image: http://img215.imageshack.us/img215/5484/img1843n.th.jpg ... Hello, guys.
I really need some help with my PC. I have this power supply:

I have had it for quite a while now and it always kinda behaved well... I do not remember when it started, but more than for last year or so it was behaving strangely.
Basically, what happens is that when i shut down the computer completely, as in not hybernating or standby, the PC still "looks" working. I.e. the chasis and the CPU coolers are glowing and spinning, together with the front display on my case. It is not as loud as when it is working, but its still not really supposed to do that. I resorted to switching the power off on the back of the supply everytime i shut down. No other problems.
Today i installed ATi HD 4890, well, its specs say it needs 500 watt, and my supply has 575 watt, I thought it would be ok. I played on it for over an hour - all fine, no graphics issues, no signals, overheating or anything. All of a sudden the PC just shut down, three red LEDs started flashing on the GPU and all of the fans were spinning crazily. It took some shutting on and off until i could get the PC to boot again with no red leds on the GPU.
My specs are:
2.66GHz Intel Dualcore, a gig of ram, 2 sata drives, 2 optical drives and one chasis fan, before the ATi I had Geforce7900GS. I have got dual boot XP and Win7, but i dont think it matters.
To sum up, two questions: anyone has any idea why my pc would not properly power down, psu or motherboard? and is my PSU reaaaaally unsuitable for the new GPU i got?

I have the SpeedFan 4.39 installed on my computer. Been having some issues with overheating only when playing a high graphics demand game. I have five temps monitored by SpeedFan, HD0 and HD1 average less than 40C, temp 2 and 3 average around 40C also. Temp 1 is a different story, it will be around 53C until I load my game and then it goes up to 63C or a little higher (and sporatic computer freeze up :scratch:). My question is how do I locate Sensors 1,2, and 3 and what exactly does each monitor? Is there safe software I can download to tell me? All three say Chip VIA82C686, BUS ISA, Address $C00.

As it was starting the OS, the computer shut off completely. So, I pressed the power button to bring it back online. The computer turned on for just a moment, I could hear the fans running and the case lights turned on, but it immediately shut off. Then, it turned on and off again in the same fashion (but this time, I didn't press the power button or anything - this was happening automatically). This happened one or two more times then it turned off and stayed off.

Fully unnerved by this point, I tried once more to press the power button. There was no response/lights/fans or anything. I opened up my case and checked to make sure everything was plugged in, then used compressed air to clean out the case. I plugged it it and tried once more. Again, it turned on and off a couple times quickly then stayed off. I then unplugged it and came here. Any ideas what's going on? I can only assume this is a power supply issue. ]]> PSU and Overheating Issues jahuteskye http://www.pchelpforum.com/psu-overheating-issues/79774-turns-off-repeatedly-just-second.html http://www.pchelpforum.com/psu-overheating-issues/79751-computer-shuts-down-when-running-antivirus.html Tue, 27 Oct 2009 07:36:02 GMT Hi All Had some problems with special built 18 month old computer shutting down.

Had some problems with special built 18 month old computer shutting down. Decided to backup, format C:\, re-install Windows Vista and other programs. Also cleaned out inside computer where there was heaps of dust, particularly on the 2 fans.

Reasonably OK now apart from:

1. Sometimes freezes when using the internet;

2. When using BitDefender deep scan computer shuts down.

Any ideas would be gratefully received.

Thanks.

I would just like to check if this is a PSU problem. I bought a new PC last April. And since then, i have already had the PSU replaced thrice. I usually recognize it because, well, the PC doesn't turn on. THe LED Lights light up, although after awhile (about 10 secs more or less) it stops. And lights up again, then dies.

However, last Saturday (morning), my computer did that again. So i thought it was a PSU problem again. On Sunday evening though, it was able to power on. However, when i start playing games, it just restarts. and here's the problem, when it starts up now, it shows BIOS Auto recovering... THen, it starts up. I would just like to check if this is still a PSU problem or what.

THe last time i had my PSU repaired, the tech told me that it might be a motherboard problem.

Anyway, i cant provide technical details right now since im not at home. Just checking if you could provide any plausible reason for this pc mess *sigh*.

well here's my problem:

i bought a new computer few months ago, mainly for my 3d animation studies, so that means that it does some really heavy operations most of the time. But, even though i havent been using it so much, the last couple of weeks gave me some random restarts all of the sudden and now are getting more often and drives me crazy. So i opened the Asus Probe to check whats up (i got asus motherboard) and i noticed that everytime a restart occurs, my 3.3v is at 2.60/2.70 volt and everytime the 3.3v starts to drop, the PSU gets hotter and hotter.. my PSU is 400 watt if i remember right, it was default with the case (probably it sux)

**while i was writing this thread, it restarted at 2.65v and now its at 3.23, which is the highest value it gets**

So the restarts are from the bad PSU? if yes, which is a good PSU for a heavy system that must work at 100% ?

-------

-- CURRENT ASUS PROBE VALUES:
Vcore : 1.12v
+3.3 : 3.23v
+5 : 4.97v
+12 : 12.10v
CPU temp : 34c
MB temp : 35c

--my system config: Intel quad, 8 gb ram corsair (with the 3 ram fans), scythe fan for the cpu, asus motherboard, raptor HDD 10,000 rpm, quadro fx 550 gfx card, PSU default with case 400watt.

Thanks in advance and if u need more details about my comp's config, let me know,

Ok so I had a powercut (i get them every few weeks and theirs a switch in my garage that i turn back on and the power comes back) and my power supply blew up in this process, as soon as the powercut happened i went and turned the power back on, when i came back to my computer i could smell a sort of burning smell, and realized my power supply was fried.
So i got one of my older PSU's out which im 100% sure works, and I disconnected the broken and one and connected my older one, but the problem is that the PSU which is not connected won't work when I press the power button, I have neon lights inside my case and they turn on for a split second then off again. So its almost as if the power supply is working for a split second but doesn't seem to want to start my computer properly.

Help is very much appreciated.
