Question Why is my Computer Suddenly overheating??

Well, I made a post a while back about me possibly having a virus/spyware because my PC constantly got all laggy with the mouse and then froze

Well, I reformatted, and it all went fine. Then, it went into the XP setup (graphical area), and did it there too! By this point, I knew it had to be a hardware problem. I rebooted and the BIOS thing said that my CPU temps were getting up @ 100 degrees F. Its never been this high before so I turned it off and put a couple of fans pointing at the CPU and vid card.

I restarted and the setup finished fine, no freezing. So here is my question: I have had this computer for over a month and these things had never happened. Why is my computer suddenly getting too hot to function NOW? What exactly have I changed and how can I get it back on track?

The heatsink is fine, the fan on the heatsink works, i applied thermal paste correctly, and its not a very hard processor to keep cool (AMD XP 2000+)

Any ideas?

May be time to flash that BIOS.

How exactly will upgrading the BIOS help?

Yea I'm with mackenzie.... What will upgrading the BIOS do for his heating?

As for your question about why it's heating up, how old is your computer, and do you have any custom fans in it? Like ones you out in.

Actually, forget what I said. I thought your CPU was 100 C!!! If it's 100 F, then you have no heating problems. I'm use to reading in Celsius, not Farenheit. If it was the other way around and your CPU seems cool, then the BIOS is all screwed up.

Is this a home built computer or a retail PC you got from the store? If so, then take it in for warranty purposes. I'm suspecting the hard drive. If you have a Startup Disk with the Scandisk utility on there, it wouldn't hurt to try it there. Try using another hard drive if you got one.

HAHAH if it was 100C he'd have like two minutes to turn it off before it lit a fire in his walls! lololol

Default Re: Why is my Computer Suddenly overheating??

hahahaha yeah... I think Id be worrying more about fire extinguishers than BIOS flashing

So, you think it might be hard drive related? I think that makes sense because I built the PC from scratch and I have been a little rough with my processor but I dont think that should make a huge difference on randomly freezing or not starting up... Ill look into another HD

I don't know if he is having heating problems. It's hard to tell when the PC won't even boot. But BIOS says 100 F, so it should be fine. If the heatsink is warm, but not hot, it should be fine too. I'm thinking just swap hard drives and if that doesn't work, then what else could it be? It did a RAM count at the beginning and he did get all the way to the installtion of Windows part, so don't know if it's RAM doing this. Video card? Hard to say. I was in the tech room, I would have enough parts to test each component in the computer.

Well, Windows did install after a few tries. It was random, but it did. It seems like if I leave the comp on for a long enough amt of time, then it will freeze.

But yeah, I am able to boot WIndows now, it just still gives me this problem!

After a clean reformat and still giving that same problem. That's wierd. I know at work, we would just take out the old hard drive, get another one (already been imaged) and pop it in the PC. If it didn't work, we would replace the whole PC (boss doesn't like us spending too much time troubleshooting a PC when we have a lot of new ones for spare).

Before you go any further, I'd suggest throwing your hard drive in a friends computer and backing up your stuff. I'm thinking it (could) still be a heat problem, at least to start. Do you have a PC speaker in your case, and if so, does it make any noise? Try and download the drivers you are missing and drop them in when you hook it up to a friends computer. This is a lot of work and the problem might not go away despite all the work. It's got to be a hardware issue...

About your problem Mackenzie, I wouldn't worry about it. It should say it's at 42 celcius right? 100Degrees farienhiet isn't too bad, just don't overclock, or you'll have a fire on your hands.

you might have to reset the bios. maybe ur settings in ur bios changed, like the frequency or voltage or something.

No. The bios has pretty much NOTHING to do with temperatures, unless your overclocking, or there is some strange setting thatmakes your computer run at intense temperatures.

the settings of the bios might have been changed, basically like "accidentally overclocking"

sometimes when you reset a cpu the bios will give you errors saying something is trying to be over clocked and really its more of a warning that don't do what your doing if its intentional otherwise don't worry about it. If you are going to post temps then post them in celcius even though most of us use fariegnhieght (I know its spelled wrong) in normal life in comp talking we use celcius. but 100 degrees f is not to hot by any means.. it can even be 120+ with full load but then u need to watch it. A Normal CPU shoud be around 30-39 just idleing, and no more than 60-65c with full load.. My p4 3.0 prescott (which are supposed to run very hot for pentiums) its about 39 with no load and 55c with full gaming.

Default Re: Why is my Computer Suddenly overheating??

Ok, thanks a bunch guys!

I'm getting a little confused... My computer works now, no freezing or skipping (still in the 40C range for temps on CPU) I put a different heatsink/fan in b/c I wanted to see if I could bring the temps down more and I noticed the skipping and freezing again! (by the way, just in case this helped: when my comp worked with no skips and stuff, I had put in TWO extra fans -- one on the chassis near the HD and one hanging down and facing the vidcard/mobo area. When I put the new heatsink in, I removed all of these because they were loud.) I restarted to see if the new heatsink was actually worse or something but the temps were DOWN to 33C!!

How can a heatsink/fan mess things up???

PS: On my BIOS load, I have System Temperature and CPU Temperature. What is a safe system temperature? I am averaging low 30s for system temp right now...

Please help! I have no idea what's going on... It was workin' fine for a while and now suddenly its back to skipping mode! It seems like the longer I leave it on, the shorter time I have to use it before it botches (and the longer I leave it off, the more time I have to use it...)

What is wrong with this thing??

If you can go to microsoft, download memtest.exe. it's a memory tester. If you can't find it on microsoft then just google it. Try testing your memory. Restarting on a computer can be caused by just about anything, heat, HD, Memory corrupt, motherboard screwed up somehow etc.... Put memtest on a floppy after downloading it and boot from the floppy, it'll run 6 tests continuously and it will tell you if anything is corrupt. Try doing a checkdisk on the HD. Have you heard any clicking or has the HD gotten louder recently? If so replace it. If not then you might want to look at your powersupply and upgrade. Then put all the fans back in so it can cool properly. After that, if you still ahve problems you might have to take it to get looked at or have one of your friends look at it with you. Somtimes it takes a new perspective to figure things out. Hope this helps.
