When trying to turn on my pc, it doesnt turn on, i push the power button the system turns on as if power, CPU fan starts up and all, but there is no BEEP, and monitor stays off, it just hangs there and thats it. you have to turn it off the turn back on for a few time (it varies really can take 1 min to 30 min) then it might beep and turn on. Could it be an issue with RAM.. i put in a 512mb (pc2700) and a 512mb (pc3100), could this be the issue? but before u answer that if i remove any RAM stick it still does the same thing? what could be the problem?

hmm.. for one, it could be ur ram.. check whether you have placed it correctly.. for anothr, it could be ur BIOs. Did you update your BIOs? Also, when did the problem occur? Only after you isntalled ur new ram?

 

[mattym]

yeh it started to happen after i put in the new RAM.. but not much only occasionally, wouldnt turn on, now everytime u try to turn it on it wont, u have to try for a while on and off then it might come on.

i took the RAM out and tried it how it was before and still no go,
unplugged the IDE cable from my second HDD still no go.

Do you think updating the BIOS will help? even though it doesnt even get to that stage yet.. (remember when i turn it on, no BEEPS sound just the power comes on eg, FAN, CPU fan, LEDs but thats it no activity what so ever) ??!!

 

[kaerloche]

hey.. hmm.. then it's strange.. cos if it's ur ram, then your PC wont switch on at all.. If I'm not wrong.. hmm.. dont update your BIOs.. it's complicated.. and one wrong step and your whole comp would be gone.. hmm.. are there any error mesages when you start the comp? Also, have you tried installing back the old ram into ur comp? Doesit work?

 

[mattym]

no ive got the old one in along with the new stick.. i take out the new stick and leave the old one in and still no go...

there r no error messages, cus it doesnt go through any BIOS activing or POST. no BEEPS aswell. the monitor doesnt even switch on.

I had the exact same problem months ago and still nobody has been able to figure out what is wrong. I took it to a shop for a diagnostic but they refused to tell me what was wrong until I paid them over $130 to fix it. Apparently all they did was fix my old crappy PSU but when I got the computer home nothing had changed. I took it back, they kept it for a few weeks, only to finally tell me that they didn't really know what was wrong (they said they "thought" it was the motherboard), and suggested that I just leave my computer on all the time. Although I should have blown up their store at this point - or at least asked for my money back , I just wanted my computer, so I took it home and once I got it started up I just left it on. That worked for a while, but now my computer just freezes up anytime I try and do anything more complicated than surf the net. It seems very difficult to pinpoint the problem and fixing it would end up costing more than this computer is worth (if it got fixed at all) and I am reluctant to just start buying replacement parts only to find out that it wasn't what was causing the problem.

I hope you find a solution to this problem, because nobody I've talked to yet has a clue. Some say power supply, some say hard drive, some say motherboard, some say processor, some say heat sink, and some say RAM. So at least I'm pretty sure it isn't my CD-ROM or internal speaker........If you have the resources, time, and skill that I do not, you may be able to figure it out through simple process of elimination. Good luck.

...."i put in a 512mb (pc2700) and a 512mb (pc3100), could this be the issue?"

First off, find out the actual type of memory that your motherboad wii support....can not run different type's'

Unplug your puter from the back (power supply) then open the case and remove the battery. Doing so will reset the BIOS to default settings. Let it set no less than 10 minutes. I have let mine on occassions set like this over nite.

Then install the battery and hook up the power cord and go from there.

Never attempt to 'flash' the BIOS unless you know what the ramifications are.

Good luck.

i`ll look into it further and post a conclusion if i dont throw the pc out the winodw.

Or simply use the clear cmos jumper if available.

I have the exact problem as of tonight with my son's hp pavilion 7920. He bought a 256mb dimm of sdram, which appears to be the correct type; he first installed it next to the existing memory, powered up to nothing. I have been working on it all evening; took the battery out, let it sit 30 minutes or so, replaced the original memory and removed the new one, same results. I am stuck, don't want to take it into some rip-off shop like others have. Has anyone found a solution yet? It must be the RAM, since it was working fine right up until the point where he installed it.

Sounds like interrim connections on one or more components. Try securing all the cable points, especially power, and all the cards as well. Also check and see if any jumpers have been tripped or if any of the componenetd have fused (the metal legs will appear to have melted onto the board)

i'm pretty sure i re-seated everything possible. It does seem like power because the mouse, keyboard and monitor all stay off, while just the fan runs. I took out the video card because he's had trouble with it in the past; turned the power on, then the light came on in the front as though the hard drive was at least trying; put it back and no light. So maybe the video card got destroyed? but why wouldn't the mouse and keyboard at least come on? This is most perplexing. thanks for the advice, i'll check for fused components later.

 

[spdykat]

I answered my own question; if the video card is fried, the boot sequence will hang while looking for video, right? so it won't proceed to discovering the mouse, keyboard, etc, thus they aren't coming on.

 

[kaerloche]

perhaps.. do you have another video card? Maybe the cooling system of ur video card died.. and thus.. your card fried.. it's a possibility.

 

[spdykat]

don't have another one that will fit into the socket. that's the next step, scavenging.

i remembered it has on board video, so took out the bad video card, hooked the monitor to the on board video and voila, it's booting and looks ok.
thanks for everyone's responses and help.
