Question

Computer randomly shutting off

Hello!

So I have just began using an old computer again and for whatever reason, when i do certain things, such as watch videos, play games or visit certain websites it reboots, whenever it reboots it does it as if i normally would have rebooted it, along with that when i install more ram it crashes almost instantly, I'm unsure what is causing the problem and any help would be much appreciated

specs are
Lenovo M58

CPU : Intel Core 2 Duo E7500

Graphics card : Intel Q45/Q43 Express Chipset

Ram : 4GBS DDR3

If you need any other info please tell me and I will respond ! thanks for the help

Clarification Request
Are you mixing memory sticks?

Some very hard to diagnose crashes over the years have been mixed RAM. That is, unless you have no troubles, you don't mix. If it you have troubles and find mixed RAM you correct that along with (if it's old) do a deep cleaning of the heatsinks, fans and replace thermal compounds.

Some of this old gear won't work any longer so don't invest in these.

If you want, share machine details with the make, model PSU as well as a Web Speccy report.

Answer
2 things

Old computer means new thermal paste needed between the CPU and HSF. Boot into BIOS and watch the temps for a bit, see if they start climbing too high.

RAM is different matter. Some older computers need low density chips and can't run the high density ones. Also if two sticks of RAM are different speeds, the slower RAM stick may need to be in the DIMM 1 slot to use it's SPD to set the speed. Doing it backwards will cause similar problem you describe. Best is if all RAM chips are same speed and maker.

A few questions

so i have a few questions

If the computer only reboots when doing certain things, like streaming video or playing games, then can i still check the temp when doing those? if so i'm unaware of how, and also the computer still crashes with only the ram it came with, but the more ram the faster it crashes

"but the more ram the faster it crashes"

If your motherboard will only support 4GB of RAM, then that's as much as you can expect to use in it. Check the specifications of the motherboard online.

it can support 8

from what i know the mobo supports 8 gigs, either way i only have 4gigs in it right now and it crashes anyway

Time to supply all the PC details.

Look up. Supply the make, model of the PSU, the Web Speccy report and guess how old the parts are.
