You have run the repair routine, reset the settings, even reinstalled - and Chrome is still slow, still crashing. At some point the honest conclusion is that Chrome was never the problem. This page names the impostors.
Four PC-level faults routinely disguise themselves as Chrome problems: too little RAM, a drive quietly failing, security software fighting the browser, and heat throttling the whole machine. They survive every browser fix because they were never in the browser. The tests below are short and conclusive - one cross-browser check, one look at Task Manager, one drive health read - and they tell you which patient to treat.
Before the second reinstall, run the only test that matters: open the same heavy sites in Edge or Firefox. If they stutter, freeze and crash the same way, stop fixing Chrome - the fault lives underneath the browser, in the PC itself. Browsers are where PC problems become visible, because the browser is what most people run all day. A fault that follows you across browsers was never a browser fault.
Open Task Manager's Performance tab and look at total memory while Chrome feels slow. If the PC lives above 90 percent, Windows is swapping memory to disk constantly, and every program - Chrome first, as the biggest - drags. On a 4 GB machine this is not a malfunction; it is arithmetic. The honest remedies are closing the other heavy programs or fitting more RAM. No Chrome flag, cache clear or repair script changes how much memory a PC physically has.
A failing hard drive wears a perfect Chrome costume: disk pinned at 100 percent in Task Manager, freezes of a few seconds, pages that load in bursts, a slow boot as well. Check the drive's health with its SMART status (a tool like CrystalDiskInfo shows it plainly - treat a Caution or Bad verdict as the real diagnosis). A mechanical drive in decline makes every program look broken, and it will not be talked out of it by a browser reset. Back up first; replace the drive; the browser fixes itself.
Security software hooks itself into Chrome's processes - and when it is outdated, doubled (two suites installed at once) or simply buggy, the symptoms are Chrome crashes, STATUS_ACCESS_VIOLATION under Aw, Snap, and pages blocked at random. Ask the timing question: did the trouble begin when security software changed? So-called PC optimizers and registry cleaners belong in the same suspect line - they delete and rearrange things Chrome depends on. One clean, current security suite is protection; the pile is the problem.
Dust-clogged fans and dried-out cooling make a PC throttle everything after twenty minutes of work - and recover after a rest. That time pattern is the signature: software faults do not heal with a tea break. So settle every mystery with the scope question. Browser-only symptoms, on a cool PC, with other browsers healthy - fix Chrome. Symptoms everywhere, in every program, growing worse under load - fix the PC. The case pages in this guide cover the Chrome side; this page exists to stop you repairing a healthy browser on a sick machine.

Watch Full VideoTwo signs together: the same faults appear in another browser, and Task Manager shows memory or disk pinned near 100 percent. Either sign alone is a hint; both together are the verdict.
Yes. Security tools inject themselves into Chrome's processes to scan traffic and downloads, and outdated or doubled-up suites are a recognised cause of Aw Snap errors, including STATUS_ACCESS_VIOLATION.
On a mechanical hard drive, ordinary Windows services plus a browser can pin a slow drive - and a failing drive pins itself doing almost nothing. Check the drive's SMART health before blaming any single program.
