My pc often functions very very slowly.It has a 128 Mb RAM with 1.80Ghz processing speed. What to do?

No that memory is not compatible. The Precision 350 uses memory called RDRAM aka RAMBUS.

Here are the speeds and sizes that are supported.

Memory modules supported PC800-40: 64-, 128-, 256-, 512-MB, non-ECC or ECC

PC1066-32P: 128-, 256-, 512-MB, ECC and 64-, 128-
,256-,512-MB, non-ECC

Minimum memory PC800-40: 128 MB non-ECC and ECC
PC1066-32P: 128 MB non-ECC and 256 MB ECC

Maximum memory PC800-40: 2 GB non-ECC and ECC
PC1066-32P: 1.5 GB non-ECC and ECC

1st try to exchange the cards in the slot.
2nd try another card
3rd ur RAM slot may not be ok
4th ur RAMs may not be compatible
5th ur new RAM card may not be ok
use same type of RAMs, and same size...
if u have 256, add 256
if u ahve 128 add 128
if u have SDR then dont add DDR
getting compatibility is little difficult...
some times no combinations can work...
note...technology keeps changing...so a old RAM card that was bought years ago may not be compatible with a new RAM card....
even i got all my old RAM cards(256+128) removed and got 2 - 512mb of the same type fixed...even i had issues with my RAMs for 6 months...

I am glad to hear that your PC is running well. If you need any help again in the future we will be here. This is something we like to do, so there no having to tolerate at all. Only us helping you to understand your problem.

Yes, but it will be somewhat slow on such a old computer. I would recommend getting a new computer or buying a newer used computer, for example from ebay.

Looking at the manual for this motherboard your maximum ram is 512mb in two sticks of 256mb each. Speed rating is pc133 (maximum). You may struggle with the external hard drive as you only seem to have usb 1.1 and not usb 2.0

most be your both ram FSB is not same , if yes you need same FSB ram

First uninstall the printer driver and restart the machine then again reinstall the printer driver using typicall settings , after installing the driver again restart the machine then check

first you check that your ram version.... i means it is compatible with your motherboard...if still prob remains then remove your all ram insert 128 mb ram then restart the system....... upgrade ram should fallow frequency of 512 mb RAM are same as 128 mb ram freqency........if mismatch is occured then it did nt wrked correctly...

it's 100 other info as follows:

Component Attributes RAM (standard) 64 MB SDRAM standard Maximum 256 MB (2 x 128 MB DIMM) Speed 100 MHz synchronous Sockets Two 168-pin DIMMs Size 16, 32, 64, and 128 MB DIMMs Type Supported SDRAM, 100 MHz, Intel PC SDRAM unbuffered DIMM specification, revision 1.0 compliant
Cache Level Quantity Level 1 (Primary) 32 KB (on processor) Level 2 128 KB (on processor) Upgrade Sockets None

Check the configuration of your system, it probably supports 128 MB of RAM at max.
