Have eMachine T6534 upgraded ram to 4X1gb, & 2 hard drives. Cpu installed with Artic Silver and is running hot (starts around 40 c and runs up to 62 c under load). Cpu usage hovers around 50% and goes to 100% all of the time if any processes are done. I don't have a lot of unnecessary processes going on. Tried a cpu from a identical machine that works great, and still has same problem with running hot. Could this be a psu problem?? or maybe the cpu fan is not functioning properly. I can hear it running fast on start up, then it slows to normal speed, then if I run any programs like PhotoShop or any games, the fan runs at top speed. Computer is off the floor and is cleaned out at least once a month to remove dust and any other buildup inside case. All sticks of ram appear to be working properly. Motherboard was replace from a MSI 7202 to an Asus A8N-LA, upgraded bios to 3.11. Could it be the drivers??? I don't know what else to look for. Any help would be most appreciated.

According the manufacturer site you can use max 4Gb RAM.

No. You have a 32 bit CPU. It will not run 64 bit software. You need a 64 bit CPU first.

Hi,

The freezing sounds like it's one of the components are bad. You need to do some testing of components that you can test. You said you increased your RAM to 2GB, Did you buy all new memory or did you add additional to your existing memory? Here's what components I believe could be causing the problem. It's either the memory, cpu, or possibly the hard drive (that is easy to test) Just run a chkdsk from cmd prompt and if it comes clean, then it's not the disk. The last component which is not typically the problem (but can be) is the motherboard itself could have a short. It's not software, or any virus, since you've restored, upgraded, an the like, that usually will wipe any viruses out. I for some reason get the feeling it's the CPU. You said it started from out of the box, and it's been randomly doing this for a couple of years. (your are a very patient person) I would test the CPU HEREs a free cpu tester. If it freezes during the test, then I'd say it's the cpu. If not then you need to start testing each componeant to make sure it's first a compatible part, and 2nd if it's in perfect working order.

Let me know how it goes.

Thanks

I agree...sounds like a power supply problem. Typically a bad power supply will not damage the motherboard. It should still be functional.

You power ratings are ok on the main power supply. But you should check the volts on the internal and see what is happening.

remove the 4 screws from the stand, remove the 5 screws from the back, remove the 3 screws from the bottom. The back will now lift off. There are 7 screws around a silver aluminum cover on the inside. Remove them and lift the cover off and you will see the ram. Also, not where the wires run under the aluminum piece so as to not kink or cut them when reassembling.

FYI, same instructions apply for upgrading the CPU, GPU, and Hard drive ( although the aluminum piece doesn't have to come off to change out the Hard drive). I have put a 1.5 Tb drive in with an Intel E7400 C2D cpu and 4 Gb ram. My next upgrade will be to an ATI HD 3650 MXM type II gpu. (actually already ordered one but it arrived damaged).

It is possible the power supply is now too small for the number of loads you now have.Not sure what your CPU is ,but I bet it is 80 watts just by itself. The minimum wattage requirement or the video card by itself is 300 watts.Add the drives,ram,fans and mobo and you way underpowered.

Hello,

motherboard replacement is depending on your current processor, memory, and video card:

Verify this site for your processor and motherboard matching.

My guess is that CPU fan, it there is one, is not working properly and your computer is heating up. Is it turning off, too, occasionally after a period of time? Suggest a new CPU fan.

I read the thread over at computing.net just now. I'm having trouble locating a picture of the internals of the Deskpro 4000 online but I know Compaq did some pretty non-standard things back in the day.
Yea, try upgrading the processor - it's not going to cost much to try. Much as WebsWonder commented, I've been throwing out everything below 2ghz at work.
The 2mb S3 Graphics was great for its day. Look around on eBay and find a PCI interface card with 8 meg of ram or better. An ATI 7000 series would be good n cheap but even a Rage 128 would be an improvement over what you have now.
I honestly don't know if upgrading to 333 mhz is going to produce smooth video for you. I upgraded my son's Compaq Armada 1750 from a P-II 333 to a P-III 500, bumped the memory up to the max 312, and installed a 7200 rpm hard drive. It streams video just fine on XP Home.
