iv just upgraded my Pentium 4 2.8 Ghz to a 3.2 Ghz HT.
Since doing that my system will totally freeze (mouse not moving, keyboard num lock light not working) and the only way to get out of it is pressing the reset button. Although if i put the old cpu back in the system works fine. It normally freezes between boot up screen and up to 3-4 hours, so it is totally random.
I'v looked around on the internet and found that it could be RAM timings or the power supply.
I'm not really sure what to do with the timings but i have borrowed a more powerful power supply but this made no difference. I put the old one in and overclocked the cpu to 3.4 Ghz, doing this actually stopped it freezing for much longer but will now go at 2-4 hours.
So im still thinking it could be something to do with the ram as the frequency of the ram has changed when i overclocked it.
My old processor was o/c to 3.15 and had no problems with that
A few other things i noticed: when the system freezes the hdd light will still keep flashing and could hear it working, also if listening to music this would keep on playing till the end of the track not just stop.
My full specs are:
VIA PM800DMS Motherboard
2x kingston DDR 1GB
256mb ATI Radeon HD 2600 AGP
80GB Maxtor IDE HDD
40GB Maxtor IDE HDD
Creative soundblaster Live PCI souncard
2x Sony DVD RW combi
if you need anymore info just ask
It might be a blue screen to really check go to:
Start -> Right-Click My Computer -> Properties -> Advanced System Settings -> Startup And Recovery -> There you should see "System Failure" Just uncheck the box that says Automaticly restart, Thats just for safety now to the real issue,
1st step: reset bios. If it work there were some wrong settings
2nd step: Check if your motherboard supports the new cpu, if not try updating bios
3rd step: Update drivers, chipset, graphics card etc
4th step: Try re-installing windows on another HDD if you have one
If non of those work look around on your motherboard and if you see anything that looks like this (Check link) http://upload.wikimedia.org/wikipedia/en/b/b9/Vp6_blown_capacitor.jpg
Then i'd say i have some bad news for you, Good luck and try everything i just posted
Is this your motherboard?
If you have not already done so, update the bios.
You should not update this computer anymore. Save up for something because it's extremely out dated and replacement parts will only climb higher.
Pentium 4 Prescot CPU HT (Celeron-D)
PM800DMS (Since Bios Version 4)--> A04 YES 3.2GHz
Thanks for the replys
I tried all the things that Zebben suggested, still getting the same problems. I have found that the system will most stable with my cpu clocked to 3.49 ghz (212mhz x16 multiplier) but the problem still exists. All drivers are up to date, bios is on most up to date release. I did not try installing windows on another hdd as i dont have a copy or spare hard drive at the moment, but i may try this asap as it could be an o/s issue.
All capacitors visually look ok.
yes this is my motherboard: http://www.jetway.com.tw/jw/motherboard_view.asp?productid=60&proname=PM800DMS
I have looked on the jetway site and the via site, they both say the motherboard supports this CPU.
i do know the motherboard is outdated but havnt got the money to upgrade at the moment, hopefully by the end of the year :D
Does it crash when you are not overclocking?
Can you take pictures of the insides of the case.
Yes it crashes the most when not overclocking, but less when i am overclocking
Maybe i should try out some more frequencys to see if it makes it more stable?
I can take pictures, is there anything specific you want taken?
After installing the new processor did you reformat? I know it is not necessary but I usually reformat to avoid any problems after installing new hardware, minus GPU, RAM, HDD / peripheral and PSU upgrades.
I didn't reformat, on first installation it said installing and then it completed no problems, then it froze
Try underclocking the speed of your memory. If it's 400 try 333 ect..
Sometimes when you install a new CPU you have to clear the CMOS. To do this the easy way just remove the motherboard battery for 5 minutes and then put it back and load the motherboard bios defaults.
I believe i may have stopped the problem, but i dont know if it counts as solved.
It now runs 100% stable for any amount of time with the CPU clocked to 3.39ghz (212mhz x16) and the voltage at 1.385v
Does this make it any clearer as to what the problem was?
