hi i just built a new comp. Its a 1 gig athlon thunderbird with a kt7-A raid mother board. my problem is with booting up. when i turn my comp off at night then come home from work the next day my comp wont boot. the screen stays blank it doesnt beep nothing. sometimes it shuts off itself when i try to boot. this only happens when i leave it off at night then turn it on the next day. if i shut down then restart right away it boots with no problem. could this be a power supply issue? also my comp hangs from time to time. i think that is the power supply to.

Two things to look at.
1.What size power supply do you have? ( Need 300watt or larger)
2. What do you have your bios setting for the power button set to?
( setting to suspend may be at fault)

i have a 300 watt power supply. what should the power management setting be set to.

In the bios.

I have them set to user defined.
I also have the power button set to power off on button push.

In windows control panel you can set them to save power the way you prefer

mine is also set to user defined. my suspend and doze are disabled. so you think my problem could be the power supply

When I first built my system it had 275 watt then a 300 watt.
It now has a 425watt.
It only hung when the 275 was installed and once after installing new memory.
I can say the 275 was the problem the first time.
The second was a miss match on the new memory.
The bios reported a system error and booted in safe mode( ie: 750 mhz)

I think the best thing to do is grab a larger power supply and give it a try.
Especially if the system is loaded .
BTW. My system is over loaded. Hence the 425watt.( Wish I had one more PCI slot and not the worthless AMR slot)

Another possibility is a bad mother board http://www.PCGuide.com/ubb/frown.gif
If it's isn't completing the post or in your case even starting it (no Beep or video)

Try reseating the video card and memory chips. Ground yourself to avoid static electricity.

I'm wondering if a CMOS battery might be an issue, but I doubt it if you don't get an "Invalid Configuration" message. getting no video or beeps makes me think it's a bad connection somewhere. Reseat all cards, and maybe try a power supply too, I'm not ruling that out...

So many idiots, and only six bullets...

the computer sarts when i turn it on it just doesnt boot up. all the fans run and everything. also the only way i can get it to boot is when is switch the voltage on the power supply to 230 then back to 115 while its still on

I think that is an almost certain indication that the power supply is too small for the job. I would not recommend that others try changing the line voltage switch while energized.

Friends don't let friends install Windows ME

soemtimes when i turn the comp on it beeps twice then turns off.

Power Supply http://www.PCGuide.com/ubb/biggrin.gif Even if it is a new power supply, it could be defective - ie not switching right or supplying enough juice @ startup. When you DO get the system up........be sure to check in the BIOS (setup) to see what the cpu temperature is......some of what you posted sounds like a toasty cpu as well. You want to be very careful with a Tbird @1000 mhz......they cost a good bit to replace and overheat in less than 10 seconds if not properly cooled.

I'm putting a new Fat32 partition in my Head Drive...hope it speeds me up.......

its running at about 125f. is that around what its suppose to be

You very well may have two problem conditions happening here, but I think you have to address the temperature situation fast! The CPU cooling fan is either running too slowly or has stopped, or you need to check the heatsink-to-CPU contact and possibly remount with thermal "grease". Whatever, 125F is way too hot -- recommendations temps are below 90F.

how many rps should the fan be running at. right now its running at about 5200 rpms. please let me know

also could this heat problem be due to the power supply. it might be producing too much heat because it is defective. the heatsink i have on there now is a heat sink for a 1.2 gig athlon wich is beyond what i need.

Sounds like the fan speed is OK, but if your temps are still in the same range, you need to do some further investigating. In the meantime, I'd advise you to turn off your system, open the case, and set a small table fan in a position to blow air into your case toward the processor area. But I'd also recommend that you run your system as little as possible, because overheating can trash your CPU beyond repair! I still suspect there is not good contact between the CPU "slug" and the heatsink, but we need an experienced Athlon guy like Randy to see this thread and evaluate the symptoms. A few more questions -- Are you overclocking? Are you sure the jumpers for CPU and bus speed are correct? Do you have any other fans inside your case? Is the power supply fan running when the system is on? I was surprised to read earlier that you had flipped the PS voltage switch to the 230-volt setting, especially while the power was on. Frankly, I'm amazed it didn't go snap, crackle and pop! Since it didn't, that may be a good indication that it's not working right. When all this is resolved, you may need to replace it. It seems from many posts in these forums that Power Management settings are better left disabled or off, both in the BIOS setup and in Windows. It's just as easy to power off the monitor with its own switch and let everything else run if it's only for an hour or so.

i am not overclocking. tomorrow im going out to buy an 80 mm fan for my case maybe that will cool it down also ill pick up some thermal greese and re set the heatsink on the processor. i also just ordered a 350 watt amd approved power supply. i hope this will solve all of my problems. if anyone else has any further comments i would greatly appreciate them.

also the power supply fan does run when it is on. im pretty sure the bus and cpu jumppers are set correctly. i double check in the morning. they should be because i never touched them. my bios has a softmenu system so i was able to set everything from there

You CPU is running WELL within the specs of AMD for that chip....they can go all the way to 180+ deg. F and be OK; however, my experience is that the cooler the better...(ideal for that chip would be about 110-115 deg. F ). My fan for a 900 mhz Athalon runs @ 6600+ rpms....I'm usually at about 106-109 deg. F and I dont have a case fan. YOU SHOULD GET A CASE FAN FOR SURE AND A BETTER CPU FAN http://www.PCGuide.com/ubb/biggrin.gif
Be VERY careful with thermal grease....ONLY A VERY SMALL AMT (as in a film of it)does a better job than a whole lot.

thanks for the info randy im ordering too 3 inch case fans as i speak. that should keep the temp down any way

when all this happens i get three beeps one long two short. does this mean the video card is bad. and if so would this cause my boot up problem
