Next Step Any ideas what I can do next. What's the most cost effective (cheap) way to resolve which, or if any, of these components has been burnt out? If I use the current chassis, power supply, disks etc what options do I have to rebuild the pc, can I only use the MS6541 motherboard or are their substitutes that I can use?. Performance as such is not a requirement (although the initial problem was that the PC was too slow to be acceptable).

Feedback To confirm that I have not touched the wiring, in fact Im at a loss to know where the wiring is. The MOBO is MS-6541 v2.1

Response To confirm that I have not touched any wiring. I got the rompaq from http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareIndex.jsp?lang=nl&cc=nl&prodNameId=97106&prodSeriesId=96284&swLang=8&taskId=135&swEnvOID=1093#120 and selected ROMPaq for Evo D310/D320/D510 and W4000 SFF DDR (686O2 ROM)3.18 12 Jun 20030.8156K: 1m 512K: <1m3.16 A 7 Apr 2003 The version I had was 3.13 Can't give motherboard version etc till tonight but it is something like MS-XXXX v2.1 - definitely version 2.1

Still not working Ok, I tried what was suggested above. I isolated the motherboard from all drives, memory and power connections, and with no battery. I then replaced the battery, the large power connector and the 4 pin power connector. I reconnected the power supply but still get the same problem, when I press the button the green light appears immediately but no fans start. After a short time the green light goes out and becomes a red flashing light at a rate of about 1-2 seconds. Any ideas of what else I can try please?

CMOS Battery Regarding the previous post the battery you describe seems different to the one I have, the battery is like a large version of a watch battery that locates into a holder with a connector in the base and a clip on the side holding it firm. There are no pins/wires etc

Suggestions tried so far from Dalo I've done what you said by removing the circular battery and leaving it out for a long period of time. Now when I switch power on the power light on the front goes immediately green (doesn't need me to press the power on button) and then after a few seconds flashes red at about 1 to 2 seconds delay and thats it! nothing more happens. There is power on the board as I can see green lights but the fans don't run, there is nothing on the screen - any ideas what else I can try?

I have a Compaq Evo D310 that is rather slow. Also it has a 40G disk to which I have added a slave 160G disk. If I try and make the 160G master or the only disk then the PC comes up with a disk read error on startup. Someone recommended I update my BIOS to possibly help here. On startup hitting F10 I have noted that the bios is v3.13 and the rom is 68602. From the HP web site I have downloaded a rompaq to upgrade to v3.18. After I did this and installed it via a floppy I noted on startup that the new version v3.18 was sucessfully installed. After continuing on to Windows the PC ran ok for a few minutes but then went down. Now it won't start at all, if I press the power on button the light goes green for a second or two and then flashes red every one or two seconds. I've searched the web but can find nothing concrete to help, any body got any ideas what went wrong?. The only clues I found were power failure or ROM fail??? but I don't know how to narrow this down and resurrect the PC back to life.

Settings Thanks for the info over settings but I'll have to run with just one memory card because it's faster than two. Any ideas why two memory cards can give such as drop in performance than one?

Feedback CHECK that the RAM is the same speed if you add 2 different speeds of RAM it will ALWAYS run at the lower value - not sure how to check this Check that values in the BIOS are set to default for the RAM - the bios only has an option to set all defaults, not one just for RAM so it might be a bit risky Have you tried booting the computer with the only the new memory? - yes, either memory card on its own is slow but just about useable, together it is completely unusable Have you checked that the bios is recognising the new memory? - the BIOS shows 504M of memory Are there any bios warnings (beebs) when you boot? - no Have you changed your pagefile settings to account for the new memory? - not sure how to do this

Hi, I purchased a Compaq Pentium 4 2660MHz from eBay. Its slow to boot and to use and has a single memory strip type PC2100 with 256M of memory. I ran Crucials memory utility and it advised me to buy a compatible memory card PC2700. I found that once the new memory card was inserted that booting and using the PC was a factor of times slower even though System showed that the extra memory was being recognised. I sent the memory back and bought another memory card from eBay, type PC2700 at 256M. It had the same effect. I heard that there is some doubt about the compatibility between 2100 and 2700 so I bought another PC2100 256M memory card. I fitted it last night and immediately noticed again a serious degradation in booting up and in performance even though System says there is 504M of memory. Any ideas about this bizarre situation that adding more memory causes the problem that I am trying to solve. Any help much appreciated, Rgds Martin

Done It all works - thank you so much

Thanks ... ... but I've managed to download a driver for the display that works by searching for 82845G/GL/GV. Network still a problem though
