Computer slows down after 5 minutes of running

Alex Draghiciu · May 24, 2014

Ey guys, not sure where to post this. Ok so I got my PC, an old rust bucket but still acceptable for playing oldies. When I start it after a while of being off, the PC seems to run like super fast, if I start a game it'll load super fast and never lag. But after about 5 minutes of that, it slows down with no way of returning. I'm not saying that it's really lagging, but it's not working at its full power. I dunno what this is but I've had it ever since I reformated it the first time like 2 years ago. I'm curious what this is and how it can be fixed.

Other notes: when I start the PC it makes a loud humming noise for about 2 minutes, the computer beeps pretty often (kinda like that beep from the hard disk, when you're like lagging or something)

If you guys need to know anything else, let me know. Thanks in advance. :*

1. Post your build - per forum guideline.

2. Download and run HWInfo - Sensors then post the results.

This often happens because the cpu gets too hot. The results will tell us if that's whats going on and maybe why.

Your CPU is probably throttling itself so it doesn't get too hot.

Sorry guys. My system has some sort of malware that doesn't allow me to download certain .exe's like Bittorents, Java Runtime or any kind of Antivirus. It won't allow me to download HWInfo either. If you can tell me any alternative to HWInfo I can give you the data.
I didn't find that forum guideline but here's my specs:

OS: Win XP SP2
CPU: Pentium IV 2.4 Ghz
RAM: 1.5 GB
GPU: ATI HD 3450 512 MB

If you can, download RealTemp. Run a few applications, use it normally. When it starts slowing down, check your CPU temps. The malware could also be the cause of your problem

Wait! I managed to find a zipped installer. I ran the sensors and here's the results.

I have that virus from like maybe a year. It survives reformats and I don't how to get rid of it. But I had it before when the CPU run smooth and didn't cause any problems.

CodenameHaswell · May 24, 2014

The malware might be in on a separate drive, or in your recovery partition (if you have one). Your CPU is at 80c, which is WAYY TOO HIGH when at idle. When did you purchase this pc?

i7Baby · May 24, 2014

You can see from the HWInfo results that -

1. Your power supply needs replacing - 3.3V is a bit low at 3.0-3.1V, 5V is OK, -12V is at -9V
What power supply make and model do you have?

2. Vcore is way too high making the CPU too hot. Reduce Vcore by 0.15V now!

CodenameHaswell :

Im not really sure about the malware. I might be from my phone, where I keep my ethernet driver. I bought this really cheaply from a neighbour like 2 years and when he gave me this it was running like super smooth, and he didn't even have any antivirus or antimalware on it. The PC is way older, I think like 2004.

i7Baby :

Well, I cracked it open, and here it says:
SWITCHING POWER SUPPLY
MODEL: ATX-450W P4

Also, it's aftermarket. It's got the price on and the year it was bought: 2010. Oh, and how do I change the Vcore?

i7Baby · May 24, 2014

So replace the power supply - as I said. Get a good quality one eg Antec HCG 520M, XFX 550, Seasonic 520

Change Vcore through the motherboard UEFI or Bios if you don't have UEFI. Read the mobo manual.

Ok guys, thanks for all you help.
